Description

technical field [0001] The invention relates to a vehicle simulation experiment equipment and a simulation experiment method thereof, in particular to a device and a method for simulating a vehicle speed output by a drive train in a vehicle simulation experiment. Background technique [0002] In the existing vehicle simulation equipment, it includes engine simulation module, vehicle engine control module and vehicle speed generation module. In the experimental equipment, the vehicle engine control module receives information such as the engine speed from the engine simulation module and the vehicle speed signal from the vehicle speed generation module to control and adjust parameters such as fuel injection that control the engine simulation module.

AI Technical Summary

Problems solved by technology

However, the vehicle speed output mode is controlled by an open-loop module, that is to say, the output of the vehicle speed is adjusted separately through the knob of the vehicle speed generation module, and is not related to the engine simulation speed in the engine simulation module.

In addition, the existing vehicle speed output module can also be a vehicle speed output module with a fixed transmission ratio, which can realize the vehicle speed output in a single ratio to the engine speed, but does not consider the gear position of the transmission of the vehicle's drive train on the vehicle speed. Impact

As a result, the existing vehicle simulation experiment equipment and its simulation methods cannot realize the actual vehicle operating conditions, and some simulation tests cannot be realized.
