The invention discloses an automobile electric retarder control method and an automobile electric retarder control system, and belongs to the technical field of automobile speed reducers. The system for implementing the method comprises a control system, the control system comprises a control switch, an electronic control unit, a driving relay, a power switch, an indicating lamp, a vehicle speed sensor, a temperature sensor, a test plug-in, a CAN interface, a brake lamp relay, a whole vehicle interface and a connecting wire harness. According to the invention, when the control switch is in a certain gear for a long time, the electronic control unit can calculate the working time of each coil of the retarder, and when the working time of a certain group of coils is detected to exceed the set time, the working group of the driving relay is automatically switched, and the switching of the working group follows the principles of rightward circulation and first-in first-out, and is completed within 1ms; a vehicle does not feel any feeling, overheating damage to a certain set of coils of the retarder due to long-time work is avoided, the service life of the retarder is prolonged, and theuse effect of the retarder is improved.
本发明公开了一种汽车电缓速器控制方法和系统,属于汽车减速器技术领域,实施该方法的系统包括控制系统,控制系统包括控制开关、电子控制单元、驱动继电器、电源开关、指示灯、车速传感器、温度传感器、测试插件、CAN接口、刹车灯继电器、整车接口和连接线束。本发明中,当控制开关长时间处在某档位时,电子控制单元能够计算缓速器各线圈的工作时间,当检测到某组线圈工作时间超过设定时间时,自动切换驱动继电器的工作组,切换工作组也是遵循“向右循环”、“先进先出”原则,切换在1ms时间内完成,车辆不会有任何感觉,避免缓速器某组线圈因长时间工作而过热损坏,提高缓速器的寿命和使用效果。
