The invention discloses a method and a device for monitoring required torque of a hybrid electric vehicle, which are used for monitoring whether the required torque calculated by a required torque calculation module is correct or not, and proposing to calculate a required torque safety limit value at a monitoring layer with a higher safety level, and when the required torque calculated by the required torque calculation module exceeds the limit value, the required torque safety limit value is calculated. If the required torque calculated by the required torque calculation module still exceeds a limit value after resetting, the whole vehicle is controlled to be powered off emergently, so that unexpected movement, reverse movement, unexpected acceleration and the like of the hybrid electric vehicle are avoided, and the service life of the hybrid electric vehicle is prolonged. Therefore, the vehicle collides with people outside the vehicle or other vehicles, and casualties of people inside and outside the vehicle are caused.
本发明公开了一种混合动力汽车需求扭矩监控方法及装置,为监控需求扭矩计算模块计算的需求扭矩是否正确,提出在安全等级更高的监控层计算需求扭矩安全限值,当需求扭矩计算模块计算的需求扭矩超出限值时,认为需求扭矩计算模块计算错误,对该模块进行重置,若重置后需求扭矩计算模块计算的需求扭矩仍然超出限值,则控制整车紧急下电,避免混合动力汽车非预期移动、移动反向、非预期加速等,从而造成该车辆与车辆外部人员或其他车辆发生碰撞,导致车辆内外部人员伤亡的严重事故。
