The invention discloses an automatic control method of an automobile differential lock. The automatic control method comprises an automatic opening method of the automobile differential lock and an automatic closing method of the automobile differential lock. According to the automatic control method of the automobile differential lock, the automatic opening and closing functions of the automobiledifferential lock are achieved through control of the VCU controller, so that the automobile differential lock function can be accurately opened and closed in time, the automobile can normally and safely run, and the driving safety and performance of the automobile are guaranteed. According to the method, the vehicle speed of the ABS system is compared with the theoretical vehicle speed calculated by the TCU controller, and complementary replacement is adopted, so that the vehicle speed used in differential lock control is more accurate and closer to the vehicle speed of a real vehicle, the differential lock control precision is higher, the safety performance is better, the automatic opening and closing functions of the differential lock can be accurate, and the driving safety of the vehicle is guaranteed.
本发明公开了一种汽车差速锁的自动控制方法,包括:汽车差速锁的自动开启方法和汽车差速锁的自动关闭方法。本发明汽车差速锁的自动控制方法,通过VCU控制器控制,实现汽车差速锁的自动开启和关闭功能,使得车辆能够及时准确的开启和关闭汽车差速锁功能,使得车辆能够正常安全运行,保证车辆的行车安全和性能。本方法通过比较ABS系统的车速和TCU控制器计算出的理论车速,互补替代,使得在差速锁控制中使用的车速更精确,更接近于实车车速,使得差速锁控制精度更高,安全性能更好,使得差速锁的自动开启和关闭功能能精确和准确,保证车辆的行车安全。
