Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0017] The purpose of the present invention is to provide a vehicle body controller based on the remote diagnosis system of the CAN bus, which sends corresponding control commands through the application program of the smart phone platform, and after the controller GPRS module receives the information of the mobile phone, it encapsulates or parses the corresponding data format , through the CAN bus communication and diagnosis system, the body load module is driven, so that the control and diagnosis of the body load can be realized.

[0018] see figure 1 , the present invention is a vehicle body control system based on a CAN bus remote diagnosis system. The remote diagnosis vehicle body control system includes a vehicle body controller and a smart phone. The body controller includes a GPRS communication core module SIM300 module, an MCU, a load driv...

Abstract

The invention relates to a vehicle body control system, in particular to a vehicle body control system and method based on a remote diagnosis system of a CAN bus, and belongs to the technical field of vehicle body controllers. The vehicle body control system based on the remote diagnosis system of the CAN bus is characterized by comprising a vehicle body controller and a mobile phone. The vehicle body controller comprises a GPRS communication module, an MCU, a load drive module and a CAN bus communication and diagnosis module. The GPRS communication module is connected with the CAN bus communication and diagnosis module and then connected to the MCU. The load drive module is connected with the MCU. The GPRS communication module and the mobile phone are in wireless communication. An application program of the mobile phone inquires, monitors and diagnoses the whole vehicle body controller through a corresponding interface. The MCU is responsible for driving the corresponding vehicle body load through the drive module. The CAN bus communication and diagnosis module finishes the diagnosis of a short circuit and an open circuit of the load through a data protocol.

Description

technical field [0001] The invention relates to a vehicle body control system, specifically, a vehicle body control system and a control method of a CAN bus-based remote diagnosis system, and belongs to the technical field of vehicle body controllers. Background technique [0002] The body controller is also called a body control module (BCM for short). There are three methods of BCM control technology: decentralized, centralized and bus-based. At present, the BCM of high-end and high-end imported cars is developed and designed by foreign countries, such as Passat, Touran, Accord, Audi, Mondeo, Crown, Regal, etc. Domestic cars are also It has begun to develop from distributed BCM to bus BCM. CAN bus is a serial multi-master controller local area network bus. It is an inevitable trend in the development of BCM to use CAN bus technology to control vehicle body electronic and electrical devices, and the intelligence of CAN bus is getting higher and higher. The potential of th...
