Detection of pedestrians and other vulnerable road users

IEE’s intelligent vision sensor, SenseAhead detects pedestrians, vehicles and objects in a vehicle’s driving path and provides crucial input for the Autonomous Emergency Braking (AEB) system.


AEB systems rely heavily on high-tech sensors to accurately detect the vehicle’s surroundings, as they aim to slow the car autonomously in order to avoid or mitigate a collision.

With SenseAhead you have a system specifically designed to detect pedestrians and other vulnerable road users, such as cyclists. It offers improved performance at night - when most accidents with severely or fatally injured pedestrians occur in urban areas.

The sensor uniquely combines a 2D camera with 3D distance measurement based on time-of-flight (TOF) technology. As the 3D component has its own infrared illumination, the sensor’s performance doesn’t rely on other light sources, such as vehicle headlights or street lamps. SenseAhead thereby offers enhanced sensing performance at night, effectively compensating for the shortcomings of a 2D-only system.

AEB systems aimed at mitigating or avoiding vehicle collisions became part of the Euro NCAP rating system in 2014. Pedestrian AEB systems will be incorporated into the rating from 2016 onwards, as a contributing element to the pedestrian protection performance score of the vehicle.
