Problems solved by technology

[0004] The defect of this system is that: with the increasing popularity of cars, non-professional car consumers and users are becoming the mainstream of car consumption, and non-professional users are generally not very familiar with the structure, performance, status, etc. of cars. familiar
When encountering some problems, especially when the car breaks down, it is often impossible to make an accurate judgment on these problems or the phenomenon of the fault, which makes it difficult for car manufacturers and service providers to provide corresponding services for car consumers.
In addition, using a simple mobile phone with a service menu to communicate with the service center manually often cannot meet the requirements for the speed and quantity of information transmission in actual use

Embodiment 1

[0030] Embodiment 1: the control and processing device 70 is composed of two hardware modules, such as Figure 4 As shown, it includes a CPU 71 for processing application software, and a dedicated vehicle failure and running state analysis and detection module 72 . Wherein the input end of automobile failure and running state analysis detection module 72 is connected with the output end of each function ECU detection terminal 80 of the automobile, and the output end is connected with the input end of CPU 71; The raw data detected by each function ECU terminal 80 is analyzed to obtain the specific fault information of the car, and it can also be used to analyze the running status of the car, such as the mileage, speed, oil quantity, water temperature, engine speed, engine temperature and other states of the car. for analysis and monitoring. The CPU 71 includes embedded application software, which receives information from the vehicle failure analysis and running state analysis...

Embodiment 2

[0038] Embodiment 2: The control and processing device 70 is a computer system built in the automobile that includes special application software and a CPU. The application software includes an automobile fault analysis and detection system and an operating state analysis and detection system. In this example, the vehicle failure and running state analysis and detection module 72 implemented by hardware in the first embodiment is actually implemented in the CPU by software. Through the combination of software and CPU hardware, the functions of fault analysis and running status analysis mentioned above are realized. The computer system is connected with various functional ECUs of the automobile, the detection terminal 80 and the vehicle wireless communication terminal 60 through conventional connection methods and interfaces. The computer system can include a display screen and an input device.

[0039] The working process of the system is as follows:

[0040] When the car is...

Abstract

A vehicle-mounted information service terminal and vehicular special information service system includes a vehicle-mounted wireless communication terminal which communicates with the service center by the wireless communication network of existing mobile communication operator and acquires the information service provided by the service center. The system further includes a control and process device having an input terminal connected to the vehicle function ECU and detection terminals and an output terminal connected to the vehicle-mounted wireless communication terminal. The control and process device receives the data from the vehicle function ECU and detection terminals and processes the data based on program and generates related information. The invention makes the service center of vendor can quickly make accurate judgment for the vehicle true status, and provide effective service in time for user.

Description

【Technical field】 [0001] The present invention relates to a vehicle-mounted information service terminal and a vehicle-specific information service system, in particular to a vehicle-mounted wireless communication terminal, which is connected to a service center through the existing mobile communication operator's communication network. Service terminal and vehicle-specific information service system. 【Background technique】 [0002] With the continuous development of social economy, automobiles have entered people's daily life more and more as a new type of transportation. At the same time, people have higher and higher requirements for the performance of cars. With the development of modern communication technology, car users use modern wireless communication tools to connect with the service centers of car manufacturers, so that car manufacturers can provide car users with The automobile-specific information service system of information service also emerges at the histor...
