Embodiment Construction

[0015] The structure and principle of the EPS semi-automatic shift system of the present invention are as follows: figure 1 and figure 2 As shown, the mechanical gearbox 17 is the control body of the entire system, and the shift cylinder 16 and the gear selection cylinder 13 are fixedly installed on the casing of the gearbox 17 in an orthogonal manner. The gear shift cylinder 16 controls the gear shift fork in the gearbox 17 to realize gear shifting, and the gear selector cylinder 13 controls the gear selector shaft in the gearbox 17 to realize gear position selection, and the two coordinate motion to realize vehicle gear shifting. The shift position feedback unit 15 is installed on the shift cylinder 16, and the position sensing is realized by a Hall sensor group, which is used to feed back the position information of the piston in the shift cylinder 16, that is, to determine the position of the shift fork. The gear selection cylinder displacement sensor 14 is installed on ...

Abstract

The invention provides an EPS semi-automatic gear-shifting system. A clutch actuator is controlled to work through an electronic device between a handle manipulating assembly and a transmission so as to save part of mechanical mechanism connection, and an installing space is saved; on the premise that a gear transmission main tank is not changed, only a gear-selecting and gear-shifting actuator assembly is arranged outside a transmission upper cover, the actuator is controlled to work through a controller, and the goal of gear selection and gear shifting is achieved. Compared with traditional pure manual transmissions, according to the system, a clutch pedal can be trod and is not trod, and automatic separation and connection motion of a clutch is finished through a vehicle-mounted computer when the clutch pedal is not trod; due to the fact that electronic control and pneumatic execution are adopted, the EPS semi-automatic gear-shifting system can be simplified on the basis of an existing gear-shifting control system, gear-shifting control force is relieved, gear-shifting finish touch prompt is provided, and the gear-shifting response speed and gear accuracy are improved. Due to the fact that semi-automatic transmission control is adopted, the EPS semi-automatic gear-shifting system has the advantages of both a manual transmission and an automatic transmission, such as a fast pace in manual transmission driving and comfort and safety of the automatic transmission.

Description

technical field [0001] The invention relates to the technical field of automobile gear shifting, in particular to an electronically controlled semi-automatic shifting system. Background technique [0002] For the current traffic congestion in big cities, it is often necessary to stop and go during driving. For drivers who use manual transmission, they need to cooperate with their limbs to repeatedly shift gears, start, accelerator, and clutch cooperation. Cooperating with the handbrake to prevent the vehicle from slipping backwards, you will inevitably be in a hurry when you are in a hurry. It is really laborious and affects driving safety. And for rear-mounted gearbox vehicles, manual shifting is mostly done using a connecting rod or cable mechanism. Due to the long transmission distance, a large operating force is required, and accurate coordination of hands and feet is required to complete the shifting operation. Cause gearbox damage, serious traffic accidents. In shor...
