Abstract

A vehicle information storage system for all vehicle electronic sensors comprising a condition monitoring subsystem(7) and a storage subsystem(9). The condition monitoring subsystem(7) comprises, display(30), warning lamps(32), and a central processing unit(24) with a microprocessor and memory. The storage subsystem(9) comprising a central data processor(31) with a plurality of storage devices(16) one for each of a plurality sensor inputs(11), a plurality of remote receiving units(10), and a data routing unit(14). All the sensor inputs in the storage subsystem(7) are connected to the central data processor(31) over a single wire with the centrally located data routing unit(14) and the plurality of remote receiving units(10). Each sensor input(11) is monitored according to the information content of the associated sensor data as determined by prior analysis. Each sensor data associated with each sensor input(11) is stored in a corresponding storage device(16) and is transmitted via the vehicle electronic interface(26) to the central processing unit(24) in the condition monitoring subsystem(7 ) or to an external computer. The central processing unit(24) in the condition monitoring subsystem(7) processes and stores some of the data associated with the sensor inputs(11). All the remaining sensor data associated with all the remaining vehicle electronic sensors is stored exclusively in the central data processor(31).
