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.
Claims13
A gripping determination system that determines a gripping state of a steering device, having an electrode on a part of the steering device of a vehicle, the gripping determination system comprising:
- a first detecting part for detecting electrostatic capacitance at the electrode;
- a second detecting part for detecting steering torque of a steering wheel shaft;
- and
- a determining part for determining whether or not the steering device is gripped based on the detecting results of the first detecting part and the second detecting part, wherein the steering device includes a rim part that a driver can grip and spokes extending from near a center of the steering device toward the rim part, and the electrode is provided in a base part of a spoke part, and wherein an operating part for operating on-vehicle devices is provided on the spoke part and the electrode is provided on a decorative member provided on the operating part.
A gripping determination method for using an electrode provided on a part of a vehicle steering device for determining gripping state of the steering device, comprising:
- acquiring detection results from a first detecting part for detecting electrostatic capacitance of the electrode;
- acquiring detection results from a second detecting part for detecting steering torque of a steering wheel shaft;
- and
- determining whether or not the steering device is being gripped based on the detection results of the first detecting part and the second detecting part, wherein the steering device comprises a rim part that a driver can grip and spokes extending from near a center of the steering device toward the rim part, wherein the electrode is provided in a base part of a spoke part, and wherein an operating part is provided on the spoke part and the electrode is provided on a decorative member provided on the operating part.
