A Torque Interceptor is a device that is designed to remotely turn the steering wheel of a vehicle. This is accomplished through a on the (EPS) torque sensor.

Development has been completed on a 2021 Mazda 3 with a Comma 2 and Comma 3 dev kit. This Torque Interceptor 2 (TI2) is designed to be used with with an 8-wire, SENT-based torque sensor. The TI2 should only be installed in dry environments.

This device has been designed so that the absolute worst-case failure would lead to the loss of power steering while driving. However, most failures would lead to a power steering warning on the vehicle dashboard with no loss of controllability.
