Abstract: The present invention provides an occupant state detection device to which a touchpad and a grip sensor are both provided and in which the grip sensor and the touchpad can operate normally and a computer program. The occupant state detection device comprises: a steering wheel having a touchpad that can be operated using electrostatic capacitance and a grip sensor that detects whether a driver is gripping a rim portion; an operation determination unit that makes an operation determination regarding whether the touchpad is being operated; and a grip determination unit that makes a grip determination regarding whether the rim portion of the steering wheel is being gripped.

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.

Abstract: Providing of a gripping determination system and gripping determination method enabling detecting whether or not the driver is gripping the steering device with higher accuracy.
A gripping determination system that determines a gripping state of a steering device having an electrode on a part of a steering device of a vehicle, includes:



an electrostatic capacitance detecting part that detects electrostatic capacitance of the electrode,
a steering torque sensor that detects steering torque of the steering wheel shaft, and
a determining part that determines whether or not the steering device is being gripped based on detection results of the electrostatic capacitance detecting part and the steering torque sensor.

Abstract: With the steering wheel, steering system, method of controlling steering, and non-temporary computer readable storage media, a grasp detection function can be applied to a steering wheel with a heating function, where one function can contribute to the improvement of the other function. The steering wheel (1) includes a core part (10) to which ground potential is supplied, a first conductor (12) provided on the exterior of the core part (10) and insulated from the core part (10), and a second conductor (14) provided on the exterior of the first conductor (12) and insulated from the first conductor (12) to sense gripping of the steering wheel (1).
