AUTOMOTIVE MECHATRONICS 2
MechatronicsSynergetic use of several engineering disciplines
Modern way to design ‘‘helpful machinery’’
The tasks of the machinery should be realized in the most efficient way, be it mechanically, electronically, or by software.
The functions required can be implemented into the available space at a reasonable price.

MechatronicsIntegration:
The most suitable technology for every function.Sensotronic, electronics and mechanics.Smaller sizeLesser hardwareCheaper production cost Increased requirements on environmental
conditions
ComplexityMore actuators and sensors.Information processing (pattern recognition
algorithms)High speed, deterministic, hierarchical
communication systems (BUS Systems)

AUTOMOTIVE MECHATRONICS 5
Mechatronic systems in vehiclesAnti-blocking system (ABS) and electronic stability program (ESP)
Reduce driving accidents
Active body control (ABC) system Controls the body vibrations caused by road roughness.
Manual transmissions are being automated with complex actuator and sensor systemsGive similar shifting comfort with a higher efficiency
Headlamps are turned on and off according to light conditions
Adaptive airbag deployment

Better functionality
Better use of space
Lower number of interfaces
Smaller cost for a given performance.
Requires a function-oriented design approach
The best suited technologies available.
Engineers of the different disciplines
Teamwork
Use of tools to link the technologies together
