Abstract

PURPOSE: To alarm only the approaching of an object, which really requires attension by obtaining a detection area of the approaching object by empoloying the signals from car speed sensor and steering angle sensor, thereby deciding whether there is such an object in said area and functioning an alarm means if any.
CONSTITUTION: When the car 1 shown by solid line OCPQ moves in the direction of steering angle θ at speed V, the object detection area at V=O is shown by OABC while the position of detection area after elapsing time to is shown by O'A'DC. The detection area as of the car is in the position of solid line is approximately shown by OADE, thereby when previously providing the area at V=O the area OADE can be obtained and the existence of an object in said region is detected to produce an alarm. In other word the outputs from an object detector 3, can speed sensor 4 and steering angle sensor 5 are sent to the controller 2 where said calculation is performed. Thereafter the command signal for detection operation is produced in accordance with the operation of direction indicating sensor 6 to function the indicator 7 and the alarm 8.
