The invention discloses a control method and device for an electronic limited slip differential. The method comprises the steps that it is determined that the vehicle speed, the steering wheel angle and an ABS meet a first condition; during starting, if the opening change rate of an accelerator pedal is larger than an opening change rate threshold value, the output value of the feedforward control module is determined; when the vehicle is accelerated to run on a separated road surface, an output value of the traction force control module is determined according to an actual wheel speed difference and a target wheel speed difference of the left and right rear wheels; an output value of the stability control module is determined upon excessive steering. The method has the beneficial effect that the driving stability and the driving safety of the vehicle are improved.

    本发明公开了一种电子限滑差速器的控制方法、装置,方法包括:确定车速、方向盘角度和ABS满足第一条件;在起步时,若油门踏板开度变化率大于开度变化率阈值,确定所述前馈控制模块的输出值;在加速行驶于分离路面时,根据左右两个后轮的实际轮速差和目标轮速差,确定所述牵引力控制模块的输出值;在转向过度时,确定所述稳定性控制模块的输出值。有益效果:提高车辆的行驶稳定性和驾驶安全性。
