Abstract

A system and method herein relate to vehicle control by adjusting a torque distribution of the vehicle. The system includes a first motor configured to provide a torque to a first wheel, and a delivery system configured to controllably apply a traction control compound to a route on which the first wheel is configured to travel. The system also includes a controller circuit having one or more processors. The controller circuit is configured to control the delivery system to apply the traction control compound to the route based on a monitored temperature of the first motor.

Claims (34)

1. A system comprising:

a reservoir configured to hold a traction control compound;

a delivery system coupled to the reservoir, wherein the delivery system includes a first opening positioned proximate to a first wheel;

a controller circuit having one or more processors, wherein the controller circuit is configured to:

receive respective temperature measurements of a first motor and a second motor, wherein the first motor is configured to provide a torque to the first wheel; and

control transfer a portion of the traction control compound from the reservoir to the first opening when the temperature measurement of the first motor is above a predetermined non-zero threshold.

2. The system of claim 1 , wherein the controller circuit is configured to control transfer the portion of the traction control compound from the reservoir to the opening when the temperature measurement of the first motor is above the predetermined non-zero threshold and the temperature measurement of the second motor is below the predetermined non-zero threshold.

3. The system of claim 1 , wherein the predetermined non-zero threshold is based on a designed operation specification of the first and second motors.

4. The system of claim 1 , wherein the delivery system includes a junction switch configured to direct the traction control compound to a first pipe arm or a second pipe arm of the delivery system based on a forward motion of a vehicle system.

5. The system of claim 4 , wherein the first and second pipe arms extend in opposing directions.

6. The system of claim 1 , wherein the traction control compound is sand or sandite.

7. The system of claim 1 , wherein the traction control compound is configured to increase an adhesion between an outer surface area of the first wheel and a route.

8. The system of claim 1 , further comprising a sensor configured to measure an amount of traction control compound within the reservoir, wherein the controller circuit is configured to generate a fault when the traction control compound is below a threshold and reduce an amount of traction control compound transferred to the opening based on the fault.

9. The system of claim 1 , wherein the controller circuit is further configured to adjust an amount of the traction control compound transferred to the opening based on a duration of the temperature of the first motor above the predetermined non-zero threshold or an amount of the traction control compound within the reservoir.

10. A method comprising:

monitoring a first temperature of a first motor and a second temperature of a second motor, wherein the first motor is configured to provide a torque to a first wheel; and

transferring a portion of a traction control compound from a reservoir to a first opening when the first temperature is above a predetermined non-zero threshold to deposit the traction control compound on a portion of a route proximate to the first wheel.

11. The method of claim 10 further comprising adjusting a junction switch associated with the first opening based on a forward motion of a vehicle system, wherein a position of the junction switch controls amounts of the traction control compound sent to a first pipe arm that defines the first opening and sent to a second pipe arm.

12. The method of claim 10 , wherein the predetermined non-zero threshold is based on a designed operation specification of the first and second motors.

13. The method of claim 10 , wherein the traction control compound is sand or sandite.

14. The method of claim 10 , wherein the traction control compound is configured to increase an adhesion between an outer surface area of the first wheel and a route.

15. The method of claim 10 , further comprising adjusting an amount of the traction control compound transferred to the opening based on a duration of the first temperature of the first traction motor above the predetermined non-zero threshold.

16. The method of claim 10 , further comprising adjusting an amount of the traction control compound transferred to the opening base on an amount of the traction control compound within the reservoir.

17. A system comprising:

a first motor configured to provide a torque to a first wheel;

a delivery system configured to controllably apply a traction control compound to a route on which the first wheel is configured to travel; and

a controller circuit having one or more processors, wherein the controller circuit is configured to control the delivery system to apply the traction control compound to the route based on a monitored temperature of the first motor.

18. The system of claim 17 , further comprising:

a second motor; and

one or more sensors configured to generate temperature measurements of the first motor and second motor;

wherein the delivery system includes a reservoir configured to hold the traction control compound and a first opening coupled to the reservoir, wherein the first opening includes an opening proximate to the first wheel for application of the traction control compound to the route; and

wherein the controller is configured to: monitor temperature data of the first motor and the second motor based on the temperature measurements; and transfer a portion of the traction control compound from the reservoir to the opening when the temperature data of the first motor is above a predetermined non-zero threshold.

19. The system of claim 18 , wherein the delivery system includes a junction switch configured to direct the traction control compound to a first pipe arm or a second pipe arm based on a forward motion of a vehicle system.

20. The system of claim 17 , wherein the traction control compound is sand or sandite.
