Detection of a faulty sensor is impossible if there is only one sensor.
If a door is truly suddenly opened when driving then shutting down is a legitimate way to save the passenger. I think they should have 2 door sensors for each door instead of one.
No need 2 sensors. Vehicle controller should be able to determine faulty sensor signal through CANBUS.
The issue here is the way the vehicle determined a faulty door sensor as a safety critical issue, which if following the norm, door sensor should just be Automotive Safety Integrity Level A.
ASIL-A components shouldn't cause vehicle to totally shutdown.
So, if it's true that it's due to door sensor, means BYD architecture on handling faulty sensor is flawed.
If it's not due to door sensor but something worse, BYD is covering up.
Not sure how our authorities will handle.
But if this happens more frequently, especially in EU or US, than the authorities will investigate and BYD might need to issue a fix and recall.
