Abstract

Systems and methods for control systems for facilitating situational awareness of a vehicle are provided. Sensors located around a stationary vehicle may detect moving objects that pose potentially dangerous situations for the vehicle occupants and for the object. This can cause the doors to lock automatically in order to make the situation safer. Additionally, electromagnetic radiation sensors located around the vehicle may detect the lights and sounds of emergency vehicles. If the electromagnetic data from the electromagnetic radiation sensors match a known pattern of electromagnetic data emitted by emergency vehicles stored in a library an alarm may be sounded through the speakers of the vehicle in order to alert the vehicle occupants of an emergency vehicle in the vicinity.

Claims

1. An automatic door-locking system for a vehicle comprising:

a sensor adapted to detect the movement of objects in the immediate vicinity exterior to the vehicle while the vehicle is stationary;

a computer processor adapted to analyze the data from the sensor to determine if a movement threshold of an object has been reached;

a switch operatively coupled to the computer processor and adapted to send a signal to the computer processor to control an actuator to engage or disengage a door lock of a door of the vehicle; and

an automatic door-locking mechanism adapted to activate when an outcome of the data analysis is over the movement threshold resulting in the computer processor sending one or more signals to activate the actuator to lock the door and disable the switch associated with the door.

2. The system of claim 1, further comprising a plurality of sensors adapted to detect the movement of objects in the immediate vicinity exterior to the vehicle while the vehicle is stationary.

3. The system of claim 2, wherein the immediate vicinity exterior to the vehicle is comprised of a plurality of zones with each zone assigned to one or more door locks of the vehicle.

4. The system of claim 3, wherein each zone is associated with at least one sensor and a field-of-view of the sensor defines the zone, and each of the doors is associated with one or more of the zones.

5. The system of claim 1, wherein the computer processor is further adapted to:

calculate, from the sensor data, the velocity of the object, the distance the object is from the stationary vehicle, the size of the object, and the direction vector of the object; and

determine a movement threshold that is based upon the velocity of the object, the distance the object is from the stationary vehicle, and the direction vector of the object.

6. The system of claim 5, wherein the movement threshold of an object comprises an object that has a non-zero velocity, is moving in a direction towards the vehicle, and is at a certain maximum distance away or less from the vehicle.

7. The system of claim 1, wherein the immediate vicinity exterior to the vehicle is comprised of a plurality of zones with each zone assigned to one or more door locks of the vehicle, and the computer processor is further adapted to:

send a first signal to the actuators to engage the door locks of the doors associated with the one or more zones in which the moving object was detected;

automatically lock one or more door locks that are unlocked if the outcome of the data analysis is over the movement threshold;

disable one or more switches for the door locks in order to prevent one or more vehicle occupants from unlocking any locked doors that were locked as a result of the outcome of the data analysis being over the movement threshold; and

notify vehicle occupants that certain doors have been automatically locked and certain switches for the door locks have been disabled in order to maintain safety inside and outside of the vehicle.

8. The system of claim 7, wherein the computer processor is further adapted to:

continue to receive data from the sensor;

continue to analyze the data from the sensor to determine whether the movement threshold has been reached;

send a second signal to at least one zone in order to automatically unlock one or more locked door locks that were originally unlocked prior to when the threshold value was reached if the outcome of the data analysis falls below the movement threshold;

enable the use of the switches for the door locks; and

notify the vehicle occupants that doors are no longer being automatically locked and the switches for the door locks are re-enabled.

9. A method for automatically locking the doors of a vehicle, the method comprising:

receiving sensor data from a vehicle-mounted sensor;

analyzing the sensor data to identify movement of objects in the immediate vicinity exterior to the vehicle while the vehicle is stationary;

determining, based upon the analyzing, if a movement threshold value for objects exterior to the vehicle has been reached; and

activating an automatic door-locking mechanism when the outcome of the data analysis is over the movement threshold resulting in a computer processor sending one or more signals to activate an actuator to lock a door of the vehicle and disable a switch associated with the door and operatively coupled to the computer processor, wherein the switch is adapted to send a signal to the computer processor to control the actuator to engage or disengage the door lock.

10. The computer implemented method of claim 9, wherein receiving sensor data comprises receiving data from a plurality of sensors.
