Abstract
PURPOSE: To prevent the slip of tires at quick acceleration by quickening the rise up of an accelerator command voltage upto a certain value by the conducting-rate detection in soft start characteristics, then, giving the linear delay characteristic.
CONSTITUTION: When the accelerator 17 is fully opened in the starting on the flat ground, the chopper conducting rate (the conducting rate at which the car starts) is detected, a transistor TR3 is in the conductive state during the time the output of an operation amplifier 26 is Low, and the voltage of a capacitor C1 rises up quickly. Thereafter, the conductive rate increases, the output of the amplifier 26 becomes H, the transistor TR3 becomes nonconductive, and the first delay characteristic is obtained with the time constant formed by resistors R1 and R2 and capacitor C1. Therefore, the accelerator command current Ic flowing in the acceleration command winding 22 varies similarly. The output waveform of a magnetic phase shifter varies depending on the increase in the current Ic, a chopper circuit 14 repeats the conduction and nonconduction by a trigger circuit 24, the average voltage to be applied to the motor is varied, thereby the motor speed is conrolled.
