Abstract

The invention discloses a vehicle control method and further provides a vehicle control system for achieving the vehicle control method. The vehicle control method comprises the steps that the current opening degree of an accelerator pedal and the vehicle speed are obtained, and according to the opening degree of the accelerator pedal and the vehicle speed, the target torque is obtained; according to the current motor rotary speed, motor state and battery state, the driving torque limiting value and the feedback torque limiting value are obtained; and the target torque is corrected into the output torque according with the driving torque limiting value and the feedback torque limiting value, and output torque output is controlled. According to the vehicle control method, the current opening degree of the accelerator pedal and the vehicle speed are obtained, the action intention of a driver is analyzed and obtained to obtain the target torque of driver operation, and the target torque is corrected through the driving torque limiting value and the feedback torque limiting value to obtain the output torque, and the output torque is output; and feedback can be achieved on the practical operating intention of the driver, and the driving feeling of the driver is good.

Description

technical field [0001] The present invention relates to the technical field of vehicle control, and more specifically, relates to a vehicle control method. In addition, the present invention also relates to a vehicle control system for realizing the above vehicle control method. Background technique [0002] In the current vehicle control device, the vehicle controller is the core component of the new energy vehicle, which can coordinate and control the vehicle power system and comprehensively manage the entire electric drive system. [0003] As the core component of the electric vehicle, the vehicle controller comprehensively manages the vehicle power system. The vehicle control strategy affects the function and performance of the vehicle. However, in the existing vehicle controllers, there is the problem of unreasonable use of electric vehicle feedback braking, poor feedback adjustment performance for the vehicle, and the feedback cannot be realized for the driver's actu...
