of which will be the fi rst to market with the technology in 2021,” adds Sundaram. “We foresee that the Euro NCAP
assessment will positively impact the timely application of such technologies. Traditionally, crash safety ratings have been based on the physical performance of cars during collisions, but software is now taken into consideration. We anticipate that ratings will be boosted in cars that provide 5G-driven pedestrian alert systems, which will in turn accelerate manufacturer adoption.” The method for alerting the driver
will be specifi ed by the individual OEM, with Harman having explored diff erent options such as visual cues in the vehicle’s head-up display and providing haptic feedback via the steering wheel. At the 2020 Consumer Electronics Show (CES) it demonstrated a concept of how the technology could provide alerts via a fl exible glass dashboard panel. In the future, there’s the opportunity
for the person carrying the 5G device to also receive a warning, such as an alert tone or vibration, but this is still in development. “At present, we are focused on the automotive element of the technology and ensuring the driver

is alerted and has the opportunity to react accordingly,” says Sundaram. “With the support of Samsung, we are looking at how this technology could pair with smartphones initially, as well as other 5G-enabled devices such as headphones and wearables later in the decade.” As part of Harman’s ExP Integrated
Solution Suite, which provides in-car connectivity, safety and entertainment features, vehicle-to- pedestrian technology is currently a
passive safety system that forewarns the driver of potential collisions. Sundaram concludes, “The fi rst wave of vehicle-to-pedestrian technology implementation, until around 2025, will be a passive safety warning and won’t control the vehicle. This will then progressively be integrated with the vehicle’s braking system to automatically bring the car to a stop if a safety confl ict arises. This will be a signifi cant step towards autonomous vehicles.” ●
