PURPOSE:To generate a proper control signal for prevention against a collision by calculating the predicted drive track of an automobile and deciding on the extent of interference between an obstacle which disturbs the smooth run of the automobile and said drive track. CONSTITUTION:An obstacle detector 10 is arranged at the periphery of the automobile and decides on the position relation between the automobile and the obstacle. A steering angle detector 20 generates an electric angle correspond ing to the angle of steering. An onward direction detector 30 decides on the rotating direction of wheels when the automobile moves. A drive area calculat ing part 41 calculates the predicted drive track of the automobile by using signals from the steering angle detector 20 and onward direction detector 30. A collision decision part 42 inputs the signal from the drive are calculating part 41 to decide on the extent of interference with said predicted drive track, and a control part 43 generates a collision preventing signal when a collision is forecasted. A collision prevention processor 50 inputs the signal and performs processing for preventing the automobile from colliding, e.g. generates an alarm. |
