Running-safety system for an automotive vehicle
First Claim
1. A running-safety system for an automotive vehicle, comprising:
- obstacle detecting means for detecting an obstacle in a detectable region existing ahead of the automotive vehicle in a running way along which the vehicle is running;
detection means for detecting a variation from a normal state of the detectable region; and
safety means for taking an action to make running of the vehicle safe when the detection means detects a variation of the detectable region from the normal state.

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.

41. A running-safety system for an automotive vehicle, comprising:
-
obstacle detecting means for detecting an obstacle existing ahead in a running way along which the vehicle is running; detection means for detecting a decrease in performance of detection of the obstacle by said obstacle detecting means; and safety means for taking an action to make running of the vehicle safe when said detection means detects the decrease in the performance of detection of the obstacle by said obstacle detecting means. - View Dependent Claims (42, 43, 44, 45, 46)
