Honda Develops New Driving Aid, the Honda Intelligent Driver Support (HIDS) System

Tokyo, September 19, 1997 --- Honda Motor Co., Ltd. introduced today the "Honda Intelligent Driver Support" (HIDS) system, a new driving aid compensating for careless human errors.

This system reduces driver burden by compensating for mistakes made under normal driving circumstances. It recognizes road lanes (CCD camera), and measures the distance to the car ahead (laser-type radar sensor) to regulate speed, car-to-car distance and to help remain within a given lane.

  • Lane center deviation warning and in-lane driving control

    This system recognizes road lanes and sets a directional target aiming at the middle of the road lane. The system then compares this target with actual car direction and makes steering corrections to remain on target. It also emits a warning when the car deviates too far away from the lane center.

  • Driving between car lanes warning and in-lane driving control

    The system's laser-type radar senses the driving conditions ahead of the car and determines the car that is ahead on the same lane through its speed- and yaw rate-sensors. If car-to-car distance is too small, the system reduces speed mostly through throttle control and, if necessary, brake application until normal distance is restored. In case the situation requires a heavier than normal brake application, the system will also send a warning to the driver. If the car ahead is driven faster and increases the car-to-car distance, the system will function as a normal cruise control system.
