Shift control method, device, vehicle and electronic device for hybrid transmission

Abstract

The invention discloses a shift control method, device, vehicle and electronic equipment of a hybrid transmission. The shift control method of the hybrid transmission includes the following steps: when the vehicle meets the upshift condition, controlling the upshift clutch to perform slippage, increasing the slipping torque, and controlling the power source to increase the torque to maintain the current gear clutch. speed; when the slip torque of the upshift gear clutch reaches the first torque threshold, the power source is controlled to reduce the torque to disengage the current gear clutch; when the speed of the power source is reduced to the first speed When , the upshift clutch is controlled to be engaged. Therefore, it can be ensured that the power is not interrupted during the upshift, the speed and acceleration of the entire vehicle are stable before and after the upshift, the ride comfort of the entire vehicle is increased, and the upshift shock is reduced.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to the field of hybrid transmission control, and in particular to a method, device, vehicle, electronic device and computer-readable storage medium for shifting control of a hybrid transmission. Background technique [0002] At present, the hybrid configuration at home and abroad is mainly divided into a hybrid powertrain based on a traditional gearbox and a new hybrid powertrain. The configuration of the hybrid powertrain based on the traditional gearbox is mainly transformed on the basis of the traditional gearbox. The structure and strategy of the gearbox have not changed much. Therefore, this type of configuration has the weight, layout and additional cost issues. The configuration of new hybrid transmissions, often in a monolithic, system-based design approach, greatly reduces redundant components, making hybrid powertrains more compact, efficient, and cost-effective....

AI Technical Summary

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.
