摘要： When a braking/driving force on each wheel is used for vehicle motion control, in order to reduce a noise generated by a zero cross of a motor torque, provided is a distribution setting part, which is to be applied to a vehicle configured so that a conversion rate of converting a braking/driving force on the wheel into a force in a vertical direction of a body by a suspension is different between a front wheel side and a rear wheel side. The distribution setting part sets distributions of a driver-requested driving force to front/rear wheels so as to be larger to the wheels coupled to the suspensions smaller in conversion rate than to the wheels coupled to the suspensions larger in conversion rate. As a result, a zero cross of a motor torque is restrained, resulting in a reduction in generation of a noise caused by a backlash of speed reduction gears.

摘要： In a steering apparatus, a differential lock mechanism has a lock holder in which a plurality of groove portions are formed on an outer periphery thereof, and selectively allows and prohibits to generate a difference of steering amount in the rotational direction between an input shaft and an output shaft by selectively engaging and disengaging an engaging portion with respect to the groove portions. A rotation sensor detects the position in the rotational direction of the lock holder during one rotation of the lock holder and repeatedly detects the same sensor pattern being output a plurality of times. A variable transfer ratio unit ECU detects which groove portion, from among the plurality of groove portions, the engaging portion is engaged with using the sensor pattern output by the rotation sensor when a side portion of one of the groove portions is pressing against a side portion of the engaging portion.

摘要： An electronic control unit of a braking force control apparatus for a vehicle activates, as a first state, in-wheel motors in a regeneration state, thereby generating motor braking torques, and causes friction brake mechanisms to generate friction braking forces. Moreover, the unit activates, as a second state, the motors in a power running state, thereby generating motor driving torques, and causes the mechanisms to generate friction braking forces. Then, when the state is caused to transition between the first state and the second state, the unit changes magnitudes of the braking torques or the driving torques generated by the motors to one of increase and decrease, and changes magnitudes of the friction braking forces generated by the mechanisms to one of increase and decrease.

摘要： In a steering device (200), a first motor (34a) operates in accordance with a steering operation of a steering handle (12), a first steering shaft (52) steers one of the pair of wheels (58), and a first conversion unit converts a rotation of a first rotor (31a) as a rotation element of the first motor (31a) into an axial-direction movement of the first steering shaft (52). A second motor (34b) operates in accordance with the steering operation of the steering handle (12), a second steering shaft (53) is separated from the first steering shaft (52) and steers the other of the pair of wheels (58), and a second conversion unit converts a rotation of a second rotor (31b) as a rotation element of the second motor (34b) into an axial-direction movement of the second steering shaft (53). A coupling unit (60) couples the first rotor (31a) and the second rotor (31b) together and cancels the coupling of the first rotor (31a) and the second rotor (31b).

摘要： An electric steering control device is provided which is capable of enabling the driver to perform steering manipulation stably without being substantially affected by the ambient temperature and the heat generation of the control device. The control device comprises a temperature sensor for detecting the temperature of a circuit board mounting a motor drive circuit thereon and a compensation section for compensating an electric current command value based on the board temperature detected by the temperature sensor, so that en electric motor for exerting an assist force on a vehicle steering mechanism is driven by the compensated electric current command value output from a motor drive circuit. Therefore, the steering operation can be done stably without being substantially affected by the ambient temperature and the heat generation of the control device. In particular, since the temperature sensor is arranged not on the motor drive circuit per se but on a circuit board mounting the motor drive circuit thereon, the freedom can be heightened in arranging the temperature sensor. Further, since the temperature sensor for heat control of a spiral cable provided on the electric motor is utilized also for compensation of the electric current command value, the components for the control device can be reduced in number.
摘要翻译：提供一种电动转向控制装置，其能够使驾驶员能够稳定地执行转向操作，而不受基本上受到环境温度和控制装置的发热的影响。控制装置包括温度传感器，用于检测在其上安装电动机驱动电路的电路板的温度，以及补偿部分，用于基于由温度传感器检测到的电路板温度补偿电流指令值，使得用于施加电动机由电机驱动电路输出的补偿电流指令值驱动车辆转向机构上的辅助力。因此，可以在不受环境温度和控制装置的发热的显着影响的情况下稳定地进行转向操作。特别地，由于温度传感器本身不设置在电动机驱动电路上，而是在其上安装电动机驱动电路的电路板上，因此可以在布置温度传感器时提高自由度。此外，由于设置在电动机上的螺旋形电缆的热控温度传感器也用于电流指令值的补偿，所以可以减少控制装置的部件数量。
