PROBLEM TO BE SOLVED: To realize control of steering transmitting characteristics optimum for recognizing driving behavior of a driver, controlling the steering transmitting characteristics corresponding to the driving behavior and carrying out specific driving behavior of the driver in steering control of a vehicle. SOLUTION: In the steering device for a vehicle, a ratio (in the following, referred to a steering angle ratio) of a steering amountθinputted to a steering wheel by the driver and a steered angleδw of a steered wheel 9 is varied. A traveling environment detection means 22 detect traveling environment of the vehicle based on an information from a front side road state detection means 12 and a car speed sensor 13. Thereby, a driving behavior recognition means 21 recognizes the specific driving behavior of the driver (maintaining of lane or changing of the lane) and a steering angle ratio Nd is determined in a steering angle ratio (steering transmitting characteristic) setting means 25 based on the result of the recognition. When a steering angle ratio (steering transmitting characteristic) correction coefficient determination means 24 recognizes starting of change of the lane Cs, it calculates a steering angle ratio correction coefficient Kp. A steering angle ratio (steering transmitting characteristic) correction means 27 corrects the steering angle ratio Np based on the coefficient Kp. COPYRIGHT: (C)2004,JPO&NCIPI |
