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.
Claims9
An occupant state detecting device, comprising:
- a steering wheel having a touchpad operable using electrostatic capacitance and a gripping sensor for detecting whether a driver is gripping a rim part;
- an operation determining unit for performing operation determination as to whether the touchpad is being operated;
- and
- a grip determining unit for performing a grip determination as to whether the rim part of the steering wheel is being gripped,
- wherein the operation determining unit transmits a first operation determining signal to the grip determining unit when a determination is made that the touchpad is being operated, and
- the grip determining unit suspends grip determination when the first operation determining signal is received.
A non-transitory computer readable recording medium that stores a program for causing a computer to execute a process that performs an operation determination as to whether a touchpad operable using electrostatic capacitance provided on a steering wheel is being operated and a grip determination as to whether the rim part of the steering wheel is being gripped, wherein the grip determination is suspended when the operation determination detects that the touchpad is being operated.
