  • Patent number: 8028375
    Abstract: A slide door is provided to be movable between a closed position to cover a side opening formed at a vehicle-body side face and an open position. The slide door is configured to move outward and subsequently slide rearward along a rear vehicle-body outer face when the slide door moves from the closed position to the open position. There is provided a detection sensor to detect a foreign matter in coming into a gap from a vehicle-compartment inside. A drive of the slide door is stopped in case the detection sensor detects the foreign matter in coming into the gap when the slide door moves toward the open position. Thereby, any foreign matter can be prevented from being pinched in the gap formed between the slide door and the rear edge portion of the side opening.

  • Publication number: 20090129105
    Abstract: A vehicle is equipped with a slide door, a seat provided near an ingress-egress opening, and an ingress-action detector to detect a passenger's ingress action through the ingress-egress opening. The vehicle is further equipped with an illumination device which comprises lower illuminators which are configured to illuminate lower areas which are located below a beltline of the vehicle such that a passenger's upper body is not illuminated, vehicle-inside upper illuminators which are configured to illuminate an upper-specified area in the vehicle compartment which is located above the beltline, and an illumination controller to control the illuminators. When the ingress action is detected by the ingress-action detector, the illumination controller prohibits the illuminations of the illuminators and starts the illuminations of the illuminators.
