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.

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
