    摘要： A battery power monitoring apparatus for use in an electric automobile is provided. The battery power monitoring apparatus determines the amount of available reserve electric power remaining in a storage battery based on electric power discharged from the storage battery to an electric motor and a battery characteristic stored in a memory, representing a relation between a voltage level at which a given level of current flows from the storage battery and the then discharged electric power. The battery characteristic is updated based on the latest detected voltage of the storage battery and current flowing from the storage battery. The battery power monitoring apparatus determines that charge polarization has occurred when a voltage level of the storage battery from which the given level of current flows is increased, and prohibits the updating of the battery characteristic. With this operation, the amount of available electric power is calculated correctly even under the influence of charge polarization.

    摘要： A braking force control system of an electric vehicle includes a regenerative-controllable motor for driving driven wheels, wheel cylinders for braking non-driven wheels, respectively, and a master cylinder connected to a brake pedal for producing a master cylinder pressure in proportion to a depression amount of the brake pedal. A mechanical braking force control unit is further provided in a working fluid passage from the master cylinder and the wheel cylinders. The mechanical braking force control unit includes a proportioning valve and a free-piston cylinder arranged in parallel with each other in the working fluid passage. The proportioning valve is operated to output a wheel cylinder pressure to the wheel cylinders when the depression amount of the brake pedal is no more than a given value. On the other hand, the free-piston cylinder is operated to output a wheel cylinder pressure to the wheel cylinders when the depression amount of the brake pedal is more than the given value. A motor control unit is further provided to perform a regenerative control of the motor for achieving a regenerative braking force which is equal to a difference between a target total braking force derived based on the depression amount of the brake pedal and a mechanical braking force derived based on the wheel cylinder pressure outputted from the mechanical braking force control unit.

    摘要： In order to keep the braking torque of a motor always maximal and to execute suitable ABS regenerative braking, a controller of an electric car has a motor (1) connected to the road wheels, and its central controller confirms that regenerative energy calculated from output signals from an ammeter (51) and from a volt meter (52) after the braking operation begins reaches a maximum value, and stores a braking torque calculation value obtained from a signal from a motor number-of-revolution sensor (63), as a maximum braking torque value. When the difference between the braking torque command value applied to the motor (1) and the braking torque calculation value exists within a predetermined range, the braking torque command value is thereafter increased or decreased in accordance with the difference between the maximum braking torque value described above and a present braking torque calculation value, and when the difference is out of this predetermined range, the braking torque command value is decreased.

    摘要： A rotary actuator has a synchronous motor and an internally meshing planetary reduction gear having a first shaft rotated by the synchronous motor, an outer gear mounted to said first shaft with an eccentric part so as to be eccentrically rotatable around said first shaft, an inner gear with which said outer gear meshes internally, and a second shaft connected to said outer gear with a transmission means that only transmits said outer gear rotation on its axis to the second shaft. The synchronous motor and the internally meshing planetary reduction gear are accommodated inside a housing, and the first shaft doubles as a rotor shaft of the synchronous motor. An incremental encoder provided along a rotary shaft of the synchronous motor detects the rotation angle of a rotor of the synchronous motor.
