Abstract
In example implementations, a method is provided. The method includes determining, by a processor, that a vehicle is approaching a door of a building based on a velocity vector of the vehicle, calculating, by the processor, a time of arrival of the vehicle at the door based on the velocity vector of the vehicle and a distance of the vehicle from the door, and controlling, by the processor, the door to begin opening at a time based on the time of arrival and an amount of time for the door to open such that the door is opened when the vehicle arrives at the door.
Claims20
A method, comprising:
- determining, by a processor, that a vehicle is approaching a door of a building based on a velocity vector of the vehicle, wherein the velocity vector is calculated based on data received from at least one sensor, wherein the determining is performed when the vehicle is determined to be within a virtual lane associated with the door;
- calculating, by the processor, a time of arrival of the vehicle at the door based on the velocity vector of the vehicle and a distance of the vehicle from the door;
- and
- controlling, by the processor, the door to begin opening at a time based on the time of arrival and an amount of time for the door to open such that the door is opened when the vehicle arrives at the door.
A system, comprising:
- a door located in a building;
- a motor to control operation of the door;
- a controller communicatively coupled to the motor to control operation of the motor to open and close the door;
- and
- at least one sensor communicatively coupled to the controller to collect movement data of a vehicle, wherein the controller is to begin calculating a velocity vector of the vehicle when the vehicle is determined to be within a virtual lane associated with the door, wherein the velocity vector of the vehicle is calculated based on the movement data and the controller is to cause the motor to begin opening the door at a time based on a time of arrival of the vehicle at the door that is calculated from the velocity vector and a distance of the vehicle from the door, and based on an amount of time for the door to open such that the door is opened when the vehicle arrives at the door.
A non-transitory computer readable storage medium encoded with instructions executable by a processor, the non-transitory computer-readable storage medium comprising:
- instructions to determine that a vehicle is in a virtual lane associated with a door of a building;
- instructions to activate a controller to calculate a velocity vector of the vehicle, wherein the velocity vector is calculated based on data received from at least one sensor;
- instructions to determine that the vehicle is approaching the door;
- instructions to calculate a time of arrival of the vehicle at the door based on the velocity vector of the vehicle and a distance of the vehicle from the door;
- and
- instructions to control the door to begin opening at a time based on the time of arrival and an amount of time for the door to open such that the door is opened when the vehicle arrives at the door.
