Advanced Active Cleaning Systems (AACS)

Pioneer for autonomous driving sensor suites

Autonomous driving is a revolution that will profoundly change our mobility. This will require new technologies, most of which require a considerable number of sensors and cameras. For these to function reliably, they must be free of debris to function properly. Röchling Automotive is meeting this challenge with a newly developed, intelligent cleaning concept: the Advanced Active Cleaning System (AACS). The system specifically cleans contaminated areas of the vehicle sensory array. The AACS ensures obstruction free conditions from road debris on the sensors to enable safe and comfortable operation of autonomous vehicles. Thanks to its modular design, the Roechling system gives manufacturers freedom to scale cleaning capability with sensor utilization - for a seamless transition from today to fully autonomous driving.

The most important highlights

The AACS is a complete solution that stores, monitors, doses and, if required, automatically distributes cleaning fluid to several outlets simultaneously or independently.

• Lightweight, injection-molded liquid container with integrated functions:
  • Continuous monitoring of the liquid level
  • Several pump options
  • Safe self-limiting heating system
  • Integrated anti-sloshing features
• Modular distribution system for liquids, optional connection to a Cleaning Control Unit (CCU) or electronic valve/pump controller
• Ice Resistant System

Your customer benefit through our Advanced Active Cleaning Systems

Full freedom of design

• The modular distribution system allows easy adaptation to many different vehicle platforms and the addition of additional ADAS cleaning points. This means: commonality throughout the entire product range

Intelligent fluid management

• With a single pump configuration liquid can be distributed intelligently to different outputs
• Continuous monitoring of the filling levels
• Communication with the vehicle control system to prioritize the cleaning points according to the respective safety objectives
• Various heating/defrosting solutions

Compatible with fully autonomous drive

• The cleaning control unit enables automatic operation of the pump and individual valves – meaning minimum control logic from vehicle control unit is not required

Designed for use in extremely cold environments

• The integrated heater ensures fast system readiness
• Ice Resistant System
