Problems solved by technology

[0002] Automatic transmission vehicles are favored by people because of their comfortable and convenient driving. As an important part, the shift lever of automatic transmission is associated with the body control system, and the existing shift controller generally uses a lever for mechanical shifting. The impact is large, it is easy to cause damage to the gearbox, and there are problems of low shift efficiency, low labor intensity and poor comfort
Moreover, in the process of driving the car, once the human error is operated, it will cause damage to the gearbox.

Abstract

The invention discloses a gear shifting control system. The gear shifting control system comprises a gear shifting controller, a gear shifting handle, a gear shifting actuating mechanism and a transmission controller, wherein a photoelectric tube array device is arranged at the lower end of the gear shifting handle and acquires handle operation information of a user; the gear shifting actuating mechanism receives control signals transmitted from the gear shifting controller and drives a motor to rotate so that make and break of an inner oil line of a transmission are controlled; the gear shifting actuating mechanism also drives a transmission gear sensor to rotate; the transmission controller acquires current position information fed back by the transmission gear sensor in time, and transmits the current position information to the gear shifting controller and a combination instrument in a CAN (controller area network) bus message mode; and after receiving gear feedback information, the transmission controller drives an electromagnetic valve in the transmission to control a gear to perform gear shifting. Operation of the user is converted into electric signals capable of expressing operation intention of the user, the electric signals are forwarded to a transmission control unit (TCU), and the transmission control unit directly drives the transmission to carry out gear shifting.

Description

Technical field [0001] The invention relates to the field of automobiles, in particular to a shift control system. Background technique [0002] Automatic transmission cars are favored by people because of their comfortable and convenient driving. As an important component, the automatic transmission shift lever is associated with the body control system, and the existing shift controller generally uses the shift lever for mechanical shifting. The impact is large, it is easy to cause damage to the gearbox, and there are problems of low shifting efficiency, low labor intensity and poor comfort. Moreover, during the driving process of the car, once human misoperation, it will cause damage to the gearbox. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a shift control system, which does not directly operate the gearbox, but converts the user's operation into an electrical signal that can express the user's operation intenti...
