    摘要: A vehicle control system for detecting an obstacle present ahead on the road in the course of travel of a vehicle, comprising a first laser radar mounted on the vehicle which emits an electromagnetic beam to detect the obstacle present ahead on the road, and second and third laser radars which measures distances between the first laser radar and the road surface at different angles. The system determines whether the first laser radar is mounted on the vehicle such that the laser beam central axis is horizontal or inclines upward or downward relative to the road surface or vehicle body, based on the distances, a height of the first laser radar from the road surface, the angles at which the distances are measured and reference values. The system may correct the inclination if determined. With the arrangement, the system ensures detection of an obstacle on the road without fail and conduction of a desired obstacle avoidance control.

    摘要: A system for controlling running safety of a vehicle having at least a brake, a steering mechanism manipulated by a vehicle operator, a laser radar for detecting an obstacle present ahead on a course of travel of the vehicle, and a brake actuator mechanism actuating the brake independently of the vehicle operator manipulation. In the system, a first threshold value (defined in terms of relative distance between the vehicle and the obstacle) for avoiding contact with the obstacle by steering and a second threshold value for avoiding contact by operating the brake actuator mechanism are determined and are compared with the detected relative distance. When the detected relative distance is less than the first threshold value, the brake actuator mechanism is immediately operated to generate a relatively small deceleration, thereby enabling effective obstacle avoidance to well meet the intention and desires of the vehicle operator, without causing a problem of interference with the steering of the vehicle operator, while preventing the control accuracy from being degraded.

    摘要: In an obstacle detection system for a vehicle which has a radar having an electromagnetic wave transmission device and a reflected wave reception device, the electromagnetic transmission device transmits electromagnetic waves in a direction in which the vehicle is traveling, and the reflected wave reception device receives reflected waves produced when the electromagnetic waves transmitted from the electromagnetic wave transmission device are reflected by an object present in the traveling direction of the vehicle. The system detects obstacles present in the traveling direction of the vehicle based on the result of a radar search operation, and it is possible to identify only those objects detrimental to the traveling of the vehicle as obstacles. An obstacle decision device decides whether or not the object detected by the radar is an obstacle, by using the detected value determined by a vehicle speed detection device which detects the speed of the vehicle, the calculated value determined by a relative distance calculation device that calculates a relative distance to the object present in the traveling direction of the vehicle based on the result of search operation by the radar, and the calculated value determined by an overlap calculation device that calculates an overlap in the width direction of the vehicle between the vehicle and the object according to the result of the search operation by the radar.
