In the present embodiment, the occupant pushes the continue button displayed on the screen of the touch panel display 28 to input the continue command to the control device 5.

When the continuation command is input (Yes in S8), the control device 5 resets the timer count (S9) and restarts the timer count (S10). That is, the control device 5 measures the time from when the continuation command is input.

Following the processing of step S10, the control device 5 determines whether or not the occupant is seated on the seat 3 provided with the electrical equipment 4 based on the signal from the occupant detection means 7 (S11). When it is determined that the occupant is seated in the seat 3 (Yes in S11), the control device 5 resets the timer count (S12), and executes the electrical device operation control again from step S1. As a result, the electrical equipment 4 is maintained in an operating state.

When it is determined in step S11 that the occupant is not seated in the seat 3 (No in S11), the control device 5 determines whether the timer count T has reached a predetermined period T1 (S13). That is, in step S13, the control device 5 determines whether or not the time during which the occupant is not seated in the seat 3 has reached the period T1 after the continuation command is input. When the control device 5 determines that the timer count T has not reached the period T1 (No in S13), the control device 5 performs the determination in step S11 again. When determining that the timer count has reached the period T1 (Yes in S13), the control device 5 resets the timer count (S14) and performs the process of step S3 again.

When the controller 5 determines that the continuation command is not input in step S8 (No in S8), the controller 5 determines whether the timer count T has reached the predetermined period T2 (S15). That is, the control device 5 determines in step S15 whether or not the time from when the alerting means 6 has issued the alert has reached the period T2. When it is determined that the timer count T has not reached the period T2 (No in S15), the control device 5 performs the determination in step S5 again. When the control device 5 determines that the timer count has reached the period T2 (Yes in S15), the control device 5 stops the electrical device 4 (S16). After completing the process of step S16, the control device 5 resets the timer count (S17), and then executes the electrical device operation control again from step S1.
