Method for control torque of electric vehicle by simulating manual gear fuel vehicle

Abstract

The invention provides a method for control the torque of an electric vehicle by simulating a manual gear fuel vehicle, belonging to the field of electric vehicles. The method includes the steps: installing a simulated clutch, a simulated gear, a torque controller and an engine sound simulator on a single-stage deceleration electric vehicle; obtaining a clutch pedal position, a gear lever gear position, a vehicle speed, an accelerator pedal position and a brake pedal position, and calculating a corresponding engine simulation speed under the current state; emitting engine simulation noise withcorresponding sound and frequency by the engine sound simulator according to the calculated engine simulation speed; and according to the obtained engine simulation speed and accelerator pedal position, controls the vehicle drive torque by the torque controller to obtain the output torque of the drive motor under different operating conditions. The method for control the torque of an electric vehicle by simulating a manual gear fuel vehicle adopts the method of installing the clutch simulator and the gear simulator to maximally simulate the torque output strategy of a traditional fuel manualgear vehicle and realize the functions of simulating engine braking, vehicle jitter, idle speed and the like.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a torque control method for an electric vehicle simulating a manual transmission fuel vehicle. Background technique [0002] As a "green means of transportation", electric vehicles have the characteristics of no pollution, low noise and low energy consumption compared with ordinary internal combustion engine fuel vehicles. At present, the transmission system of electric vehicles mostly adopts a single-stage or two-stage reducer scheme. Without the multi-speed manual transmission on the transmission fuel vehicle, the manual shifting function cannot be realized. In order to meet the driving habits of some consumers with manual transmission and the needs of driving school students to obtain a manual transmission driver's license, OEMs must develop electric vehicles with manual transmission function. At present, in response to this demand, the common practice is to direc...

Problems solved by technology

At present, in response to this demand, the common practice is to directly replace the single-stage or two-stage reducer with a common clutch and a multi-speed transmission, but the working characteristics of the drive motor are different from those of the traditional gasoline engine, with fast torque response, etc. Features, it is very easy to cause the clutch to burn out, and it is expensive to replace the clutch and the multi-speed gearbox. The clutch and the multi-speed gearbox are easy-wearing parts, and the later maintenance costs are high
