The invention provides a control method, a chassis domain control system and a timely four-wheel drive type automobile. The control method comprises steps of receiving an accelerator opening degree detected by an accelerator opening degree sensor; receiving a first speed signal, detected by a wheel speed sensor, of a first driving wheel of the timely four-wheel drive type automobile; acquiring a slip rate of the first driving wheel based on the first speed signal; identifying a starting state of the timely four-wheel drive type automobile based on the accelerator opening degree; and determining whether to trigger a 4WD electric control unit and/or a TCS electric control unit based on the starting state and the slip rate of the first driving wheel. Compared with the prior art, the trigger sequence of the 4WD electric control unit and the TCS electric control unit can be adjusted, so the trigger sequence of the 4WD electric control unit and the TCS electric control unit can meet expectation of a driver for automobile starting, and use experience of the driver is improved.

    本申请提供一种控制方法、底盘域控制系统及适时四轮驱动式汽车,包括:接收所述油门开度传感器检测到的油门开度;接收所述轮速传感器检测的所述适时四轮驱动式汽车的第一驱动轮的第一速度信号;基于所述第一速度信号获取所述第一驱动轮的滑转率;基于所述油门开度识别所述适时四轮驱动式汽车的起步状态;基于所述起步状态以及所述第一驱动轮的滑转率确定是否触发所述4WD电控单元和/或所述TCS电控单元。与现有技术相比,能够调节4WD电控单元和TCS电控单元触发顺序,使得4WD电控单元和TCS电控单元触发顺序能够满足驾驶员对于汽车起步的期望,提高了驾驶员的使用体验。
