Abstract
When a curve exists in the direction of travel of a vehicle and information for this curve is inputted from a navigation system and the shape of the actual curve in the road changes gently with respect to the curve shape of the navigation system, the change in the curvature of the actual curve actually becomes smaller based on an integral value of the yaw rate, vehicle speed, and the yaw rate. It is then detected that the navigation system and the actual vehicle behavior of the system do not coincide, and the output of unnecessary control commands such as alarms, deceleration and steering and the like is halted. Namely, it is judged that curve information from the navigation system is erroneous, and outputting of unnecessary control commands can be avoided before something happens.
Claims11
A curve approach control device for predicting and judging the approach of a curve based on information for a curve ahead for a vehicle and outputting prescribed control commands comprising:
- means for comparing and judging matching between curve information supplied by a navigation system and real curve information based on actual vehicle behavior, and means for stopping outputting of the control commands when it is judged that the curve information from the navigation system and the real curve information do not match.
