Problems solved by technology

In order to ensure the comfort of gear shifting at low speeds, the 1st gear and 2nd gear clutches will be frequently engaged and disengaged, which will inevitably cause excessive slipping of the 1st gear and 2nd gear clutches, and in the case of frequent shifting up and down for a long time, It also reduces the life of the clutch
If the control is not good, it may cause the clutch plate to burn and the oil to deteriorate, so that the entire hydraulic control system has a risk of failure

Abstract

The invention discloses a method for controlling gear shifting of a vehicle. The method comprises the first step of detecting the times of the gear shifting and gear positions of the vehicle in first preset time, the second step of judging whether the vehicle enters a road jamming control mode or not according to the times of the gear shifting and the gear positions, the third step of controlling gears of the vehicle to be shifted from the current gear to a neutral gear or from the neutral gear to a preset gear when the vehicle enters the road jamming control mode. By means of the method, frequent gear shifting between a first gear and a second gear under the jamming city road situation is avoided, gear shifting pause brought by frequent gear shifting is avoided, meanwhile, excessive friction, between a first gear clutch and a second gear clutch, brought by the frequent gear shifting is eliminated, the service life of the clutches is prolonged, and the risks that the first gear clutch and the second gear clutch are burned are reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a control method for shifting gears of a vehicle. Background technique [0002] With the increase of the number of cars, the urban road conditions are becoming more and more congested. Under the congested urban road conditions, when the cars stop and go, the automatic transmission will frequently start from 1st gear to 2nd gear, and then down from 2nd gear to 1st gear. In order to ensure the comfort of gear shifting at low speeds, the 1st gear and 2nd gear clutches will be frequently engaged and disengaged, which will inevitably cause excessive slipping of the 1st gear and 2nd gear clutches, and in the case of frequent shifting up and down for a long time, It also reduces the life of the clutch. If the control is not good, it may cause the clutch plate to be burned and the oil to deteriorate, so that the entire hydraulic control system has a risk of failure. Contents of the i...
