Abstract

The invention discloses a manual gear fuel vehicle idle wobbling simulation method, system and device which are applied to an electric vehicle. Idle wobbling of a manual gear fuel vehicle is simulatedin a rotating speed control mode in the manner that the target rotating speed of the electric vehicle is subjected to wobbling adjustment. Compared with a motor torque control mode, the response speed is higher. Accordingly, the wobbling frequency and wobbling amplitude of the electric vehicle can be controlled well, and idle wobbling of the manual gear fuel vehicle can be simulated better. Thus,the electric vehicle, as a driving school vehicle, saves the fuel cost and reduces emission pollution. Moreover, the driving experience, namely, idle wobbling, of the manual gear fuel vehicle can besimulated better, and the driving habits of a traditional driving school fuel vehicle are maintained.

Description

technical field [0001] The invention relates to the field of new energy vehicle motor drive control, in particular to a simulation method, system and device for idling vibration of a manual transmission fuel vehicle. Background technique [0002] At present, the energy consumption efficiency of new energy vehicles is higher than that of fuel vehicles (especially pure electric vehicles). The engine efficiency of fuel vehicles is very low under low-speed and low-torque conditions, generally less than 20%, and the highest can only reach 35%. %; while the motor efficiency of electric vehicles can basically reach more than 70% under any working conditions, and the highest can reach about 96%. For school driving vehicles, most of the time they operate under low-speed and low-torque conditions. Therefore, the fuel consumption of traditional fuel-fueled school vehicles is relatively high due to low engine efficiency. However, using electric vehicles as school vehicles can save a lot...
