▪ Decoupling of the diesel engine from the user input
▪ Dependent on the demand of the subsystems
▪ Engine speed control strategies:
▪ Quasi-constant, low speed
▪ Optimum speed in terms of load and efficiency map
Higher engine power capacity, lower losses

Functional Safety
Independent metering for power assisted steering systems
• electrical drives offer very often integrated safety functions
• leads to an easy system integration for OEM
• benefits of IM structures in steering systems:
• driver assisted steering
• high safety level due to extended control intervention
