Problems solved by technology

[0003] However, now many buses and group buses, in order to meet the maximum speed limit required by the national standard, after the vehicle speed reaches the target speed, the vehicle controller sends a zero torque command. When the vehicle speed is lower than the limited threshold, the normal driving mode is restored, resulting in The actual vehicle shakes abnormally and is out of control, which must be a safety hazard

Embodiment Construction

[0051] In order to facilitate a better understanding of the present invention, the present invention will be further explained below in conjunction with the accompanying drawings of related embodiments. The embodiments of the present invention are shown in the drawings, but the present invention is not limited to the above-mentioned preferred embodiments. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more fully.

[0052] The vehicle controller of the electric bus is the core control component of the vehicle. It collects the accelerator pedal signal, brake pedal signal, gear signal, motor signal and other component signals, and after making corresponding judgments, it controls the lower component controllers Actions. The core idea of ​​the present invention is to control the driving torque of the motor after corresponding judgments on the collected signals, thereby realizing the limitation of the speed of the electr...

Abstract

The invention provides an electric bus torque regulation control method and system, a mobile terminal and a storage medium. The electric bus torque regulation control method comprises the steps of obtaining a motor rotation speed parameter of an automobile and performing jitter eliminating processing on the motor rotation speed parameter so as to obtain a rotation speed optimization parameter; obtaining a driving parameter of the automobile and carrying out torque demand calculation on the driving parameter and the rotation speed optimization parameter so as to obtain a motor torque demand value; calculating an automobile speed difference between a current automobile speed and a target automobile speed of the automobile; judging whether the automobile speed difference falls within a firstpreset automobile speed range or not; if the automobile speed difference falls within the first preset automobile speed range, correcting the motor torque demand value so as to obtain a motor torque corrected value, and transmitting a torque regulation instruction to the automobile according to the motor torque corrected value so as to obtain the automobile to regulate the torque; and if the automobile speed difference does not fall within the first preset automobile speed range, directly transmitting the torque regulation instruction to the automobile according to the motor torque demand value so as to control the automobile to regulate the torque. According to the electric bus torque regulation control method and system, the mobile terminal and the storage medium, the stability accuracyof the control process is high, and a phenomenon that abnormal jitter near the target automobile speed is out of control is eliminated.

Description

Technical field [0001] The invention relates to the technical field of new energy buses, and in particular to a torque adjustment control method, system, mobile terminal and storage medium for electric buses. Background technique [0002] New energy vehicles are developing rapidly in China, especially in the passenger car industry. Most cities in China are gradually replacing traditional internal combustion engine buses and adopting pure electric-driven buses. Electric vehicles use electric energy as power, are driven by motors, have the advantages of fast speed increase, stable driving, easy maneuvering, no pollution and energy saving. The market is more and more willing to accept new energy vehicles, and they are rapidly gaining popularity. [0003] However, many buses and group buses nowadays, in order to meet the maximum speed limit required by the national standard, the vehicle controller sends a zero torque command after the vehicle speed reaches the target speed. When the ve...
