Tips for Driving Safely in the Rain
Heed Your Speed, Keep Your Distance and Know What Features Help by Kathleen Doheny, October 26th, 2015. It's perhaps surprising, but true: Driving on a rainy day is more dangerous…
WRS responds to the increasing demand in securitization
The studies of accidents point out a greater risk on wet roads.
There are many ADAS (Advanced Driver Assistance System) to indicate a lack in adherence of the tyre on the macadam. The car then may automatically adapt the brakes, engine, lights etc
But there is nowadays very few systems to warn before the sliding.
This problematic is a key point for autonomous vehicles
Some sensors detect water on the road using optical absorption phenomena (Marwis®, Road Eye Sensor®…) but they are voluminous and expensive
Some others are on study using the sound (Porsche…) or image recognition (Continental®, Tesla…)
WRS is cost effective, reliable, sensible and specific
WRS detects a wet road. This paramount information enables the driver to adapting his driving (slowing, increasing distance with the car ahead, softening the braking and acceleration…)
WRS is a new market for the equipment manufacturers considering it fits all type of actual vehicles.
It will be essential in the next future for autonomous vehicles.
Technical specs
WRS is a new type of input based on a patented invention.
It is based on a physical measure and needs very few calculation capacity
WRS detects dry, humid or wet road and sends the data to the driver or automatically to the central processor of the car via the busCAN for example.
The system is very sensitive and can detect humidity on the macadam even at very low speed.
1
condition of the road observation
WRS analyses the macadam
2
Detection of wet road and sending of the data
WRS discriminates humid, wet, dry road and sends the data
3
the driver and/or the central processor receives the info
data is received and processed so that the driver and/or the car can adapt the driving
