And S1, detecting an acousto-optic prompt trigger signal.

In an embodiment, the audible and visual prompt trigger signal may be a sensor signal or an operation signal of the operation unit, for example, a status parameter of the vehicle, such as a door status, a cooling liquid amount, a fuel amount, a tire pressure, etc., is collected by a sensor, wherein if an abnormality, such as a door not closed, a coolant shortage, a fuel shortage, a tire pressure shortage, etc., is determined according to the vehicle status parameter, it is determined that the audible and visual prompt trigger signal is detected. For another example, the vehicle light control, the lighting lamp is turned on by the light switch, and when the operation signal for turning on the light is detected, the acousto-optic prompt control, such as the control of the instrument or the display screen prompt, and the control of the speaker buzzing prompt, is triggered.
