20080272582 | ENERGY ABSORBING STEERING SYSTEM - In an energy absorbing steering system including a steering shaft to which a steering member is coupled, and a steering column that rotatably supports the steering shaft, at least one of the steering shaft and the steering column includes an impact absorbing portion that contracts when a load equal to or higher than a predetermined value is applied, and the impact absorbing portion includes a first impact absorbing portion having a first impact absorption load, and a second impact absorbing portion having a second impact absorption load different from the first impact absorption load. | 11-06-2008 |
20080277193 | ELECTRIC POWER STEERING DEVICE - A steering shaft is composed of an upper shaft, a lower shaft, an input shaft, and an output shaft. The upper shaft, the lower shaft, and the input shaft can rotate together, and the input shaft and the output shaft are relatively rotatably coupled to each other via a torsion bar. The rotational position of a rotor coupled to the output shaft is calculated based on the detected rotational position of the lower shaft and a steering torque detected based on the amount of relative rotational displacement of the input shaft and the output shaft. Thus, it is not necessary to include a rotor rotational position detecting unit for detecting the rotational position of the rotor within the electric motor, which reduces the size of the electric motor. | 11-13-2008 |
20090079373 | MOTOR CONTROLLER AND ELECTRIC POWER STEERING SYSTEM - A current sensor of a motor controller detects the current applied to a motor drive circuit and thus a phase where a failure cannot be detected would occur without taking any measures. However, an abnormal current monitor section contained in a microcomputer receives a voltage signal of an average value of the currents detected in the current sensor by allowing a signal to pass through a first LPF having a cutoff frequency sufficiently lower than the frequency of a PWM signal. Therefore, whether or not the value is within a predetermined normal range is checked, whereby whether or not some failure containing a failure of the current sensor occurs can be easily determined about every phase. | 03-26-2009 |
20120090913 | ELECTRIC POWER STEERING SYSTEM - A controller applies slight rotational torque to a drive gear of a reduction mechanism also in a predetermined range in which a motor does not produce any steering operation assist force. That is, the motor is caused to produce slight rotational torque not enough to drive a driven gear, and the rotational torque direction is reversed under a given condition. Accordingly, a backlash between the drive gear and the driven gear is eliminated. | 04-19-2012 |
