20120283944 | Method and system for mapping road conditions by means of terminals - The present invention relates to methods, computer software products, server and system for mapping road conditions, especially friction. In the method according to the invention the acceleration of the vehicle is measured b means of an acceleration sensor, the position of the vehicle is monitored by means of positioning means and the measured acceleration value is combined with the position data of the measurement location. The method compares whether the measured position-specific acceleration value exceeds the value on the server for the said area and in case the value is exceeded, a measured position-specific acceleration value is sent to the server. | 11-08-2012 |
