However they also require that when stopped the doors are kept locked by the application of the brake pedal.
That could be interpreted as disable the electric locks when the brake is pressed. That's how I'd interpret that initially.
However, in general, you can't disable the manual locking mechanism. Is that what they want?
Is it all but the driver's door? That, might make more sense. You don't want the passenger fleeing a vehicle at any stop. You want the passenger to be LET OUT.
The brake method looks like a way to do this automagicly with little inconvience.
Now, when you include the driver's door, you also might prevent carjacking. Some guy reaching in an opened window, open the lock and pull the driver out, carjacking the car.
SO, I see two functions:
1. Disable electric unlock while the brake is pressed and car isn't moving.
2. Engage a solenoid that physically prevents the doors from unlocking when the brake is pressed and the car isn't moving. This includes manually unlocking too.
Child safety usually prevents the rear doors from opening from the inside, correct?
Am I missing something?
