Control method and device for start motor

Abstract

The invention discloses a control method and device for a start motor. The control method includes the steps that when a power assembly controller detects that a transmission controller generates a start command, whether an engine is operated or not is detected through the power assembly controller, wherein the start command is used for indicating the start motor to start working; if it is detected that the engine is operated, the start motor is controlled to be in an idle state by a first relay connected in a circuit of the start motor in series. By the adoption of the control method and device, the problem that the driving stability of a whole automobile is affected due to the mistaken start of the start motor in the prior art is solved, and the situation that the start motor interferes in the operation process of the engine due to mistaken operation is effectively prevented.
本发明公开了一种启动电机的控制方法和设备。其中,该控制方法包括:当动力总成控制器检测到变速箱控制器生成启动指令时,通过动力总成控制器检测发动机是否正在运转,其中,上述启动指令用于指示启动电机开始工作;若检测到上述发动机正在运转,则通过串联在启动电机回路中的第一继电器控制上述启动电机处于空闲状态。采用本发明,解决了现有技术中的因启动电机误启动而影响整车行驶稳定的问题,实现了有效防止发动机运行过程中因误操作而引起的启动电机介入的效果。
