The invention discloses an automatic control method and device for locking a power-off parking gear of a pure electric vehicle, and the method comprises the steps that: vehicle power supply information is collected, and the analysis is carried out based on the vehicle power supply information to obtain the power-off intention information of a driver; when it is determined that the power-off intention information of the driver represents the power-off tendency, vehicle operation information is obtained, and whether the vehicle meets a parking gear locking condition or not is judged according to the vehicle operation information; and when it is determined that the vehicle meets the parking gear locking condition, a locking control instruction is generated, and the locking control instruction is used for controlling the driving motor controller to switch the vehicle gear to the parking gear. The vehicle can be automatically controlled to be switched to the parking gear after it is determined that the vehicle is parked and powered off, the anti-theft safety of the pure electric vehicle is guaranteed, the gear of the vehicle after parking and powered off can be adjusted through setting when a driver needs, and then traction of the vehicle in a fault or dormant state can be conveniently achieved.
本发明公开了一种纯电动汽车下电停车挡锁定自动控制方法及装置,该方法包括采集车辆电源信息,基于车辆电源信息解析得到驾驶员下电意图信息;当确定驾驶员下电意图信息表征出下电倾向时,获取车辆运行信息,根据车辆运行信息判断车辆是否满足停车挡上锁条件;在确定车辆满足停车挡上锁条件时,生成上锁控制指令,上锁控制指令用以控制驱动电机控制器将车辆档位切换至停车挡。本发明实现了能够在确定车辆停车下电后自动控制车辆切换至停车挡,保证了纯电动汽车的防盗安全,且在驾驶员有需要时,能够通过设置来调整停车下电后的车辆挡位,进而能够方便实现车辆在故障或休眠状态下的牵引。
