Problems solved by technology

In this case, since the transmission performs shift control based on the torque value received by the CAN network, it will cause abnormal matching between the engine and the transmission, which will seriously affect the power, economy and failure rate of the vehicle.

Abstract

The present disclosure relates to an automatic transmission control method, device, vehicle and storage medium. The method includes: when the torque signal output by the engine control module in the vehicle fails, acquiring the accelerator pedal opening signal and the engine speed signal; based on the accelerator pedal opening The engine speed signal, the engine speed signal and the accelerator pedal curve are used to determine the actual output torque of the engine. Based on the actual output torque of the engine, shifting control is performed on the automatic transmission in the vehicle. The technical solution provided by the embodiments of the present disclosure can realize that the transmission can normally shift up and down when the torque signal fails, thereby ensuring that the engine and the transmission are always matched normally without affecting the power, economy and failure rate of the vehicle .

Description

technical field [0001] The present disclosure relates to the technical field of transmissions, in particular to an automatic transmission control method, device, vehicle and storage medium. Background technique [0002] Among the parts of automatic transmission fuel vehicles, the engine, transmission and chassis are called the three major parts of the powertrain. Among them, the relationship between the engine and the transmission is relatively close. In vehicle development, the matching of the two is an important research and development content. [0003] Research shows that in practice, there are situations where the actual output torque value of the engine is different from the torque value sent by the engine to other modules (such as transmission) through the CAN network. In this case, since the transmission performs shift control based on the torque value received by the CAN network, it will cause an abnormal matching between the engine and the transmission, which wil...
