摘要： A method for controlling a limited by-wire active front steering system includes measuring an input steering angle, determining a tire saturation limit, and comparing the saturation limit to the input angle. A target actuator angle from a steering actuator is limited when the input angle is greater than the saturation limit. A constant value provides a fixed steering gear ratio when the input angle is less than the saturation limit. A limited by-wire steering system for a vehicle includes a steering device, a sensor for measuring an input steering angle, a controller for calculating a first target actuator angle when the input angle is less than a threshold, and a second target actuator angle when the input angle is greater than the threshold. The threshold is a calibrated saturation limit of a road wheel of the vehicle.

摘要： An active suspension system and method for controlling the height of a vehicle. In an exemplary embodiment, the active suspension system receives information from one or more input sources, including both internal and external vehicle inputs, and uses that information to actively control the vehicle height. By doing so, the active suspension system can reduce aerodynamic drag on the vehicle and improve the vehicle's fuel economy, ride comfort, handling, and other aspects of operation. Some examples of external vehicle inputs that may be used include: short-range road and vehicle information, as well as long-range traffic, road and route information.
