Abstract
A control system (18) for an automotive vehicle (10) has a first roll condition detector (64A), a second roll condition detector (64B), a third roll condition detector (64C), and a controller (26) that uses the roll condition generated by the roll condition detectors (64A–C) to determine a wheel lift condition. Other roll condition detectors may also be used in the wheel lift determination. The wheel lift conditions may be active or passive or both.
Claims16
A system for an automotive vehicle having a wheel comprising:
- a first roll condition detector generating a first roll condition signal;
- a second roll condition detector generating a second roll condition signal;
- a third roll condition detector generating a third roll condition signal;
- and
- a controller coupled to the first roll condition detector, the second roll condition detector and the third roll condition detector, said controller determining wheel lift in response to the first roll condition, the second roll condition and the third roll condition.
A method for controlling an automotive vehicle having an axle and wheels comprising:
- determining a first roll condition;
- determining a second roll condition;
- determining a third roll condition;
- and
- generating a wheel lift status signal in response to the first roll condition, the second roll condition and the third roll condition.
