Abstract: When information of an obstacle is not outputted from a radar device, a presumption device presumes at least a present value of a distance between a vehicle and the obstacle based on information in a memory part obtained until the time, and a contact-possibility judgment device judges a possibility of contact of the vehicle with the obstacle based on the information from the presumption device. A detection device is provided for detecting conditions at the time when the information of the obstacle is not outputted from the radar device, for example, a relation of relative position of the obstacle to the vehicle. Further, a restriction device is provided for restricting the presumption by the presumption device according to the relation of relative position. Thus, a possibility of contact of the vehicle with the obstacle running forward of the vehicle is appropriately judged and mis-operations of an alarm, an automatic braking and the like are prevented, while ensuring running safety.

Abstract: The vehicle is provided with a radar unit for detecting an obstacle existing ahead in the course of the running way along which the vehicle is running. When the radar unit detects a variation in its detectable region, such as a detectable distance or a detectable area range in left and right directions, from the detectable region to be detectable during ordinary running, a safety unit such as an alarm unit or an automatic brake unit is operated. A control logic for operating a collision-avoiding system for avoiding a collision with the obstacle existing ahead, such as an alarm unit or an automatic brake unit, is altered to a safe side on which safety in driving the vehicle is improved, when the detectable region is varied.

Abstract: A method to determine a horizontal error of a radar device mounted on a vehicle along with the mounting error or imbalance in the diameters of wheels based on an echo signal from a reflector provided on a road. A vehicle's traveling locus is stored in advance as a reference locus obtained from the distance L between the vehicle and reflector and the direction .theta..sub.R. A traveling locus when the vehicle is actually traveling in a straight line where the steering handle is kept in a neutral position is compared with the previously stored reference locus. A horizontal error is obtained from the traveling locus on the coordinate axis .theta..sub.R and the shift from the reference locus.

Abstract: An obstacle sensing apparatus for vehicles is provided in which detection of obstacles is performed efficiently by predicting the traveling path of the vehicle appropriately when detection of obstacles by a radar unit is limited to a region along the traveling path. The apparatus is provided with a radar unit for transmitting radar waves ahead of the vehicle and sensing obstacles present ahead of the vehicle, a steering angle sensor for sensing the steering angle of the vehicle, and a yaw rate sensor for sensing the yaw rate produced by the vehicle. First traveling-path predicting device predicts a traveling path of the vehicle based upon the steering angle, and second traveling-path predicting device predicts a traveling path of the vehicle based upon the yaw rate. One of these traveling paths is selected in dependence upon the operating state of the vehicle and detection of articles by the radar unit is carried out within a limited region along the traveling path selected.
