PURPOSE:To prevent an accident at the time of the right or left-turn of a vehicle before it happens. CONSTITUTION:A steering angle detector 101 detects the steering angle of the steering device of the vehicle 1. A traveling range calculator 102 estimates and calculates a range where the vehicle 1 travels from the steering angle detected by the steering angle detector 101. A sensor 103 detects an obstacle or the presence of another vehicle and a person within the range estimated and calculated by the traveling range calculator 102 and the range of an angle theta1 by an ultrasonic sensor, etc. The sensor 104 detects the person or another vehicle moving toward the range estimated by the traveling range calculator 102 from the rear of the vehicle 1 by the ultrasonic sensor, etc., before these go into the range of a backward angel theta2. An alarm generator 105 generates an alarm to a driver 2 information detected by the sensors 103, 104 in the obstacle within the range where the vehicle 1 travels based on the steering angle detected by the traveling range calculator 102. |
