The invention provides a heavy AMT commercial vehicle rapid starting control method and system and method, and belongs to the technical field of vehicle starting control. The method comprises the following steps that after a vehicle controller detects that a vehicle is engaged with a starting gear, a brake loosening signal is detected in real time; after a brake loosening signal is detected, the vehicle control unit collects the temperature of a clutch and judges whether the temperature of the clutch meets a set pre-starting condition or not; if yes, the vehicle is controlled to enter a pre-starting mode, the vehicle is controlled to enter an idling state, and a clutch is controlled to be pre-combined to wait for an accelerator signal; if not, the vehicle is controlled to enter a protection mode, and the starting state is controlled according to the accelerator signal and the clutch temperature. The clutch is combined in advance in the pre-starting mode, the starting delay time is shortened, the problem of slow starting is solved, slope sliding during uphill starting is avoided, vehicle safety is guaranteed, meanwhile, the temperature of the clutch is monitored, high-temperature alarm and early warning of the clutch are achieved, and the service life of the clutch is prolonged.
本发明提供一种重型AMT商用车快速起步控制方法及系统及方法,属于车辆起步控制技术领域,所述方法包括如下步骤:整车控制器检测到车辆挂起步挡后,实时检测刹车松开信号;当检测到刹车松开信号后,整车控制器采集离合器温度,判断离合器温度是否满足设定预起步条件;若满足则控制车辆进入预起步模式,控制车辆进入怠速状态,并控制离合器进行预结合来等待油门信号;若不满足,控制车辆进入保护模式,根据油门信号及离合器温度控制起步状态。本发明通过在预起步模式提前结合离合器,缩短了起步延迟时间,解决了起步慢的问题,并避免上坡的起步溜坡,保障车辆安全,同时对离合器温度的监控,实现离合器高温报警、预警,提高离合器的使用寿命。
