Title:
STEERING CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP3185726
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To assist the steering torque by setting the reference lines extended along a lane, and arranged in parallel with each other in a width direction of the lane, and generating the steering torque by selecting a target travel line from the reference lines corresponding to the travelling condition of a vehicle.
SOLUTION: A steering controller comprises an electronic control unit(ECU) 10. The steering controller comprises a video camera 12 to pick up an image of a road surface. An image processer 14 is connected with the video camera 12. The image processer 14 extracts a white line from an image signal. An output signal of the image processer 14 is supplied to the EUC 10 to recognize an area of a lane. The steering controller comprises a steering wheel 26, and connects a steering shaft 28. A steering angle sensor 30 is mounted on the steering shaft 28, for generating an output signal corresponding to a steering angle θ of the steering wheel 26. A torque sensor 32 is mounted on the steering shaft 28, for outputting an electric signal corresponding to the steering torque T. Whereby the steering assist of high practicality can be performed.
