摘要： A system for indicating an impending vehicle maneuver within a predetermined distance is provided. The system includes a navigational system and a control module. The navigational system receives a vehicle destination and determines a current geographical vehicle position. The navigational system determines if the impending vehicle maneuver is required within the predetermined distance based on the vehicle destination and the current geographical vehicle position. The control module is in communication with the navigational system and a handwheel. The control module sends a signal that creates a steering assist torque in the handwheel if the impending vehicle maneuver is required.

摘要： A vehicle with an electric power steering system has a steering shaft with a resonant frequency of free rotational oscillation and a control which derives a driver assist torque signal, a return to center torque signal and an active damping torque signal and sums these signals to provide a motor command signal to the electric motor. The active damping torque signal is derived by filtering a generated steering shaft position signal in a filter having amplitude and phase characteristics of a differentiator from zero Hertz only through the resonant frequency of free rotational oscillation of the steering shaft and multiplying the filtered steering shaft position signal by a vehicle velocity factor derived from sensed vehicle velocity. Preferably, the electric motor is provided with one or more rotor position sensors used in the control thereof and rotor position signals from the rotor position sensors are provided as the steering shaft position signal.

摘要： Disclosed is a method for assisting the parking of a vehicle. The method includes determining a vehicle position relative to an obstacle. When the relative position meets a first set of criteria, a first torque pulse is delivered to the steering wheel in the first direction to cue an operator of the vehicle to turn the steering wheel in the first direction. When the relative position meets a second set of criteria, a second torque pulse is delivered to the steering wheel in the second direction, opposite to the first direction to cue the operator to turn the steering wheel in the second direction. A system for assisting the parking of a vehicle is also disclosed.
