The invention provides a dormancy and awakening control method for an electric booster, which comprises the following steps: the electric booster is in signal connection with a vehicle body controller through a CAN (Controller Area Network) bus and is in signal connection with an ignition switch through a hard wire, and the electric booster receives a CAN bus ignition signal and a hard wire ignition signal. And when any one of the CAN bus ignition signal and the hard wire ignition signal is in an ignition state, it is considered that the vehicle is in an ignition state, and the electric booster keeps a normal brake boosting function. And if the hard wire ignition signal is inconsistent with the ignition state of the CAN bus, the electric booster keeps a normal boosting function, and meanwhile, a fault code of inconsistent ignition signals is reported. And if the hard wire ignition signal and the CAN bus ignition signal both show that the vehicle is in a power-off state, the electric booster enters a power-off sleep mode. The use comfort and convenience of a user can be improved, and the use safety of the vehicle is improved.
本发明提供一种电动助力器的休眠和唤醒控制方法,包括:电动助力器通过CAN总线与车身控制器信号连接,并通过硬线与点火开关信号连接,电动助力器接收CAN总线点火信号和硬线点火信号。当CAN总线点火信号和硬线点火信号任意一个信号处于点火状态时,则认为车辆处于点火状态,电动助力器保持正常的制动助力功能。如果硬线点火信号和CAN总线点火状态不一致,则电动助力器保持正常助力功能,同时上报点火信号不一致故障码。如果硬线点火信号和CAN总线点火信号均显示车辆处于下电状态,则电动助力器进入下电休眠模式。本发明能增加用户使用的舒适感和便捷性,提高车辆使用的安全性。
