Abstract: PROBLEM TO BE SOLVED: To apply proper steering reaction force to an operation part according to the steering of wheels in a steering device for a vehicle of a steer-by-wire system having a connection part for mechanically connecting a steering force transmission mechanism and a reaction force transmission mechanism. SOLUTION: A reaction force motor 14 is mechanically connected to a steering wheel 11 via a reaction force transmission mechanism 13, applying reaction force to the steering wheel 11. A steering motor 15 is connected to the wheel side via a steering force transmission mechanism 16, steering the wheels. Part of the reaction force transmission mechanism 13 and part of the steering force transmission mechanism 16 are constituted by part of a planetary gear mechanism, and connected to a part of the parts of the planetary gear mechanism (a connection part 21) provided that the reaction force and the steering of wheels are allowed to operate independently. An electronic control system 55 corrects the operation control of the reaction force motor 14 so as to reduce the effect on the reaction force by the operation of the connection part 21 accompanying the steering of wheels.

Abstract: PROBLEM TO BE SOLVED: To suppress an increase of steering force caused by the assist-off state occurring on a steering system of a transmission ratio variable mechanism and a steering force auxiliary mechanism by changing the transmission ratio of the transmission ratio variable mechanism to a larger value with a transmission ratio setting means based on the travel state of a vehicle when the steering force auxiliary mechanism exceeds the prescribed operating speed. SOLUTION: A transmission rate G is set according to a vehicle speed V (S 202), and whether the vehicle speed V is Vth or below or not is judged (S 204). If the vehicle speed V is higher than Vth, the value of the transmission ratio G is left as it is. If the vehicle speed V is a low speed lower than Vth, a correction coefficient K is set to a value larger than 1 when the steering speed dθh/dt exceeds a specified value in the steering direction specified with right steering as positive and left steering as negative (S 206), and the transmission ratio G is changed based on the arithmetic result K.G of the transmission ratio G and the correction coefficient K(S 208). The assist-off state can be prevented by setting the transmission ratio G to a larger value in a high-steering speed region.

Abstract: PROBLEM TO BE SOLVED: To set a preferable transmission ratio appropriate for steering operation during turning that involves acceleration or deceleration by determining a correction amount for a basic transmission ratio based on a steering state while a vehicle is in acceleration/deceleration state, and setting the transmission ratio of a transmission ratio variable mechanism. SOLUTION: A steering control unit 70 sets a transmission ratio G of a transmission ratio variable mechanism 30 based on a basic transmission value Gbase which is set according to a vehicle speed V and correction amount α which is set according to a steering state and an acceleration/deceleration state of a vehicle. When the steering wheel is turned, the correction amount α is set to -α0 and when the steering wheel is returned, the correction amount α is set to α0 . Accordingly, when turning the steering wheel during acceleration/deceleration, the transmission ratio becomes more quick than the basic transmission ratio Gbase and a steer amount of the steering wheel when turning can be reduced. When returning the steering wheel during acceleration/deceleration, the basic transmission ratio Gbase becomes more slow, so that a turning angle of a wheel for the same steering angle is directed to a position closer to a neutral position, thereby the steering wheel steer amount during returning is reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce differential controlled variable and eliminate deviation of a neutral point by making a transmission ratio varying means of a steering transmission system connecting a steering handle and a steering wheel a frictional type continuously variable transmission. SOLUTION: When vehicle speed detected by a speed sensor 48 is inputted in an electronic controller(ECU) 46, the slide location of a ring body 14e of a continuously variable transmission 14 is determined according to speed and a gear shift instruction value for the slide is outputted. A gear ratio variable motor 30 revolves based on the gear shift instruction value, the revolution is transmitted to a worm gear 32, a guide member 34 moves along a slide pin 36, the ring body 14e of the continously variable transmission 14 moves upward at the time of low speed and moves downward at the time of high speed, each gear ratio is made small or large and the steering of a steering handle 10 can be performed in a quick or slow state. The ECU 46 determines the theoretical value of the gear ratio by the speed detected by the speed sensor 48, compares the value with a target steering angle and corrects deviation, and deviation of a neutral point can be eliminated by operational controlled variable.
