Control of Drive-Train Bench System for Simulating the Real Vehicle Motion
نویسندگان
چکیده
Drive-train bench system is utilized to test powertrain components of a vehicle such as transmission, torque converter, etc. In order to simulate the real vehicle motion, it is necessary that dynamometers of the drive-train bench simulates the various road conditions such as dry road surface and snow road surface, etc. To simulate the condition that the vehicle is running on the dry road, it is necessary that the dynamometer is controlled so that the moment of inertia of the output side of the drive-train bench is virtually equal to the moment of inertia of the vehicle. On the other hand, to simulate the snow road surface, it is necessary that the dynamometer is controlled so that the moment of inertia of the drive-train bench is virtually equal to the moment of inertia of the tire. Furthermore, in the brake operation on the snow road surface, braking time changes by how to use brake. Drive-train bench simulates the brake operation of real vehicle by controlling the dynamometer. In this paper, a control design method of the drive-train bench system is proposed for simulating various road conditions and brake operation.
