Problems solved by technology

However, the technology provided above cannot effectively solve the problems of clutch wear, engine oil consumption and pollution.
[0008] Based on the above-mentioned prior art, although there are a lot of technical inputs, how to reduce the wear of the clutch and the problems of fuel consumption and exhaust pollution caused by gear shifting cannot be specifically solved. Therefore, there is an urgent need for a gear shifter for hybrid vehicles. The gear shifting control method of the type gearbox, the engine shaft speed is controlled before the clutch is engaged, so as to achieve the synchronous state with the gearbox input shaft speed, so as to solve this problem

Abstract

A method for shifting gear of gear box on composite power vehicle utilizes motor to control combustion engine rotating speed for making it be synchronization to input shaft rotating speed of gear box to let clutch be engaged smoothly and quickly so as to decrease wear-out of clutch disc and reduce time of gear-shift when gear is shifted.

Description

technical field [0001] The present invention relates to a shifting control method of a gear-shift gearbox of a hybrid vehicle, in particular to a method for controlling the engine speed of an internal combustion engine by using an electric motor and a generator to achieve synchronization with the speed of an input shaft of a gearbox and to control the engine of an internal combustion engine The invention relates to a shifting control method of a gear-shifting gearbox of a compound power vehicle in which the output torque of an output shaft is zero. Background technique [0002] Please refer to Fig. 1 and shown in Fig. 2A, Fig. 1 is the schematic diagram of the power device of the shift control method of the shifting type gearbox of the hybrid vehicle of the present invention; Schematic diagram of the time relationship. The vertical axis in FIG. 2A represents rotational speed, and the horizontal axis represents time. Before the shift time point 20 , the gear of the gearbox ...
