Overview of EHC Control System
The control philosophy of EHC is to "Initiate a control sequence only when necessary". The
system offers the following advantages:
• The control system operates independently from the vehicle’s engine (no engine driven
hydraulic pump system as per previous self leveling systems).
• Individual control of the rear wheels is possible
• An uneven load is identified and compensated for
• Uneven road surfaces are identified and not compensated for
• Automatic control is interrupted when cornering
• The system is diagnosable using the DIS or MoDiC
The air suspension system consists of the following components:
