The invention relates to a power module fault diagnosis and processing method and system, a vehicle and electronic equipment. The power module fault diagnosis and processing method comprises the following steps: when a power module fault is monitored, identifying whether DCDC jumps within a preset time before the fault, if not, executing the following steps: performing reset judgment according to a fault type, reporting a fault recoverable flag bit if the condition is met, and reporting a fault unrecoverable flag bit if the condition is not met; executing resetting according to the reported flag bit and the working mode of the motor system; if yes, timing is started from the time when the fault is recognized, the DCDC output power when the DCDC jumps is recognized, the pull-down time is determined, the reset time and the response time are combined, the reset delay time is determined, and the reset operation is executed. The invention further provides a system of the power module fault diagnosis and processing method. The invention further provides electronic equipment and a vehicle. According to the invention, the power interruption risk of the electric vehicle caused by false alarm of the power module fault is reduced.
本发明涉及功率模块故障的诊断及处理方法、系统、车辆及电子设备。功率模块故障的诊断及处理方法,包括:当监测到功率模块故障时,识别故障前预设时间内的DCDC是否跳变,若否,则执行:以故障类型进行复位判断,满足条件上报故障可恢复标志位,不满足条件则上报故障不可恢复标志位;根据上报标志位和电机系统工作模式执行复位;若是,则执行:从识别到故障开始计时,识别DCDC出现跳变时的DCDC输出功率,以确定拉低时间,结合复位时间和响应时间,确定复位延迟时间,执行复位操作。本发明还提供功率模块故障的诊断及处理方法的系统。本发明还提供一种电子设备和车辆。本发明降低了因功率模块故障误报导致的电动汽车动力中断风险。
