ABSTRACT:
In a vehicle driveability evaluation system, an engine is coupled to a dynamic dynamometer which is capable of changing a load torque and a speed in a very short time. A control unit controls the dynamic dynamometer so that the load torque and the speed of the dynamometer simulate the load and the speed of the engine when it is mounted on an actual vehicle. The driveability evaluation test is performed by operating the engine while simulating various running conditions of the vehicle by the dynamic dynamometer. Engine operating parameters such as an engine speed and an output torque are converted by a driveability data generating unit into driveability data such as an acceleration and vibration of the vehicle in accordance with the characteristic of the vehicle. These driveability data are converted by a sense-data generating unit into stimuli such as visual images, sounds and forces which can be directly perceived by the human senses. Therefore, an inspector can directly perceive the driveability of the actual vehicle from the stimuli generated by the sense-data generating unit without actually mounting the engine in the vehicle body.
