System and method for controlling vehicle cruise speed
First Claim
1. A system for controlling cruise speed of a vehicle, said system comprising:
- vehicle-based means for automatically controlling a throttle of the vehicle to maintain a desired cruise speed of the vehicle; and
tire-based means for monitoring an operating condition of a tire of the vehicle, said means for monitoring providing a signal indicative of a sensed operating condition of the tire to said means for automatically controlling, said means for automatically controlling determining an abnormal condition of the tire when the sensed operating condition reaches a predetermined level, said means for automatically controlling limiting the vehicle cruise speed to a predetermined maximum cruise speed when the tire is in said abnormal condition.

Abstract
A system (10) includes a vehicle-based controller (30) for automatically controlling a throttle (32) of a vehicle (14) to maintain a desired cruise speed of the vehicle. The system also includes a tire-based unit (20) for monitoring an operating condition of a vehicle tire (12) of the vehicle (14). The tire-based unit (20) provides a signal (22) indicative of a sensed operating condition of the vehicle tire (12) to the controller (30). The controller (30) determines an abnormal condition of the vehicle tire (12) when the sensed operating condition reaches a predetermined level. The controller (30) limits the vehicle cruise speed to a predetermined maximum cruise speed when the vehicle tire (12) is in the abnormal condition.

10. A system for controlling the cruise speed of a vehicle equipped with run-flat vehicle tires, said system comprising:
-
means for automatically controlling a throttle of a vehicle to maintain a desired cruise speed of the vehicle; and
means for sensing a loss if inflation pressure in any of the run-flat vehicle tires, said means for sensing being operatively connected to said means for automatically controlling to provide a signal indicative of a loss of inflation pressure in any of the run-flat vehicle tires to said means for automatically controlling, said means for automatically controlling limiting the vehicle cruise speed to a predetermined maximum cruise speed upon a loss of inflation pressure in any of the run-flat vehicle tires.

11. A method for controlling cruise speed of a vehicle, said method comprising the steps of:
-
maintaining the cruise speed of the vehicle at a desired cruise speed using a cruise control system;
monitoring an operating condition of a tire of the vehicle;
detecting an abnormal condition of the tire when the monitored operating condition reaches a predetermined level; and
limiting the cruise speed to a predetermined maximum cruise speed when the abnormal condition is detected.

12. A system for controlling cruise speed of a vehicle, the system comprising:
-
a cruise control device that automatically controls an engine throttle of the vehicle to maintain a desired cruise speed of the vehicle; and
a tire condition monitoring device associated with a tire of the vehicle and operable for sensing an operating condition of the tire, the tire condition monitoring device providing a tire condition signal indicative of a sensed tire condition, the cruise control device receiving the tire condition signal from the tire condition monitoring device and controlling the cruise speed in response to the tire condition.
