Abstract
A system for evaluating a state of a tire on a vehicle is provided. The system includes a housing, first and second sensors, and control electronics. The housing is located on a ground surface. The first sensor is installed in the housing and measures a first characteristic of a tire passing over the housing. The second sensor is installed in the housing and measures a second characteristic of a tire passing over the housing. The first and the second sensors are positioned such that instants of passage of the vehicle rolling over the housing at positionings of the sensors are distinct from each other. The control electronics determines a direction of rolling of the vehicle over the housing based on each of the positionings of the sensors in the housing and on the instants of passage of the vehicle over the sensors.

16. A system for evaluating a state of a tire on a vehicle, the system comprising:
-
a first housing positioned on a ground surface; a first sensor installed in the first housing and arranged to measure a first characteristic of the tire passing over the first housing, and a second sensor installed in the first housing and arranged to measure a second characteristic of the tire passing over the housing, wherein the first and the second sensors are positioned such that instants of passage of the vehicle rolling over the first housing at positionings of the first and second sensors are distinct from each other; and a controller that determines a direction of rolling of the vehicle over the first housing based on the positionings of the first and second sensors in the first housing and on the instants of passage of the vehicle over the first and second sensors. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method for determining a direction of rolling of a vehicle over a tire-state evaluation system that includes a first housing positioned on a ground surface, a first sensor installed in the first housing and arranged to measure a first characteristic of the tire passing over the first housing, a second sensor installed in the first housing and arranged to measure a second characteristic of the tire passing over the housing, wherein the first and the second sensors are positioned such that instants of passage of the vehicle rolling over the first housing at positionings of the first and second sensors are distinct from each other, and a controller that determines a direction of rolling of the vehicle over the first housing based on the positionings of the first and second sensors in the first housing and on the instants of passage of the vehicle over the first and second sensors, the method comprising steps of:
-
detecting a crossing of a first voltage threshold by the first sensor; detecting a crossing of a second voltage threshold by the second sensor; and determining the direction of rolling of the vehicle based on the positionings of the first and second sensors and on a chronology of the crossing detected by the first sensor and the crossing detected by the second sensor.

28. A method for determining a direction of rolling of a vehicle over a tire-state evaluation system that includes a first housing positioned on a ground surface, a first sensor installed in the first housing and arranged to measure a first characteristic of the tire passing over the first housing, a second sensor installed in the first housing and arranged to measure a second characteristic of the tire passing over the housing, wherein the first and the second sensors are positioned such that instants of passage of the vehicle rolling over the first housing at positionings of the first and second sensors are distinct from each other, and a controller that determines a direction of rolling of the vehicle over the first housing based on the positionings of the first and second sensors in the first housing and on the instants of passage of the vehicle over the first and second sensors, the method comprising steps of:
-
detecting a crossing of a first voltage threshold by the first sensor; detecting a crossing of a second voltage threshold by the second sensor; and calculating a speed of the vehicle by dividing a distance between orthogonal projections of the positionings of the first and second sensors on a planar upper face of the first housing by an elapsed time between the crossing detected by the first sensor and the crossing detected by the second sensor. - View Dependent Claims (29, 30)
