Bus co-processor information transmitting system in combination with mobile phone and automobile body bus

Abstract

The invention discloses a bus co-processor information transmitting system in combination with a mobile phone and an automobile body bus. The system herein includes: an automobile body bus, a co-processor module and a smart phone module. The automobile body bus is disposed inside the automobile body and is intended for extracting vehicle condition information and conducting analog-digital conversion. The co-processor conducts communication with the automobile body bus and the smart phone module and is intended for processing signals on the body bus and the smart phone and realizing mutual connection between two devices. The smart phone module is intended for visualizing a to-be-transmitted command and the data returned by the co-processor, and at the same time using platform computing resources provided therein to increase the computing capability of an onboard processing terminal in the automobile body bus. According to the invention, the system herein can use the smart phone to real-time transmit commands to an automobile and receive vehicle feedback and vehicle condition information, also effectively uses the platform computing resources of the smart phone, and addresses the insufficient computing capability of onboard processing terminals that are currently in the market.

Description

technical field [0001] The invention relates to CAN bus technology and the field of communication between vehicles and smart phones, in particular to a bus coprocessor information transmission system combining the bus of the mobile phone and the car body. Background technique [0002] In the 21st century with the rapid development of economy and technology, automobiles, as an efficient and convenient means of transportation, have become an indispensable part of modern people's lives. However, no matter how sophisticated the automobile is, it will always produce Some problems that affect the normal driving of the driver, such as the temperature of the fuel tank of the car, the idle speed, the position of the idle throttle valve and other parameters may affect the normal driving of the car, that is, affect the health of the car. Poor vehicle health will not only affect the driving condition of the vehicle, shorten the life of the vehicle, and reduce the driver's experience. In...

[0002] In the 21st century with the rapid development of economy and technology, automobiles, as an efficient and convenient means of transportation, have become an indispensable part of modern people's lives. However, no matter how sophisticated the automobile is, it will always produce Some problems that affect the normal driving of the driver, such as the temperature of the fuel tank of the car, the idle speed, the position of the idle throttle valve and other parameters may affect the normal driving of the car, that is, affect the health of the car

Poor vehicle health will not only affect the driving condition of the vehicle, shorten the life of the vehicle, and reduce the driver's experience. In severe cases, it may directly lead to the scrapping of the vehicle and even cause traffic accidents

Although different faults will correspond to different fault codes, and various parameters can also be obtained on the car body bus, it is difficult for people who use cars every day to read information directly from the body bus

On the other hand, as people have put forward higher requirements for the automobile industry, the requirements for personalized customization of users have become more and more prominent, and the processing capacity of vehicle information has continued to increase. The existing vehicle information processing terminals often face insufficient computing resources. dilemma

The smart phone computing platform has abundant computing resources, strong data analysis and result presentation capabilities, but lacks an effective way to combine with the automotive bus
