摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering gear capable of changing to have steering feeling suitable for a situation of a vehicular front side without impairment of perception properties and moving properties. SOLUTION: An electronic control unit 35 obtains road information obtained from a navigation device A, namely information indicating a curve radius R in a front side of a road and a slope S. The unit 35 determines a situation in the front side of the road on the basis of obtained information, and properly changes steering torque Td that has an index relation with a steering angle θ. Therefore, the driver can be given steering feeling that is suitable for a traveling environment. In this case, even if the steering feeling is changed, the perception properties of estimated lateral acceleration Gd is not changed before/after changing according to the Weber Fechner's law.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering gear capable of certainly reporting a generated abnormal condition without impairment of perception properties and moving properties even when an abnormal condition occurs. SOLUTION: When an abnormal condition (failure) occurs in steering, an electronic control unit 35 changes steering torque Td by adopting a map N2 increasing(namely, weighting) the steering torque Td on the basis of a converting table of the steering torque Td to a steering angle θ. The steering torque Td to a steering wheel 11 operation by a driver is made to be large as compared with that under a normal condition. At that time, even if the steering torque Td is increased, the perception properties of an estimated lateral acceleration Gd is not changed before/after the generation of the failure according to the Weber Fechner's law.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular steering device positively reducing the influence of lateral force of a lateral slip angle amount of a vehicle body acting on a vehicle during the vehicle turns, and stabilizing a behavior at the time of turning of the vehicle. SOLUTION: An electronic control unit 45 inputs a lateral slip angle β of the vehicle body in a step S11. Next, the electronic control unit 45 inputs correction amount N inputted by a driver in a step 12. Then, the electronic control unit 45 calculates a target steering angle δa by subtracting a correction item (N×β) from the rotating amount (K1×θ) of a steering output shaft 13 in a predetermine relationship with the rotating amount of a steering input shaft 12, in order to reduce lateral force generated in the vehicle due to the lateral slip angle β of the vehicle body, in a step S15. The electronic control unit 45 drive-controls an electric motor 21 of a variable gear ratio actuator 20 until the rotating amount of the steering output shaft 13 becomes the target steering angle δa, in steps S16, 17.

摘要： PURPOSE:To reduce both the oscillation of a body and change in attitude at a time of cornering by configurating a device in such a way that a transverse acceleration of the body is detected in order to compute the amount of variations in loads for controlling the increase or decrease in forces acting on between each of wheels and the body. CONSTITUTION:Sensors such as a transverse acceleration sensor 19, a rolling angular acceleration sensor 20, a longitudinal acceleration sensor 21, and a vehicle speed sensor 26 are provided for a vehicle where each of four servo actuators 1 (1fr, 1fl, 1rr, and 1rl) which is provided for each of a front right, a front left, a rear right, and a rear left wheel respectively, is separately controlled so as to control the attitude of a body. Outputs from the acceleration sensor 19 and 20 are inputted into an automatic front/rear load distributor 25 through a change-over switch 24 together with the output from the vehicle sensor 26. Then the amount of variations for loads which act on between each of the front and rear wheels on one side and the body, is computed based on the output from the transverse acceleration sensor. And then the resultant of the said computation is operated based on a ratio corresponding to a vehicle speed so as to distribute it to the front and rear wheels for controlling each of the actuators 1.
