A robust safety system includes
redundancy, fault detection and
diagnosis, fail-safe and fail-operational
mechanisms, safety-critical software,
safety architectures, monitoring and
control, reliable communication protocols,
comprehensive safety analysis, and
adherence to standards such as ISO 26262
(Road Vehicles – Functional Safety)."

Functional safety is arguably the most important
consideration for an engineer when designing
automotive motor control systems. These systems
must be designed to prevent catastrophic failures that
could lead to unintended acceleration or braking.
Ultimately, three main safety goals drive the design
of these systems.
The first goal is preventing over-acceleration and
unintended braking, both of which can result from
faults within the motor control system. For instance,
if the system misinterprets sensor data because of
a fault, it could inadvertently increase the torque,
leading to sudden and unexpected acceleration.
To mitigate this scenario, safety mechanisms
