Ford exploring use of smartphone technology to alert drivers to pedestrians, bicyclists; BLE and 5G – Green Car Congress

Ford Motor Company is researching new smartphone-based communications technology that could potentially help warn drivers of pedestrians, bicyclists and moreeven those approaching a vehicles path but blocked from a drivers view.

The concept smartphone app, which would run on a pedestrians phone, uses Bluetooth Low Energy (BLE) messaging to communicate the phones location to a connected Ford vehicle. If the vehicle calculates a potential crash risk, Ford SYNC can alert drivers by the in-vehicle screen showing graphics of pedestrians, bicyclists or more with audio alerts sounding.

Ford, Commsignia, PSS, Ohio State University, T-Mobile and Tome Software are demonstrating the technology at the Intelligent Transportation Society of Americas World Congress in Los Angeles this week.

Newer Ford vehicles already with Ford Co-Pilot360 Technology can detect and help warn drivers of pedestrians, bicyclists, scooter riders and others and even apply brakes if drivers do not respond in time. We are now exploring ways to expand vehicle sensing capability, for areas drivers cannot see, to help people drive even more confidently on roads increasingly shared by others using their two feet or two wheels.

Ford is a founding member of the Vulnerable Road User Safety Consortium (VRUSC), a consortia program of SAE Industries Technology Consortia Programs (SAE ITC), an affiliate of SAE Group. The VRUSC was formed by vehicle, bicycle, ridesharing and technology companies to find technological solutions to rising crashes with pedestrians, bicyclists and others. Royal Oak, MI-based Tome Software founded the Bike-to-Vehicle Advisory Board that grew into the new consortium.

National Highway Transportation Safety Administration data estimates traffic fatalities increased 13% to 7,342 in 2021 versus the prior year, while bicyclist traffic fatalities increased 5%to 1,000during the same window.

BLE connectivity technology creates wireless personal area networks using radio waves in the 2.4-gigahertz band to communicate with other similarly equipped devices. It is already widely available in smartphones and is compatible with SYNC connected vehicle technology without any hardware changes to the vehicle.

BLE could complement other technologies by communicating with other similarly equipped devices with sufficient range for alerts with the potential of advancing safety through awareness of pedestrians, bicyclists and more. BLE also does not rely on line-of-sight detection such as cameras or radar, which means pedestrians and others can be detected while hidden behind obstructions such as buildings. This is especially relevant to the stress of big-city driving on shared roads.

BLE is widely used technology in personal electronics devices, including smartphones, fitness monitoring devices, location-based services, entertainment and much more. It uses very low power with batteries as small as dimes to operate for a very long time. Consumer BLE applications commonly involve pairing two devices. But Fords concept uses BLE as a beacon capable of sensing multiple other similarly equipped devices in range without pairing.

The system interprets a person is using the device, differentiates pedestrians from bicyclists and others based on their traveling speed, and further evaluating risk by their direction. BLE devices rapidly change communications channelsi.e., frequency hoppingin the 2.4 GHz radio band to minimize interference.

Ford and T-Mobile also will demonstrate the Ford app replacing BLE communication with T-Mobiles 5G Advanced Network Solution combined with hyperscale computingwhich adds resources from across a distributed computing network as demand increasesto help create more reliable communications.

T-Mobiles 5G network helps minimize the round-trip data travel time, allowing detection alerts to quickly be delivered to the vehicles SYNC screen.
