Pump
The time required to recharge the accumulators is defined by the pump design. A short recharge time requires a powerful pump, while for standard setups the pump can be optimized for size and weight.
Aquaplaning Intelligent Solution
Anti-aquaplaning System
After years of research and analysis, we have developed the first active system capable of eliminating aquaplaning, restoring grip and enhancing safety in wet road conditions, by means of a jet of water.
Main Features and Benefits
Safety
Immediate activation without driver intervention
High speed reaction time:
less than 80 ms in emergency conditions
Function
In aquaplaning conditions, AIS immediately restores adherence with a high pressure water jet
AIS reduces the stopping distance by 20% regardless of tire wear, tire size and tire pressure
Integration
AIS can be integrated on vehicles independent of vehicle drive, vehicle size, as well as human/autonomous driving
Car manufatures can customize AIS
based on trade-offs between space available, performance and product cost
The components of the complete AIS system
High pressure pump: Designed to deliver fluid pressure up to 140bar.
Proprietary design owned by Easyrain.
Pressure accumulators: Used to store water under pressure.
Wide range of customizations possible (size, material, etc.).
Injection system: Designed to spray fluid at high pressure from the accumulators.
Electric Valves for fast activation response.
Fixed or telescopic solutions to adapt to different vehicle ground clearances.
Windshield washer fluid tank (series installation): Used instead of adding an additional water reservoir, to save weight.
At 110 km/h, fluid consumption is 0,3 liters per 30 meters traveled in aquaplaning.
Antifoam: Preventing the generation of foam from detergent of windshield washer fluid.
Patented fluid added to the washer fluid.
ADAS Sensors Cleaning valve (opt.)::
Valve used to provide pressurized water for sensor cleaning (legal requirements for ADAS systems).
Modular and customizable components
AIS is highly modular and customizable depending on the OEMs’ targets.
We offer one, two or more accumulators’ setups with different volumes and materials to deliver the best performance.
Accumulators
OEMs can customize the system according to packaging constraints and spray-time duration. Various configurations of accumulators are available at different volumes and weights for the set-up of one or two accumulators to optimize. performance.
Injectors
Fixed and telescopic injectors are selected based on vehicle configuration and ground clearance: Easyrain can provide specific injectors for sedans, supercars, SUVs, etc…
Valve
The component on the left portrays the current layout with industrial brass valve. On the right, is the new valve concept: an electromagnetic controlled device approximately 3x lighter than previous layout.
AIS weight and performance as design criteria
Using the above-mentioned prototype criteria, the system can be designed for low cost or low weight.
Any other performance related design criteria can be applied to the overall system leading to further configurations.
Examples of configurations
Reference
layout
Two 0,56 Lt of water accumulators serving 2 injectors through two lateral valves, to enhance optimization between weight, cost, and performance: 3,5 seconds of continuous time when activated on both wheels at the same time.

cleaning valve
Two 0,56 Lt of water accumulators serving 2 injectors through two lateral valves, with optional ADAS Sensors Cleaning valve to provide pressurized fluid for sensor cleaning.
Mono
channel
Two 0,56 Lt of water accumulators serving 2 injectors through single over-center valve, for cost optimization.
One accumulator
long spray time
One 1,36 Lt of water accumulator serving 2 injectors through two lateral valves, for extended spraying performance time: 4,5 seconds of continuous time when activated on both wheels at the same time, 1 second more than reference layout.
One accumulator
normal spray time
One 0,91 Lt of water accumulator serving 2 injectors through two lateral valves, for cost optimization depending on vehicle platform architecture and space availability in the engine bay.
