Problems solved by technology

However, the on-board diagnostic system does not perform batch storage, forwarding, statistics, and analysis of the original data stream collected by the engine ECU, nor can it provide suggestions for ECU improvement according to different environmental factors and different driving habits. According to the proportional distribution of the data to understand your own driving habits, you can’t get information such as whether your car needs power upgrades. For this reason, this invention proposes a personalized service system based on EFI engine ECU

Abstract

The invention provides a personalized service system based on an electric control unit of an electronic-injection type engine, and belongs to the technical field of automobile electronic and cloud computing. The structure of the system comprises an ECU data collection module (1), a wireless communication module (2), and a cloud computing processing module (3). The ECU data collection module (1) and the wireless communication module (2) achieve the collection of data in an ECU, and transmit the data to a cloud terminal. The cloud computing processing module (3) describes the driving habits of different drivers through the statistics of the differences of proportional distribution of data of an accelerator pedal and the rotating speed of an engine, thereby enabling a user to know the driving habit and the state of the engine and to judge whether the ECU needs to be upgraded or not. The system is high in accuracy of collected data, is high in authenticity, is more stable, can provide a simple, high-performance and low-cost network connection mode for a user, and can enable the user to know the condition of proportional distribution of data of the electric control unit truly.

Description

technical field [0001] The invention belongs to the technical fields of automotive electronics, wireless communication and cloud computing, and in particular relates to a personalized service system based on an electronic control unit of an electronic fuel injection engine of an automobile. Background technique [0002] The ECU-Electronic Control Unit (ECU-Electronic Control Unit) in the high-pressure common rail system of a diesel engine is the core of the engine system to realize electronically controlled fuel injection. Due to the differences in fuel quality, latitude, atmospheric pressure, temperature and humidity, emission regulations, and engine form of each country, the original ECU program is the best compromise that meets many conditions, so the set data range is relatively conservative, and there are some differences. Great room for upgrades. Software engineers will have reservations about program adjustments. Generally speaking, the factory performance of a car c...
