Parametric remedial action strategy for an active front steer system

摘要

A vehicle parametric active front steering (AFS) system remedial action is described herein. AFS system modules inter-communicate via messages containing parameters. The AFS system detects a message error, determines an invalid parameter, and takes appropriate remedial action. An error is detected if an error condition is satisfied or if occurrence of incorrect messages reaches or exceeds a certain predetermined frequency. The AFS system takes the remedial action by setting default values of valid parameters corresponding to the invalid parameter.
