Patent Images
1. A vehicle comprising:
- a steering wheel comprising;
a body;
a wheel;
pillars connecting the wheel to the body;
first sensors disposed on the wheel and facing away from the body; and
second sensors disposed on the wheel and facing the body, each of the first sensors and second sensors forming a group;
a vehicle speed sensor;
a passenger sensor; and
processors configured to;
measure a duration of having a number of hands on the steering wheel by using the first sensors and the second sensors; and
responsive to detecting, via the first sensors and the second sensors, two hands on the steering wheel for a predetermined period, responsive to detecting, via the vehicle speed sensor, that a speed of the vehicle is greater than a predetermined speed, and responsive to detecting, via the passenger sensor, a passenger, grant access to an infotainment system; and
responsive to less than all sensors in the group satisfying a delay threshold, limit access to an infotainment system.

Abstract
Example systems and methods for a driver detection steering wheel are disclosed. An example disclosed vehicle includes a steering wheel, a driver, a detector, and an enabling module. The example steering wheel includes a plurality of capacitive sensors. The example driver is to change voltage levels on the plurality of capacitive sensors. The example detector is to measure time delays corresponding to the plurality of capacitive sensors, and determine a number of hands on the steering wheel based on the time delays. The example enabling module is to, in response to the detector detecting two hands on the steering wheel, grant access to an infotainment system.
