Abstract
PURPOSE:To prevent the wrong indication within a predetermined nearby dead zone, by providing a vehicle obstacle indicator which employs ultrasonic waves or the like and includes a holding means for detecting the presence of an obstacle within a prescribed distance corresponding to the nearby dead zone and for indicating the distance. CONSTITUTION:An ultrasonic wave transmitter 1 and an ultrasonic wave receiver 3 are mounted on the rear of a vehicle 14. The border between a detectable zone A and a dead zone B is 0.5m away from the rear of the vehicle 14. When the vehicle has approached an obstacle so that it is located in the detectable zone A, the obstacle is detected through a time measuring section 5 and a distance judgment section 6 and the distance to the obstacle is indicated on a display section 7. When the vehicle has more approached the obstacle so that it is located in the dead zone B, the obstacle is detected through a dead zone distance judgment section 9 and a holding section 10 and all the lights of the display section 7 are turned on. When the vehicle 14 is thereafter moved forth by 0.5m or more, it is found out through a hold stoppage signal generation section 13 on the basis of the output signals of a moving direction detector 11 and a moving distance detector 12 that the vehicle is moved by 0.5m or more away from the obstacle. At that time, a hold stoppage signal is applied to the holding section 10 to stop holding.
