Steering system with lane keeping integration
First Claim
1. A system for steering a vehicle comprising:
- an actuator disposed in a vehicle to apply torque to a steerable wheel;
a driver input device disposed in the vehicle receptive to driver commands for directing the vehicle;
a first sensor disposed in said vehicle for determining an intent of a driver and generating a first signal indicative thereof;
a lane keeping system for detecting a location of the vehicle relative to a lane marker and generating a lane position signal indicative thereof and transmitting at least one of a lane position signal and a lane position deviation;
a controller in operable communication with said actuator, said driver input device, said first sensor, and said lane keeping system, said controller providing a command to said actuator responsive to said intent of said driver, said lane position, and a desired lane position; and
wherein said controller executes a lane keeping algorithm comprising a single control loop based on at least one of said lane position and said lane position deviation.

Abstract
A system for steering a vehicle including: an actuator disposed in a vehicle to apply torque to a steerable wheel; a driver input device receptive to driver commands for directing the vehicle; and a sensor for determining an intent of a driver and generating a signal indicative thereof. The system also includes: a lane keeping system for detecting a location of the vehicle relative to a lane marker and generating a lane position signal indicative thereof; a controller in operable communication with the actuator, the driver input device, the first sensor, and the lane keeping system. The controller provides a command to the actuator responsive to the intent of the driver, the lane position, and a desired lane position. The controller executes a lane keeping algorithm consisting of a single control loop based on at least one of the lane position and the lane position deviation.
