Abstract
A vehicle includes at least one wheel hub, a wheel hub speed sensor, and a controller. The wheel hub is configured to be coupled to a drive wheel. The wheel hub speed sensor is proximate to the wheel hub and is configured to generate a wheel hub speed signal that facilitates determination of a rate and direction of rotation of the wheel hub. The controller is configured to communicate power to a motor assembly coupled to the wheel hub to rotate the wheel hub at a particular rate and in a particular direction. The particular rate and the particular direction are associated with a particular position of a plurality of positions of a steering control.
Claims20
A vehicle comprising:
- a wheel hub configured to be coupled to a drive wheel;
- a wheel hub speed sensor proximate to the wheel hub configured to generate a wheel hub speed signal that facilitates determination of a rate and direction of rotation of the wheel hub;
- and
- a controller configured to communicate power to a motor assembly coupled to the wheel hub to rotate the wheel hub at a particular rate and in a particular direction, wherein the particular rate and the particular direction are associated with a particular position of a plurality of positions of a steering control and the wheel hub speed signal.
A drive system for a vehicle comprising:
- a motor assembly configured to be coupled to a wheel hub;
- a wheel hub speed sensor configured to generate a wheel hub speed signal that facilitates determination of a rate and direction of rotation of the wheel hub;
- and
- a controller configured to communicate power to the motor assembly, based on the wheel hub speed signal, to rotate the wheel hub at a particular rate and in a particular direction, wherein the particular rate and the particular direction are associated with a particular position of a plurality of positions of a steering control.
A method for operating a vehicle, the method comprising:
- generating, by a wheel hub speed sensor proximate a wheel hub, a wheel hub speed signal that facilitates determination of a rate and direction of rotation of the wheel hub;
- and
- communicating, by a controller in communication with the wheel hub speed sensor, based on the wheel hub speed signal, power to a motor assembly coupled to the wheel hub to rotate the wheel hub at a particular rate and in a particular direction, wherein the particular rate and the particular direction are associated with a particular position of a plurality of positions of a steering control.
