Abstract

A vehicle including a first aerodynamic device extending from a body of the vehicle and movable between an extended position and a retracted position and an aerodynamic control module configured to determine wind conditions during forward movement of the vehicle and to move the first aerodynamic device between the extended position and the retracted position based on the determined wind conditions.

Claims (46)

1 . A vehicle comprising:

a first aerodynamic device extending from a body of the vehicle and movable between an extended position and a retracted position;

an on-vehicle sensor;

data processing hardware; and

memory hardware in communication with the data processing hardware and storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations, the operations comprising an aerodynamic control module configured to:

determine, using the on-vehicle sensor, current wind conditions during forward movement of the vehicle, wherein the current wind conditions comprise a wind direction and a wind magnitude;

confirm, using remotely obtained weather data, the current wind conditions;

determine that the current wind conditions are sustained; and

based on the current wind conditions being confirmed and sustained, move the first aerodynamic device between the extended position and the retracted position based on the current wind conditions.

2 . The vehicle of claim 1 , wherein the first aerodynamic device is a tire deflector.

3 . The vehicle of claim 1 , wherein the first aerodynamic device is a spoiler.

4 . The vehicle of claim 1 , further comprising a second aerodynamic device extending from the body of the vehicle and movable between an extended position and a retracted position.

5 . The vehicle of claim 4 , wherein the second aerodynamic device is operable between the extended position and the retracted position independent of the first aerodynamic device.

6 . The vehicle of claim 5 , wherein the aerodynamic control module is configured to move the second aerodynamic device between the extended position and the retracted position based on the current wind conditions.

7 . The vehicle of claim 1 , wherein the first aerodynamic device is movable into a plurality of positions relative to the body between the extended position and the retracted position.

8 . A vehicle comprising:

a first tire deflector extending from a body of the vehicle proximate to a first tire located on a driver side of the vehicle and movable between an extended position and a retracted position;

a second tire deflector extending from the body of the vehicle proximate to a second tire located on a passenger side of the vehicle and movable between an extended position and a retracted position;

an on-vehicle sensor;

data processing hardware; and

memory hardware in communication with the data processing hardware and storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations, the operations comprising an aerodynamic control module configured to:

determine, using the on-vehicle sensor, current wind conditions during forward movement of the vehicle, wherein the current wind conditions comprise a wind direction and a wind magnitude;

confirm, using remotely obtained weather data, the current wind conditions;

determine that the current wind conditions are sustained; and

based on the current wind conditions being confirmed and sustained:

move the first tire deflector and the second tire deflector into the extended position during a headwind condition; and

move one of the first tire deflector and the second tire deflector into the extended position and the other of the first tire deflector and the second tire deflector into the retracted position in a crosswind condition.

9 . The vehicle of claim 8 , wherein the on-vehicle sensor comprises at least one of a radar sensor or an ultrasonic sensor.

10 . The vehicle of claim 8 , wherein;

the on-vehicle sensor is in communication with the aerodynamic control module; and

the aerodynamic control module is configured to differentiate between the headwind condition and the crosswind condition based on information received from the on-vehicle sensor.

11 . The vehicle of claim 8 , further comprising a spoiler extending from the body of the vehicle and including a first end and a second end.

12 . The vehicle of claim 11 , wherein the aerodynamic control module is configured to move the first end and the second end between a first position extending from a surface of the body and a second position adjacent to the surface of the body.

13 . The vehicle of claim 12 , wherein the aerodynamic control module is configured to move the first end and the second end independently from one another.

14 . The vehicle of claim 12 , wherein the aerodynamic control module is configured to move the first end and the second end between the first position and the second position based on the vehicle experiencing the headwind condition or the crosswind condition.

15 . A system comprising:

data processing hardware; and

memory hardware in communication with the data processing hardware and storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations, the operations comprising:

determining, using an on-vehicle sensor of a vehicle, current wind conditions during forward movement of the vehicle, wherein the current wind conditions comprise a wind direction and a wind magnitude;

confirming, using remotely obtained weather data, the current wind conditions;

determining that the current wind conditions are sustained; and

based on the current wind conditions being confirmed and sustained, adjusting at least one aerodynamic device based on the current wind conditions.

16 . The system of claim 15 , wherein the at least one aerodynamic device includes a tire deflector.

17 . The system of claim 16 , wherein the at least one aerodynamic device includes a spoiler.

18 . The system of claim 17 , wherein the tire deflector and the spoiler are moved between an extended position extending from a body of the vehicle and a retracted position based on the current wind conditions.

19 . A vehicle incorporating the system of claim 15 .
