Estimating the term…
A speed evaluation system is provided for assessing a speed of a vehicle. The speed evaluation system includes a wear measurement system, which assesses a state of a tire of the vehicle. The wear measurement system includes a casing placed on a ground surface. The speed evaluation system further includes a timing device that determines at least two instants of passage of the vehicle over two distinct or non-distinct points of passage of the casing of the wear measurement system, and a processor that calculates, as a function of the instants of passage and of dimensional data of the casing and/or dimensional data of the vehicle, a speed of passage of the vehicle over the casing. A method of implementing the speed evaluation system also is provided.
1-12. (canceled)
13:
The speed assessment system according to claim 13, wherein the tire measurement system is a wear measurement system.
The speed assessment system according to claim 13, further comprising a memory, which stores the dimensional data of the casing.
The speed assessment system according to claim 13, further comprising a reader, which reads vehicle identification information.
The speed assessment system according to claim 13, further a communication device, which exchanges information with a remote database, the exchanged information including the dimensional data of the vehicle.
19:
The method according to claim 19, wherein the steps of determining the first instant of passage and determining the second instant of passage include detecting a passage of a same wheel at two different points of the casing.
The method according to claim 19, wherein the steps of determining the first instant of passage and determining the second instant of passage include detecting a passage of two distinct axles of the vehicle at a single point of the casing.
The method according to claim 19, wherein the steps of determining the first instant of passage and determining the second instant of passage include detecting a passage of two distinct axles of the vehicle at two distinct points of the casing.
The method according to claim 19, wherein the steps of determining the first instant of passage and determining the second instant of passage include detecting an impact on the casing and detecting a passage of a wheel at a point of the casing.
The method according to claim 19, further comprising a step of correcting a determination of the first instant of passage based on a rigidity of a material forming the casing.
