    摘要： 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.

    摘要： 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.

    摘要： When the vehicle has deviated or is deviating from a lane on which the vehicle has been or is running, the deviation of the vehicle from the lane can be suppressed, for example, by allowing the steering wheel to be operatively rotated prior to an intention of the operator. The timing of suppressing the deviation of the vehicle can be altered in accordance with conditions including, for example, the existence of a lane in the direction of deviation of the vehicle on which another vehicle is running in the same direction, the existence of an obstacle in the direction of deviation of the vehicle, the existence of an adjacent lane in the direction of deviation of the vehicle on which another vehicle is running in the opposite direction, a state of the lane on which the vehicle is running, such as a curved lane or a straight lane, a direction of deviation is outside or inside the curved lane or a lane width, a vehicle speed, a steering angle of a steering wheel, an extent of vision, and so on.

    摘要： An automatic braking system for a motor vehicle includes a sensor for detecting a distance and a relative speed between the vehicle and an obstacle in front of the vehicle. A judging device for judging an alarm sounding region and a region in which the vehicle has a possibility of contact with the obstacle, based on the detected distance and the relative speed and an automatic brake for automatically braking respective wheels when the judging device judges the region in which the vehicle has a possibility of the contact with the obstacle are provided. The automatic brake incudes a vacuum type booster which has a first chamber to which negative pressure is introduced and a second chamber to which atmospheric pressure is introduced. The first chamber is connected to the down stream portion, from a throttle valve, in an intake path of an engine. The booster uses a pressure difference between the negative pressure and the atmospheric pressure. A device for increasing the negative pressure in the first chamber of the automatic brake prior to the operation of the automatic brake is also provided.
