A method and apparatus for sensing wheel torque of a highly automated driving (HAD) vehicle includes a wheel hub configured to rotate around a rotation axis as the vehicle moves and a brake caliper, including a brake pad, configured to apply a caliper force to the wheel hub. A reaction carriage is interconnected with the brake caliper and is configured to have a reaction force applied to it when the brake caliper applies the caliper force to the wheel hub. The wheel torque sensor includes a hydraulic chamber having a hydraulic fluid and a pressure sensor, interconnected with the hydraulic chamber, that senses pressure applied to the hydraulic fluid in response to the reaction force.
