Abstract

The invention relates to a gear shifting control method and device of a manual transmission type vehicle and a gear shifting control system of the manual transmission type vehicle. The gear shifting control method comprises the steps that bottom dead center signals of a clutch are obtained; according to bottom dead center signals of the clutch, whether the clutch is located at the bottom dead center or not is judged; and if the judgment result is yes, the rotation speed of an engine is controlled to be synchronous with the rotation speed of an input shaft of a transmission. By the adoption of the technical scheme, the impact in the gear shifting process can be eliminated, the burden of a driver can be lightened, and the driving experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method, device and control system for shift control of a manual transmission vehicle. Background technique [0002] At present, when a manual transmission vehicle shifts gears, the engine speed and the speed of the transmission input shaft are generally synchronized through the slipping of the clutch plate. This requires the driver to control the clutch pedal. Slightly faster, it is easy to cause shock. [0003] For example, in the process of upshifting, before the clutch is released, the engine speed is higher than the input shaft speed of the transmission, and the quick release of the clutch will cause an impact; In the process of downshifting, before the clutch is released, the engine speed is lower than the speed of the transmission input shaft, and the quick release of the clutch will cause an impact; shock. Contents of the invention [0004] Based on this, it is nec...
