摘要： 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 (1) that determines a gripping state of a steering device (2) having an electrode on a part of a steering device (2) of a vehicle, includes:
an electrostatic capacitance detecting part (50) that detects electrostatic capacitance of the electrode,
a steering torque sensor (40) that detects steering torque of the steering wheel shaft (200), and
a determining part (60) that determines whether or not the steering device (2) is being gripped based on detection results of the electrostatic capacitance detecting part (50) and the steering torque sensor (40).-

摘要： 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.
