Abstract: PROBLEM TO BE SOLVED: To provide a steering control device for a vehicle to execute suitable steering control from the time at which control is started by a method wherein combination of a relative angle sensor and an absolute angle sensor from a point of view of control is used as a detecting sensor. SOLUTION: A working angle sensor is provided to detect the working angle of the actuator of a transmission ratio varying mechanism by an absolute angle. A working angle θm0 detected by a working angle sensor is stored during completion of control (S122). During reopening of control, based on the working angle θm0 and a transmission ratio G0, the absolute angle θh0 of a steering handle is estimated (S104).

This transmission ratio is defined by (steering amount of the steering wheel 10)/(steering amounts of the steering wheels 24FL and 24FR). Also, the variable gear ratio unit 14 is connected to an ECU 30 via a motor driver 36, and operated by receiving the control signal of this ECU 30. When a wheel state is changed to change the motion characteristic of the vehicle, the transmission ratio of the steering transmission system is changed according to the vehicle state.

Abstract: PURPOSE:To perform objective evaluation simply and readily by computing the area rate based on the number of the dots of a high-luminance part for each area, each area and the area in the specified evaluating range, and obtaining the amount of variation and of the rate and the difference between the maximum area and the minimum area. CONSTITUTION:Light is emitted from a light source on a painted film. The light is received at an angle where the positive reflected light does not enter. The specified evaluating range of the painted film is binarized by high and low luminance parts based on the luminances. For the high luminance part, where the dot is observed, the number of the dots at each area is obtained. The area rate is computed by dividing (area X number) by the specified area. Then, the amount of variation DELTAR and the difference DELTAS between the maximum and minimum areas are obtained based on the area rate of each area. The smaller the amount of variation DELTAR and the larger the difference DELTAS of the areas, the depth feeling is high. Therefore, the depth feeling is especially high when the amount of change DELTAR of the area rate is small and the difference DELTAS of the areas is large. The depth feel can be quantitatively evaluated by the comparison with the preset measuring value.

Abstract: PROBLEM TO BE SOLVED: To solve such a problem that in differential steering control, when a steering wheel is quickly reciprocated, it is feared that an actuator is more driven under the influence of a controlled variable, and the reactive force is transmitted to the wheel to give a sense of incongruity in steering to an operator. SOLUTION: When the gain Ts of a differential value α which is set in response to the steering angular speed dθh/dt, it set based on a map shown in Fig, the gain is decreased with increasing the steering frequency (f), and the controlled variable is suppressed in response to the steering angular speed under the condition where switching is frequently operated.
