Problems solved by technology

However, because the first-gear clutch of this type of gearbox cannot slip, the driving force of the vehicle is prone to insufficient or even interrupted during the upshift process, resulting in large fluctuations in the acceleration and speed of the vehicle during the upshift process.

Abstract

The invention discloses a gear shifting control method and device of a hybrid power gearbox, a vehicle and electronic equipment. The gear shifting control method of the hybrid power gearbox comprisesthe following steps that when the vehicle meets the upshift condition, an upshift gear clutch is controlled to conduct sliding friction, the sliding friction torque is improved, a power source is controlled to improve the torque so as to keep the rotating speed of a current gear clutch, and when the value of the sliding friction torque of the upshift gear clutch is equal to the first torque threshold value, the power source is controlled to reduce the torque so that the current gear clutch can be disconnected; and when the rotating speed of the power source is reduced to the first rotating speed, the upshift gear clutch is controlled to be connected. As a result, the situations that the power is not interrupted in the upshift process, the speed and the acceleration of the whole vehicle arestable before the upshift operation is conducted and after the upshift operation is conducted, the smoothness of the whole vehicle is improved, and the upshift impact degree is reduced can be guaranteed.

Description

technical field [0001] The present invention relates to the field of vehicle technology, in particular to the field of hybrid transmission control, in particular to a hybrid transmission shift control method, device, vehicle, electronic equipment and computer-readable storage medium. Background technique [0002] At present, hybrid configurations at home and abroad are mainly divided into hybrid powertrains based on traditional gearboxes and new hybrid powertrains. The configuration of the hybrid powertrain based on the traditional gearbox is mainly modified on the basis of the traditional gearbox, and the structure and strategy of the gearbox have not changed much. Therefore, this type of configuration has weight, Arrangement and additional cost issues. The configuration of the new hybrid transmission assembly usually adopts an overall, system-based design method, which greatly reduces redundant parts and makes the hybrid power transmission system more compact, efficient a...
