Patent number: 6742620Abstract: A power steering system in which an electric motor (9) makes available a damping torque to a steering system via a mechanical transmission (4). The transmission (4) is arranged between the steering wheel (2) and a steering rack (5). The electric motor (9) is actuated by a control unit (1) in accordance with the steering torque sensed by a sensor (3) and the vehicle speed sensed by a sensor (10). In addition, a damping module (8) of the control unit (1) receives binary or continuous signals relating to the braking state, in particular relating to the brake activation (11) and to cornering (9). By means of these signals the damping torque which is generated by the electric motor (9) can be adapted in such a way that vibrations which are caused by unequal wear of the brakes in the steering system are reduced.Type: GrantFiled: July 29, 2002Date of Patent: June 1, 2004Assignee: Ford Global Technologies, LLCInventors: Dirk-Uwe Eidam, Eric Leonard Branger, Stephan Presser

Patent number: 6729646Abstract: A method and system for controlling a vehicle occupant safety system based on crash severity. The system uses an acceleration signal indicating the acceleration of the vehicle upon occurrence of a crash to determine whether to trigger a restraint device. A controller implements a crash sensing algorithm to determine whether the severity of the crash warrants deployment of the safety restraint. The algorithm uses a predicted velocity and an acceleration peak time derived from the acceleration signal. The predicted velocity is indicative of the relative velocity between the passenger and the vehicle at a predetermined time following detection of a crash event. The acceleration peak time is the time period between peak acceleration values that correspond to contacting of significant structural elements of the vehicle, such as the bumper and the radiator.Type: GrantFiled: February 25, 1999Date of Patent: May 4, 2004Assignee: Siemens VDO Automotive CorporationInventor: Scott Morell
