Failsafe detection
First Claim
1. A system for failsafe detection comprising:
- one or more touch sensors determining presence information associated with a number of hands or other appendages an operator of a vehicle has in contact with a steering wheel of the vehicle;
an electronic power steering (EPS) component estimating presence information indicative of whether the operator of the vehicle has hands in contact with the steering wheel of the vehicle; and
a failsafe component;
comparing the presence information of the touch sensors with the presence information of the electronic power steering component; and
generating a component determination for one or more of the touch sensors based on the comparison.

Abstract
Systems and techniques for failsafe detection of vehicle components are provided herein. A system for failsafe detection may include one or more touch sensors determining presence information associated with a number of hands or other appendages an operator of a vehicle has in contact with a steering wheel of the vehicle. The system may include an electronic power steering (EPS) component estimating presence information indicative of whether the operator of the vehicle has hands or other appendages in contact with the steering wheel of the vehicle. The system may include a failsafe component comparing the presence information of the touch sensors with the presence information of the electronic power steering component and generating a component determination for one or more of the touch sensors based on the comparison.

9. A method for failsafe detection comprising:
-
receiving a first reading from a first set of one or more sensors of a steering wheel of a vehicle, the first reading indicative of presence information associated with a number of hands or other appendages an operator of the vehicle has in contact with the steering wheel; receiving a second reading from a second set of one or more sensors of the vehicle; estimating presence information indicative of whether the operator of the vehicle has hands or other appendages in contact with the steering wheel based on the second reading from the second set of sensors; comparing the presence information of the first reading with the presence information of the second reading; and generating a component determination for the first set of sensors or the second set of sensors based on the comparison of presence information between the first reading and the second reading. - View Dependent Claims (10, 11, 12, 13, 14)

15. A system for failsafe detection comprising:
-
one or more touch sensors determining presence information associated with a number of hands or other appendages an operator of a vehicle has in contact with a steering wheel of the vehicle; an electronic power steering (EPS) component estimating presence information indicative of whether the operator of the vehicle has hands or other appendages in contact with the steering wheel of the vehicle by taking readings from one or more torque sensors; and a failsafe component; comparing the presence information of the touch sensors with the presence information of the electronic power steering component; generating a component determination for one or more of the touch sensors based on the comparison; and determining one or more corrective actions for one or more vehicle components based on the component determination and touch sensor dependencies of one or more of the vehicle components. - View Dependent Claims (16, 17, 18, 19, 20)
