Abstract

Two or more sensors positioned at a wheel of a stopped vehicle may detect an unwanted substance, and transmit signals, based on which a height level of the substance is determined. The system may also determine a type of the substance, such as water, snow, sand or mud, based on electrical resistance of the substance detected by the sensors. Cameras or other imaging equipment, including LIDAR, may also be used to determine the substance height and/or composition. Accordingly, actions to protect the vehicle may be taken, such as raising or lowering the ride height of the vehicle body using an adjustable suspension of the vehicle. Other protective actions may include closing vents, seals, valves and battery isolation units, and transmitting messages to a vehicle driver and/or to emergency personnel.

First claim

What is claimed is:

1. A method comprising:
receiving signals from two or more sensors positioned on a wheel of a stopped vehicle;
determining, based on the signals, a height level of a substance in contact with the wheel;
determining, based on the signals, a type of the substance in contact with the wheel; and
determining a protective ride height for at least a portion of the vehicle, based on the height level of the substance and the type of the substance; and
causing an adjustable suspension of the vehicle to adjust a current ride height of the vehicle to the protective ride height.

2. The method of claim 1 , wherein a first sensor of the two or more sensors is positioned at a first radial distance from a center of the wheel, and a second sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the first sensor and with the second sensor, and
wherein the determining the protective ride height comprises determining, based on the type of substance in contact with the wheel being water, a raised ride height relative to a normal stopped ride height.

3. The method of claim 2 , wherein a third sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor and from the second sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the third sensor, with the second sensor and with the first sensor, and
wherein the raised ride height is a highest position obtained by the adjustable suspension.

4. The method of claim 2 , further comprising:
determining, at a first time, that the substance is in contact with the first sensor and that the second sensor is free of contact with the substance;
determining, at a second time subsequent to the first time, that the first sensor and the second sensor are in in contact with the substance;
determining an accumulation rate of the substance in contact with the wheel based on a time interval between the first time and the second time; and
in response to the accumulation rate, generating transmission of a message to a device remote from the vehicle.

5. The method of claim 1 , wherein a first sensor of the two or more sensors is positioned at a first radial distance from a center of the wheel, and a second sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the first sensor and with the second sensor, and
wherein the determining the protective ride height comprises determining, based on the type of substance in contact with the wheel being snow or sand, a lowered ride height relative to a normal stopped ride height.

6. The method of claim 5 , wherein the lowered ride height is a lowest position obtained by the adjustable suspension.

7. The method of claim 1 , wherein the two or more sensors are positioned at a rim of the wheel.

8. A system comprising:
communication circuitry configured to receive signals from two or more sensors positioned on a wheel of a stopped vehicle; and
processing circuitry configured:
to determine, based on the signals, a height level of a substance in contact with the wheel;
to determine, based on the signals, a type of the substance in contact with the wheel; and
to determine a protective ride height for at least a portion of the vehicle, based on the height level of the substance and the type of the substance; and
to cause an adjustable suspension of the vehicle to adjust a current ride height of the vehicle to the protective ride height.

9. The system of claim 8 , wherein a first sensor of the two or more sensors is positioned at a first radial distance from a center of the wheel, and a second sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the first sensor and with the second sensor, and
wherein the determining the protective ride height comprises determining, based on the type of substance in contact with the wheel being water, a raised ride height relative to a normal stopped ride height.

10. The system of claim 9 , wherein a third sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor and from the second sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the third sensor, with the second sensor and with the first sensor, and
wherein the raised ride height is a highest position obtained by the adjustable suspension.

11. The system of claim 9 , wherein the system is configured:
to determine, at a first time, that the substance is in contact with the first sensor and that the second sensor is free of contact with the substance;
to determine, at a second time subsequent to the first time, that the first sensor and the second sensor are in contact with the substance;
to determine an accumulation rate of the substance in contact with the wheel based on a time interval between the first time and the second time; and
in response to the accumulation rate, to generate transmission of a message to a device remote from the vehicle.

12. The system of claim 8 , wherein a first sensor of the two or more sensors is positioned at a first radial distance from a center of the wheel, and a second sensor of the two or more sensors is positioned at the first radial distance from the center of the wheel and spaced remote from the first sensor,
wherein the determining of the height level of the substance in contact with the wheel comprises determining that the substance is in contact with the first sensor and with the second sensor, and
wherein the determining the protective ride height comprises determining, based on the type of substance in contact with the wheel being snow or sand, a lowered ride height relative to a normal stopped ride height.

13. The system of claim 12 , wherein the lowered ride height is a lowest position obtained by the adjustable suspension.

14. The system of claim 8 , wherein the two or more sensors are positioned at a rim of the wheel.
