Low-Cost Embedded System Applied to Data Processing and Indicator Generation of Motor Vehicles

The performance of different automotive vehicles can be compared based on measurements of their real conditions parameters recorded over time, such as position, acceleration, battery consumption, engine speed, fuel type, transmission, odometry, and engine cooling temperature, among others. These parameters are essential for a true picture of the cars' situation, helping to reduce maintenance, e.g., fuel waste, toxic gas emissions, and predictive maintenance. It is important to note that in the literature, several pieces of equipment are inserted in the vehicle's network and exported information to the user online. However, products that access vehicle data and store it for an extended period are not easily available on the market. In most cases, the user only has access to products that show the vehicle's data while the device is connected. When the car is turned off, the data is lost. This work presents a product that fills these gaps, giving the owner a long-term history of the vehicle's information, showing it as easy to understand on a developed interface, and using accessible products to build the device. The tests indicated the product's effectiveness in getting long-term vehicle data for more than a month only using 1 % of its storage capacity. For last, research contemplating 1000 possible customers was also implemented to validate product price and interest on the market.
