The invention provides a vehicle anti-slip system and method, and relates to the technical field of vehicles, and the system specifically comprises a state detection module which is used for detectinga vehicle to obtain a whole vehicle state signal; a control module which is used for receiving the anti-slip-off instruction, generating an anti-slip-off activation signal when the whole vehicle state signal meets the anti-slip-off activation condition and outputting the anti-slip-off activation signal; an electronic parking brake module which comprises a first processing unit used for recognizing a trapped wheel and an idle wheel according to a whole vehicle state signal, continuously outputting the wheel speed of the idle wheel and continuously calculating the single-wheel deceleration of the idle wheel according to the wheel speed; and a second processing unit which is used for controlling the execution module to dynamically adjust the wheel speed limit of the idle wheel according to the wheel speed and the corresponding single-wheel deceleration so as to realize slip prevention of the vehicle in a mode of increasing the torque of the trapped wheel. The beneficial effect is that the electronic parking brake module controls the execution module to dynamically adjust the wheel speed of the idle wheel so as to increase the torque of the trapped wheel to realize slip prevention ofthe vehicle.

    本发明提供一种车辆防滑脱困系统及方法,涉及车辆技术领域,具体包括:状态检测模块,用于检测车辆得到整车状态信号;控制模块,用于接收防滑脱困指令并在整车状态信号满足防滑脱困激活条件时生成一防滑脱困激活信号并输出;电子驻车制动模块,包括:第一处理单元,用于根据整车状态信号识别出被困轮和空转轮,持续输出空转轮的轮速,根据轮速持续计算得到空转轮的单轮减速度;第二处理单元,用于根据轮速及对应的单轮减速度控制执行模块动态调整对空转轮的轮速限制,以通过增大被困轮的扭矩的方式实现车辆防滑脱困。有益效果是通过电子驻车制动模块控制执行模块动态调整空转轮的轮速进而增大被困轮的扭矩实现车辆防滑脱困。
