Abstract

In at least one embodiment, an apparatus includes a controller coupled to a first sensor positioned on a first object external to a vehicle and configured to receive first information indicative of a height of the first object from the first sensor via Bluetooth Low Energy (BLE) and store second information corresponding to a height of the vehicle. The controller is further configured to receive third information corresponding to a height of overhead obstacle positioned external to the vehicle and to compare at least one of the first information and the second information to the third information. The controller is further configured to generate an alert based on the comparison of the at least one of the first information and the second information to the third information.

First claim

What is claimed is:

1. An apparatus comprising:
a memory device; and
a controller including the memory device and being electrically coupled to a first sensor positioned on a first object external to a vehicle, the controller being configured to:
receive first information indicative of a height of the first object from the first sensor via Bluetooth Low Energy (BLE);
store second information corresponding to a height of the vehicle;
receive third information corresponding to a height of an overhead obstacle positioned external to the vehicle;
compare at least one of the first information and the second information to the third information; and
generate an alert based on the comparison of the at least one of the first information and the second information to the third information,

wherein the controller is further configured to receive an advertisement signal including an identification for the first sensor via BLE prior to receiving the first information,
wherein the controller is further configured to determine whether the advertisement signal was previously received from the first sensor in a current drive cycle based on the identification, and
wherein the controller is further configured to prompt a user to add a second sensor for a second object and to provide additional information indicative of a second height for the second object in response to the controller determining that the advertisement signal was not previously received from the first sensor.

2. The apparatus of claim 1 wherein the first information is also indicative of at least one of an object type for the first object, a location of the first object in reference to the vehicle, and manufacturer specific data of the first object.

3. The apparatus of claim 1 wherein the controller is further configured to determine whether the height of the first object as currently received from the first sensor is equal to the height of the first object as previously received from the first sensor.

4. The apparatus of claim 3 wherein the controller is further configured to store the height of the first object as currently received from the first sensor in a persistent object metadata database for storage in a subsequent key ignition cycle.

5. The apparatus of claim 1 wherein the controller is further configured to receive at least side object information and steering wheel angle information to monitor for the overhead obstacle that is positioned on one of a left side, a right side, and a rear side of the vehicle.

6. The apparatus of claim 1 wherein the controller is further configured to receive via BLE, fourth information corresponding to a height of a second object that is positioned external to the vehicle.

7. The apparatus of claim 6 wherein the controller is further configured to compare the first information to the fourth information prior to comparing the at least one of the first information and the second information to the third information.

8. A method comprising:
electrically receiving, via Bluetooth Low Energy (BLE), first information indicative of a height of an object from a sensor positioned on the object that is external to a vehicle;
electrically storing second information corresponding to a height of the vehicle;
electrically receiving third information corresponding to a height of an overhead obstacle positioned away from the vehicle;
electrically comparing at least one of the first information and the second information to the third information;
electrically generating an alert based on the comparison of the at least one of the first information and the second information to the third information;
receiving an advertisement signal including an identification for the sensor via BLE prior to receiving the first information;
determining whether the advertisement signal was previously received from the sensor in a current drive cycle based on the identification;
determining whether the height of the object as currently received from the sensor is equal to the height of the object as previously received from the sensor; and
storing the height of the object as currently received from the sensor in a persistent object metadata database for storage and retrieval in a subsequent key ignition cycle.

9. The method of claim 8 wherein the first information is also indicative of at least one of an object type for the object, a location of the object in reference to the vehicle, and manufacturer specific data of the object.

10. The method of claim 8 further comprising electrically prompting a user to add a first sensor for a first object and to provide additional information indicative of a first height for the first object in response to determining that the advertisement signal was not previously received from the sensor.

11. The method of claim 8 further comprising electrically receiving at least side object information and steering wheel angle information to monitor for the overhead obstacle that is positioned on one of a left side and a right side of the vehicle.
