The invention discloses a vehicle control method, a master controller, slave controllers and a vehicle control system. The master controller and at least one slave controller are arranged in the vehicle. The method comprises the steps that under the condition that it is recognized that a vehicle door is unlocked or opened, the main controller detects an ignition signal of the vehicle; and if the ignition signal is not detected, the master controller sends a wake-up request message to the slave controller, so that the slave controller enters a wake-up state after receiving the wake-up request message. According to the method, before a vehicle is ignited and started, a master controller sends an awakening request message to slave controllers in advance so as to at least awaken part of the slave controllers, so that the awakened slave controllers can monitor the state of the vehicle in advance, and therefore the vehicle can have sufficient time to monitor the state of the whole vehicle before being started; the starting preparation is made, so that the starting performance and safety of the vehicle are improved.

    本发明公开了一种车辆的控制方法、主控制器、从控制器及车辆的控制系统,车辆中设置有主控制器和至少一个从控制器;所述方法包括:在识别到车门被解锁或打开的情况下,所述主控制器对所述车辆的点火信号进行检测;若未检测到所述点火信号,所述主控制器向所述从控制器发送唤醒请求报文,以使所述从控制器在接收到所述唤醒请求报文后进入唤醒状态。该方法中的主控制器在车辆点火启动前,预先向从控制器发送唤醒请求报文,以至少唤醒部分从控制器,使得唤醒后的从控制器能够预先对车辆的状态进行监控,从而使得车辆在启动前能够有充足时间对整车状态进行监控,并做好启动准备,进而提升了车辆的启动性能和安全。
