Antiskid control system and method for electromobile

Abstract

The present invention discloses one kind of antiskid control system for electromobile. The antiskid control system includes wheel speed sensors for detecting the real-time speeds of the wheels, wheel brakes for braking the wheels separately, one motor for driving the electromobile, and one ABS / ASR integrated control unit connected to all the sensors, the brakes and the motor. When it receives an acceleration signal, the ABS / ASR integrated control unit regulates the real-time output torque of the motor based on the wheel slip rate; and when it receives a braking signal, it regulates the real-time braking force based on the wheel slip rate. The present invention can reduce the slip rate of electromobile effectively and raise its running stability.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an anti-skid control system of the electric vehicle. Background technique [0002] At present, ABS and ASR have gradually become standard configurations on automobiles. The common goal of ABS and ASR is to limit the wheel slip rate within a certain acceptable range to ensure good driving performance of the vehicle. ABS (Anti-lock Braking System) is the anti-lock braking system of automobiles. It mainly controls and adjusts the pressure of the brake line to prevent the dangerous working conditions of the wheels from locking during the braking process of the vehicle, which can improve the handling performance of the vehicle. ; ASR (Anti-Slip Regulation) is a car drive anti-skid system, by adjusting the power output of the vehicle, making full use of the road adhesion rate, to achieve the effect of enhancing driving ability and handling stability. ASR usually has three control meth...
