A traction application executing on a vehicle control module receives a traction speed control input to control a traction wheel of the vehicle. Based on the traction speed control input, the traction application determines a first setpoint value of a control attribute related to the traction wheel. A first diagnostic supervisor receives a measured value of the control attribute related to the traction wheel, and the first setpoint value from the traction application. The first diagnostic supervisor comprises a first model of a traction system of the vehicle. Based on the first setpoint value and the first model, the first diagnostic supervisor calculates a first virtual value of the control attribute related to the traction wheel. Based on the first virtual value and the measured value of the control attribute, the first diagnostic supervisor determines a first operating condition of the traction system of the vehicle.
