Abstract
A tire pressure monitoring device can include: a magnetic sensor configured to measure a first magnetic field intensity in a first direction, and to measure second magnetic field intensity in a second direction; and a controller configured to control a state of the tire pressure monitoring device based on a variation of the first magnetic field intensity and a variation of the second magnetic field intensity.
Claims18
A tire pressure monitoring device, comprising:
- a) a magnetic sensor having a first measuring axis configured to measure a first magnetic field intensity in a first direction, and a second measuring axis configured to measure a second magnetic field intensity in a second direction, wherein said first and second magnetic field intensities are measured at a same time and for a certain tire position;
- and
- b) a controller configured to control a state of said tire pressure monitoring device based on a variation of said first magnetic field intensity and a variation of said second magnetic field intensity.
A state control method for a tire pressure monitoring device installed on a circumferential surface of a corresponding tire, the method comprising:
- a) measuring, by a first measuring axis, a first magnetic field intensity in a first direction;
- b) measuring, by a second measuring axis, a second magnetic field intensity in a second direction;
- and
- c) controlling a state of said tire pressure monitoring device according to a variation of said first magnetic field intensity and a variation of said second magnetic field intensity wherein said first and second magnetic field intensities are measured at a same time and for a certain tire position.
