Abstract:
A motor drive controller for a vehicle having an engine and a motor disposed therein as a vehicle-propulsion system, the motor having both driving and power-generating functions, comprising: an engine controller for controlling the running state of the engine; a motor controller for controlling both driving and power-generating states of the motor in a manner independent from the control over the engine performed by the engine controller; a vehicle velocity detector for detecting speed of said vehicle, along with an engine speed-detector for detecting revolutions of said engine; and an engine load-detector for detecting engine load; the motor controller including a map defined by respective detection signals from the vehicle velocity detector and the engine speed detector to determine the gear position; and the motor controller including a motor control map provided therein for each gear position, the map being defined by respective detection signals from the engine speed-detector and the engine load-detector, and wherein the motor controller is capable of searching out the motor control map corresponding to the gear position when calculating that position.
