Title:
VEHICLE POWER ASSISTING SYSTEM
Document Type and Number:
Japanese Patent JP2020141529
Kind Code:
A
Abstract:
To provide a vehicle power assisting system which can reduce torque fluctuation resulting from speed irregularity which occurs in a motor generator which becomes an assisting power source, and operate a vehicle without applying excess current when the vehicle stops/starts a torque control function during travelling.SOLUTION: A vehicle power assisting system controls a motor generator for assisting vehicle travel. A control unit 105b of a power converter 105 which is provided between a DC power supply and the motor generator performs vector control. The control unit 105b does not have a function of non-interference control which is usually performed, and generates a voltage command value by using a signal equivalent to a signal which should be used as the non-interference control in start of current control.SELECTED DRAWING: Figure 2
