Rumble strip responsive system: vehicle control on rumble strip
First Claim
1. A device adapted to automatically control the effective output of a vehicle control system/component in response to tire contact with a rumble strip, comprising:
- a processor adapted to receive at least a first signal indicative of contact of a first vehicle tire with a rumble strip, wherein the processor includes logic to;
determine that at least one vehicle tire is in contact with a rumble strip based at least on the first signal; and
only if the processor has received the first signal and has determined that the at least one vehicle tire is in contact with the rumble strip, issue a command to control the effective output of at least one of a vehicle control component or a vehicle control system to take into consideration influence of a reduced coefficient of friction due to tire contact with the rumble strip.

Abstract
A device adapted to automatically control the effective output of a vehicle control system/component that, for example, automatically applies braking and/or steering control, in response to tire contact with a rumble strip. The device includes a processor configured to receive a first signal indicative of contact of a vehicle tire with a rumble strip. The processor also includes logic to determine that at least one vehicle tire is in contact with a rumble strip based at least on the first signal. If the processor has received the first signal and has determined that the at least one vehicle tire is in contact with the rumble strip, the processor then issues a command to control the effective output of at least one of a vehicle control component or a vehicle control system. For example, an automatically applied braking force may be reduced to ½ its normal applied force.

27. A device adapted to automatically control the effective output of a vehicle control system/component in response to tire contact with a rumble strip, comprising:
a processor adapted to receive at least a first signal indicative of at least one of (i) contact of a first vehicle tire with a rumble strip and (ii) absence of contact of the first vehicle tire with a rumble strip, wherein the processor includes logic to; determine that no vehicle tire is in contact with a rumble strip based at least on one of (i) the first signal and (ii) an absence of the first signal; and only if the processor has determined that no vehicle tire is in contact with the rumble strip, issue a command to enable at least one of a vehicle control component or a vehicle control system. - View Dependent Claims (28, 29, 30, 31, 32, 33)

34. A program product for automatically controlling the effective output of a vehicle control system/component in response to tire contact with a rumble strip comprising machine-readable program code for causing, when executed, a machine to perform the following method:
-
determine that at least one vehicle tire is in contact with a rumble strip based at least on a first signal indicative of contact between a vehicle tire and a rumble strip; and only if a processor has received the first signal and has determined that the at least one vehicle tire is in contact with the rumble strip, issue a command to control the effective output of at least one of a vehicle control component or a vehicle control system.
