Safety
DAI offers rapid activation time without driver intervention. From dry and wet conditions to aquaplaning detection and validation, taking an average time of 80 ms.
DAI outputs will allow OEMs to develop next-generation ADAS+ systems.
Digital Platform for Vehicle Dynamics
Easyrain Digital Platform is a platform hosting virtual sensors to recognize road hazards like:
Water – Snow & Ice – Pothole – Gravel
The virtual sensors analyze existing in-Vehicle information and provide alerts to the vehicle, enabling OEMs to introduce new vehicle safety features.Virtual sensors detecting grip on various surfaces
Digital
Aquaplaning
Information
Recognizes various levels of water on road surfaces.
Digital
Snow
Information
Detection of snow and ice, differentiated from aquaplaning conditions.
Digital
Pothole
Information
Recognizes potholes as well as low-quality roads to provide driver-behavior recommendations.
Digital
Gravel
Information
Identifies low-grip conditions upon gravel.
DAI virtual sensor for Wet Road detection
Digital Aquaplaning Information (DAI) is the first virtual sensor developed within the EDP platform: it detects dangerous wet road conditions and aquaplaning.
The virtual sensor evaluates wet road conditions, works with any tire and can be easily integrated in the vehicle without the need of additional physical sensors.
DAI delivers Level 1, 2, and 3 alert outputs to the vehicle. It is fully configurable with OEMs, activating new vehicle safety features like automatic adjustment of adaptive cruise control speed and distance according to the alert level.
Main Features and Benefits
Function
DAI adjusts to work with any tire without specific calibration, regardless of pressure, wear, and profile. DAI adapts in real time to any vehicle load condition. It is based on the vehicle characteristics and data, like mass, speed, and steering angle.
Integration
The information collected by DAI can be provided through wireless networks to Smart Cities, other vehicles or any other service provides within the network.
Activation
When aquaplaning conditions have been detected,
DAI triggers the AIS anti-aquaplaning system to restore grip and control of the vehicle. DAI output can be used by car manufacturers for new active safety systems.
Possible further Safety measures by vehicle manufacturers
ACC
Automatic adjustment of ACC speed
and safety distance according to warning levels.
Engine cut-off
Automatic vehicle engine torque reduction
for rapid deceleration in case of upcoming hazards.
Safety Belt
Automatic activation of safety belt pre-tensioner
in case of dangerous wet conditions.
No Overtaking
Warning when using indicator lights
in case of dangerous wet conditions to prevent lane change.
Brake Lights
Activate emergency brake lights
to slow down following vehicles.
Seat Vibration
Activate seat or steering wheel vibration
in case of aquaplaning.
