It sounds like it also may cause damage to other electronic components.
They essentially switch the alternator into different mode that doesn't limit the output voltage in order to generate as much energy as possible.
I can't imagine them running a separate wire in the harness only for this one feature. It makes more sense to simply increase the voltage of the 'mains' 12V power inside the car, dump as much energy into it as possible, and design all critical components to handle the event gracefully.
Sacrificing the less important electronics sounds like a viable option during a rollover event.
- lkjasldkjf 10y agoAutomotive components are already designed to be very robust to input voltage transients. Here's an interesting paper on the conditions automotive electronics are exposed to, including very high voltages during a load dump: http://www.ti.com/lit/an/snva681a/snva681a.pdf http://www.ti.com/lit/an/snva681a/snva681a.pdf
