Tire force estimation system using sensor data
The granted patent US12039812B2 outlines a tire force estimation system designed to enhance vehicle performance by accurately measuring and calculating the forces acting on each tire. The system comprises multiple components, including an acceleration sensor positioned on various parts of the tire (tread, side, and bead) to measure acceleration. This data is processed by a sensor information acquisition unit, which feeds the information into a tire force calculator. The calculator employs an arithmetic model to determine key tire forces, including longitudinal, lateral, and vertical forces. Additionally, the system can incorporate correction and update processors to refine the model based on tire conditions and external information, ensuring accurate force estimations.
The patent also describes a comprehensive tire force estimation method that includes measuring acceleration, acquiring sensor data, and calculating tire forces using the arithmetic model. The system can be further enhanced with additional sensors, such as strain, pressure, and temperature sensors, to provide a more holistic view of tire performance. These sensors can be strategically placed on the tire and its components to gather relevant data. The model can be adjusted to account for various factors affecting tire performance, such as wear and road surface conditions. Overall, this innovative system aims to improve vehicle safety and efficiency by providing real-time insights into tire dynamics.
