Simulation engine rotating speed control method and device

Abstract

The invention provides a simulation engine rotating speed control method and device, and relates to the technical field of electric automobiles. The method is applied to the electric vehicle and comprises the steps that driving state information of the electric vehicle in the driving process is obtained; according to the driving state information, the comprehensive stress torque of the engine is determined; according to the comprehensive stress torque of the engine and the manual gear simulation gear, the output rotating speed of the engine is controlled; wherein the driving state information comprises at least one of the system state, the current rotating speed of an engine, the opening degree of an accelerator pedal, the state of the engine and the state of a clutch. According to the simulation engine rotating speed control method and device provided by the invention, the engine rotating speed can be simulated, the same experience that a driving school student has a manual-gear fuel vehicle after driving a modified electric vehicle is met, and the requirement of the driving school for an electric driving training vehicle is met.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for controlling the rotational speed of a simulated engine. Background technique [0002] With the widespread application of electric vehicles, many driving schools have also begun to use electric vehicles as training and driving test vehicles to ease their dependence on traditional fuel vehicles, reduce fossil fuel consumption and environmental pollution. In order to meet the needs of students to obtain a C1 driver's license, driving schools need to use manual transmission vehicles for training students, and the current single-stage deceleration electric vehicles cannot meet the needs of driving schools. Simulate the same working conditions. However, due to the fact that the engine speed of a manual fuel vehicle is related to many aspects such as driver operation and mechanical structure, many working conditions are difficult to accurately simulate...

AI Technical Summary

Problems solved by technology

In order to meet the needs of students to obtain a C1 driver's license, driving schools need to use manual transmission vehicles for student training, and the current single-stage deceleration electric vehicles cannot meet the needs of driving schools, so this type of electric vehicles needs to be benchmarked against manual transmission fuel vehicles Simulation transformation under the same working conditions

However, due to the fact that the engine speed of a manual transmission fuel vehicle is related to many aspects such as the driver's operation and mechanical structure, it is difficult to accurately simulate many working conditions through electric vehicles, such as engine stalling due to improper operation.
