A process for controlling an electric motor is disclosed. The process includes determining a target torque to be delivered by the electric motor, associating the target torque with a control target for a control input of the electric motor according to a mapping between the target torque and the control target, acquiring a feedback signal of the control input, controlling the electric motor with an error between the feedback signal and the control target, identifying a critical condition where the error diverges, determining a safety control target corresponding to a safety target torque according to the mapping, where the safety target torque is reduced relative to the target torque, and replacing the error when the critical condition is identified with a safety error between the feedback signal and the safety control target.
