Abstract
A vehicle traveling-path prediction apparatus that detects a stationary object in front of the vehicle by utilizing an obstacle detection device instead of a yaw rate sensor, and predicts a traveling path based on the detected stationary object. The apparatus comprises control unit having an obstacle detection device which receives a detection signal from a radar head unit to detect an obstacle in front of the vehicle, stationary object detection device which receives an output signal from the obstacle detection device to detect the obstacle as a stationary object, a first traveling-path prediction device which receives an output signal from the stationary object detection device, and if there is a stationary object in front of the vehicle, calculates a radius of curvature R1 of a first traveling path, based on data indicative of running conditions of the vehicle, a second traveling-path prediction device which calculates a radius of curvature R2 of a second traveling path, based on a velocity V0 and a steering angle .theta.H, and a selection device which receives a detection signal from the radar head unit and if there is no stationary object in front of the vehicle, selects the second traveling path R2 calculated by the second traveling-path prediction device.
