TNO developing V2V Cooperative Automatic Emergency Braking system to help prevent accidents with cyclists

Dutch research organization TNO is developing a Cooperative Automatic Emergency Braking system (CAEB) for cars and trucks to help prevent accidents with cyclists, especially at and near junctions. The system relies on vehicle-to-vehicle communication between bikes, cars and trucks.

The system is based on TNO’s intelligent Vehicle Safety Platform (iVSP)—the same platform that enables automatic driving. The iVSP draws on various information sources (radar, communication, map data), seamlessly combining these data with the information gained from vehicle sensors and other information sources (surrounding infrastructure, bikes, pedestrians). With CAEB, the bicycle transmits its own position and speed with the aid of wireless communication, GPS and internal sensors.

Cycling safety
While the number of traffic fatalities in the Netherlands is decreasing, the number of cycling fatalities and critical injuries is showing a slight increase. Statistics show that a car is involved in 80% of cyclist fatalities.
In the Netherlands alone, 8,000 cyclists are admitted to hospital each year following an accident.

This information is combined with data from sensors in the car before being processed and analysed by the in-car iVSP. If the cyclist enters a time-critical zone, the system puts itself on alert.

The system gives the driver visual and audio signals, followed by a tightening of the seatbelt. The car brakes gently at first and then, if the driver does not take action, sharply. In this way the system prevents a collision with the bicycle.

For various reasons, TNO chose the electric bike as the first candidate to be integrated with CAEB. In particular, the electricity needed to power the equipment is available on the bike itself. Moreover, the electric bike is used mainly by seniors; the age group that runs a high risk of becoming involved in a traffic accident while cycling.

Automatic braking, notes TNO, is nothing new. The active safety systems already installed in some cars are equipped with sensors and real-time feedback. However, these systems have their limitations in terms of range and sight lines. Their effectiveness is particularly limited where cyclists or pedestrians are crossing the street.

A cyclist or pedestrian who is about to cross the street outside the range of the sensor(s)—for example, to the rear of a truck—is detected too late or not at all. This presented TNO with the challenge of developing a system that reliably detects, tracks and predicts the most vulnerable participants in traffic—cyclists and pedestrians—especially when they are crossing the street.

I think this was a really good idea. Many motorists completely block out bicycles and motorcycles. I still ride a bicycle some and was riding a dual-sport (on/off-road) motorcycle until 2 years ago when a distracted 19 year old driver pulled a U-turn in my face. He told the police that he did not see until after he turned although it was after dark and I had ridden behind him for more than 1/4 mile with an obnoxiously bright head light that was almost like a flashing light with the soft suspension of the dual-sport motorcycle. Fortunately, I was well dressed and had a race quality full face helmet but I ended up with a fractured neck, back, and hip and a bad wound to the ankle. Four operations later and after 3 months wearing a halo, I am able to walk reasonably and ride my bike but I will never run again.

Hope you continue to recover.

Anyone who has spent time on two wheels will advocate for this feature, it doesn't take long to understand the need.

I hope you find, like many others, that the challenge to prove the diagnosis wrong wins out.

I thought pedestrian/ animal recognition algorithms were more advanced than this which is relying on active notification (although active may be more visible)
In which case there would be even better possibilities from dual tracking systems.

Sooner or latter, human drivers will have to be better assisted and/or replaced to reduce harmful accidents.

Fun driving could be done at the race tracks. It could become another business. Casualties and repairs would be 100% at the drivers expense.
