Abstract
A start threshold value for rollover prevention control is changed based upon a ratio between an actual lateral G and a reference lateral G. Accordingly, the ratio between the actual lateral G and the reference lateral G is a parameter that indicates a vehicle condition, i.e., the potential for vehicle rollover that includes both the vehicle weight and the center of gravity height. It is therefore possible to set a start threshold value that considers the vehicle weight, center of gravity height and the like.
Claims13
A vehicular rollover prevention control device configured such that a rollover prevention control is executed when a rollover status value indicating a tendency of the vehicle to rollover exceeds a predetermined start threshold value, the vehicular rollover prevention control device comprising:
- an actual lateral acceleration detecting unit configured to detect an actual lateral acceleration generated by the vehicle;
- a reference lateral acceleration detecting unit configured to detect a reference lateral acceleration which does not include a gravity component of the vehicle;
- a ratio calculating unit configured to calculate a practical ratio between the actual lateral acceleration detected by the actual lateral acceleration detecting unit and the reference lateral acceleration detected by the reference lateral acceleration detecting unit;
- and
- a start threshold value changing unit configured to learn the practical ratio and to change the start threshold value based upon the practical ratio between the actual lateral acceleration and the reference lateral acceleration calculated by the ratio calculating unit.
