ABSTRACT:
An simulated engine characteristic control system for transmission transient performance tests for automotive vehicles comprises a motor for driving an input shaft of the tested transmission, a pick-up for detecting revolution of the motor, a simulating circuit for simulating an opening angle of the throttle of the engine to be associated with the tested transmission or the intake manifold pressure of the engine, an engine characteristic generator for generating a torque command signal according to predetermined engine revolution/torque characteristic curves, in response to the signals from the pick-up and the simulating circuit, a torque/current transducer for transducing the torque command signal to an analog current command signal according to a predetermined torque/current characteristic, and means for compensating the current command signal in consideration of a torque component occurring at an axial moment of inertia of the rotating member of the motor during acceleration or deceleration of the motor, and a field characteristic of a field coil of the motor, representing the output torque/revolution of the motor. The motor is drivingly controlled in response to a current command signal compensated through the compensating means.
