    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： 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： 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： 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.
