Abstract

The embodiment of the invention discloses a vehicle model, a vehicle simulation system and a vehicle. The vehicle model comprises a mechanical automatic gearbox actuator signal processing sub-model, a whole vehicle physical sub-model, a mechanical automatic gearbox sensor signal processing sub-model and a bus communication sub-model. Wherein the sensor signals comprise a gearbox air pressure sensor signal and a gearbox oil temperature sensor signal. According to the embodiment of the invention, testing is carried out through the virtual automobile model, and real automobile testing is not needed. Therefore, the development cost can be saved, the development period can be shortened, various working conditions including the limit working condition can be reproduced, and the test working conditions are rich. Sensor signals comprise a gearbox air pressure sensor signal and a gearbox oil temperature sensor signal. Therefore, the possibility is provided for the control performance test of the mechanical automatic gearbox.

Description

technical field [0001] Embodiments of the present invention relate to vehicle development and testing technologies, and in particular, to a vehicle model, a vehicle simulation system and a vehicle. Background technique [0002] The automatic mechanical transmission (AMT) of automobiles involves multidisciplinary fields such as machinery, pneumatics, electronics and control, and its working conditions are very complex and require extremely high safety. Unit) design complexity. [0003] In the software development process of the AMT controller, especially before the software is mass-produced, it is essential to test the application layer software, the underlying software and the hardware. At present, this kind of test is generally a road test after the actual vehicle is equipped with an AMT controller, which is time-consuming and labor-intensive, increases the development cost, and lengthens the development cycle. And some extreme working conditions are difficult to reproduc...
