Device and method for controlling a steering system in a vehicle
First Claim
1. A method for controlling a vehicle steering system having a plurality of subsystems that generate steering requests for the steering system, the method comprising the steps of:
- receiving a plurality of steering requests at an electronic control unit;
receiving a plurality of vehicle parameter signals at the electronic control unit, the vehicle parameter signals being representative of a driving situation for each subsystem in the plurality of subsystems;
setting an order of priority for application of the steering requests by the electronic control unit as a function of the driving situation for each subsystem; and
controlling the application of the steering requests to the vehicle steering system in the set order of priority and within a predetermined overall torque limit.

14. A vehicle steering control system comprising:
-
an electronic control unit (ECU) configured to receive steering requests and at least one signal representative of a driving situation from a plurality of subsystems; a predetermined overall torque limit for steering requests; and a modular logic unit in the ECU having a plurality of modules configured to arbitrate, prioritize and apply the steering requests in response to the driving situation and within a predetermined overall torque limit. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
