Power assembly experimental apparatus for hybrid power automobile

Abstract

The disclosed experiment device for mixed-power vehicle power assembly comprises: a motor connected to the engine and clutch and the power supply through an inerter, a power analyzer connected to the detector, the supply and the sensor in motor loop to analyze collected different currents and record working state precisely; a cell management unit, a motor controller, and other controllers for motor, gear-box, and multi-energy, and a meter unit all connected to the detector by CAN bus.

Description

technical field [0001] The invention relates to automobile experiment technology, in particular to a hybrid electric vehicle powertrain experiment device Background technique [0002] Since a hybrid vehicle includes two power sources of an engine and an electric motor, multiple controllers such as an engine management unit, a multi-energy control unit, a motor controller, and a battery management unit have complex operating modes, which are very different from traditional vehicles. Therefore, it is necessary to test its various components, verify and debug its various functions. The traditional car has only one power source, and there is no power distribution problem. The experimental device is designed for the engine and is a mechanical drive route. Traditional testing scenarios cannot test for this. At the same time, in the acceleration, deceleration, starting and other working conditions of the hybrid vehicle, it involves the torque distribution of the engine and the mo...

AI Technical Summary

Problems solved by technology

The traditional car has only one power source, and there is no problem of power distribution. The experimental device is designed for the engine and is a mechanical drive route.

Traditional testing schemes cannot test for this

At the same time, in the acceleration, deceleration, starting and other working conditions of the hybrid vehicle, it involves the torque distribution of the engine and the motor, the magnitude of the current, etc., which cannot be tested by traditional experimental devices.
