[0113] Based on the above-mentioned first embodiment of the upshift control device of the present invention, a second embodiment of the upshift control device of the present invention is proposed.

[0114] In this embodiment, the working condition identification module 10 is also used to determine the current vehicle driving condition according to the vehicle speed signal and the accelerator pedal signal on the CAN bus; according to the current vehicle driving condition, current gear, The state of the brake pedal and the grade signal determine the target gear.

[0115] Further, the torque compensation module 20 is also used to control the vehicle to perform pre-shift according to the target gear; when the vehicle pre-shift is completed, control the vehicle to perform pre-filling; when the vehicle pre-filling is completed, control The vehicle performs torque swapping and torque compensation at the start of the torque swapping to increase wheel end torque.

[0116] Further, the...

Abstract

The invention relates to the technical field of automobiles and discloses an upshift control method, device and equipment and a storage medium. According to the method, the current whole vehicle driving working condition is obtained, the target gear is determined according to the current whole vehicle driving working condition, then upshift operation is executed according to the target gear, torque compensation is conducted when torque exchange starts so as to increase the torque of a wheel end, then torque compensation is stopped when torque exchange ends, and the rotating speed of the engine is adjusted; and then whether upshift of the vehicle succeeds or not is judged according to the adjusted engine rotating speed and the target gear rotating speed corresponding to the target gear. The method is advantaged in that torque compensation is carried out when torque exchange starts to increase the wheel end torque, torque compensation is stopped when torque exchange ends, the wheel end torque can be effectively compensated, and then whether upshift of the vehicle succeeds or not is judged according to the adjusted engine rotating speed and the target gear rotating speed corresponding to the target gear; therefore, gear shifting jerking caused by different gear speed ratio differences and energy loss in the upshift process can be effectively compensated.

Description

technical field [0001] The present invention relates to the technical field of automobiles, in particular to an upshift control method, device, equipment and storage medium. Background technique [0002] At present, the upshifting process of the dual clutch transmission is a process in which the dual clutch transmission control module (TCU) recognizes the driver's intention and controls the transmission actuator to change from a low gear to a high gear according to input signals such as vehicle speed and accelerator pedal. The traditional dual-clutch transmission has the following problems in the upshifting process: 1. During the upshifting process, the speed ratio becomes smaller and the torque transmitted to the wheel ends of the vehicle decreases, so the vehicle has obvious frustration during the upshifting process; 2. The shifting process of the dual-clutch transmission is refined, which cannot fundamentally solve the problem of vehicle shifting frustration caused by the...
