Vehicle key for starting engine of e.g. station wagon, has integrated storage device for storing internal dimensions of motor vehicle, and integrated longitudinal measuring device for detecting dimensions of object

摘要

The key (1) has an integrated storage device i.e. chip (4), for storing internal dimensions of a motor vehicle. An integrated longitudinal measuring device (5) detects dimensions of an object i.e. piece of furniture, where the longitudinal measuring device is a laser distance meter, ultrasonic sensor, radar distance meter or three dimensional-scanner. An optical and/or acoustic indicator (6) e.g. red and/or green LED and/or loudspeaker, displays a request for dimension of different sizes. Input measurements into an interior of the motor vehicle are provided.
