Abstract
A system and method for determining the magnitude of a force acting on a tire are disclosed. Further, a sensor and a tire suitable for use in the system and method are also disclosed. The system comprises: a tire strain sensor mounted on the tire, for detecting a tire strain at the mounted position, and generating data representing tire strain; a sensor locator for locating the sensor on the tire; a memory in which data on the relationship between the tire strain and force acting on the tire at each of measuring points are stored; and a processor computing the magnitude of the force, using the data representing tire strain obtained from the tire strain sensor and the data on the relationship acquired from the memory based on the data on the sensor location obtained from the sensor locator. The method comprises: obtaining data on tire strain from a tire strain sensor mounted on the tire; locating the tire strain sensor, to obtain data on the position of the tire strain sensor; obtaining data on a relationship between the tire strain and the force at the located position of the tire strain sensor, from previously stored data on relationships between the tire strain and force at a plurality of sensor positions; and computing the force using the obtained data on the tire strain and the obtained data on the relationship between the tire strain and the force.
