Simulation Test Solution for Powertrain System
Overview
Nowadays,although new energy electric drive technology is developing rapidly, 48 V and other hybrid system, traditional commercial vehicles, and special industries such as motorcycle, agricultural machinery, and construction machinery are still widely using of engine and transmission technology. In these technical fields, it is still very necessary to have independent development, testing and verification capabilities for engines and transmissions.Hirain has more than ten years of experience in the development of HIL simulation equipment for powertrain system, and can provide users with complete simulation test solutions.
