Problems solved by technology

[0005] However, most of the mountain roads are rough and rough, which causes the slope of the mountain to change too quickly. Therefore, when the automatic transmission car goes uphill on the mountain, it is easy to change gears frequently, which will not only wear down the car gearbox but also reduce driving comfort.

Embodiment 1

[0041] Such as figure 1 As shown, the shift control method provided in this embodiment includes:

[0042] Obtain the slope value of the current vehicle driving position;

[0043] When the acquired slope value of the current vehicle driving position exceeds the slope value range corresponding to the gear mode of the current vehicle, and the acquired slope value of the current vehicle driving position corresponds to the same gear mode within a predetermined time, control the vehicle to shift Shift to the gear mode corresponding to the acquired slope value of the current vehicle driving position.

[0044]When the vehicle goes uphill on a road with a rapidly changing gradient, it is easy to return to the gradient value range corresponding to the driving mode immediately after the gradient value exceeds the gradient value range corresponding to the current vehicle driving mode. For the vehicle using the shift control method provided by the present invention, since the driving mod...

Embodiment 2

[0085] The shift control device provided in this embodiment applies the shift control method in Embodiment 1, such as Figure 4 As shown, the gear shift control device provided in this embodiment includes: a detection module 1, used to obtain the slope value of the current vehicle driving position when the car is going uphill; a control module 2, used to acquire the slope value of the current vehicle driving position When the value exceeds the slope value range corresponding to the gear mode of the current vehicle, and the slope value of the current vehicle driving position acquired within a predetermined time corresponds to the same gear mode, control the vehicle to shift gears to the acquired current vehicle driving position The gear mode corresponding to the slope value.

Abstract

The invention provides a gear shifting control method and device, and relates to the technical field of vehicle driving. The gear shifting control method comprises the steps that a gradient value of acurrent vehicle running position is obtained; and when the acquired gradient value of the current vehicle running position exceeds a gradient value range corresponding to a current vehicle gear mode,and when the gradient value of the current vehicle running position acquired within predetermined time corresponds to the same gear mode, a vehicle is controlled to be shifted to the gear mode corresponding to the acquired gradient value of the current vehicle running position. The gear shifting control device applies the gear shifting control method, and the device comprises a detection module and a control module. The method and device solve the technical problems that in the prior art, when automatic transmission vehicles go uphill, the gradient of a mountain changes too quickly, vehicle gearboxes are damaged due to frequent gear shifting, and the driving comfort is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle driving, in particular to a gear shift control method and device. Background technique [0002] Automatic transmission cars will enter different driving modes when driving under different road conditions. When the automatic transmission vehicle goes uphill on the mountain, in order to ensure that the automatic transmission vehicle has sufficient power, the automatic transmission vehicle will enter the mountain driving mode. [0003] The mountain driving mode has multiple gears, and different gears correspond to different slope value ranges. When an automatic transmission car goes uphill on a continuous mountain road with a large gradient change, the automatic transmission vehicle will shift gears as the slope changes. The driving force of the automatic transmission vehicle can be adjusted by shifting gears, so that the automatic transmission vehicle can maintain optimal power for a long time on ...
