Abstract

The invention relates to a vehicle gear shifting control method. A vehicle gear shifting control device comprises a knob type gear shifting machine, a gear shifting poking piece and a transmission control unit, wherein the three are all connected with a CAN bus, and exchange gear data; and the transmission control unit determines a sent gear actuation instruction according to gear request instructions of the knob type gear shifting machine and the gear shifting poking piece and a vehicle speed. Based on the knob type gear shifting machine, a control policy is more accurate, the entrance and the emigration of gears are more precise, and the whole vehicle operation performance is improved.

Description

technical field [0001] The invention relates to the field of mechanical control, in particular to a method for controlling gear shifting of a vehicle. Background technique [0002] Passenger car shifters can be divided into three types according to different control methods: push rod type zipper shifter, push rod type wire control shifter and knob type shifter. In recent years, push rod type wire control shifter and The knob-type shifter has gradually replaced the push-rod zipper shifter and is widely used. In the future, the knob-type shifter will gradually replace the former two and become widely popular. [0003] The knob-type shifter is generally composed of a lifting motor, an electromagnet, a transmission gear, a gear slot, a position sensor, a CAN transceiver, a motor drive chip, an electromagnet drive chip, a power conversion chip, and a control unit (MCU). The control unit (MCU) controls the lifting motor according to the presence or absence of the KL30 power and K...
