General Motors' autopilot department, Cruise Automation, is planning to Air Suspension set up an internal taxi service for people outside the company to get a small part of the automakers involved and test their technology with the public.

Cruise's plans for public beta testing are at an early stage. General statement Milin Mehta declined to discuss the specific timetable and said it needed regulatory approval. The Cruise department also declined to comment further on this future business plan.

The taxi service called "Cruise Anywhere", just through a mobile phone application, people can ride it to San Francisco everywhere. Cruise Anywhere fleet cars are converted to Bolt electric cars, these vehicles equipped with the necessary sensors, computers and software. At the same time, each car's driving seat is also equipped with security personnel (legal requirements). Most of the time in the automatic driving state, the security officer will only be involved in an emergency situation.

Cruise Anywhere is still in beta and is therefore limited to employees in San Francisco.

In May of this year, Google's parent company Alphabet's autopilot company, Waymo, announced plans to test with the taxi service company Lyft. Alphabet is currently considering investing in Lyft.

General Motors already owns the shares of Lyft and plans to test its autopilot on the Lyft network.

Cruise is expanding the autopilot test outside of the company and still needs to configure the driver to facilitate the need if necessary. At the same time, the expansion of this business will require a generic re-expansion of the autopilot vehicle Chevrolet Bolt.

At present, only a handful of companies are providing autopilot car services to the public, including Alphabet, Uber and start-up companies nuTonomy.

In the ever-changing climate of the city, it is difficult to drive the car automatically because adjustable coilovers it must learn how to avoid "catch" the traffic jam and storm. Developers are also testing passengers to reflect the autopilot.

Testing autopilot services means GM is exploring future modes of transport, including the production of cars and autopilot technology, through its Maven service to provide car sharing and carpool services.

GM launched a new car sharing service Maven at the beginning of last year, allowing users to rent cars on an hourly basis and pay by hour. Maven users no longer need to use the car keys, only through the smart phone Turbocharger can be seamlessly interconnected with the vehicle. They can use the brand's mobile app to search for and schedule vehicles by location or vehicle type, and unlock the vehicle via a smartphone. At present, Maven has connected Lyft, Uber users, to provide services for them.

2070 China Automotive Industry Development (TEDA) International Forum Turbocharger held in Tianjin, more than 1,000 domestic and foreign industry elite in this heated debate hot topic.

Introduce the planning direction of new energy vehicles.

In the Guangzhou auto show in 2015 when the Geely Group officially released the next five years the new energy product strategy, is the blue Geely action, the goal is to 2020 when Geely 90% of the cars are new energy vehicles. To this goal, Geely main technical route EV, PHEV and HEV, which is also consistent with the country to vigorously promote the line. We rely on Geely's existing 3.0 and the next new 4.0 modular modular architecture, vigorously promote the implementation of the new energy strategy, our planning is plug-in and hybrid sales accounted for 65%, pure electricity Accounting for 35%. Geely wants to allow consumers to buy hybrid or plug-in hybrids at traditional car prices or close to traditional car prices and achieve sales targets.

Next to the main three technical aspects, the first is the battery. New energy vehicles, especially the popularity of pure electric vehicles, we all know that the first is certainly the battery energy density and cost of the breakthrough as a prerequisite. In the future for a long period of time a higher single mileage is our new energy product development process to pursue a very important indicator. Through the upgrading of the battery material system, continue to enhance the updated energy density, without increasing the size of the battery pack and the weight of the premise can make our vehicle has a higher driving range. Compared with the traditional lithium battery, solid-state battery with energy density, good security features, we expect that by 2028 when all solid-state battery technology can mature, can be carried in the vehicle above the application.

The following chart is mainly from our current application of flexible battery pack based on the estimated 10 years of battery development planning line, assuming that A and B-class pure electric vehicles, for example, we expect to 2021 Able to reach 600 kilometers of driving range, to 2028 is expected to reach 800 kilometers of driving range. In the modularization and platform of the battery, Geely new energy vehicle product planning is modular and platform for the layout, large and medium-sized car with different architecture programs, such as we and Volvo jointly developed CMA platform architecture, will The whole system is equipped with new energy platform. Different vehicle sizes, different body structures, including differences in demand for driving distance, the platform will greatly shorten the development cycle, saving development costs.

For example, we in the battery pack platform, inside the module and high-voltage electrical components and battery management system is fully platformable. With a similar shape of the battery pack we can achieve a different driving range and energy management methods, you can ensure that the same architecture under the vehicle platform changes are minimal, but also can greatly save the development costs of the battery pack itself. Of course, this for the downstream suppliers should also be a more economical program.

Below the left side of this figure shows the Geely PHEV battery system modular and universal program, is being implemented. For the battery pack of the lightweight, we cover the battery pack with a non-metallic materials, the next tray with cast aluminum and aluminum materials to the king of luxury, for example, we changed the box after the aluminum box weight Reduced by 47%, the weight dropped from 76 to 40, in the AEDC under the conditions of Emperor Hao EV pure electric driving range can reach three hundred kilometers, the battery pack weight loss effectively enhance the new generation of Emperor EV continued mileage, follow-up we will Have launched a higher continuous history mileage of pure electric vehicles.

On the right side of the main embodiment of the battery pack and body integration program, the left is the battery pack installed directly on the threshold, the battery pack on the body for effective support, to enhance its anti-side touch performance. There are many batteries in the middle and the seat connected to the battery pack and body connected to improve the vehicle's strength and stiffness.

On the right side of this figure, the body and chassis design takes full account of the battery pack and battery energy requirements, the battery pack is completely covered with the floor to maximize energy. For pneumatic systems, the integrated technology of motors, reducers and inverters is the current mainstream development direction. It is expected that by 2021 the motor and point reducer, the development of the inverter will make our products more energy efficient and environmentally friendly. With the output of the hub motor, the slowdown technology can matured to further reduce the size of the pneumatic part, thereby enhancing the vehicle power and driving range in the motor controller, the application of wide band gap material will become the new inverter Step-by-step development focus direction.

New materials The application of new technologies to enhance the peak and adjustable coilover continuous performance of the motor, it uses the future route we expect is the winding of the flat copper wire technology to reduce the noise to enhance the low-speed torsional zone efficiency of the core stacking technology will be in the future Of large-scale application of the product. And with the silicon steel sheet material for further production applications, the motor power density will be further enhanced. For example, now synchronous motor efficiency to 99%, our goal is 98%.

At the same time as the new cooling material for further application, the motor electric rotor effect will be further improved to improve the motor running capacity to increase the sustainable operation time, coupled with new materials and new technology applications, the motor power density we expect from 3.2 kW / Raised to 5.5 kW / kg.

The following describes the control system, thanks to the current highly integrated structure design to further improve the power density further miniaturization, at the same time each module manufacturers to vigorously promote the new material of silicon carbide power module development and verification, by the intelligence of the power The device can support higher switching frequency, further optimize the motor control performance, and compared to the current common silicon power module before the silicon carbide material can greatly inhibit the module loss, probably at 30% so the new material material application will Its quality leap, while bringing the installation more simple, more reliable products, system security will be further improved.

In addition, we are also concerned about the self-encapsulated power module, and now some manufacturers are also applied, some related performance has also been a preliminary recognition, we expect that by 2028 to 2030, 80% should use independent packaging module The Next to introduce the charger-related, charging time is short, cost-effective, will become the major car prices and market pursuit of the goal. Car charger will also be planning for this high-voltage junction box, CDC module charging and integration, and the future will gradually turn into deep integration, from the power, components and other aspects will greatly reduce costs. This year we have achieved in the Imperial EV 6.6 kilowatt high-voltage charger, the next two years the charging system will achieve more power car key machine to high-voltage junction box DCDC physical integration, the use of functional integration and power module reuse program, the overall Efficiency and performance can be improved to further reduce development costs and direct costs of the product.

We expect to achieve in-vehicle charger, PDU, DCDC depth integrated charge power of 40 kWh or even higher by 2020 to 2025.

In the wireless charging technology we have done some work, wireless charging technology should soon be able to market-oriented, this technology and the combination of automatic driving to solve the problem of automatic parking charging for users to show better convenience, wireless charging High-voltage alternating current completely wrapped in the charging device, no exposed high-pressure horn, and fundamentally solve the conduction charge of human safety hazards. Wireless charging system and the transmitter and the absorption of the physical connection just right to circumvent the life of the charge and discharge problems, Geely in September 2016, the first successful debugging of the first generation of wireless charging function, power up to 6.6 kilowatts, Industry well-known charging service providers to discuss the relevant industrial technology program, and in the discussion of industrial technology standards. Is expected to be achieved by 2020, wireless charging of the production, to 2025 to achieve wireless charging technology and car charger integrated program, and put into mass production, when the wireless charging technology will become mature, wireless charging power conversion module and the car The charger to achieve reuse to improve utilization.

I am also committed to Geely Automobile will soon provide users with a shorter charging time more convenient way to charge longer driving range of new energy vehicles, but in the field of wireless charging there are three more need to pay attention to the problem.

One is the energy transmission equipment and receiving equipment between the precise Air Suspension positioning problem, which is our combination of parking technology to solve, there is the suppression and prevention of battery harassment, especially for similar to the pacemaker harassment problem. The other is the efficiency of the collection and delivery, the current efficiency relative to our conduction charger efficiency is still far worse.

Simple to be summed up in the battery, from the energy density, life mileage increase, modular, general, lightweight, integrated is our technical line. In the motor is to improve the motor power density, improve vehicle control efficiency, the charger is a multi-function controller integrated to improve the wireless charging technology, in order to enhance the performance of the three systems. Geely also in the industrial point of view in the global introduction of sophisticated technical personnel, is committed to building our own new energy R & D team, shaping a comprehensive professional three electric technology talent echelon, to promote the core of the three systems manufacturing program, Technical level of improvement, and always firmly with the idea of ​​creating excellent Chinese brands, unswervingly achieve the 2020 blue action goals, to fulfill our social responsibility and mission.

Germany's first car, also the world's first car, Carl Turbocharger Bentz at the end of 1885 successfully designed the "Mercedes-Benz No. 1" prototype, and in January 29, 1886, the Royal Patent Office in Germany success Applied for the car's patent, this day is also recognized as a car birthday.

China's first production of domestic cars you know?

This "Father" liberation CA10 was born in 1956, C is the first letter of China, also represents Changchun; A is the first English alphabet, said the first. Its main components such as the engine, body, chassis are FAW own manufacturing, although there are some accessories, accessories purchased from the factory, but for the then backward and poor China, has been very rare.

This CA10 is basically imitation of the Soviet Union's Gis 150, while the Gis 150 is imitation of the US military million machine factory manufacturing KR11 models.

Imitation to imitation, but it was at the time the national total output of half of the car, 30 years, a total of 1.28 million production, than many domestic car prices but also cattle X! At that time there was a car CA10, certainly not rich is expensive, was a lot of young people dream car.

In the front of the liberation of the car because the color contrast problem is particularly eye-catching, five-star represents China, and the wings of the eagle on behalf of the FAW.

The lights are tungsten filament lights, do not know how far can be, and a small turn the lights, it can only give the car to the opposite.

The front wind can be opened, using an inverted wiper, it is said that this can increase the driver's vision, in the big coffee does not seem to increase the number of vision it.

Roof set up a "anti-collision wooden bar", the purpose is to prevent cutting rub, rotten nor distressed!

Interior part of the figure, at a glance, there is no comfort at all, now BJ212 adjustable coilover is such a thing, because this is not a family car, do not need to consider the passenger experience. Black tape wrapped around the steering wheel is to increase the friction, but the seat is decorated with a leather! This is now a lot of domestic cars have not done it!

Classic hand-cranked windows, how to pretend advanced? Eyes looked out the window, and then shaking the handle evenly, and so the uniform speed of the window, the moment into a key lift ~

Power equipped with a 5.6-liter 6-cylinder engine, the maximum power of 90 horsepower / 2400rpm, matching 5-speed manual gearbox, the maximum speed of 65km / h, carrying capacity of 4 tons, 100 kilometers fuel consumption 29L,

The car is used in the 4x2 rear drive design, rear wheel dual tire design is to ensure the cargo volume, rear suspension for the multi-leaf plate structure, and now the truck is not much different.

But this CA10 ignition is the need for skills, need to hand the cylinder in the mixed oil and gas compressed to the flash point, the engine was able to start, and shake to also need a lot Air Suspension of effort, not young and old drivers are difficult to ignite, Let alone steal the car.

With the development, this goods has also been transformed into a variety of functional vehicles, crane trucks, emergency vehicles, fuel trucks, water trucks, dump trucks, trucks, trucks, refrigerated trucks and closed car trucks Etc., can be modified potential

Double clutch transmission in the low speed prone to frustration,Ignition Coils the main reason is the dual clutch transmission without hydraulic torque converter, but rely on friction directly to the torque transmission to the drive shaft, although there is no hydraulic torque converter to bring the power loss, But the friction plate is not the role of hydraulic torque converter buffer, the two sets of clutch plate in the shift operation, easy to produce a sense of impact.

Similar to the manual gearbox, there are similar semi-linked states in the power transmission process of the dual-clutch gearbox, in order to reduce the wear of the clutch plate. So TCU software engineers will let the clutch plate and friction plate as soon as possible, this time if the engine output speed and transmission output speed difference is relatively large, there will be frustration.

One solution is to optimize the hydraulic control unit, through the hydraulic Air Suspension cylinder to push the clutch plate to friction, reduce vibration, thereby reducing the generation of frustration. Volkswagen code DQ200 7-speed dry dual-clutch gearbox using mechanical control arm and sleeve squeeze diaphragm spring deformation, from the structure point of view of its transmission efficiency is higher, optimized for the hydraulic system to promote, to better filter vibration, Thus further reducing the generation of frustration.

Software control, you can optimize the dual-clutch transmission of the shift logic, through the actual shift data to determine the correction of bias, can help double-clutch transmission torque and separation of the control position more accurate, low speed ride in the use of the process Gradually improved.

In addition to the above mentioned gearbox optimization, the vehicle ride comfort is also related to the engine. The torque response speed of the engine is also one of the factors that affect the driving experience.

At the same time, the powertrain mounting design also has a certain impact on the driver's perceived ride comfort.
