Abstract: If closing operation to the passenger's seat sub switch continues for not less than a prescribed time period Tb, a passenger's seat relay contact on a close side is turned ON. If the closing operation to the passenger's seat sub switch thereafter ends before a prescribed time period Tc elapses, the passenger's seat relay contact on the close side is kept ON. If opening operation to the passenger's seat sub switch continues for not less than the prescribed time period Tb, a passenger's seat relay contact on an open side is turned ON. If the opening operation to the passenger's seat sub switch thereafter ends before the prescribed time period Tc elapses, the passenger's seat relay contact on the open side is kept ON. The invention is applicable to an automatic window system and the like.

Abstract: The invention improves detection accuracy of interposition at a vehicle window. An interposition detector determines that a window at a passenger's seat has interposition if motor current for opening and closing the window at the passenger's seat does not decrease to be less than a predetermined threshold but increases to be not less than a second threshold, or if the motor current does not decreases to be less than the predetermined threshold but increases at a predetermined or more increase rate. The interposition detector determines that the window at the passenger's seat does not have interposition if the motor current is less than the predetermine threshold. The invention is applicable to an automatic window system and the like.

Abstract: In a headlamp luminance controlling device, a CPU 21 first decides a luminance factor D based on a state of each switch 10 to switch 12 and a signal from a sensor 13. The CPU 21 determines an initial value of a PWM duty ratio S from the luminance factor D with a load current Ap as a default value (rated current A0). The CPU 21 starts the initial driving of a headlamp HL using the duty ratio S. The CPU 21 then determines the luminance factor D based on the state of each switch 10 to switch 12 and the signal from the sensor 13. Next, the CPU 21 determines the PWM duty ratio S based on the luminance factor D and the load current Ap detected by the headlamp current detector 23. The CPU 21 drives the headlamp HL using the PWM duty ratio S.
