VEHICLE LOSS MEASUREMENT DEVICE AND VEHICLE LOSS MEASUREMENT METHOD IN CHASSIS DYNAMOMETER

摘要

PROBLEM TO BE SOLVED: To provide a vehicle loss measurement device in a chassis dynamometer capable of measuring vehicle loss in consideration of acceleration and deceleration during exhaust gas fuel cost test mode operation.SOLUTION: A vehicle loss measurement device in a chassis dynamometer that performs various tests of a test vehicle 1 installed on a roller 2 includes a controller 10 that makes the chassis dynamometer a speed control mode and performs operation control with the vehicle speed pattern of an exhaust gas fuel cost test mode, and an operation unit 20 for subtracting loss of a single chassis dynamometer from mechanical loss detected by the load cell of the chassis dynamometer during operation in the exhaust gas fuel cost test mode to obtain the vehicle loss.SELECTED DRAWING: Figure 1
