A Low-Cost Data Acquisition System for Automobile Dynamics Applications

Abstract

This project addresses the need for the implementation of low-cost acquisition technology in the field of vehicle engineering: the design, development, manufacture, and verification of a low-cost Arduino-based data acquisition platform to be used in <80 Hz data acquisition in vehicle dynamics, using low-cost accelerometers. In addition to this, a comparative study is carried out of professional vibration acquisition technologies and low-cost systems, obtaining optimum results for low- and medium-frequency operations with an error of 2.19% on road tests. It is therefore concluded that these technologies are applicable to the automobile industry, thereby allowing the project costs to be reduced and thus facilitating access to this kind of research that requires limited resources.

The Acquisition Rate and Soundness of a Low-Cost Data Acquisition System (LC-DAQ) for High Frequency Applications

“…Given this situation, we recently introduced an alternative low-cost acquisition system based on the Arduino platform [1]. In that study, we validated the low-cost system presented with a professional data acquisition system for vehicular dynamics applications.…”

“…However, the specific applications in which Arduino-or Raspberry Pi-based systems have been used for vehicular dynamics applications are still limited. In the system presented in a previous article [1], we already have shown that it was possible to dynamically use a system based on an Arduino microcontroller to perform dynamic measurements in vehicles. However, little attention has been given in the relevant literature to improving the sampling frequency and the reliability of these low-cost systems.…”

“…Taking the system used in dynamic applications described in [1] as a reference, it would be desirable to increase the already high acquisition rate provided. In addition, communication through the serial ports between the system of Arduino (that provides the measure of the real time) and the central computer (that can be based on a Raspberry Pi in case of wanting to maintain the cost low) can have transmission errors that one has to monitor.…”

“…Therefore, the scientific novelty of this paper is centered on the development of a novel DAQ, based on affordable electronics for real-time applications in vehicular dynamics that, apart from allowing the open installation of a wide variety of sensors, multiplies by two the acquisition rate of the system presented in [1] and assures consistent reliability of the acquired data, checking and automatically correcting the detected errors. Specifically, this new system includes the configuration of new hardware, with a redesigned shield adapted to be modular and open to innumerable types of analog and digital sensors (position sensors, accelerometers, GPS, etc.).…”

Obstacle Avoidance System for Unmanned Ground Vehicles by Using Ultrasonic Sensors

“…In Gonzales et al (2018), the use of low-cost devices for obstacle avoidance in automotive engineering was reported. The authors in particular used an Arduino Microcontroller to acquire data to be used in vehicle dynamic analysis, demonstrating that such a low-cost technology is applicable to the automotive industry, reducing project costs [16][17][18]. Negrete et al (2018) reported how the automation of small-and large-scale agriculture is of colossal importance, because applying mechatronic technologies to agriculture would help to stimulate productivity in the Mexican agricultural industry [19].…”
