1. A method comprising:
- iteratively performing;
a) receiving, by a steering application executing on a vehicle control module;
a steering control input from a vehicle steering device to control a steered wheel of a vehicle;
a measured value of a steering control attribute related to the steered wheel; and
a measured value of a traction control attribute related to a traction wheel of the vehicle;
b) based on the steering control input, the measured value of the steering control attribute and the measured value of the traction control attribute, determining, by the steering application;
a first setpoint value of the steering control attribute related to the steered wheel for use in controlling a steering motor associated with the steered wheel;
a target steering angle of the steered wheel of the vehicle;
c) receiving, by a traction application executing on the vehicle control module of the vehicle;
a traction speed control input to control the traction wheel of the vehicle, andthe target steering angle, from the steering application;
d) based on the traction speed control input and the target steering angle, determining, by the traction application;
a second setpoint value of the traction control attribute.

Abstract
Based on a steering control input, a measured value of the steering control attribute and a measured value of the traction control attribute received by a steering application, determining: a first setpoint value of the steering control attribute; a target steering angle of the steered wheel of the vehicle. Based on receiving, by a traction application executing on the vehicle control module of the vehicle: a traction speed control input to control the traction wheel of the vehicle, and the target steering angle, from the steering application, determining, by the traction application: a second setpoint value of the traction control attribute.

10. A system on a vehicle comprising:
-
a controller comprising; a first input configured to receive a steering control input from a steering device on the vehicle to control a steered wheel of the vehicle; a second input configured to receive a measured value of a steering control attribute related to the steered wheel; a third input configured to receive a measured value of a traction control attribute related to a traction wheel of the vehicle; a fourth input configured to receive a traction speed control input to control the traction wheel of the vehicle; a memory coupled with the controller and storing code executable by the controller, the executable code comprising a steering application and a traction application configured to iteratively perform; a) based on the steering control input, the measured value of the steering control attribute and the measured value of the traction control attribute, determining, by the steering application; a first setpoint value of a steering control attribute related to the steered wheel of the vehicle for use in controlling a steering motor associated with the steered wheel; a target steering angle of the steered wheel of the vehicle; b) receiving, by the traction application; a traction speed control input to control the traction wheel of the vehicle, and the target steering angle, from the steering application; and c) based on the traction speed control input and the target steering angle, determining, by the traction application; a second setpoint value of the traction control attribute. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 20)
