Abstract
A directional control system for a vehicle includes a driver input device operable to receive a driver input corresponding to a desired lateral acceleration of the vehicle. The system also includes a controller in communication with the driver input device, the controller being operable to generate a control signal in response to comparing the received desired lateral acceleration and an actual lateral acceleration of the vehicle. The system further includes an actuator in communication with the controller, the actuator being operable to effect a change in the direction of travel of the vehicle in response to the control signal.
Claims26
A directional control system for an automobile, the system comprising:
- a driver input device operable to receive a driver input corresponding to a desired lateral acceleration of the automobile;
- a controller in communication with the driver input device and the automobile, the controller operable to generate a control signal in response to comparing the received desired lateral acceleration and an indication of actual lateral acceleration of the automobile;
- and
- an actuator in communication with the controller, the actuator operable to effect a change in the direction of travel of the automobile in response to the control signal.
An automated method for controlling the direction of travel of a vehicle, the method comprising:
- receiving a driver input corresponding to a desired lateral acceleration of the vehicle;
- comparing, by a controller, the desired lateral acceleration to an actual lateral acceleration of the vehicle;
- and
- effecting a change in the direction of travel of the vehicle in response to comparing the desired lateral acceleration to the actual lateral acceleration.
A method for controlling the steering of an vehicle, the method comprising:
- receiving a first signal indicative of a desired lateral acceleration of the vehicle and a second signal indicative of an actual lateral acceleration of the vehicle;
- receiving a third signal indicative of the rate of change in the actual lateral acceleration of the vehicle;
- comparing the first and second signals;
- and
- changing the orientation of at least one wheel of the vehicle in response to the comparison of the first and second signals and further in response to the third signal.
A system, the system comprising:
- a driver input device operable to generate a first signal indicative of a desired lateral acceleration of an automobile;
- an accelerometer operable to generate a second signal indicative of an actual lateral acceleration of the automobile;
- a tachometer operable to generate a third signal indicative of a rate of change in the actual lateral acceleration of the automobile;
- a controller in communication with the driver input device, the accelerometer, and the tachometer, the controller operable to generate a control signal in response to comparing the first signal and the second signal and further in response to the third signal;
- and
- an actuator in communication with the controller and the tachometer, the actuator operable to adjust the orientation of at least one wheel of the automobile in response to the control signal.
