Abstract

An intelligent wireless access system for a vehicle comprises a non-transitory computer-readable storage medium having stored thereon a computer program for tracking a target and estimating distance, a position, or direction of the target to a vehicle. The computer program comprises a routine of set instructions for causing the machine to perform receiving a beacon packet from the target, determining signal strength information for the beacon packet, transmitting a message comprising the signal strength information and the beacon packet for the target, and estimating based on received message, at least one of distance, position, or direction of the target to the vehicle.

Claims

1. A method for tracking a target and estimating distance, a position, or direction of the target to a vehicle, the method comprising:

receiving a beacon packet from the target;

determining signal strength information for the beacon packet;

transmitting a message comprising the signal strength information and the beacon packet for the target;

estimating based on received message, at least one of distance, position, or direction of the target to the vehicle; and

controlling an access entry device of the vehicle by either granting access to the vehicle user when the vehicle user is within a range of authorization or denying access to the vehicle user when the vehicle user is outside a range of authorization.

2. The method of claim 1 further comprising performing at least one Passive Entry Passive Start (PEPS) function at the vehicle when the target is within a range of authorization.

3. The method of claim 2 further comprising:

determining any obstacle around the vehicle; and

controlling a camera system of the vehicle responsive to the location of the obstacle.

4. The method of claim 2 further comprising:

retrieving weather information;

controlling a climate control system of the vehicle; and

setting the climate control system if either cooling or heating is required based on the retrieved weather information.

5. The method of claim 2 further comprising:

retrieving vehicle user profile from the target;

identifying vehicle user preference based on prior recorded vehicle user control inputs; and

controlling a climate control system to achieve user comfort responsive to the vehicle user preference.

6. The method of claim 2 further comprising:

retrieving vehicle user profile from the target;

identifying vehicle user preference based on prior recorded vehicle user control inputs; and

controlling an infotainment system to achieve user comfort responsive to the vehicle user preference.

7. The method of claim 1 further comprising transmitting an alert in response to the event responsive indicating a presence of at least one of an occupancy and an intrusion.

8. The method of claim 1, the controlling of the access entry device of the vehicle further comprising:

receiving data defining a first gesture identifier; and

unlocking a door of the vehicle if the vehicle user is within a range of authorization corresponds to the first gesture identifier.

9. The method of claim 8 further comprising:

receiving data from the accelerometer defining a second gesture identifier; and

locking a door of the vehicle if the vehicle user is outside a range of authorization corresponds to the second gesture identifier.

10. A method for tracking a target and estimating distance, a position, or direction of the target to a vehicle, the method comprising:

receiving a beacon packet from the target;

determining signal strength information for the beacon packet;

transmitting a message comprising the signal strength information and the beacon packet for the target;

estimating based on received message, at least one of distance, position, or direction of the target to the vehicle;

receiving a requested schedule time from a second target to pick up the vehicle;

receiving sensor output data representative of a location of the second target; and

transmitting a temporary key having a trigger message to the second target.

11. The method of claim 10 further comprising removing the temporary key from the second target based on, at least in part, (a) the sensor output data, (b) a travel distance to the vehicle, (c) a travel time to the vehicle, and (d) an arrival time to the vehicle is either exceeding the requested schedule time or the second target is out a geo-fence of the vehicle.

12. A method for tracking a target and estimating distance, a position, or direction of the target to a vehicle, the method comprising:

receiving a beacon packet from the target;

determining signal strength information for the beacon packet;

transmitting a message comprising the signal strength information and the beacon packet for the target;

estimating based on received message, at least one of distance, position, or direction of the target to the vehicle;

receiving a request associated with a share event of the vehicle from a second target, the request including a date and time at which the share event to be occurred;

receiving sensor output data representative of a location of the second target; and

transmitting a temporary key having a trigger message to the second target.

13. The method of claim 12 further comprising destructing the temporary key from the second target based on, at least in part, (a) the sensor output data and (b) the share event is either exceeding the request or the second target is out a geo-fence of the vehicle.
