摘要： PROBLEM TO BE SOLVED: To enhance the degree of freedom in design of a power transmission device using a polymer actuator. SOLUTION: The power transmission device is equipped with an engagement mechanism which freely connects two rotational elements. The engagement mechanism is actuated by a polymer actuator 5. The polymer actuator 5 telescopically is extended and contracted by being supplied with an electric power from a power receiver 61 which generates electric power by being affected by a magnetic field generated by a magnetic field generator 71 mounted to a fixing member 1, and thereby engages with the engagement mechanism. Also, a signal is transmitted to a radio receiver 81 using a radio transmission 64 according to an electromotive force generated by a reaction force that the polymer actuator 5 receives when engaging with the engagement mechanism. A controller 8 grasps an actual engaging force of the engagement mechanism from a counter-electromotive force, and thereby performs feedback control for controlling the intensity of the magnetic field of the magnetic field generator 71.

摘要： PROBLEM TO BE SOLVED: To provide a failure detection device of a power transmission device capable of detecting OPEN failure of corresponding shift solenoid valves with a simple construction when an ON command of the shift solenoid valves.
SOLUTION: When an ON command is issued to either shift solenoid valve, it is determined whether or not the ON command is directed to a single shift solenoid valve (step S1). If the commanded is single, the shift solenoid valve is turned on (step S3) and an actual electric current passing the shift solenoid valve is detected with an electric current detection means (step S4). When a difference between an electric current value to be supplied and the actual electric current value becomes equal to or less than a first threshold for a predetermined time (steps S5, S6), an electronic control unit serving as a failure determination means determines that OPEN failure occurs in the shift solenoid valve (step S7) and informs an operator of an error (step S8).

摘要： PROBLEM TO BE SOLVED: To allow a driver to drive safely, by alarming a failure of the vehicle responding to the judgment of the failure of a steering angle ratio sensor when a difference between a target steering ratio and an actual steering ratio is continued to be equal to or greater than a predetermined value for a predetermined period irrespective of a drive control signal equal to or greater than a predetermined value which has been output from the drive control means. SOLUTION: Failure detection means 14 defined by comparison means, a timer, a logic circuit, a memory and the like is provided with rate comparison means 25, time control means 26, output judgment means 27, and AND circuit 29. If the state where the drive control signal Mc equal to or greater than a predetermined value is output and the difference between the target steering ratio signal Cg and the actual steering ratio signal Gs is equal to or greater than a predetermined value is continued for a predetermined period, a failure signal As is output. The failure signal As is input to an alarm output means 28. When the failure signal As is at H level, the failure of the steering angle sensor 22 is alarmed. Responding to the alarm, the steering ratio is fixed, thus maintaining the appropriate steering.

摘要： PROBLEM TO BE SOLVED: To add an auxiliary torque to a steering system by forming an electric power steering device so that it can be switched over between a normal control mode in which the device is free from any defect and a failure mode in which an assist ratio is changed for the normal control mode when the device is under a specific failure. SOLUTION: An electronic control means 15 of an electric power steering device 1 in which a variable gear ratio mechanism is installed in a steering gear box 5 drives an electric motor 10 through an electric motor drive means with a torque signal detected by a steering torque sensor 12 and a control signal for electric motor control to provide a steering assist force according to a running condition. Also the electronic control means 15 is provided with a failure detector means and, when a failure is detected, the control mode is switched over between a normal control mode and a failure control mode according to the content of the failure. When the mode is switched over to the failure control mode, the assist ratio of a signal from the electric motor driving means to the electric motor 10 relative to a normal control mode is varied to inform an operator of a failure by giving a feeling as a steering feeling.

摘要： PROBLEM TO BE SOLVED: To detect abnormality in the operation of a current detecting part for detecting motor-current even during the travelling of a vehicle. SOLUTION: When a state where the deviation 27a of a target current IT from a motor-current IM detected by a current detecting part 26 exceeds a thrshold value, is continued for a specified time, the first judging part 31 outputs a first judging signal 31a. A forced driving control part 32 supplies a forced driving control signal 32b to a PWM signal generating part 36 through a switching part 37 to forcedly change the current supplied to an electric motor. When the fact that the motor-current is forcedly changed, is detected by a forced driving periodic signal 32a, and when the current IM detected at that time is not changed and the amount of the change is small to the extent that it can be judged to be detected current abnormality, a failure judging part 33 supplies a stopping command 33a to the PWM signal generating part 36 to stop the operation of the electric motor 10, and displays the abnormality on a display device 34.

摘要： PROBLEM TO BE SOLVED: To obtain a current detector having a function for judging a failure, and a motor controller having the current detector. SOLUTION: The potential at node N2 is controlled to equalize the potential VS at node N1 and a reference potential Vr and a control current i is fed from power supply potential VDD to the node N2. The control current i is fed to a Hall sensor 42e which delivers the output signal S42e of a potential proportional to the control current i and the flux density of field B. The output signal S42e is amplified by an operational amplifier 42f. The control current i is set by a resistor 42g. A judging section 42h makes a judgement whether the potential VS falls within a specified range or not. When the control current i is varied due to a failure of a component in a transistor 42d, for example, the potential VS deviates from the specified range for longer than a predetermined time. The judging section 42h makes a judgement that the component has failed and delivers a stop signal S42-2.

摘要： PROBLEM TO BE SOLVED: To drive a motor based on an estimated torque signal by providing a steering angle sensor for detecting a steering angle of a steering system and by having the steering torque sensor estimate a steering torque based on a steering angle signal and a car-speed signal at the time of failure. SOLUTION: A steering torque sensor 12 for detecting a manual torque and a steering angle sensor 18 for detecting a rotation angle of a steering shaft 3 are provided in a steering gear box. A controlling means 15 converts a steering torque signal T to a corresponding target current signal and issues a motor control signal V0 so as to drive a motor 10 through a motor driving means 16. The controlling means 15 determines that the steering torque sensor 12 fails when the steering torque signal T (T=0) is not put out regardless of output of a steering angle signal D, calculates an estimated torque amount corresponding to a car-speed signal V and the steering angle signal D, and controls the motor 10 based on this new steering torque signal T and the car-speed signal V.
