A multi-user vehicle telemetric system comprises vehicle interface units (VIUs), wireless gateways, and one or more central hosts. The VIU in a vehicle collects data over the OBD-II bus and stores the data in the form of DataPoint Records (DPRs) in an on-board non-volatile (e.g. flash) memory. When the VIU is within wireless range of a gateway, it establishes a WiFi (802.11b) connection with the gateway, and submits stored DPRs to the gateway, to be stored in permanent storage at the gateway. Although the DPRs are stored in permanent storage on the gateway, they are deleted from permanent storage on the gateway after they are successfully uploaded to the central hosts. The gateways are shared, and communicate with the central hosts over a wide area network (WAN). When a gateway has gathered new DPRs from a VIU, it submits these to selected central hosts. The central hosts collect vehicle data for a plurality of users, each user being assigned a central host exclusively, or sharing a central host with other users. Each of the VIUs may be exclusively accessed by a single user or a number of users, and the shared gateways forward DPRs from a VIU only to the central hosts of the users which are authorized to access the VIU.

A system as described in claim 10, wherein the means for determining comprises a database stored in a computer memory along with a software for data processing. 13. A system as described in claim 1, wherein the means in the VIU comprises a data collection table stored in a memory and a control program therefor. 14. A system as described in claim 13, wherein the data collection table comprises an entry for each type of data to be collected, and a collection specification regarding the time interval and the condition for performing the data collection and storage for each type of data to be collected. 15. A system as described in claim 14, wherein the entry for each type of data to be collected comprises a value identifier linking the type of data to be collected and the collection specification to the data collection profile. 16. A system as described in claim 15, wherein the entry for each type of data comprises designations specified by SAE (Society of Automotive Engineers). 17. A system as described in claim 1, wherein the access to sensors is provided by an OBD-II bus. 18. A vehicle interface unit (VIU) for a multi-user motor vehicle telemetric system, comprising one or more central hosts connected to a communications network, each central host being associated with one or more users of the system, one or more gateways connected to the communications network, the communications network enabling the transfer of data between the gateways and the central hosts, the VIU being placed within a vehicle and having access to sensors in the vehicle for collecting vehicle related data, the VIU further having means for communication over a wireless link to gateways to be accessed by the VIU when the VIU of the vehicle is within a transmission range of one of said gateways, and wherein each VIU is associated with one or more of the users, each central host having means allowing each user to specify the data to be collected from its associated VIUs through individual data collection profiles which are stored in the central host and the gateways and forming a combined data collection profile forwarded to the VIU, the VIU comprising: (a) means for storing the combined data collection profile; and (b) means for collecting the data required to be collected from the vehicle according to the combined data collection profile for all users associated with said VIU. 19.
