  • Power-assisted steering system and method with compensation of pull induced by tire pressure loss
    Patent number: 6250421
    Abstract: A power-assisted steering system (10) for a vehicle that has steerable front wheels (26 and 28) that are inflated. The system (10) includes a manually operated steering member (12) for steering input from a vehicle operator. A series of components (14-22) relays forces between the steering member (12) and the steerable front wheels (26 and 28). A motor (32) provides an assist steer force to steer the steerable wheels (26 and 28) in response to a force applied to the steering member (12). At least one tire pressure sensor (e.g., 66) monitors an inflation pressure of one of the front wheels (e.g., 26). A controller (42) determines and accordingly controls a compensating steer force to the steerable wheels (26 and 28), responsive to the monitored inflation pressure, which attenuates force transmitted to the steering member (12) due to front wheel inflation condition.
