Electric power assist steering motor sensor redundancy
Abstract:
An electric power assist steering motor sensor redundancy system is disclosed comprising a brushless motor selectively providing a first predetermined level of steering assistance for a vehicle. A first sensor and second sensor provide position information of the brushless motor to a motor controller. An alternative sensing system for the brushless motor may be selectively utilized to provide position information of the brushless motor to the controller when at least one of the first sensor or the second sensor fails.
