Abstract: A program and a control device capable of calibrating a detection value of a sensor that detects contact with a steering wheel are provided. The program in accordance with the present invention is characterized by causing a computer to execute processing of distinguishing whether or not a user is on a driver's seat of a vehicle; acquiring, from a sensor (21) that converts contact with a steering wheel (2) into an electric signal for detection, a detection value of the detected electric signal; determining whether or not a difference between the detection value acquired when it has been distinguished that the user is not on the driver's seat, and a reference value is equal to or larger than a threshold value; and setting the detection value as the reference value when it has been determined that the difference is not equal to or larger than the threshold value.

Abstract: An occupant information sensing device 100 includes a plurality of heater electrodes that are provided at a vehicle steering wheel 104 and insulated and separated from one another and that generate heat by conduction. Power sources provide electrical current for heater electrodes. Electrical circuit elements enable the system to provide occupant biological condition monitoring, gripping detection, and electrical stimulation. The circuits enable common electrical connecting to the heater electrodes to provide multiple functions through the use of filtering and time division multiplexing.
