Abstract
A system includes a sensor and a controller. The sensor is configured to detect sliding of a wheel of a vehicle. The controller is configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation. The controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.
Claims20
A system comprising:
- a sensor configured to detect sliding of a wheel of a vehicle;
- and
- a controller configured to communicate with the sensor and a traction motor operatively connected to the wheel such that the traction motor selectively applies forces in at least one direction to the wheel during operation;
- wherein the controller is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.
A method for a vehicle, comprising:
- detecting sliding of a wheel on a route surface resulting from a frictional braking force;
- and
- applying a motoring slide reducing force to the wheel via a traction motor operatively connected to the wheel, the motoring slide reducing force being configured to directly oppose the frictional braking force applied to the wheel.
A controller comprising:
- at least one processor;
- and
- one or more input/output ports;
- wherein the at least one processor is configured to communicate through the one or more input/output ports with a traction motor and a sensor that is configured to detect sliding of a wheel of a vehicle, and the traction motor operatively connects to the wheel so as to selectively apply a motoring or a braking force to the wheel during operation;
- and
- wherein the at least one processor is further configured to direct the traction motor to apply a motoring slide reducing force to the wheel when the sensor detects sliding of the wheel resulting from a frictional braking force.
