    摘要: The present invention provides a protection apparatus in a control system for an electric vehicle which is capable of performing back-up driving by using a back-up control method, without using output from sensors even if the sensor in the control system for ordinary driving is failed. When at least one of the current sensor, the speed sensor and the accelerator sensor is detected to be abnormal, a back-up control voltage v1 is output as an abnormal signal from a running back-up control circuit. As a result, the running back-up control circuit sets the limiter of the output of the current control circuit to zero and switches the control signal to the inverter from vector control to V/f voltage control.

    摘要: In an electric vehicle drive controller, a drive controller has a controlling means which incorporates means for calculating a magnetic flux command from a basic torque command, for calculating a torque current command, exciting current command and slip frequency, and for operating vector calculation, and drives the motor. Voltage or power density of the power source is input to a correction coefficient calculating means and then input to a magnetic flux generating means by a correction coefficient to correct a magnetic flux. A magnetic flux generating means calculates the magnetic flux command by limiting and correcting the magnetic flux command according to the basic torque command and rotating speed, and determines a control variable for the magnetic flux command in correspondence to the motor rotating speed and torque command. By controlling the voltage to be applied to the motor in correspondence to the quantity of state of power source, it is possible to operate a drive unit on the most efficient point and reduce the size of electric power converter.

Both the current reference generator and the current control circuit are processed digitally by the same arithmetic unit.

    摘要: The invention provides an electric vehicle controller in which the generated motor torque is limited when the voltage of the vehicle battery decreases during running, in order to suppress over-discharge of the battery. A high torque can be obtained for a short period, however, even in the torque limiting period, and over-discharge is prevented by stopping electric power converting means in a final stage of discharge voltage of the battery. According to the invention, during operation of the vehicle, the battery terminal voltage is monitored and compared with a first comparison value V.sub.1. If the battery voltage falls below V.sub.1, a first counter commences measurement of the time period during which this condition continues. If the time period measured by the first counter reaches a preset value t.sub.1, torque limitation is initiated. In the torque limitation state, a torque command signal, generated by the control to operate the vehicle motor, is compared with the signal generated by the vehicle accelerator, and the signal having the lower value is thereafter used to control operation of the vehicle motor. In order to provide the capability to generate higher levels of torque for brief periods during torque limitation, the torque limitation process is terminated if the accelerator pedal is released completely.

    摘要翻译: 本发明提供了一种电动车辆控制器,其中当车辆电池的电压在行驶期间减小时,产生的电动机转矩受到限制,以便抑制电池的过度放电。 然而,即使在转矩限制期间也能够获得高扭矩,并且通过在电池的放电电压的最后阶段停止电力转换单元来防止过放电。 根据本发明,在车辆运行期间,监视电池端子电压并与第一比较值V1进行比较。 如果电池电压低于V1,则第一个计数器开始测量该条件持续的时间段。 如果由第一计数器测量的时间段达到预设值t1,则启动转矩限制。 在转矩限制状态下,通过车辆用电动机的操作控制产生的转矩指令信号与由车辆加速器产生的信号进行比较,然后使用具有较低值的信号来控制车辆电动机的动作。 为了在扭矩限制期间提供短时间产生更高水平的扭矩的能力,如果加速踏板被完全释放,转矩限制过程终止。
