Activation of tire pressure measurement systems
Method and apparatus are disclosed for activation of tire pressure measurement systems. An example vehicle includes a door including a handle sensor, a tire pressure measurement system (TPMS) sensor, a communication module, a display, and a controller. The controller is to activate the TPMS sensor responsive to detecting, via the handle sensor, engagement of a handle and collect, via the communication module, a measurement from the TPMS sensor upon activation. The controller also is to present, via the display, a low-pressure alert in response to determining the measurement is less than a threshold.
1. A vehicle comprising:
a door including a handle sensor;
a tire pressure measurement system (TPMS) sensor;
a communication module;
a display; and
a controller to:
activate the TPMS sensor upon identifying at least one of an upcoming scheduled start or an upcoming predicted start for a vehicle engine;
activate the TPMS sensor responsive to detecting, via the handle sensor, engagement of a handle;
collect, via the communication module, a measurement from the TPMS sensor upon activation before a vehicle engine is started, wherein the TPMS sensor communicates with the communication module at a reduced rate before vehicle tires are in motion; and
present, via the display, a low-pressure alert in response to determining the measurement is less than a threshold.
2. The vehicle of claim 1 , wherein the controller presents, via the display, a high-pressure alert in response to determining the measurement is greater than a second threshold.
3. The vehicle of claim 1 , wherein the controller is configured to activate, localize, collect measurements from, and present low energy alerts based on a plurality of TPMS sensors for a respective plurality of vehicle tires.
4. The vehicle of claim 1 , wherein the communication module communicates with the TPMS sensor via a Bluetooth® low-energy communication protocol to collect the measurement from the TPMS sensor.
5. The vehicle of claim 1 , further including a temperature sensor, wherein the controller is configured to activate the TPMS sensor responsive to the temperature sensor detecting a decrease in temperature over a predetermined period of time that exceeds a temperature change threshold.
6. The vehicle of claim 1 , wherein the controller is configured to activate the TPMS sensor responsive to the communication module receiving a car-finder signal from a mobile device of a user.
7. The vehicle of claim 1 , wherein the controller is configured to activate the TPMS sensor responsive to the communication module receiving at least one of a remote start signal and a remote unlock signal from a mobile device of a user.
8. A vehicle, comprising:
a door including a handle sensor;
a door-ajar sensor;
a tire pressure measurement system (TPMS) sensor; a communication module;
a display; and
a controller to:
activate the TPMS sensor responsive to the door-ajar sensor detecting that the door is opening;
activate the TPMS sensor responsive to detecting, via the handle sensor, engagement of a handle;
collect, via the communication module, a measurement from the TPMS sensor upon activation; and
present, via the display, a low-pressure alert in response to determining the measurement is less than a threshold.
9. The vehicle of claim 8 , wherein the controller is configured to collect the measurement from the TPMS sensor before a vehicle engine is started.
10. The vehicle of claim 9 , wherein the TPMS sensor communicates with the communication module at a reduced rate before vehicle tires are in motion.
11. The vehicle of claim 8 , wherein, to activate the TPMS sensor and collect the measurement from the TPMS sensor, the controller is configured to:
send a low-frequency wake-up signal to the TPMS sensor via the communication module;
establish Bluetooth® low-energy communication between the communication module and the TPMS sensor upon the TPMS sensor receiving the low-frequency wake-up signal;
send an instruction to the TPMS sensor via the Bluetooth® low-energy communication to collect the measurement; and
receive the measurement from the TPMS sensor via the Bluetooth® low-energy communication.
12. The vehicle of claim 8 , wherein the controller is configured to send, via the communication module, a signal to a mobile device of a user to present at least one of the measurement and the low-pressure alert via the mobile device.
13. The vehicle of claim 8 , further including a keypad of the door, wherein the controller is configured to activate the TPMS sensor responsive to the keypad receiving a passcode.
14. The vehicle of claim 8 , further including a liftgate and a liftgate sensor, wherein the controller is configured to activate the TPMS sensor responsive to the liftgate sensor detecting a request to open the liftgate.
15. A vehicle, comprising:
a door including a handle sensor;
a tire pressure measurement system (TPMS) sensor;
a communication module;
a display; and
a controller to:
activate the TPMS sensor responsive to detecting, via the handle sensor, engagement of a handle;
activate the TPMS sensor responsive to detecting that a mobile device of a user is within a threshold distance for passive entry into a vehicle cabin;
activate the TPMS sensor responsive to the communication module receiving a signal from a nearby garage door communication module indicating that a garage door is opening;
collect, via the communication module, a measurement from the TPMS sensor upon activation; and
present, via the display, a low-pressure alert in response to determining the measurement is less than a threshold.
