Abstract

The present invention relates to a system for use in a vehicle for determining in real time whether to permanently store vehicle data indicative of at least one vehicle-related feature during a vehicle journey. The system includes receiving means configured to receive the vehicle data from at least one subsystem of the vehicle, and means configured to permanently store the vehicle data indicative of the at least one vehicle-related feature at a first location of the vehicle journey as a permanent data point. In addition, there includes means configured to temporarily store the vehicle data indicative of the at least one vehicle-related feature at a second location of the vehicle journey as a temporary data point, the second location being subsequent to the first location. Further, the system includes determination means operable during the vehicle journey to determine an equation of the straight line passing through the permanent data point and a current data point indicative of the at least one vehicle-related feature at substantially a current location of the vehicle, and to determine a shortest distance between the temporary data point and the determined straight line. The determination means is configured to permanently store the temporary data point as a permanent data point only if the calculated shortest distance is greater than a predetermined threshold distance value.
