A system for indicating status of vehicle

摘要

This invention relates to a system for indicating status of a vehicle, comprising a monitoring unit (1), positioned within the vehicle, comprising a first memory circuit (4) connected with a first transceiver (3). The monitoring unit (1) is arranged to monitor a selected set of parameters (22) in the vehicle (2), whereby the current status (22a) of each parameter in said set of parameters (22) is detected and stored in said first memory circuit (4). The system further comprises a portable fob unit (7) having a second transceiver (9). The transceivers (3,9) are arranged to establish a short-distance wireless communication link (8) between said fob unit (7) and monitoring unit (1) when within a communication range from each other. The system further comprises a register (23) arranged to store a preferred or pre-set status (22b) of each parameter in said set of parameters (22), and a comparator (25). The comparator (25) is arranged to compare the contents of said first memory unit (4) and the register (23), and output an alert signal (F) if the status of any parameter in the monitored set of parameters (22) differs from its preferred or pre-set status (24) as stored in said register (23). The alert signal (F) is finally transmittable to an alert device (28) in said fob unit (7).
