Configuration data storage for a tire pressure sensor
A tire pressure sensor of a vehicle having a receiver configured to receive, from an Electronic Control Unit (ECU) mounted in the vehicle and having configuration data stored therein, an acknowledgement signal including a request for configuration, and the configuration data; and a controller configured to update the tire pressure sensor with the received configuration data.
1. A tire pressure sensor of a vehicle, comprising:
a receiver configured to receive, from an Electronic Control Unit (ECU) mounted in the vehicle and having configuration data stored therein, an acknowledgement signal including a request for configuration, and the configuration data; and
a controller configured to power up and power down the receiver, and to update the tire pressure sensor with the received configuration data.
2. The tire pressure sensor of claim 1 , wherein:
the controller is configured to power up the receiver for a periodic transmission of pressure data by a transmitter of the tire pressure sensor to the ECU, and
the ECU, in response to receiving the periodic sensor data, transmits to the receiver an acknowledgement signal including a request for configuration if the ECU has new configuration data stored therein.
3. The tire pressure sensor of claim 1 , wherein the tire pressure sensor is configured to communicate with the ECU via a bidirectional communication link.
4. The tire pressure sensor of claim 1 , wherein the receiver is a Bluetooth Low Energy (BLE) receiver.
5. A tire pressure sensor of a vehicle, comprising:
a receiver;
a transmitter configured to transmit to an Electronic Control Unit (ECU) mounted in the vehicle, a tire pressure sensor identification and a ready for configuration signal; and
a controller configured to:
power up the receiver;
determine whether the receiver receives from the ECU, within a predetermined period of time, configuration data stored within the ECU; and
if the tire pressure sensor receives the configuration data, update the tire pressure sensor with the received configuration data.
6. The tire pressure sensor of claim 5 , wherein after the receiver receives the configuration data, the controller is further configured to power down the receiver.
7. The tire pressure sensor of claim 5 , wherein if the receiver does not receive the stored configuration data, the transmitter is configured to transmit to the ECU pressure data.
8. The tire pressure sensor of claim 5 , wherein the controller is configured to power up the receiver and transmit to the ECU the tire pressure sensor identification and the ready for configuration signal on a periodic basis.
9. A method for updating configuration data in a tire pressure sensor of a vehicle, comprising:
receiving, from the Electronic Control Unit (ECU) by a receiver of the tire pressure sensor, an acknowledgement signal including a request for configuration; and
transmitting, by a transmitter of the tire pressure sensor to the ECU, a ready for configuration signal,
receiving, by the receiver of the tire pressure sensor, from the ECU mounted in the vehicle and having configuration data stored therein, the configuration data; and
updating, by a controller of the tire pressure sensor, tire pressure sensor with the received configuration data.
10. The method of claim 9 , further comprising:
powering up the receiver prior to the receiver receiving from the ECU the acknowledgement signal including the request for configuration; and
powering down the receiver after the receiver receives from the ECU the configuration data.
11. The method of claim 9 , further comprising:
powering up the receiver for a periodic transmission of pressure data by a transmitter of the tire pressure sensor to the ECU; and
in response to receiving the periodic sensor data, transmitting by the ECU to the receiver an acknowledgement signal including a request for configuration if the ECU has new configuration data stored therein.
12. A Tire Pressure Monitoring System (TPMS), comprising:
an Electronic Control Unit (ECU) mounted in a vehicle and having configuration data stored therein; and
a tire pressure sensor, comprising:
a receiver configured to receive, from the ECU, and acknowledgement signal including a request for configuration, and the configuration data; and
a controller configured to power up and power down the receiver, and to update the tire pressure sensor with the received configuration data.
13. The TPMS of claim 12 , further comprising a plurality of the tire pressure sensors.
14. The TPMS of claim 12 , wherein the ECU is configured to receive the configuration data to be stored therein from an external configuration controller.
15. The TPMS of claim 12 , wherein the ECU is configured to receive the configuration data to be stored therein from an external configuration controller via a wireless connection.
16. The TPMS of claim 12 , wherein the ECU is configured to receive the configuration data to be stored therein from an external configuration controller via a cable connection.
17. The TPMS of claim 12 , wherein the ECU is configured to receive the configuration data to be stored therein via the Internet.
