AMT gearbox, the must-have "equipment" for trucks to achieve automatic driving

According to Xiaobian, the event organizer will fully demonstrate the autonomous driving technology capability of commercial vehicles and the application potential under the future road coordination conditions, providing an efficient and feasible for the commercial field in a controlled environment in the future. A low cost solution. If the vehicle wants to achieve automatic driving, AMT (automatic transmission) configuration is an essential "equipment". Let's take a look at how the AMT gearbox shines in this automatic driving standard verification test. of.

Line-up test

Auman and ZF form an automatic driving CP

In this verification test, the Foton Cummins X-power and the ZF TraXon gearbox equipped with Auman EST form the CP in the field of automatic driving. The super-application of ZF's new-generation TraXon automatic transmission also achieved the minimum distance of 17.5m for the Auman EST of this test.

In the formation acceleration test scenario, the Auman super heavy truck accelerates from a standstill to 60 km/h and maintains a constant speed. The three test vehicles easily realize the line-up. After the formation, the minimum distance is only 17.5m, which fully meets the relevant technical standards. The required two distances are kept within the range of 20m ± 25%. Accelerating from a standstill to 60 km/h and maintaining a constant speed, the efficiency of the ZF TraXon gearbox is extremely high during this process, thanks to the ability of the TraXon to withstand up to 3,440 Nm and up to 99.7%. The transmission efficiency ratio provides the best specific power among the best.

In addition, the reporter learned that the basic gearbox combined with a torque converter lock-up clutch on the ZF TraXon gearbox also ensures wear-free start-up and mitigation even at extremely high input torques and low speeds. Comfortable maneuverability.

It is worth mentioning that in addition to the optimization of the shift strategy, the additional electronic control device brings some additional functions. For example, PreVision GPS, an advanced feature that predictably shifts terrain through GPS. It can be said that the many advantages of the ZF TraXon gearbox have become the key to the test of Foton Auman EST to complete the automatic driving acceleration process.

Dongfeng AMT gearbox automatic driving mode to understand?

As the other king of this test, Dongfeng Tianlong KL, it is naturally inseparable from a powerful AMT gearbox.

The Dongfeng 14-speed AMT gearbox is a domestically developed product with a maximum input torque of 2,800 Nm and a maximum power of 560 Kw. Its product features are reliable in quality, light in weight, comfortable in shifting, fuel-efficient and powerful, and can be matched with engines of higher power.

In addition, the gearbox automatically completes gear shifting based on optimal power and economy shifting rules. Eliminate differences in driving skills and provide better comfort. At the same time, through the action of the electronic control actuator, the vehicle handling performance is greatly improved, thus ensuring the successful completion of this standard verification by the Dongfeng Tianlong KL self-driving model.

The secret weapon of Judeka "automatic driving" - AMT gearbox

In terms of automatic acceleration driving, Shantou China National Heavy Duty Truck Deca also completed the excellent performance of this open test. This time, the team followed the test, the distance between the vehicles and the car was 15 meters ± 20%, and the speed was increased to 60km / h, once again demonstrating the leading position of China National Heavy Duty Truck in the field of intelligent networked commercial vehicles.

He has such outstanding performance in China's heavy-duty Huideka autopilot application, benefiting from the AMT gearbox developed by China National Heavy Duty Truck and WABCO. This product is provided by WABCO with control software and is composed of gearbox hardware designed by China National Heavy Duty Truck. At the same time, the reporter learned that the maximum input torque of the AMT gearbox of the Judeka is 2,500 Nm, which can cope with the maximum torque of 2,500 Nm of the MC13 engine.

In addition, the AMT gearbox has a helical gear design that provides higher efficiency, greater reliability and greater input torque than the straight gear design of a conventional gearbox. This time, China National Heavy Duty Truck Co., Ltd. has achieved excellent results in the automatic driving and speeding test, and its matching AMT gearbox is also indispensable.

With the successful completion of China's first heavy-duty trucks to verify the standard of commercial vehicles in China, it can be said that not only the domestic commercial vehicle automatic driving exploration, but also the application of unmanned driving technology in the commercial vehicle field has laid the foundation. Whether for autonomous driving or modern transportation, these three AMT gearboxes are designed to meet the requirements of fuel economy, reliability and comfort. In the future, the development trend of truck powertrains will gradually get rid of the complicated models and gearbox types that have been used in the past, and further develop towards electricization and automation. These three AMT products will become indispensable in the future autonomous driving power chain. "Equipment".
