Abstract

A system that identifies road conditions associated with a road surface is provided. The system includes a first sensor recording a first motion amount related to a head of a rider and at least a second sensor recording at least a second motion amount of a portion of a vehicle. The system also includes a comparison manager determining a severity level based on a comparison between the first motion amount and the second motion amount. Also included is a notification manager providing recommendations to the rider based on the severity level. Additionally, an implementation manager may dynamically implement one or more actions based on the severity level.

Claims

1. A system that identifies road conditions associated with a road surface, comprising:

a first sensor recording a first motion amount of a head of a rider;

a second sensor recording a second motion amount of a portion of a vehicle;

a comparison manager determining a severity level based on a comparison between the first motion amount and the second motion amount; and

a notification manager providing at least one recommendation to the rider based on the severity level.

2. The system of claim 1, further comprising a third sensor recording a third motion amount of another portion of the vehicle different than the portion of the vehicle.

3. The system of claim 2, wherein the second sensor is operatively attached to the vehicle above a vehicle suspension and the third sensor is operatively attached to the vehicle below the vehicle suspension.

4. The system of claim 2, wherein the second sensor is operatively attached to a body of the vehicle and the third sensor is operatively attached to a wheel of the vehicle.

5. The system of claim 1, wherein the first sensor is operatively attached to a helmet of the rider.

6. The system of claim 1, wherein the comparison manager assigns a smoothness score to a portion of the road surface, wherein the smoothness score is determined based at least in part on the severity level.

7. The system of claim 1, wherein the comparison manager compares the first motion amount and the second motion amount to a natural frequency of the rider and the vehicle.

8. The system of claim 1, further comprising a locator determining a location of the rider at about the same time as a trigger event occurs.

9. The system of claim 8, wherein the trigger event is determined based on a determination that a difference between the first motion amount and the second motion amount is above a threshold level.

10. The system of claim 8, wherein the trigger event is determined based on an input received from the rider.

11. The system of claim 1, wherein the first sensor comprises a G sensor capable of determining acceleration.

12. A method for identifying road conditions associated with a road surface, comprising:

obtaining, by a system comprising a processor, a set of measurements, wherein respective measurements of the set of measurements are determined at different levels of a vehicle suspension;

comparing, by the system, respective measurements of the set of measurements;

determining, by the system, at least one action based on a determination that a difference between at least two measurements of the respective measurements is above a threshold amount; and

outputting, by the system, a recommendation that includes an implementation of the at least one action.

13. The method of claim 12, wherein the obtaining the set of measurements comprises:

receiving, by the system from a first sensor located a first portion of the vehicle body, a first measurement of the set of measurements;

receiving, by the system from a second sensor located on a second portion of the vehicle body, a second measurement of the set of measurements; and

receiving, by the system from a third sensor located on a rider of the vehicle, a third measurement of the set of measurements, wherein the first sensor, the second sensor, and the third sensor are inertial measurement units.

14. The method of claim 13, wherein the first portion of the vehicle body is below a suspension level and the second portion of the vehicle body is located above the suspension level.

15. The method of claim 12, further comprising determining, by the system, a location of the vehicle at about the same time as a trigger event occurs.

16. The method of claim 12, wherein the comparing comprises:

determining a difference between a first measurement taken below a suspension level of the vehicle and a second measurement taken above the suspension level; and

triggering an action based on the second measurement being more than the first measurement.

17. A system for implementing an action based on road conditions associated with a road surface, comprising:

a first sensor recording a first motion amount at a first portion of a vehicle located below a suspension level;

a second sensor recording a second motion amount at a second portion of a vehicle located above a suspension level;

a third sensor recording a third motion amount at a helmet;

a comparison manager determining a severity level based on a comparison between the first motion amount, the second motion amount, and the third motion amount; and

a notification manager providing at least one recommendation to the rider based on a determination that the severity level is above a threshold amount.

20. The system of claim 17, wherein at least one of the first sensor, the second sensor, and the third sensor comprises a G sensor capable of determining acceleration.
