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 comprising a hand wheel disposed in said vehicle operative to receive a steering command for controlling a direction of said vehicle comprising a torque applied by a driver to said hand wheel;
a first sensor disposed in said vehicle for sensing said torque applied by said driver to said hand wheel and generating a first signal indicative thereof;
a lane keeping system for detecting a location of said 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 steering command 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, and wherein said lane keeping algorithm includes a helper mode and an autonomous mode, wherein the helper mode is at least one of enabled and disabled responsive to receiving said first signal and determining that said torque applied by said driver to said hand wheel is a steering command for controlling a direction of said vehicle.

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.
