The invention relates to the technical field of vehicle control, in particular to a manual switch monitoring method and a new energy vehicle. The method comprises the steps that under the condition that the new energy vehicle is in a high-voltage state, real-time voltage between a low-voltage storage battery and a manual switch is obtained, and the low-voltage storage battery is electrically connected with the manual switch; under the condition that the real-time voltage is smaller than a preset voltage threshold value, driver seat use information is obtained; under the condition that the driver seat use information indicates that the driver seat is used by a person, switch accidental disconnection prompt information is generated, and the switch accidental disconnection prompt information is used for prompting that a manual switch is disconnected accidentally; and under the condition that the driver seat use information indicates that the driver seat is not used by a person, manual switch-off prompt information is generated, and the manual switch-off prompt information is used for prompting manual switch-off. The defect that high-voltage electric shock potential safety hazards exist in the maintenance process due to the fact that a manual switch is switched off in the prior art is overcome.
本发明涉及车辆控制技术领域,尤其涉及一种手动开关监测方法及新能源车。该方法包括:在新能源车处于上高压状态的情况下,获取低压蓄电池与手动开关之间的实时电压,其中,低压蓄电池与手动开关电连接;在实时电压小于预设电压阈值的情况下,获取驾驶座使用信息;在驾驶座使用信息指示驾驶座有人使用的情况下,生成开关意外断开提示信息,其中,开关意外断开提示信息用于提示手动开关意外断开;在驾驶座使用信息指示驾驶座无人使用的情况下,生成开关人为断开提示信息,其中,开关人为断开提示信息用于提示手动开关人为断开。本发明用以解决现有技术中手动开关断开导致检修过程存在高压触电安全隐患的缺陷。
