    摘要： When the vehicle is traveling on a motorway, a display control module of a display controller determines that an obstacle is unlikely to be present, and restricts the display pattern of a sensed image sensed of an image sensing device to be displayed on a display device. Even when the vehicle is traveling on the motorway, if no stalled vehicle is detected, the display control module displays the sensed image without restricting it, thereby supporting drive operation of the driver.

    摘要： A traveling-path temporary-setting unit 21 sets a plurality of temporary traveling paths with different curvatures, and a calculation unit 22 calculates distances between the temporary traveling paths and preceding vehicles detected by a radar unit 1. In case of a properly-set temporary traveling path, the path and running loci of the preceding vehicles are on a concentric circle. In this case, the preceding vehicles are running along this temporary traveling path, and a time change amount of calculated distances is approximately "0". A traveling-path determination unit 23 determines, one temporary traveling path having the minimum time change amount in the distances, as a traveling path of the vehicle.

    摘要： 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.

    摘要： In a vehicle running mode detecting system, a relative speed of a vehicle, equipped with the vehicle running mode detecting system, to a forward object is calculated on the basis of a time elapsed from a reference time based on which the time elapsed is measured and a change in the distance between the vehicle and the forward object during the time elapsed. Whether the vehicle is running in a constant distance mode where the distance between the vehicle and the forward object is kept substantially constant or in a varying distance mode where the vehicle is accelerating or decelerating relative to the forward object and the distance between the vehicle and the forward object is varying is determined on the basis of the change in the distance between the vehicle and the forward object. The reference time is updated less frequently when the vehicle is running in the constant distance mode than when the vehicle is running in the varying distance mode.
