First Claim
Patent Images
1. A device for detecting a counter-steer condition of a vehicle, comprising:
- a steering angle sensor for measuring a steering angle;
a steering angular speed detecting means for measuring a steering angular speed;
storage means for storing at least signs of current and previous values of the steering angle and the steering angular speed;
means for comparing the current steering angular speed with a predetermined threshold value; and
a controller which produces a signal to indicate a counter-steer condition when the signs of the current and previous values of the steering angle differ from each other, the signs of the current value of the steering angle and the current and previous values of the steering angular speed coincide with each other, and the current value of the steering angular speed is greater than the predetermined threshold value.

Abstract
Provided is a counter-steer condition detecting device which is suited to be used in combination with steering control systems based on the control of the magnitude of the effort required for the vehicle operator to steer the vehicle depending on the behavior of the vehicle. An over-steer condition may be detected by evaluating the signs of the current and previous values of the steering angle and the steering angular speed, and the magnitude of the steering angular speed when the steering angle passes a certain monitor level.
