Abstract: 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.

Abstract: A dual tire pressure monitoring system (TPMS) and wheel torque sensor system generates a single wireless signal containing both tire pressure data and wheel strain data. The wheel strain data is functionally related to wheel torque. The dual sensor has a transceiver that generates the wireless signal for a remote controller. A body of the dual sensor is positioned on the interior of the wheel under the tire, near the valve stem. The wheel torque is used to control braking, propulsion or steering of a Highly Automated Driving (HAD) vehicle, and to improve vehicle stability control and vehicle diagnostics.

Abstract: A method and system for updating geoinformatic data. In one example, the method includes determining, with an electronic processor, a geographic area of interest and determining whether a vehicle is within the geographic area of interest based on a location signal received from the vehicle. The method also includes transmitting to the vehicle a request to upload sensor data and receiving the sensor data from the vehicle. A portion of the geoinformatic data is updated within a map database based on the sensor data. The portion is associated with the geographic area of interest.
