1. A computer comprising a memory and a processor storing instructions executable by the processor such that the computer is programmed to:
- receive from a wearable portable device, mobile movement data representing movement of the wearable portable device;
identify, from the mobile movement data, a vibrational torque signal including a periodic component, the periodic component corresponding to a vibration of a steering wheel during driving and transmitted by the steering column to the steering wheel; and
determine that a hand of a user is on the steering wheel based at least in part on the periodic component of the vibrational torque signal from the mobile movement data.

Abstract
Data representing movement of a portable device is received. A vibrational torque signal within that data corresponding to the vibration of a steering wheel is identified. Based at least in part on the identification, it is determined that a user has a hand on the steering wheel.
