Abstract
The present invention provides 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 a running state of the engine; motor controller for controlling both driving and power-generating states of the motor in a manner independent of control over the engine taken by the engine controller; vehicle velocity-detector for detecting the speed of the vehicle and engine speed-detector for detecting revolutions of the engine; and engine load-detector for detecting an engine load. The motor controller includes a map defined by respective detection signals from the vehicle velocity-detector and the engine speed-detector, enabling gear position to be calculated.
