Abstract
A tire pressure monitor can include: a wireless transmitting port wirelessly coupled to a first air pressure sensor arranged inside of a tire of a vehicle, where the wireless transmitting port is configured to receive an internal air pressure from the first air pressure sensor; and a controller coupled to the first wireless transmitting port, where the controller is configured to determine a current tire pressure in accordance with a difference between the internal air pressure and an external air pressure outside of the tire. voltage signals, and an output terminal for
Claims9
A method of monitoring tire pressure, the method comprising:
- a) determining an external air pressure outside of a tire of a vehicle;
- b) monitoring an internal air pressure inside of said tire;
- and
- c) determining, by a controller, a current tire pressure of said tire in accordance with a difference between said internal air pressure and said external air pressure.
A tire pressure monitor, comprising:
- a) a wireless transmitting port wirelessly coupled to a first air pressure sensor arranged inside of a tire of a vehicle, wherein said wireless transmitting port is configured to receive an internal air pressure from said first air pressure sensor;
- and
- b) a controller coupled to said first wireless transmitting port, wherein said controller is configured to determine a current tire pressure in accordance with a difference between said internal air pressure and an external air pressure outside of said tire.
