CHASSIS DYNAMOMETER CONTROL SYSTEM AND ENGINE DYNAMOMETER CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce a response delay in the control of a motor with respect to a change in the speed or acceleration of an actual vehicle in a chassis dynamometer.;SOLUTION: A target torque calculating section 31 detects the speed or acceleration of the vehicle from the angular speed or angular acceleration of a motor 23 represented by a rotational speed signal V inputted from a dynamometer 2 and calculates a target value of the generated torque of the motor 23 for allowing a load in accordance with the detected speed or acceleration to act on a wheel. A correction value adding section 35 adds a correction value output by a correction value calculating section 32 to the target value and outputs the corrected target value to a feedback control section 36. The feedback control section 36 generates a control signal FBCNT so that the corrected target value matches a detected torque and performs feedback control for controlling the generated torque of the motor 23. When an engine vibration Seg is increasing, the correction value calculating section 32 presumes that a test vehicle 4 is being accelerated and calculates a positive correction value.;COPYRIGHT: (C)2009,JPO&INPIT
