A SYSTEM FOR DETECTION OF DISORIENTATION AND MISALIGNMENT OF GNSS ANTENNAS IN A VEHICLE
TECHNICAL FIELD
[0001] The present disclosure relates to a diagnostic system for detection of state of component of a vehicle and transmit data revealing the issues with regard to the particular component for corrective actions. In particular, the present disclosure relates to the system facilitating detection of disorientation and misalignment of GNSS antennas in a vehicle in order to prevent degradation of in signal reception from a Global Navigation Satellite System (GNSS).
BACKGROUND
[0002] In recent times, automotive industries are coming up with technologies in order to provide a hassle free experience to the driver and the co-passengers. Telematics is a communication system for automotive industries that relies on data travelling to and from the automobile by virtue of wireless networks. Telematics control units (TCUs) are commonly placed in both horizontal and vertical orientations, in various locations of vehicle depending on presence of an in-built antenna or an external antenna such as to ensure minimum obstructions in signal reception by the antenna. The telematics control unit (TCU) is primarily responsible for collection of different telemetry data, for example, position, speed, engine data, connectivity information from the vehicle etc. Additionally, a telematics control unit (TCU) also comprises of a global navigation satellite system (GNSS) signal receiver for keeping track of location telemetry data values of the vehicle through one or more GNSS antennas.
[0003] In an existing arrangement, an automotive dealer can fit the telematics control unit (TCU) with an in-built GNSS antenna or with external GNSS antenna, where the GNSS antennas are configured to receive global positioning system (GPS) or any other Global Navigation Satellite System (GNSS) based signals and transmit the location telemetry data to a communicating device of a user through the telematics control unit (TCU), accordingly.
[0004] In some scenarios, misalignment or loose fitment or long term vibrational impacts on the vehicle, the telematics control unit (TCU) along with the in-built GNSS antenna or the screws holding the external GNSS antennas may become loose thereby resulting into tilting/disorientation of the antennas. Consequently, GNSS Antenna Module combined with metal parts in very close proximity (i.e., surround metal parts may get introduced between antenna and satellite view due to misorientation) may lead to degradation in GNSS antenna signal reception. Loose fitment or misalignment of the GNSS antennas may also result into incorrect alerts related to reading of the accelerometer for driving behavior events or tow away events which in turn may completely mislead the dealer and/or end user.
[0005] The disorientation and misalignment or loose fitment of the GNSS antennas may also result into sending invalid GNSS location owing to poor quality of GNSS signal, which in turn will lead to incorrect display of information by the telematics detection unit (TCU) and cause dissatisfaction to the customers. Further, in an event of safety hazards, the telematics control unit (TCU) will also not be able to share precise actual location of the vehicle to emergency services like Ambulance in case of events like vehicle intrusion and emergency call (crash event or safety critical condition)
[0006] However, in the existing arrangement, there are no such provisions of detection of disorientation and misalignment of the telematics control unit (TCU) or the external GNSS antennas of a telematics system in the vehicle without having an inspection by a trained dealer after reports of incorrect locations or misleading alerts and therefore, this may lead to delayed or no response in event of an emergency event like accident or medical emergency if the user was unaware of presence of misalignment/loose fitment of antenna.
[0007] Towards this direction, there is a pressing need for design and development of a system that can proactively detect disorientation and misalignment of the telematics control unit (TCU) or the external antennas in the Telematics System of the vehicle and alert the user accordingly to get this condition corrected proactively.
