Abstract
A vehicle control system is provided for controlling adhesion of wheels to a route surface. The control system includes one or more processors configured to determine adhesion values representative of adhesion between the wheels of a vehicle and the route surface based on angular speeds of the wheels. The one or more processors are configured to generate a target slip value for the wheels that are coupled with at least two different axles of the vehicle by processing the adhesion values and modifying the target slip value continuously in time to maximize an average value of the adhesion values of the wheels. The one or more processors also are configured to control a torque applied to at least one of the axles based on the target slip value.
Claims20
A vehicle control system comprising:
- one or more processors configured to determine adhesion values representative of adhesion between wheels of a vehicle and a route surface based on angular speeds of the wheels,
- the one or more processors configured to subsequently calculate a target slip value for the wheels that are coupled with at least two different axles of the vehicle using the adhesion values that were determined, the one or more processors also configured to repeatedly modify the target slip value to increase an average value of the adhesion values of the wheels,
- the one or more processors configured to control a torque applied to at least one of the axles based on the target slip value that is calculated.
A method comprising:
- determining adhesion values representative of adhesion between wheels of a vehicle and a route surface based on angular speeds of the wheels;
- calculating a target slip value for the wheels that are coupled with at least two different axles of the vehicle, the target slip value calculated using the adhesion values that were determined;
- controlling a torque applied to at least one of the axles based on the target slip value;
- and
- repeatedly changing the target slip value as the vehicle moves based on changes in the adhesion values to increase an average value of the adhesion values.
A system comprising:
- one or more processors configured to determine adhesion values representative of adhesion between wheels of a vehicle and a route surface based on angular speeds of the wheels,
- the one or more processors configured to subsequently calculated a target slip value for the wheels that are coupled with at least two different axles of the vehicle using the adhesion values that were determined,
- the one or more processors configured to control a torque applied to at least one of the axles based on the target slip value and to repeatedly change the target slip value as the vehicle moves based on changes in the adhesion values to increase an average value of the adhesion values,
- wherein the wheels include a leading wheel and a trailing wheel along a direction of movement of the vehicle, the one or more processors are configured to increase the target slip value that is calculated associated with the leading wheel to clean the route surface with the leading wheel prior to travel of the trailing wheel.
