摘要： PURPOSE:To detect the degree of yaw rate without time integration and suppress errors for highly accurate detection. CONSTITUTION:A pair of acceleration detecting means 11 and 12 are placed distant from each other along a straight line on the same plane of a vehicle so as to detect the acceleration in the straight line direction. A yaw rate calculation means 15 calculates the yaw rate of the vehicle based on the acceleration detected by the means 11 and 12.

摘要： PURPOSE:To provide improved reliability and size reduction of a hydraulic control valve in a hydraulic brake device which controls the hydraulic pressure of a hydraulic pressure source electrically for feeding it to a wheel cylinder. CONSTITUTION:Hydraulic control valves 50-56 are mounted between a master cylinder 12 and wheel cylinders 22, 24, 34, 36, the hydraulic pressure of an accumulator 82 is controlled according to master cylinder hydraulic pressure, and the hydraulic pressure is electrically-controlled by a force motor. When master cylinder hydraulic pressure exceeds a prescribed value, cut valves 190, 250 are closed, the hydraulic pressure control force of a control piston which receives the master cylinder hydraulic pressure is restricted, so it is possible to make the diameter of the control piston without increasing the size of the force motor, and attain excellent output hysteresis characteristics. If hydraulic pressure is not fed to the front wheel cylinders 22, 24, the cut valve 250 is not closed, and large rear wheel braking force is attained. It is thus possible to avoid reduction of braking force of the whole vehicle with high efficiency.

摘要： PURPOSE:To omit a useless distribution control and to reduce a load applied to a brake and the like, by converting a standard value of a drive-braking force distribution control device according to the car speed, in a drive-braking force distribution control device to start the control when the difference between an actual turning condition amount and an object in turning condition amount of a vehicle exceeds the standard value. CONSTITUTION:In a braking force distribution control device of the lateral and the longitudinal distribution control type, a braking force lateral difference DELTAB is operated by making it as the product of the difference between an objective yaw rate gamma* and an actual yaw rate gamma, and a control gain K (S1 to 7), so as to decide to make a standard value H larger as the car speed V is smaller (S9 and 10), and when the absolute value of the braking force lateral difference DELTAB is larger than the standard value H, the distribution control is carried out (S11, 14 to 20), and when the DELTAB is not larger than the H, the distribution control is not carried out (S11 and 12).

摘要： PROBLEM TO BE SOLVED: To provide a steering device which enables a large tilt operation while suppressing the deterioration of merchantability.
SOLUTION: When a rotational angle detected by rotational angle sensor 15 is out of a prescribed angular range ϕ
0 ± α (S18:No) and a first electromagnetic clutch 13 is disengaged (S20), a control unit 50 drives a turning electric motor 32 to control a rotational angle of a universal joint 14 to fall within the prescribed angular range ϕ
0 ± α. The rotational angle control controls the rotational angle of the universal joint 14 to allow the first steering shaft 121 and second steering shaft 122 to carry out a tilt operation at a large angle. Since the rotational angle control is executed when the electromagnetic clutch 13 is disengaged, the steering wheel 11 is not rotated during the rotational angle control. As a result, a steering shaft is allowed to carry out a large tilt operation while suppressing the deterioration of merchantability.

摘要： PROBLEM TO BE SOLVED: To attain smooth vehicle behavior even when characteristic difference is present on a turning actuator.
SOLUTION: The vehicle steering device 10 is a vehicle steering device each independently provided with turning motors 24 relative to a pair of left and right steered wheels included in the vehicle. A steering angle sensor 34 detects a steering angle input by a driver. A target turning angle setting part 50 sets a target turning angle of the pair of left and right steered wheels according to the detected steering angle. A turning motor control part 66 controls the turning motor 24 so as to become the target turning angle set by the target turning angle setting part 50. An actual turning angle sensor 42 detects the actual turning angles of the pair of left and right steered wheels respectively. An actual turning angle difference comparison part 54 determines whether or not the actual turning angle difference of the pair of left and right steered wheels is larger than a predetermined value. A target turning angle correction part 62 corrects the target turning angle of at least one steered wheel to output it to the turning motor control part 66 when it is determined that the actual turning angle difference is larger than the predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide a steering device for a vehicle facilitating the driving of the vehicle by suitably controlling the turned state of a turned wheel relative to the operation of a steering wheel by a driver. SOLUTION: An operation state determination part 42 determines the turning operation state of the steering wheel 11 by the driver. A reference point setting part 43 sets a steering-holding operation point, a cutting-in operation point and a returning operation point as reference points based on the determined operation state of the steering wheel 11. A turning angle variation characteristic determination part 44 determines a cutting-in operation variation characteristic of a non-linear shape that the variation characteristic of the turning angle δ varied to the reference point and the maximum operation point is downward projected or a returning operation variation characteristic of a non-linear shape that the variation characteristic of the turning angle δ varied to the reference point and a neutral operation point is upwardly projected using the determined operation state of the steering wheel 11 and the set reference point. Thereby, it can be controlled such that the turned state the left and right front wheels FW1, FW2 can be controlled so as to always become equal in turned states according to turning operation of the steering wheel 11.

摘要： PROBLEM TO BE SOLVED: To provide a steering-by-wire type steering device of a vehicle capable of easily and precisely detecting abnormality of a contact breaker to selectively connect a steering handle and a steering wheel. SOLUTION: An ECU 45 for checking controls an electromagnetic clutch 31 in a cutting state on a step S11 in a state when an electric motor 22 for steering stops and inputs a steering angle θ and steering torque T on a step S12. It proceeds to a step S14 when torque T is less than torque To by determining whether the steering torque T is less than the target torque To or not on a step S13. Thereafter, it sets an abnormality flag MBF at "0" to express normality of abnormality on the clutch 31. In the meantime, it proceeds to a step S15 when the torque T is more than the torque To on the step S13. Thereafter, it sets the flag MBF at "1" to express abnormality. This abnormality determination is performed when the steering angle θ is less than a specified steering angle θo by processing of a step S16. COPYRIGHT: (C)2007,JPO&INPIT
