Driving moment coordinated control system and method of distributed-driving electric automobile

Abstract

The invention relates to a driving moment coordinated control system and method of a distributed-driving electric automobile. The system comprises a speed sensor, a steering wheel rotation angle sensor, an acceleration pedal sensor, a distributed-driving motor driving moment sensor, a distributed-driving electric automobile running state monitoring system, a distributed-driving electric automobile entire driving moment allocation controller, a distributed-driving motor, and an invalid driving moment coordinated control system which comprises a driver intension identifier, an invalid mode judger and a driving moment regulator, wherein the distributed-driving electric automobile running state monitoring system sends a speed signal and a steering wheel rotation angle signal to the driver intension identifier, and sends a feedback driving moment signal of each driving motor to the invalid mode judger; and the driving moment regulator coordinates and re-allocates the driving moment of each driving wheel according to the invalid state. The system and method provided by the invention can be widely applied to the cooperative control of the driving moment of the distributed-driving electric automobile.

Description

technical field [0001] The invention relates to a driving torque adjustment control system and method, in particular to a driving torque coordination control system and method suitable for distributed driving electric vehicles under failure conditions. Background technique [0002] At present, the automobile industry has become the leading industry of my country's modern equipment manufacturing industry and an important pillar of the national economy. However, the rapid growth of car ownership has made my country's energy shortage, environmental pollution and traffic safety issues increasingly prominent. Electric vehicles are an important direction for future development, and they can effectively solve the above problems. [0003] According to the different installation positions of the driving wheels, electric vehicles are divided into centralized drive electric vehicles and distributed drive electric vehicles. Different from centralized drive electric vehicles, distributed...

AI Technical Summary

Problems solved by technology

[0004] Distributed drive electric vehicles have four driving wheels. In the event that one or several driving wheels fail and cannot drive, accidents are prone to occur.

In order to avoid the occurrence of accidents, the way of direct parking is generally adopted, but this way does not make full use of other driving wheels that have not failed.
