The invention relates to a control method of a power-assisted steering system. The control method comprises the following steps: acquiring an ignition switch state, an idling start-stop state and an engine state; when the state of the ignition switch is ON and the idle speed start-stop state is in a start-stop standby state or in an automatic start state or in an automatic stop state or in an automatic operation state, the power-assisted steering control mode is switched to a start-stop power-assisted mode; and when the state of the ignition switch is ON and the idle speed start-stop state is that the automatic start-stop is closed or the automatic start-stop is unavailable, the power-assisted steering control mode is switched to the conventional power-assisted mode. The invention further provides a control device. The invention further provides a storage medium. The invention further provides a vehicle. The system has the following characteristics that power-assisted steering can be provided during the idle-speed automatic stop period; under the working condition that a driver actively stops, steering assistance is not provided; and a start-stop power-assisted control strategy is reasonably set, so that the dependence on the electric quantity of a vehicle storage battery can be reduced while the steering power-assisted requirement in the idling automatic stop period is met.

    本发明涉及一种转向助力系统控制方法,包括以下步骤:获取点火开关状态、怠速启停状态和发动机状态;当点火开关状态为ON,怠速启停状态为启停待机中或自动启动中时或自动停机中或自动运行中时,将转向助力控制模式切换至启停助力模式;当点火开关状态为ON,怠速启停状态为自动启停关闭或自动启停不可用时,将转向助力控制模式切换至常规助力模式。本发明还提出了一种控制装置。本发明还提出了一种存储介质。本发明还提出了一种车辆。本发明具有以下特点:在怠速自动停机期间可以提供转向助力;在驾驶者主动停机工况下,不提供转向助力;合理设置启停助力控制策略,在满足怠速自动停机期间的转向助力需求的同时能够降低对车辆蓄电池电量的依赖。
