Automotive electronics
Automotive electronics encompasses the entire field of electronics in motor vehicles . This includes the control units that are distributed in the vehicle. The electronics in the vehicle are subject to special requirements in terms of robustness, temperature range, vibration and shock resistance and reliability . The development of control devices has developed rapidly since the 1990s along with the increase in the performance of microprocessors .
Examples of electronic applications in vehicles
- Instrument cluster (used to display the data in the car)
- Engine control with activation of the ignition system or the injection system
- Anti-lock braking system and vehicle dynamics control
- Airbag (electronics detect collision and trigger the airbag)
- Body control unit
- Driver assistance systems
- Car alarm systems
- Multimedia devices ( navigation system , TV tuner, etc.)
Data communication between the control units
In the meantime, more than 20 control units are distributed in every new mid-range model, which communicate with each other via CAN bus , LIN bus or other vehicle-specific bus systems . In the full expansion of the upper-class segment, the importance of automotive electronics is particularly evident - there you can sometimes find up to 80 control units, 3000 m of cables and 3800 contacts. However, it is this complexity of today's vehicles that repeatedly causes breakdowns and malfunctions.
Requirements for electrical components
Electronic components for motor mounting must be specified for a temperature range of −40 to 125 ° C. For other areas such as the interior, a temperature range of −40 to 85 ° C is specified. Many chip manufacturers have their own category for ICs that can be used in automotive engineering.
