Oil pump control method, vehicle and medium

The oil pump control method comprises the steps that whether a control signal sent by a controller is received or not is judged, the control signal is used for indicating the rotating speed of an oil pump, and the oil pump is used for lubricating and/or cooling a motor; if the control signal is received, operation is carried out based on the rotating speed indicated by the control signal; and if the control signal is not received, running at a fixed rotating speed. By means of the method, the situation that the oil pump stops running due to signal loss is avoided, and safe and reliable running of the vehicle is effectively guaranteed. 本申请实施例提供的油泵控制方法，包括：判断是否接收到控制器发送的控制信号，所述控制信号用于指示油泵的转速，所述油泵用于电机的润滑和/或冷却；若接收到所述控制信号，则基于所述控制信号所指示的转速进行运转；若未接收到所述控制信号，则以固定转速进行运转。通过该方法避免了由于信号丢失而导致的油泵停止运转，有效保证了车辆的安全和可靠运行。
