Patent number: 11008037Abstract: A steering application executing on a vehicle control module receives a steering control input to control a steered wheel of a vehicle and, based on the steering control input, determines a setpoint value for the steered wheel. A diagnostic supervisor receives a measured value of the control attribute and the setpoint value; wherein the first diagnostic supervisor comprises a first model of a steering system of the vehicle. Based on the setpoint value and the first model, the diagnostic supervisor calculates a virtual value of the control attribute and, based on the virtual value and the measured value of the control attribute the first diagnostic supervisor determines an operating condition of the steering system of the vehicle.Type: GrantFiled: August 1, 2016Date of Patent: May 18, 2021Assignee: Crown Equipment CorporationInventors: Stephen T.

Patent number: 9868445Abstract: 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.Type: GrantFiled: August 11, 2016Date of Patent: January 16, 2018Assignee: Crown Equipment CorporationInventors: Stephen T.
