Title:
METHOD AND DEVICE FOR MEASURING TIRE GROUND CONTACT PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2018/092334
Kind Code:
A1
Abstract:
In the present invention, virtual regions each having a width of 1/2n (where n is a natural number greater than or equal to 1) of the detection width W1 of a force sensor 3 provided on a tire travel surface 1 are set in a region to be measured of a tire T. The contact position between the tire travel surface 1 and tire T is shifted along a prescribed direction such that the force sensor 3 touches a single virtual region a plurality of times, and the sensor 3 is used to carry out force measurement a plurality of times. Mapping data is generated that associates each measurement time with data about the positional relationship between the virtual regions and sensor 3. Force values for each virtual region are calculated on the basis of the sensor 3 detection values and the force balance relationship between the sensor 3 and virtual regions determined by a mapping data generation unit 43.
