Control device and operation method for gear shifting of manual gearbox without stepping on clutch and loosening accelerator

Abstract

The invention discloses a control device and an operation method for gear shifting of a manual gearbox without stepping on a clutch and loosening an accelerator. The control device comprises a user operation and prompt interface, a communication interface of a vehicle and an engine, and a gear shifting control calculation processing unit, wherein the user operation and prompt interface comprises an up-shift key, a down-shift key, a neutral gear key and a voice prompt module; the communication interface of the vehicle and the engine is in data connection with the user operation and prompt interface; the communication interface of the vehicle and the engine obtains data information of the engine rotating speed, the vehicle speed, the current gear of the vehicle, the neutral gear state, the clutch state and the brake state through a CAN message; the gear shifting control calculation processing unit is in data connection with the user operation and prompt interface and the communication interface of the vehicle and the engine, and is used for calculating the synchronous rotating speed of the engine and the gearbox in real time according to the data information acquired by the communication interface of the vehicle and the engine; and the synchronous rotating speed is used for realizing gear shifting of the manual gearbox without stepping on the clutch. By means of the control device provided by the invention, the gear shifting mode of the manual gearbox without stepping on the clutch and loosening the accelerator can be achieved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control device and an operation method for a manual transmission of a commercial vehicle with manual shifting without stepping on the clutch. Background technique [0002] For a vehicle with a manual transmission, you must release the accelerator and step on the clutch before performing the shift operation. After the shift operation is completed, release the clutch and step on the accelerator to continue driving. The operation is relatively cumbersome, especially in urban conditions. Stepping on the clutch and shifting gears will consume a lot of physical strength and energy of the driver, causing driving fatigue and emotional irritability, and even affecting driving safety. [0003] At present, most passenger car models have adopted automatic transmissions, and their types mainly include hydraulic automatic transmissions (AT), mechanical continuously variable automatic transmissions...

AI Technical Summary

Problems solved by technology

[0006] 1. You must release the accelerator and step on the clutch before performing the shift operation. After the shift operation is completed, release the clutch and step on the accelerator to continue driving. The operation is cumbersome, especially in urban working conditions. Consume a lot of physical strength and energy of the driver, cause driving fatigue and emotional irritability, and even affect driving safety

[0007] 2. For vehicles with manual transmissions that have been sold, due to the huge difference in the structure of the drive train, it is almost impossible to refit them into automatic transmissions, and such refitting is not allowed in laws and regulations
