Torque control method based on arbitration voting

Abstract

The invention provides a torque control method based on arbitration voting, and mainly aims at solving the problem of an existing internal combustion engine electronic torque control technology that the expansibility and maintenance property are poor. According to the control method, all working conditions can be used as independent arithmetic units for calculating respective accelerated speed predicated values; cooperated distribution is carried out by adopting a voting cooperated controller to obtain an optimal accelerated speed predicated value; the value is calculated to obtain a control torque. The torque control method has the advantages of balanced arithmetic balance, easiness of expansion, easiness of maintenance and low cost, and can be used for torque control arithmetic processes in the fields of electronic power control of vehicles, ships, aviation and the like.

Description

technical field [0001] The invention belongs to the technical field of internal-combustion engine power control, and specifically relates to a torque-control-based internal-combustion engine power control method, which is used to calculate the driving torque under the background of complex working conditions to drive the engine to run normally. Background technique [0002] At present, the torque-based power control method is a mainstream method of internal combustion engine power control. The characteristic of this method is to connect the expected value of the upper power control with the power drive of the actual actuator by using the driving torque as a link. running state, and effectively improve the economy of fuel utilization. [0003] In the traditional torque-based power control method, the required torque generated by the upper-level control command (such as the accelerator pedal of the vehicle engine) is used as the main torque, and the torque of other working co...

Problems solved by technology

When the applicable working conditions of the internal combustion engine model change, the entire torque calculation model needs to be adjusted, which is not conducive to the upgrade and maintenance of the control software

[0004] On the other hand, torque components need to be calculated separately for each working condition. In the field of internal combustion engine control, torque control algorithms are usually more complicated, and automatic control algorithms such as PID need to be used for calculations, and this process is usually slow and complicated.

Therefore, the computational efficiency of this control method is not high, which is not conducive to the use of low-configuration controllers.
