The invention discloses a hardware-in-the-loop (HIL) detection system for a hybrid electric vehicle, which comprises an HIL device, a load and a temperature and humidity-adjustable environmental box, wherein the HIL device sequentially comprises steps of functional design and off-line simulation, rapid control prototype (RCP) development, target code generation, HIL simulation, functional design and off-line simulation and verification; the load is a relay connected with a programmable power supply; the temperature and humidity-adjustable environmental box is internally provided with a temperature sensor, a humidity sensor and temperature and humidity HIL equipment, the temperature sensor and the humidity sensor are connected with a to-be-detected hybrid electric vehicle model controller, and the hybrid electric vehicle model controller comprises a vehicle model and a control model. Through simulating the real hybrid electric vehicle use environment, the test reliability is improved, and important reference data are provided for improving the hybrid electric vehicle reliability.
Description
technical field [0001] The invention relates to the technical field of hybrid electric vehicle testing, in particular to a hardware-in-the-loop detection system for hybrid electric vehicles. Background technique [0002] With the rapid development of automobiles, the requirements for the overall performance and reliability of the vehicle powertrain are getting higher and higher. In order to ensure the safety, reliability, and durability of the automotive powertrain after development and design, key components and controllers must be tested successively through model-in-the-loop testing (MIL), software-in-the-loop testing (SIL), and hardware-in-the-loop testing (HIL). Bench test, real vehicle test these links. In order to ensure product quality while shortening the product design cycle and reducing R&D costs, HIL testing is an integral part of the control system design and development cycle. Only controllers that perform well during the HIL test phase can proceed to the nex...
