Accurate Speed Measurement Methodologies for Formula One Cars

Abstract

There are several methods of speed measurement for F] applications. In this paper, two measurement systems realized for this aim, a GPS-based and a contact-less sensor based one, are presented. The theoretical disadvantages and practical risks for each solution are described. Particular attention is focused on the solution based on contact-less optical speed sensor, currently considered the best way to satisfy the requirements ofthe very harsh racing environment. The first results of laboratory experiments carried out using such sensor, show possible short-term improvements.

A New Technique on Vibration Optimization of Industrial Inclinometer for MEMS Accelerometer Without Sensor Fusion

“…To measure roll and pitch, various formulas have been applied [31], [32]. In this work, 2 fundamental formulas are used for oriental inclination.…”

The role of GNSS in the navigation strategies of cost-effective agricultural robots

“…Likewise, the cross-track 61 DOP (XDOP) perpendicular to the travel direction increases as the reference axis changes 62 from 0º to 90º, which explains the direction dependency of cross-track errors. GPS-based 63 velocity estimation, on the other hand, usually provides positive results as long as there 64 are no satellite coverage discontinuities provoked by overhead structures, electromagnetic 65 interferences onboard are kept low, and multipath signal reception is reduced as much as 66 possible, especially reflections caused by water bodies (Cocco and Rapuano, 2007). 67…”

Electronic differential design for a vehicle with four independently controlled in-wheel motors

“…In some parts of this paper it is assumed that the yaw rate and the ground vehicle speed are available through continuous sensing. Ground speed sensors using optical means are found in [11], [12]. Other speed estimation methods have also been proposed in the literature including in [13].…”
