Vehicle-status device and system for remotely updating and locally indicating the status of a vehicle

摘要

A vehicle status device and system for remotely updating and locally indicating the status of a vehicle. The vehicle status device is located in a vehicle and indicates status information for the vehicle on a vehicle-status indicator on the vehicle when the device is interrogated by an interrogating unit. The device includes a database of status information for the vehicle and owner. An update receiver in the device receives encoded updated information from a wide area paging network for storage in the database. An interrogation receiver receives an interrogation signal from the interrogating unit, and a processor decodes the status information and sends it to the status indicator in response. The system also includes an interrogating unit which includes a police radar transmitter or a laser transmitter for transmitting the interrogation signal to the vehicle status device. The status indicator includes a set of summary status lights and may also include an LCD display for detailed status information. In an alternative embodiment, the device uses a wireless Internet access device to access external databases and download the vehicle status information either periodically or on demand. The information may be passed directly to the status indicator without the need for an internal database.
