Diagnostic supervisor to determine if a traction system is in a fault condition
First Claim
1. A method comprising:
- receiving, by a steering application executing on a vehicle control module;
a steering control input to control a steered wheel of a vehicle;
based on the steering control input, determining, by the steering application;
a traction threshold value associated with a traction control attribute related to a traction wheel of the vehicle;
receiving by a first diagnostic supervisor executing on the vehicle control module;
a measured value of the traction control attribute, andthe traction threshold value;
when the measured value of the traction control attribute exceeds the traction threshold value, repeatedly calculating, by the first diagnostic supervisor, a respective difference between the traction threshold value and the measured value of the traction control attribute, to generate a set comprising a plurality of the respective differences; and
based on the plurality of respective differences, determining, by the first diagnostic supervisor, a first operating condition of a traction system of the vehicle.

Abstract
A steering application executing on a vehicle control module receives a steering control input to control a steered wheel of a vehicle. Based on the steering control input, the steering application determines a traction threshold value associated with a traction control attribute related to a traction wheel of the vehicle. A first diagnostic supervisor executing on the vehicle control module receives a measured value of the traction control attribute and the traction threshold value. When the measured value of the traction control attribute exceeds the traction threshold value, the first diagnostic supervisor repeatedly calculates a respective difference between the traction threshold value and the measured value of the traction control attribute to generate a set comprising a plurality of the respective differences. Based on the plurality of respective differences, the first diagnostic supervisor determines a first operating condition of a traction system of the vehicle.
