A gearbox power-on and power-off control method, device and equipment and a readable storage medium, the gearbox power-on and power-off control method comprises the following steps: when a motor or gearbox fault is detected in the power-on process of a vehicle gearbox, if the power-on duration of the gearbox is less than a first preset duration and the fault does not disappear after the fault occurs for a second preset duration, the power-on duration of the gearbox does not disappear; if yes, reporting a fault; when it is detected that a communication fault occurs between a gearbox controller and a motor controller in the power-off process of the vehicle gearbox, if the motor rotating speed obtained at the last time is higher than the preset rotating speed, the current motor rotating speed is estimated based on the motor rotating speed obtained at the last time and the preset descent rate; and if the current rotating speed of the motor is lower than the preset rotating speed, the current vehicle speed is lower than the preset vehicle speed, and the motor completes active discharging, the gearbox controller executes the power-off process after the dormancy signal is received for a third preset duration. According to the invention, the experience in the power-on process of the vehicle can be improved, and the safety in the power-off process of the vehicle can be improved.

    一种变速箱上下电控制方法、装置、设备及可读存储介质,变速箱上下电控制方法包括:当车辆变速箱在上电过程中检测到电机或者变速箱故障时,若变速箱的上电时长小于第一预设时长,且在故障发生第二预设时长后故障未消失,则上报故障;当车辆变速箱在下电过程中检测到变速箱控制器与电机控制器之间发生通讯故障时,若最后一次获取到的电机转速高于预设转速,则基于最后一次获取到的电机转速和预设下降速率估算当前电机转速;若当前电机转速低于预设转速,且当前车速小于预设车速,且电机已完成主动放电,则在接收到休眠信号第三预设时长后,变速箱控制器执行下电流程。通过本申请,能够提升车辆上电过程中的体验,提升车辆下电过程中的安全性。
