    摘要: A wheel stability control system for an electric vehicle including an electric motor, a drive inverter, and an electronic control unit (ECU) including a computer readable, non-transitory memory (memory) and an electronic processing unit (EPU). The memory stores information including an optimal acceleration and deceleration curve and the electrical characteristics of the electric motor. The EPU calculates the electrical moment of the electric motor from inputs from the drive inverter and the electrical characteristics of the electric motor. The ECU compares the electrical moment and the angular speed of the motor with the optimal acceleration and deceleration curve, and if the acceleration or deceleration of the electric motor is out of a predetermined range when compared to the optimal acceleration and the optimal deceleration, it reduces the electrical moment applied by the electric motor.

    摘要: A control device includes a PWM control unit that executes PWM control over an alternating-current motor mounted on a vehicle. The PWM control unit includes an alarm sound generation processing unit and a slip determination unit. The slip determination unit determines whether a drive wheel coupled to the alternating-current motor is slipping on the basis. of a d-axis current (Id), a q-axis current (Iq), a d-axis voltage command value (Vd) and a q-axis voltage command value (Vq) of the alternating-current motor. When the drive wheel is not slipping, the alarm sound generation processing unit generates an alarm sound from the alternating-current motor by adding a variation value (ΔV) to the d-axis voltage command value (Vd) at a predetermined interval. When the drive wheel is slipping, the alarm sound generation processing unit temporarily stops adding the variation value (ΔV) to the d-axis voltage command value (Vd).

    摘要: Provided is a controlling device for a railway electric car, the controlling device being able to detect a slipping/sliding phenomenon during, in particular, high-speed travel and to exercise slipping/sliding control in an appropriate manner. A slip controlling unit 1 includes a first adhesion level index generating unit and a second adhesion level index generating unit. In a normal slipping state in which an acceleration changes instantaneously, torque control is exercised by using a first adhesion level index generated by the first adhesion level index generating unit based on an acceleration deviation and a speed deviation. In a slipping state during high-speed travel, because the acceleration deviation and the speed deviation are small, torque control is exercised by using a second adhesion level index generated by multiplying the first adhesion level index by a gain equal to or smaller than 1 generated by the second adhesion level index generating unit.

    摘要: A method controls regenerative braking for a vehicle equipped with regenerative brakes and with a separate braking apparatus. The vehicle includes at least one first wheel and at least one second wheel. The separate braking apparatus is applied to the at least one first wheel and to the at least one second wheel. The regenerative brakes are applied to the at least one first wheel only. The method includes receiving a speed value of the first wheel and a speed value of the second wheel, estimating a value of a parameter representing a slip associated with the regenerative braking as a function of the speed value of the first wheel and as a function of the speed value of the second wheel, and forming a regenerative braking setpoint value as a function of the estimated value of the parameter representing slip associated with the regenerative braking.
