Technical Field
The present disclosure relates to the field of vehicle-mounted electronic technologies, and in particular, to a method and an apparatus for detecting whether a switch in a vehicle is operating normally.

In the automotive industry, the assembled vehicle is electrically inspected before being taken off the production line. The method comprises the steps of detecting various switches on the whole vehicle to determine that the switches can work normally. In the related art, the detection of the switch is performed by manual operation.
Some switches can be operated manually, and whether the switches work normally or not is judged in a visual mode. However, although some other switches can be manually operated, it cannot be determined whether the switches can work normally by visual inspection. For example, a brake switch and a clutch switch are switches that cannot be visually checked to determine whether they are operating normally. When the detection personnel turns on or off the brake switch and the clutch switch, if the vehicle is not in a running state, the detection personnel can only see that the detection personnel turns on or off the brake switch and the clutch switch, but cannot see the reaction of the brake switch and the clutch switch to the turning-on or turning-off operation, so that whether the switches can normally work or not cannot be judged.

Alternatively, the preset operation includes an operation of turning on the target switch and an operation of turning off the target switch. After seeing the prompt information which is displayed on the display screen and used for prompting the inspector to carry out preset operation on the target switch of the target vehicle, the inspector can carry out the operation required on the display screen, such as stepping on the brake pedal switch and releasing the brake pedal switch.
