Embodiment Construction

[0070] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0071] First, calibrate the position sensor of the motor. At this time, the assembled power assembly is placed on the trolley for the hot test of the engine. The two sets of cooling systems for the engine and the motor are assembled. At this time, use the calibration controller of the motor to start the engine, and the engine starts. Finally, the ISG motor exits to the idle mode, that is, the idle mode. When the engine speed is stable at about 800rpm, the MCU (motor controller) enters the calibration mode Alignmentmode. At this time, the Alignment calibration of the position sensor is realized through the zero point detection device and the algorithm in the MCU. And output the calibration quantity to PC through CAN. Before the hybrid controller HCU is installed in the vehicle, the calibr...

Abstract

The invention relates to a testing system of a hybrid power motor and a testing method thereof, wherein an engine, a motor and a power assembly of a gear box are assembled on the production line by one time; the power assembly is directed transported to a testing bench; firstly, the calibration of a motor position sensor is conducted; next, the reliability test of the motor is conducted; the testing system is provided with a calibration controller which conducts the calibration to the motor position sensor; the testing system also comprises a direct-current power cabinet, a PC computer, a three-phase converter box and a safety micro-control switch, wherein the phase a, the phase b and the phase c of the motor are connected with the calibration controller by the three-phase converter box; the calibration controller is electrified by the direct-current power cabinet and conducts communication with the PC computer by a CAN wire; the PC computer controls the power cabinet by a communication wire; simultaneously, the power cabinet can be controlled by a safety loop and the safety micro-control switch.

Description

technical field [0001] The invention relates to the field of reliability testing of a hybrid electric motor, in particular to a testing system and a testing method for a hybrid electric motor. Background technique [0002] The reliability test of the hybrid electric motor requires a huge bench and a dynamometer to assist in completing the test. The ISG (integrated starter generator) motor needs a control system, and the dynamometer also needs a control system, which is easy Causes the complexity of the control, and is extremely error-prone. After the reliability test of the ISG motor is completed, it is necessary to transport the powertrain to the production line again for assembly of the gearbox, which is unreasonable for logistics and the production line. [0003] At present, in the existing technology, the relevant technical materials include the patent document with the publication number CN200610054022.1. Its main structure is that after the engine and the ISG motor ar...
