System for indicating status of a vehicle
First Claim
1. A system for indicating status of a vehicle, comprising:
- a monitoring unit, positioned within the vehicle, comprising a first memory circuit connected with a first transceiver, said monitoring unit being arranged to monitor a selected set of parameters in the vehicle, whereby the current status of each parameter in said set of parameters is regularly detected and stored in said first memory circuit; and
a portable fob unit having a second transceiver;
said transceivers being arranged to establish a short-distance wireless communication link between said fob unit and monitoring unit when within a communication range from each other, said system further comprising a first register arranged to store a preferred or pre-set status of each parameter in said set of parameters, and a comparator, wherein the comparator is arranged to compare the contents of said first memory unit and the first register, and output an alert signal if the status of any parameter in the monitored set of parameters differs from its preferred or pre-set status as stored in said register, said alert signal being transmittable to an alert device in said fob unit.

Abstract
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).
