Abstract

This article describes how to enhance security on vehicles with a combination of existing hardware and changes to current software. It proposes the use of omnidirectional antennas on the vehicle’s Bluetooth device, enabling the car to detect the angle of arrival of the wireless signal, it’s worth to mention here that the angle of arrival cannot be detected with any type of antenna. Along with this new hardware blend, changes in the software of the car and the user device are proposed to allow the user device to take appropriate action when a SMS text arrives, based on this information the user device will be able to determine if the user is located in the drivers position.

Method and apparatus to enhance safety on vehicles by adjusting functionalities on mobile devices

SMS texting is a very dangerous source that can cause accidents during driving. A lot of solutions are available to increase safety, but none of them try to restrict the SMS user when driving the vehicle. Current solutions include, voice recognition, applications that stops receiving messages and responds to automated messages. The NHTSA (National Highway Traffic Safety Administration) and the Department of Transportation want automakers to make it impossible to enter text for messaging and internet browsing while the car is in motion, disable any kind of video functionality and prevent text-based information such as social media content or text messages from being displayed on smartphones ( http://www.nhtsa.gov/About+NHTSA/Press+Releases/U.S.+DOT+Releases+Guidelines+to+Minimize+In-Vehicle+Distract ions).

This invention goes beyond that, using Bluetooth* technology and an omnidirectional antenna on the vehicle. The smartphone or user device will be able to determine if the user is on the driver's seat with the help of an algorithm to detect the angle of arrival, after the position of the user is determined, the smartphone will be able to trigger an action based on predefined options, some of these options could include: reply a message, hold the messages, read out loud the message, etc.

Mobile devices that have Bluetooth devices are commonly connected to vehicles in order to allow users to perform hands free calls and listen to music, this disclosed model starts when the device pairs with the vehicle. During the pairing process, the vehicle device could measure the RSSI signal strength, angle of arrival of the signal and other parameters relative to the connection. This proposed invention uses this capability and involve changes to the Bluetooth API to allow a smartphone to query the angle of arrival and the RSSI signal strength periodically.

The detection system, is composed of 2 parts, t...
