Abstract
In one or more embodiments described herein, devices, systems, methods and/or apparatuses are described that can facilitate provision of a single motor torque request based on a driver assistance system pinion angle request. The motor torque request can be generated absent arbitration between two or more requests from two or more different controller components. A device can comprise a steering control system that generates a motor torque request based on a single request from a single first controller component.
Claims20
A method, comprising:
- generating, by a steering control system, a pair of initial control requests based on a closed-loop control scheme;
- generating, by the steering control system, a secondary pinion request being an output of an aggregation of the pair of control pinion requests;
- and
- generating, by the steering control system, a motor torque request based on the secondary pinion request, wherein the secondary pinion request and the motor torque request are generated, by the steering control system, during different, non-overlapping time intervals.

A steering control system, comprising:
- a first controller that employs a closed-loop control scheme to generate a pair of initial control requests and that generates a secondary pinion request based on an aggregation of the pair of initial control requests;
- and
- a second controller that, based on the secondary pinion request, generates a motor torque request, wherein the secondary pinion request and the motor torque request are generated during different, non-overlapping time intervals.
A system, comprising:
- a vehicle comprising
- a motor controller,
- a first controller that employs a closed-loop control scheme to generate a pair of initial control requests and that generates a secondary pinion request based on an aggregation of the pair of initial control requests, and
- a second controller that, based on the secondary pinion request, generates a motor torque request to the motor controller, wherein the secondary pinion request and the motor torque request are generated during different, non-overlapping time intervals.
