Abstract
A steering control system for a vehicle that considers the limitations of at least one of the vehicle and the environment is contemplated. The steering control system can receive a vehicle characteristic, an environmental condition, a desired amount of turning, and a desired velocity of the vehicle. Based on some, or all of these parameters, the steering control system can determine at least one of a wheel torque, a wheel angle, a wheel camber, and a wheel suspension for a desired vehicle path to enhance vehicle performance.
Claims21
A steering control system for a vehicle having a first wheel and a center of mass, comprising:
- an environmental condition sensor that is configured to detect an environmental condition;
- a steering angle sensor configured to sense a desired amount of turning;
- a speed sensor configured to sense a desired velocity of the vehicle;
- a sensor configured to sense a first vehicle characteristic;
- a calculating controller coupled to the environmental condition sensor, the steering angle sensor, the sensor, and the speed sensor, and configured to receive the environmental condition, the desired amount of turning, the first vehicle characteristic, and the desired velocity to thereby determine a correcting wheel torque and a correcting wheel angle of the first wheel;
- an effecting controller configured to apply the correcting wheel torque and the correcting wheel angle to the first wheel;
- and
- wherein the first vehicle characteristic is a change in a shape of the vehicle that alters the center of mass of the vehicle.
(canceled)
A method of controlling a vehicle having a first wheel and a center of mass, comprising:
- detecting an environmental condition, a desired amount of turning, a change in a shape of the vehicle that alters the center of mass of the vehicle, and a desired velocity of the vehicle;
- calculating a correcting wheel torque and a correcting wheel angle of the first wheel based on the change in the shape of the vehicle, the environmental condition, the desired amount of turning, and the desired velocity;
- and
- adjusting a wheel torque and a wheel angle of the first wheel based on the correcting wheel torque and the correcting wheel angle of the first wheel.
A method of controlling a vehicle having a first wheel and a center of mass, comprising:
- detecting a change in the center of mass of the vehicle;
- calculating a correcting wheel torque and a correcting wheel angle of the first wheel based on the change in the center of mass of the vehicle;
- and
- adjusting a wheel torque and a wheel angle of the first wheel based on the correcting wheel torque and correcting wheel angle of the first wheel.
