Abstract

The invention belongs to the automotive automatic gear change electric control field, and particularly relates to an automotive AMT automatic gear change electric control system. By the adoption of the automotive AMT automatic gear change electric control system, an existing MT automobile can be transformed to be an automobile provided with an AMT electric control system. The automotive AMT automatic gear change electric control system is also suitable for small-displacement automobiles. By the adoption of the automotive AMT automatic gear change electric control system, precise operation is achieved, energy is saved, and oil consumption can be reduced by 3-5% compared with MT and over 20% compared with AT; multiple computers are adopted for control, the actual gear change condition of an engine can be automatically matched, impact on the engine and a driver caused by misoperation can be avoided, and the service life of the whole automobile is prolonged; a driver only needs to step on the gas to start and drive the automobile, the requirement for the driving skill of the driver is reduced, and working intensity is relieved; most importantly, an original engine is only transformed slightly, maintenance is convenient, and maintenance cost is low.

Description

technical field [0001] The invention belongs to the field of electric control for automatic shifting of automobiles, and in particular relates to an electric control system for automatic shifting of automobiles AMT. Background technique [0002] Automotive electromechanical automatic transmission (AMT) is an automatic transmission system controlled by a microcomputer on the basis of a dry clutch and a gear transmission. It can determine the best gear according to parameters such as vehicle speed, accelerator, and driver's command, and control the clutch separation and engagement, the shift handle's removal and engagement of the gear lever, and the synchronous adjustment of the engine's throttle opening that were originally completed manually by the driver. Wait for the operation process, and finally realize the manipulation automation of the shifting process. Due to the limitation of motor control technology, the existing automatic transmission system (AT) of automobiles ca...
