Abstract: Disclosed is a method for determining the installation orientation of an accelerometer system relative to a vehicle within which it has been installed. The method comprises obtaining a plurality of acceleration measurements within the co-ordinate frame of the accelerometer system and then analysing the distribution of these measurements to determine the relative installation orientation. In particular, the measurements can be grouped according to the vehicle movement phase at which they were obtained and the measurements within the groups then used to determine the lateral and horizontal planes of the vehicle.

Abstract: A server (16) arranged to automatically detect replacement of a vehicle battery (6) associated with a vehicle engine (5) comprises: a communications device (20) configured to receive vehicle battery voltage measurements from a telematics device (10) connected to or incorporating a voltage monitoring unit for the vehicle battery (6); and one or more processors (18) configured to process the vehicle battery voltage measurements. The processor(s) (18) monitor the voltage measurements in a first time window corresponding to an engine off state and assess when the voltage measurements in the first time window indicate a step change in voltage magnitude at a given time. The step change is then used to automatically identify a vehicle battery replacement event.

Abstract: There is disclosed a method of analysing tire temperature data from a temperature sensor arranged to measure the temperature of a tire on a vehicle. The method comprises receiving tire temperature data from the temperature sensor; receiving further data indicative of at least one different parameter related to the vehicle. The method further comprises determining expected temperature data based at least on the further data; and comparing the tire temperature data to the expected temperature data.

Abstract: An asset tracking system comprises a server (6), one or more first telematics devices (8) each carried by an asset, and one or more second telematics devices (10) each carried by a vehicle capable of transporting an asset. The server (6) comprises a communications device arranged to communicate with the one or more first telematics devices (8) and with the one or more second telematics devices (10). Each first telematics device (8) is configured to transmit asset travel data (12) to the server (6), and each second telematics device (10) is configured to transmit vehicle travel data (14) to the server (6). Each of the asset travel data (12) and vehicle travel data (14) comprise a plurality of data travel points each comprising a time stamp, position and a further motion-related parameter. The one or more first and second telematics devices (8,10) are each configured to communicate independently with the communications device of the server (6).
