Technical solutions are described for providing failsafe assist torque in steering systems. An example method includes determining, by a first controller, a first assist torque signal using a first set of torque sensor signals from a first sensor and a second set of torque sensor signals from a second sensor, the first sensor corresponding to the first controller, and the second sensor corresponding to a second controller. The method further includes determining, by the second controller, a second assist torque signal using the first and second sets of torque sensor signals. Further the method includes generating, by a motor, an assist torque using the first and second assist torque signals, and in response to the first controller receiving a diagnostic signal indicating a failure of the first torque sensor, determining by the first controller, the first assist torque signal using only the second set of torque sensor signals.
