Abstract
A vehicle data storage system is provided which includes a plurality of sensors for sensing vehicle operating conditions, such as engine temperature. A control module receives the vehicle operating conditions and translates the vehicle operating conditions into vehicle information. A portable hand held computing device, such as a Handspring® or Palmpilot®, has a data storage device or memory that receives the vehicle information. The data storage device is limited by a particular memory capacity. A secondary storage device receives the vehicle information from the data storage device from the portable hand held computing device when the memory capacity reaches a desired memory capacity level, such as when there is only 10% of the memory left in the data storage device. Additionally, one of the vehicle operating conditions in one of the subsystem control modules may comprise a triggering event. The triggering event may be detecting a high engine temperature in an engine temperature sensor. The subsystem control module then produces a request signal for event data in response to the triggering event. A memory buffer stores the vehicle information from all of the subsystem con…
