Abstract
A vehicle braking system includes one or more traction motors and an electrical device configured to be electrically coupled with the one or more traction motors. The one or more traction motors are configured to propel a vehicle and to generate electric power during rollback of the vehicle down a grade. The electrical device is configured to consume the electric power generated from the rollback of the vehicle by performing work with the electric power during the rollback of the vehicle.
Claims20
A system comprising:
- one or more traction motors configured to propel a vehicle, the one or more traction motors configured to generate electric power during rollback of the vehicle down a grade;
- and
- a compressor configured to be electrically coupled with the one or more traction motors and fluidly coupled to an air reservoir of the vehicle, the compressor configured to consume the electric power generated by the one or more traction motors during the rollback of the vehicle by generating compressed air that is supplied to the air reservoir.
A method comprising:
- generating electric power from one or more traction motors of a vehicle during rollback of the vehicle down a grade, the one or more traction motors configured to propel the vehicle;
- controlling a compressor to consume the electric power generated from the rollback of the vehicle by generating compressed air;
- and
- supplying the compressed air, that is generated during the rollback of the vehicle, to an air reservoir to load the air reservoir.
A system comprising:
- traction motors configured to be disposed onboard a vehicle and to propel the vehicle;
- and
- one or more processors configured to control a first set of the traction motors to generate electric power via regenerative braking during rollback of the vehicle down a grade
- the one or more processors configured to control a second set of the traction motors to use at least some of the electric power generated by the first set during the rollback to provide torque to one or more of (i) stop the rollback of the vehicle down the grade or (ii) propel the vehicle up the grade.
