Abstract

An embodiment of the invention discloses an IBSG motor system stand and a test method and device. The rotating speed of a motor is controlled as a first preset value by a dynamometer, a target torqueof an IBSG is set, a present calculation torque of the IBSG motor is calculated in real time, the system stand obtains the practical output torque (actually measured torque) of the IBSG motor in realtime by means of a torque sensor, a host computer compares the actually measured torque with the target torque in real time to obtain a difference therebetween, when the difference is beyond a presetrange, a control parameter of the IBSG motor is adjusted so that the difference is within the present range, and when the control parameter is adjusted within the preset range, differences between every two of the present calculation torque, the actually measured torque and the target torque are calculate, and thus, the torque control precision and torque calculation precision of the IBSG motor inthe practical finished automobile operation condition can be evaluated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobile generators, and in particular to an IBSG starter-generator integrated motor system bench and a testing method and device. Background technique [0002] The IBSG (Intergrated Belt-driven Starter / Generator Integrated Belt-driven Starter / Generator) in existing automobiles is a motor with functions such as starting, power generation, electric power assist, and braking energy recovery. It can directly Installed at the position of the existing engine generator and connected to the engine crankshaft through a belt, the micro-hybrid drive system including the IBSG motor can achieve the purpose of energy saving and emission reduction. [0003] In the process of automobile research and design and development, it is necessary to have a full understanding of the performance of IBSG motors. The existing testing methods for IBSG motors are often based on individual tests of IBSG mot...
