Abstract

The present invention relates to an active rear wheel steering control method and apparatus. In particular, provided is a controller of an active rear wheel steering control system, the controller includes a processor and a software module. The software module includes commands that are executed so as to determine rear wheel steering angle, condition of a vehicle, form functions and rear wheel steering commands by the processor.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 151946, filed February 12, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The technical field of the invention generally relates to the control of an active rear steering (ARS) system of a vehicle. Background technique [0004] Modern vehicles sometimes incorporate active vehicle control subsystems. One such subsystem for providing automatic rear wheel steering is known as an active rear wheel steering (ARS) control system. The ARS control system modifies the operator's steering commands so that the vehicle more closely follows the vehicle operator's desired steering path while increasing vehicle stability and handling. However, at high speeds, some ARS control systems make steering corrections that degrade the overall performance of the vehicle. Contents of the invention [0005] Various embodi...
