Control method for integrating electric stepping control function of automobile and automobile body controller

Abstract

The invention relates to a control method of an automobile integrated electric stepping control function and an automobile body controller. The automobile body controller comprises a power supply module, a CAN control module, a first switch acquisition module, a second switch acquisition module, an MCU controller, a stepping motor PWM driving module, an alarm prompting module and a door lamp control module, wherein the power supply module is electrically connected with the MCU controller, the stepping motor PWM driving module, the alarm prompting module and the door lamp control module respectively; the first switch acquisition module, the second switch acquisition module and the door lamp control module are respectively in electric signal connection with an input end of the MCU controller; and the alarm module and the stepping motor PWM driving module are respectively in electric signal connection with an output end of the MCU controller. According to the submersible vehicle, a vehicle speed signal is introduced in the step control to judge the vehicle driving state, when the door signal goes wrong, if the vehicle is in the driving state, the step can be retracted, and potential safety hazards in the prior art are made up.

Description

technical field [0001] The invention belongs to the technical field of automobile stepping control, and in particular relates to a control method and a body controller of an automobile integrated electric stepping control function. Background technique [0002] At present, in order to ensure the passability of the vehicle, most of the cars in the market have a high ground clearance of the door, which makes it difficult for drivers and passengers to get on and off the car, and there are certain safety hazards in some emergency situations. Especially in some subdivided vehicle types (such as commercial buses, school buses, etc.), there are higher requirements for the convenience and safety of drivers and passengers getting on and off the bus, which is the focus of people's attention. The existing main technical solution is to design a telescopic stepping device under the car door to reduce the ground clearance and facilitate the fast, comfortable and safe evacuation of the veh...

AI Technical Summary

Problems solved by technology

[0012] 1) Using an independent controller (the alarm system also uses an independent buzzer to alarm), the manufacturing cost is high

[0013] 2) The reliability of the controller is all based on the door state control, which requires high reliability of the door state. Once the door switch signal is unstable due to factors such as door adjustment errors or door matching problems after a period of use, It will bring serious consequences; especially when driving, if the door signal distortion is in the open state, it will cause the steps to protrude, scratch with the surrounding movement of the vehicle during driving, and cause major safety problems

[0014] 3) The controller does not have the capability of program online diagnosis and empty update. When a program fault occurs or the control algorithm is optimized, it needs to be removed and updated, or replaced, and the maintenance convenience is poor and the cost is high.

[0015] 4) The controller has a single function, poor expansion performance, and does not have the ability to iteratively upgrade
