Method of producing a straight-on travel signal |
摘要 |
Wheel speeds on each side of the vehicle are added, and the sums are subtracted to form a difference VXU which is time filtered to produce a filtered difference VXG. As long as VXU does not exceed VXG by more than a speed dependent threshold, a signal indicating straight line travel is produced. This signal can be cancelled when VXG exceeds a vehicle dependent threshold and is also blocked when the vehicle speed falls below a minimum, when the ABS is operating, or when the vehicle is decelerating. The signal indicating straight line travel accounts for tire tolerance and can be used to control vehicle dynamics, for example by preventing an increase in brake pressure or engine braking when the vehicle is travelling in a curve.
