Abstract
A hands-on detection device and a computer program that can simultaneously improve the speed of determining hands-on or hands-off and the accuracy of such determination. A hands-on detection ECU that performs hands-on detection of the rim part by passing a current through a sensor electrode provided on the rim part, hands-on detection being performed using two modes in which the current for the hands-on detection is different.
Claims10
A hands-on detection device that causes current to flow into an electrode provided in a rim part to perform hands-on detection on the rim part, wherein hands-on detection is performed using two modes with different output currents for hands-on detection, wherein the hands-on detection device is configured such that output current flowing out to the electrode differs for each of the two modes, and wherein the hands-on detection device further comprises:
- a hands-on detection part that performs hands-on detection using two modes;
- and
- a switching part that switches modes based on elapsed time from start of causing current to flow,
- wherein the two modes include a first mode that causes a first current to flow and performs grip determination of gripping or non-gripping and a second mode that causes a second current to flow and performs abnormality determination of whether or not an abnormality has occurred.
A hands-on detection device that causes current to flow into an electrode provided in a rim part to perform hands-on detection on the rim part, wherein hands-on detection is performed using two modes with different output currents for hands-on detection, wherein the hands-on detection device is configured such that output current flowing out to the electrode differs for each of the two modes, and wherein the hands-on detection device further comprises:
- a current measuring part for measuring the current of the electrode;
- a hands-on detection part that performs hands-on detection using two modes, the current measuring part having a different amount of gain for the two modes;
- and
- a switching part that switches mode based on current value measured in the current measuring part.
