摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of the operation feeling at the time of regenerative braking by gradually decreasing the current value by the regeneration of a travel motor as the vehicle speed is decreased during regenerative braking when the current value is adjusted at the time of regenerative braking of the travel motor to obtain the prescribed braking force. SOLUTION: In the regenerative braking mode, a regenerative contact C2 set to on in the normal travel mode is set to off, and a forward/reverse switching contact C3 is set to the fixed contact R side. A main switch element SW1 is turned on, and a regenerative exciting switch element SW2 is turned on. A current is fed to a field coil FC, and the self-power generating function by an armature AM is exerted. The SW2 is turned off, and the current self- generated by the armature AM is fed to the field coil FC. The SW1 is controlled by PWM based on the detected value of a current detector CT to obtain fixed braking force. When the vehicle speed is a prescribed value or below, the current value is gradually decreased.

摘要： PROBLEM TO BE SOLVED: To reduce the installation number of resistances of a battery vehicle. SOLUTION: In the state of contacts C1, C2 being closed and a contact C3 being closed to F (forward side) or R (reverse side), a main switching element SW1 is PWM-controlled to control a current flowing to a motor formed of an armature AM and a field coil FC, thus performing speed control. When a weak field contactor C4 is closed, a current flowing to the field coil FC is diverted to a flow dividing circuit formed of a common resistance r3 and the weak field contactor C4 so as to be able to perform field-weakening control. On the other hand, at the beginning of regenerative braking, when a regenerative exciting switching element SW2 is closed at the time of a regenerative contactor C2 being opened, a current flows along a path K13 (a path including the common resistance r3), so that self-power-generation of the motor is established, and regenerative braking can be performed even through the switching element SW2 is opened afterwards.
