Title:
ELECTRIC VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/075807
Kind Code:
A1
Abstract:
An electric vehicle control system is equipped with, as a driving source, a rotating electric motor controlled by a power conversion device and comprises: an electric motor control device (4) for outputting, according to a final torque command, a torque to the rotating electric motor (1); a torque calculation means (5) for, based on an operation mode for instructing an electric vehicle to move forward or backward and the speed of the rotating electric motor (1), calculating a torque command correction value for preventing the electric vehicle from moving in a direction opposite to the traveling direction indicated by the operation mode; and an adding means (6) for inputting an addition value to the electric motor control device (4) as a final torque command, said addition value being obtained by adding a torque command and the torque command correction value. This provides a control system applicable to various types of rotating electric motors without adding sensors for detecting the slope of a road surface and the weight of a vehicle and capable of maintaining the stop state of an electric vehicle without using a mechanical brake even on a sloping road.
