How about taking heat flow into account in the design of a car's electronics?
Heat sources external to the electronic needs not to be taken into account
Electronics an thermal flow are not linked and can be handled separately
Self-heating of electronics does not play a role
No answer ( = 0 points)
Heat sinks external to the electronics need to be taken into account
How about sensors in the design of a car's electronics?
The packaging of many types of sensors often is difficult as they have to be exposed to the environment
Sensor measurements often are taken just once, but are used in many electronics control units(ECUs)
Sensors in automotive electronics arejust about electronics and comprise no other physical domain
No answer ( = 0 points)

What are the advantages of a parallel hybrid concepts for cars?
Energy regeneration from braking
No answer ( = 0 points)
For maximum acceleration, the combustion engine an the alectric motor can be run at a time
Several combustion engines are run in parallel, which improves efficiency
Hydrogen can be burnt without the exhaust gases of classical combustion engines
How about quality in automotive electronics?
Quality topics do not play a role in automotive electronics
The required level in automotive electronics and in communication(e.g. For mobile phones) is the same
For automotive electronics a zero-defect quality level is required
The quality requirements of electronics components rise with the overall complexity of a car
No answer ( = 0 points)
Sneaking tore pressure loss and resulting accidents are a substantial problem in the automotive arena
