Abstract
A vehicle seat includes: a pressure sensor capable of measuring a pressure distribution on a surface of the vehicle seat; a plurality of actuators provided in the vehicle seat; and a controller that controls vibrations generated by the plurality of actuators based on the pressure distribution output by the pressure sensor.
Claims18
A vehicle seat, comprising:
- a pressure sensor capable of measuring a pressure distribution on a surface of the vehicle seat;
- a plurality of actuators provided in the vehicle seat;
- and
- a controller that controls vibrations generated by the plurality of actuators based on the pressure distribution output by the pressure sensor,
- wherein the controller invalidates an output of the pressure sensor for a period during which the plurality of actuators generate the vibrations and for a waiting period after the period.

A vehicle seat, comprising:
- a pressure sensor capable of measuring a pressure distribution on a surface of the vehicle seat;
- a plurality of actuators provided in the vehicle seat;
- and
- a controller that controls vibrations generated by the plurality of actuators based on the pressure distribution output by the pressure sensor,
- wherein when a variance value of the pressure distribution is smaller than a first threshold value, and a pressure value in the pressure distribution is equal to or larger than a second threshold value, the controller performs control to increase a strength of vibration of each of the plurality of actuators.

A vehicle seat, comprising:
- a pressure sensor capable of measuring a pressure distribution on a surface of the vehicle seat;
- a plurality of actuators provided in the vehicle seat;
- and
- a controller that controls vibrations generated by the plurality of actuators based on the pressure distribution output by the pressure sensor,
- wherein when a variance value of the pressure distribution is larger than a predetermined value, the controller performs control to increase a strength of a vibration of an actuator among the plurality of actuators which is disposed in a first portion where a pressure value in the pressure distribution is larger than in a second portion.
