Abstract
PURPOSE: To prevent the decrease in the total braking force at the time of electro- pneumatic switching of the subject electric vehicle by a method wherein a voltage command value is obtained by subtracting the output of the limitter circuit in proportion to the amount exceeding the prescribed value of the constant current controlling system output from the output of the pattern generating circuit of the motor current.
CONSTITUTION: A brake current pattern 13 is outputted from a signal equivalent- to-brake-force 10 and a signal equivalent-to-load 11 of a current pattern generating circuit 12. At the time of regenerative braking, a limitter 21 functions when the speed is decreased and the current passing coefficient γ of the chopper 6 is expanded to a current passing coefficient γo as specified by the current passing coefficient 20, and said output is inputted to a subtracter 15 through the "ON" of a switch circuit 23, the prescribed brake current pattern 13 is subtracted, a brake current-limit value pattern 16 is reduced, and the motor current is reduced in proportion to the above through the output 19 (corresponding to the current continuity rate γ) of the comparison amplifier circuit 18 having a motor current signal 17 which will be used as one of inputs. The reduced speed of the motor current is to be adjusted in such a manner that the air brake can respond sufficiently.
