Abstract: PROBLEM TO BE SOLVED: To provide a headlamp light distribution control device and a headlamp device capable of guiding a driver not to perform excessive steering when a turning behavior of a vehicle is understeer. SOLUTION: When the turning behavior of the vehicle is in neutral steer, an irradiation angle of a headlamp is controlled to be a target irradiation angle determined by a target irradiation angle determining part 3A. When the turning behavior of the vehicle is transferred to the understeer, the irradiation angle of the headlamp is controlled to be a corrected irradiation angle increased and corrected by increasing and correcting the target irradiation angle determined by the target irradiation angle determining part 3A by a target irradiation angle correcting part 3D. As a result, an irradiating direction of the headlamp is directed to the turning direction inside the vehicle as compared with that when the turning behavior is in the neutral steer, the driver does not feel the lack of steering, and thus the driver is guided not to perform excessive steering.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicular steering control device capable of compatibly suppressing generation of vibration in a hands-off-the-wheel state and suppressing positional deviation caused by the disturbance. SOLUTION: A driver torque estimation unit 42 estimates the steering torque Th of a driver from the input angle θh as the output of an input angle sensor 30 and the input torque T as the output of a torque sensor 31. A hands-off determination unit 43 determines whether or not a hand is off by comparing the absolute value of the estimated steering torque Th with the predetermined value ε1. On the other hand, a balance point determination unit 44 determines whether or not a balanced state is obtained by comparing the absolute value of the input torque T with another predetermined value ε2. When it is determined that the hands-off state and the balanced state are obtained, a changing unit 46 changes a switch to a lower side in the figure, and the target turning angle can be reduced by multiplying the predetermined gain G (less than 1) according to the input torque T by the target output angle θpm by a target turning angle adjustment unit 45.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle steering device precisely detecting a steering torque and properly controlling steering.
SOLUTION: A steering assist force is set on the basis of a steering torque outputted from a steering torque sensor in the normal operation of a torque sensor 6 (S14). On the other hand, in the abnormal operation of the steering torque sensor 6, the steering torque is detected on the basis of control deviation of a transmission ratio variable mechanism 4 (S18, S20), and the steering assist force is set based on the detected steering torque, so that a power steering mechanism 7 is controlled to give the set steering assist force to a steering force transmission system (S22). Thereby, even when the steering torque sensor 6 is in an abnormal operation condition, the steering can be properly assisted, so as to properly control steering.

Abstract: PROBLEM TO BE SOLVED: To provide a control device of an electric power steering capable of operating stable steering, suppressing influence of a difference in temperature and heat generation.
SOLUTION: In the ECU 10 (a control device of an electric power steering), the stable steering suppressing the influence of the difference in temperature and heat generation can be operated by correcting the temperature to the current command for driving an electric motor 23. Since a temperature sensor 55 is disposed not on a motor drive circuit 52 itself but on a substrate 54 mounting the motor drive circuit 52, the flexibility of disposition of the temperature sensor 55 is increased. Since the temperature sensor 55 for heat generation control of the spiral cable 23S provided on the electric motor 23 is used in common for correcting of the current command, the number of parts is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a steering control system for a vehicle capable of precisely discriminating whether writing of a final angle position fails or not upon termination of a last time vehicle driving operation. SOLUTION: A write completion information storage part 115 capable of switching the memory content between a first memory condition and a second memory condition which indicate completion/failure of writing of the final angle position into the final angle position storage part 115, is provided on the steering control part 100 and the final angle position is written into the final angle position storage part 115 upon termination of vehicle driving operation. Moreover, corresponding to this, the memory content of the write completion information storage part 115 is set as the first memory condition. At the time of starting of next time vehicle driving operation, the steering control part 100 judges whether the final angle position stored in the final angle position storage part 115 is a right value or not by referring to the memory content of the write completion information memorizing part. It determines whether the final angle position is adopted as an initial angle position or not. Only when the final angle position is adopted, drive control of the wheel steering shaft by an actuator is started. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide a steering device for a vehicle with a transmission ratio variable unit capable of actuating a locking device irrespective of whether the transmission ratio variable unit is in an actually abnormal state or in a failure state when the probability of abnormality or failure of a motor or the like of the transmission ratio variable unit is predicted and the probability is high. SOLUTION: The device includes a motor overheating detection means and a lock device. The motors overheating detection means detects whether the motors driving the transmission ratio variable unit and/or a current supply cable (henceforth motors) becomes in an overheating state by carrying of current. The locking device fixes the steering wheel shaft and the output shaft of the motor by mechanically directly connecting them, and stops the transmission ratio variable function of the transmission ratio variable unit when the motors overheating detection means detects or presumes the overheating of the motors.

Abstract: PROBLEM TO BE SOLVED: To prevent driving force of a transmission ratio varying mechanism from acting in the direction for returning a steering handle by performing a driving control according to a steering angle of an operation handle and limiting a change of a transmission ratio to a quick side when a turning wheel angle of a turning wheel exceeds a prescribed range. SOLUTION: An input shaft 20 and an output shaft 40 are connected via a transmission ratio varying mechanism 30 and the input shaft 20 is connected with a steering handle 10. The output shaft 40 is connected with a rack shaft 51 via a rack-and-pinion type gear device 50 and turning wheels FW are connected with both sides of the rack shaft 51. Because a steering angle of the steering handle 10 is corresponding to a rotary angle of the input shaft 20, the input shaft 20 is provided with a steering angle sensor 21 for detecting a steering angle θh. Based on the steering angle θh and an operating angle θm, a turning wheel angle of the wheel FW is detected. A steering control device 70 performs an output processing for a control signal Is to an actuator 31 based on the signals and controls the transmission ratio varying mechanism 30.
