Abstract: In a steer-by-wire system 10, a first steering reaction force made-up value (Hc1) is determined in dependence on a road reaction force (W), and a second steering reaction force made-up value (Hc2) is determined in dependence on a steering position (X) of a steering handle 11 or steerable wheels 50. A steering reaction force command value (H) is generated from both of the first steering reaction force made-up value (Hc1) and the second steering reaction force made-up value (Hc2) the weightings on which are adjusted by respective weighting gains (G1, G2), and the ratio of the weighting gains is properly altered in dependence on the state of a road surface. Thus, it can be realized to provide the steer-by-wire system 10 capable of adjusting the steering reaction force to be sensitive or insensitive to the state of the road surface.

Abstract: In a steering apparatus, in accordance with a grip limit control process (30b?), it is determined whether or not a grip degree ? estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree (??), and in the case that it is determined that an estimated grip degree (?) is less than the predetermined grip degree (??), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M), thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering.

Abstract: Disclosed is a steer-by-wire system and a control program therefor which are capable of preventing a steering handle from being turned excessively. According to the steer-by-wire system and the control program, when drive electric current to a steering actuator is restrained to restrict the steering of steerable road wheels, the steering reaction force to the steering handle is increased thereby to make the steering handle hard or unable to turn further. Thus, the steering handle can be prevented from being turned excessively. Further, when the steering actuator is heated beyond a predetermined temperature, such is judged as the overload on the steering actuator thereby to restrain the drive electric current to the steering actuator. Therefore, it can be obviated that the steering actuator is overheated to suffer failure.

Abstract: The present invention relates to a steering control apparatus for maintaining operating characteristics which do not change from when conditions are normal and when an impairment occurs. The apparatus includes a plurality of motors for driving a steered wheel and a plurality of ECUs, each associated with one of the motors. When the steering control apparatus is operating normally, a torque command representing torque required to turn the steered wheel is generated. The torque command is divided in accordance with the number of motors. Each of the ECUs control the associated motors in accordance with a corresponding one of the distributed torques.

Abstract: A controller of a steer-by-wire steering apparatus determines whether voltage applied to a steering motor in accordance with a current command value has reached a predetermined voltage. Based on the result, the controller selects one of the value of an actual current through the steering motor and a current command value. Based on the selected current value, an axial force applied to a steering rod is estimated. Based on the estimated axial force, a counter torque motor is controlled. Therefore, An error or oscillation occurring in the estimated steering axial force is prevented, and the driver is suppressed from further turning the steering wheel when the voltage applied to the steering motor is saturated.

Abstract: A steer-by-wire steering apparatus for a vehicle includes an elastic member couples a reaction force actuator to a steering wheel. With respect to the elastic member, a side closer to the steering wheel is referred to as a primary side, and a side closer to the reaction force actuator is referred to as a secondary side. A steering wheel position detector is located at the secondary side. Therefore, the apparatus is capable of giving a feel of a steering reaction force equivalent to an ordinary mechanically connected steering apparatus to an operator and secures stability of a control system.

Abstract: In accordance with a steering apparatus (20), a grip state between a ground surface on which a steered wheel is grounded and the steered wheel is estimated by a grip degree estimation arithmetically operating process (30a) which is arithmetically operated by AFS_ECU (30), and VGRS target angle is set such that a steering gear ratio is increased in the case that the grip degree gets close to a grip limit on the basis of an estimated grip state, in accordance with a grip degree vs gear ratio map (30b). Accordingly, since it is possible to estimate the grip degree which is changed in correspondence to a magnitude of the road surface it, for example, in the case that the steered wheel gets close to the grip limit, it is possible to increase the steering gear ratio so as to set large even at a time when the vehicle runs at the low speed.
