The invention discloses a vehicle forced dormancy control method. The method comprises the following steps of: dividing vehicle functions into an off-vehicle function and a non-off-vehicle function, and dividing a vehicle-mounted ECU (Electronic Control Unit) into a first ECU, a second ECU and a third ECU according to the off-vehicle function and the non-off-vehicle function; the first ECU corresponding to the non-off-vehicle function, the second ECU corresponding to the off-vehicle function and the non-off-vehicle function, and the third ECU corresponding to the off-vehicle function; when it is recognized that the whole vehicle is powered off and a whole vehicle fortification signal is received, enabling the first ECU and the second ECU to respectively forbid corresponding non-off-vehicle function, so that the whole vehicle bus network is dormant; after the first ECU and the second ECU are awakened by the abnormal operation, enabling the first ECU and the second ECU continue to forbid the corresponding non-off-vehicle function according to the whole vehicle fortification signal and do not to actively send a request for awakening the whole vehicle bus network. By executing the vehicle forced dormancy control method, the energy consumption of a storage battery is reduced, the risk of power shortage of the whole vehicle is reduced, false triggering of the non-off-vehicle function is avoided, and the vehicle using experience of a user is improved.
本发明公开了一种车辆强制休眠控制方法,包括:将车辆功能划分为离车功能和非离车功能,并根据离车功能和非离车功能将车载ECU划分为第一ECU、第二ECU和第三ECU;第一ECU与非离车功能对应,第二ECU分别与离车功能和非离车功能对应,第三ECU与离车功能对应;在识别到整车下电且接收到整车设防信号时,第一ECU和第二ECU分别禁用对应的非离车功能,以使整车总线网络休眠;在被异常操作唤醒后,第一ECU和第二ECU根据整车设防信号,分别继续禁用对应的非离车功能,以及不主动发出唤醒整车总线网络的请求。通过执行本发明的车辆强制休眠控制方法,有利于降低蓄电池能量消耗,同时降低整车亏电的风险,还避免非离车功能的误触发,提高了用户用车体验。
