Abstract

A hot-start suspension tune system and method is disclosed. The method initiates a starting suspension tune for a vehicle. The starting suspension tune is maintained until a predefined threshold is reached. After the predefined threshold is reached, the starting suspension setting is automatically modified to a performance suspension setting.

Claims (43)

1. A hot-start method comprising:

initiating a starting suspension setting for a vehicle;

maintaining said starting suspension setting for said vehicle until a predefined threshold is reached; and

automatically modifying said starting suspension setting to a performance suspension setting after reaching said predefined threshold.

2. The method of claim 1 , wherein said starting suspension setting is a firmer setting than said performance suspension setting.

3. The method of claim 1 , further comprising:

utilizing an electronic valve of a shock assembly to automatically modify at least one suspension characteristic of said shock assembly.

4. The method of claim 1 , wherein said predefined threshold is a predefined time period, and said method further comprises:

initiating said predefined time period after a user input feature is manipulated.

5. The method of claim 1 , wherein said predefined threshold is a predefined time period, and said method further comprises:

initiating said predefined time period after a predefined acceleration value is detected by an accelerometer.

6. The method of claim 1 , wherein said predefined threshold is a predefined time period, and said method further comprises:

initiating said predefined time period after a predefined force is detected by a pedal sensor.

7. The method of claim 1 , wherein said predefined threshold is a predefined time period, and said method further comprises:

initiating said predefined time period after a location relative to a predefined location is determined, wherein said location relative to said predefined location is selected from a group consisting of: moving into said predefined location, moving out of said predefined location, and moving through said predefined location.

8. The method of claim 1 , wherein said predefined threshold is a speed.

9. The method of claim 1 , wherein said predefined threshold is a distance.

10. A non-transitory computer-readable medium for storing instructions, said instructions comprising:

one or more instructions which, when executed by one or more processors, cause one or more processors to:

initiate a starting suspension tune for a shock assembly;

maintain said starting suspension tune for said shock assembly for a predefined time period; and

automatically modify said starting suspension tune to a performance suspension tune after an expiration of said predefined time period.

11. The non-transitory computer-readable medium of claim 10 , wherein said starting suspension tune is firmer than said performance suspension tune.

12. The non-transitory computer-readable medium of claim 10 , wherein said one or more processors are further configured to:

utilize an electronic valve of said shock assembly to automatically modify at least one suspension setting of said shock assembly.

13. The non-transitory computer-readable medium of claim 10 , wherein said one or more processors are further configured to:

initiate said predefined time period after a user input feature is manipulated.

14. The non-transitory computer-readable medium of claim 10 , wherein said one or more processors are further configured to:

initiate said predefined time period after a predefined acceleration value is detected by an accelerometer.

15. The non-transitory computer-readable medium of claim 10 , wherein said one or more processors are further configured to:

initiate said predefined time period after a predefined force is detected by a pedal sensor.

16. The non-transitory computer-readable medium of claim 10 , wherein said one or more processors are further configured to:

initiate said predefined time period after a location relative to a predefined location is determined, wherein said location relative to said predefined location is selected from a group consisting of: moving into said predefined location, moving out of said predefined location, and moving through said predefined location.

17. A hot-start system comprising:

at least one shock assembly comprising an electronic valve, said at least one shock assembly being part of a vehicle suspension;

a starting mode initiator configured to set said at least one shock assembly to a starting tune;

an input receiver configured to receive an input and initiate a timer; and

a controller in communication with said electronic valve of said at least one shock assembly, said controller to:

receive an indication that said timer has tolled; and

communicate an adjustment command to said electronic valve to change said at least one shock assembly to a different mode.

18. The hot-start system of claim 17 , wherein said input receiver is a user manipulatable feature and said timer is initiated after said input receiver is manipulated.

19. The hot-start system of claim 17 , wherein said input receiver is a sensor and said timer is initiated after a predefined threshold value is detected by said sensor.

20. The hot-start system of claim 17 , wherein said input receiver is a location sensor and said timer is initiated after a location relative to a predefined location is determined, wherein said location relative to said predefined location is selected from a group consisting of: moving into said predefined location, moving out of said predefined location, and moving through said predefined location.
