摘要： PURPOSE:To make inspection of a device without disassembling it by passing a current, at which a neutral position energizing spring is set to the maximum and an elastic body is deformed to the maximum, and judging fatigue condition, etc., based on the rear wheel steer angle, when the steering mode is set to the inspection mode. CONSTITUTION:When a vehicle provided with a rear wheel steering mechanism 14 for steering by an electric motor 20 against an energizing force of a neutral position energizing spring 89 for rear wheels 15 comes in a repair shop, etc., the steering mode is set to the inspection mode if a condition that the vehicle speed is approx. zero and a steering wheel 11 cannot be operated is continued for a specified period. When the mode is set to the inspection mode, an electric current value of the electric motor 20 is set to a current value at which the length of the spring 89 becomes the maximum and the deformation of a sheet member, which is an elastic body provided between the spring 89 and a gear housing, becomes the maximum to steer the rear wheels. Under this condition, rear wheel steer angle is compared with a specified reference value to inspect fatigue and deterioration of the mechanical elements of the rear wheel steering mechanism.

摘要： PROBLEM TO BE SOLVED: To freely select a plurality of rudder angle ratio modes with a driver and to improve maneuverability by providing a target rudder angle ratio setting means setting a plurality of target rudder angle ratio modes, and selecting a target rudder angle ratio mode based on the mode set information from a manually operated switch means. SOLUTION: When a handle is operated, the displacement quantity of the moving housing of a variable-rudder angle ratio mechanism 5 is detected by a rudder angle ratio sensor 10, and it is sent to a control means 13 as the actual rudder angle ratio signal Cj. The control means 13 calculates the deviation ΔC between the target rudder angle ratio signal Cs corresponding to the vehicle speed signal V from a vehicle speed sensor 12 and the actual rudder angle ratio signal Cj with a deviation calculating means 22 and feeds the motor control signal Vo based on the deviation ΔC to a motor driving means 14 from a drive control means 23. When a switch means 15 is operated by a driver, the target rudder angle ratio mode is selected by a mode selecting means 24, and the target rudder angle ratio signal is determined by a target rudder angle ratio setting means 21 based on the selected target rudder angle ratio mode.

摘要： PROBLEM TO BE SOLVED: To provide a good steering feeling by controlling a transfer ratio of a steering unit through control of an operation amount of a motor generator based on a steering torque signal sent from a steering torque sensor so as to change a turning amount of a steering system. SOLUTION: The transfer ratio control means 14 is provided with a microprocessor for executing various operating function, processing function, and memory function. A target turning amount signal is generated based on an electric operation amount signal OS corresponding to the operation amount of the steering wheel 2 supplied from the operation amount sensor 17 and an electric steering torque signal TS corresponding to the steering torque supplied from the steering torque sensor 18. Furthermore, a motor generator control signal VO obtained by combining an ON signal corresponding to the target turning amount signal and a pulse width modulation signal is supplied to the motor generator driving means 15. As a result, a good steering feeling for the driver's intention can be obtained, thus reducing the load of the driver who has been driving for a long time. Therefore, excessive steering operation in case of emergency can be prevented.

摘要： PURPOSE:To make an accurate decision of fault in a short time by a constitution wherein power supply conditions to a motor is monitored, a time interval where current supply or voltage application to the motor is constant is detected, and a decision is made that the motor is faulty if thus detected time interval exceeds a predetermined time. CONSTITUTION:Upon occurrence of ON failure in the FET of a motor drive circuit 23, a mono-stable multivibrator 54 outputs a single pulse at the rising time of voltage to be applied on a motor 40 and thereby the output signals S from failure detecting circuits 51, 52 are kept in Low state. Output signal from a mono-stable multivibrator 53 goes Low when 0 applying voltage is sustained due to OFF failure or when the applying voltage goes 0 for a predetermined interval of single revolution due to abrasion of one brush of the motor 40. If the Low potential endures for a predetermined time, a decision is made that the motor is faulty.

摘要： PURPOSE:To obtain a high turning property in the region of a small front wheel steering angle without impairing driving stability by applying a steering angle ratio changed by the vehicle speed smaller than that for the steering angle ratio at the preset steering angle in the region where the steering angle ratio is positive and the front wheel steering angle is the preset steering angle or below. CONSTITUTION:A controller 20 corrects the steering angle ratio K1 in response to the front wheel steering angle thetaF when the steering angle ratio K1 determined based on the vehicle speed V by a vehicle speed sensor 19 is a positive value, and the steering angle ratio when the front wheel steering angle thetaF is the preset steering angle (b) or below, e.g. the steering angle near the neutral position at the time of a steering start, is made smaller than the steering angle ratio when the front wheel steering angle thetaF is the preset steering angle (b). The stable behavior tendency of a vehicle near the neutral position is suppressed, the turning behavior tendency is increased, and excellent turning property is obtained.

摘要： PURPOSE:To obtain high turn performance without deteriorating stability by determining in accordance with a detected car speed the ratio of a steering angle and its phase corrected in accordance with a detected steering condition and calculating being based on a front wheel steering angle a rear wheel target steering angle steering a rear wheel. CONSTITUTION:A controller 16 inputs signals from a steering angle sensor 14, steering speed sensor 15, steering torque sensor 40, car speed sensor 20 and a rear wheel steering angle sensor 24 and determines ratio of a steering angle and its phase in accordance with a detected car speed, calculating a target steering angle of rear wheels 18RR, 18RL from the steering angle ratio and phase being based on a front wheel steering angle detected in the steering angle sensor 14. Here the car speed is left as determining its correction region, when the car speed is in this region, the steering angle ratio and phase are corrected in accordance with a detected steering condition. For instance in the case of a steering speed in a large value, even at the time of high speed running, the rear wheel is steered in a reverse phase. The rear wheel is steered by an electric motor 21 so as to obtain the rear wheel target steering angle. Thus by obtaining high turn performance without deteriorating stability, driving performance can be improved.
