Abstract

The embodiment of the invention provides an anti-lock control method and system of a vehicle and an electric vehicle, and belongs to the technical field of vehicle automatic control. The method specifically comprises the steps of collecting state information of a vehicle; determining the current slip rate of the electric driving wheel of the vehicle according to the state information and a slip rate model; under the condition that the current slip rate is larger than or equal to a preset slip rate threshold value, determining the target wheel speed of the motor driving wheel according to the state information and a slip rate model; and regulating the wheel speed of the motor driving wheel to the target wheel speed, so that the slip rate of the motor driving wheel is reduced to be smaller than a preset slip rate threshold value. According to the scheme, the wheel speed of the motor driving wheel is adjusted to the target wheel speed, the slip rate of the motor driving wheel can be reduced to be smaller than the preset slip rate threshold value; therefore, it is ensured that the slip rate in the braking process is within the safety range, and the braking anti-lock safety is provided.

Description

technical field [0001] The present application relates to the technical field of vehicle automatic control, in particular to a vehicle anti-lock brake control method, system and electric vehicle. Background technique [0002] With the continuous development of vehicle technology, in order to ensure driving safety, vehicles are generally equipped with anti-lock braking systems. The existing standard anti-lock braking system adjusts the pressure applied to the brake pads through the hydraulic circuit, and then realizes the adjustment of the braking force, and maintains the degree of slippage of the wheels through the control of the braking force. The existing electronic anti-lock braking system is equipped with motor wheels, which can directly control the current to realize the adjustment of the braking force, without the need to install hydraulic control hardware and algorithms. Although the related anti-lock braking system has been provided in the prior art, there is still ...
