Control method applied to automobile controller

Abstract

The invention provides a control method applied to an automobile controller. Embedded software and hardware of an electronic controller, a control, calibration and diagnosis system, a system working process, a CAN and subsystem data interaction method, a mode switching and processing method and a torque calculation method of a motor during power assisting, intelligent charging and energy recoveryare designed. An electronic turbine CAN increase the engine peak torque at a low rotating speed, the electronic turbine CAN increase the engine torque response speed, especially the sudden high-powerrequirement of high-fuel oil, the 48V electronic turbine CAN rapidly complete the voltage buildup process, and engine torque rising is faster than that of an exhaust turbine.

Description

technical field [0001] The invention belongs to the field of automobile controllers, and in particular relates to a control method applied to automobile controllers. Background technique [0002] With the increasingly stringent regulations on vehicle emissions and fuel consumption, and consumers' higher requirements for vehicle drivability and comfort, OEMs have conducted a lot of research on how to reduce fuel consumption and improve power performance. [0003] In recent years, major OEMs have launched 48V hybrid solutions in P0 configuration. These solutions can realize functions such as start-stop, energy recovery, and power assistance, which not only improve power performance, but also reduce vehicle fuel consumption. More importantly, the cost of the 48V solution is relatively low, the changes to the original fuel vehicle are small, and the cost performance is outstanding. [0004] The core of the 48V hybrid control system, that is, the control strategy has always been...

AI Technical Summary

Problems solved by technology

[0004] The core of the 48V hybrid control system, that is, the control strategy has always been controlled by foreign electronic control giants. There are no mature control, calibration, and diagnosis strategies in China that have been used in mass-produced models.

[0005] The current control system has the following two problems: 1) Insufficient exhaust gas energy at low engine speeds results in limited supercharging effect; 2) Insufficient pressure build-up speed at the intake end caused by turbo lag results in slow engine torque response
