1. A cruise control system for a vehicle, comprising:
- an output device operative to transmit information to a vehicle operator;
one or more control inputs;
one or more signal generators associated with the one or more control inputs and capable of generating signals indicative of the actuation of the one or more control inputs; and
a controller configured to;
1) receive signals generated by the one or more signal generators;
2) stores said signals generated by the one or more signal generators;
3) determine cruise control system inoperability or cruise control system operability based on said stored signals;
4) in response to a determination of cruise control system inoperability, generate cruise control inoperability information for output by the output device for notifying the vehicle operator of cruise control system inoperability, the cruise control system inoperability caused by at least one signal generator of the one or more signal generators; and
5) generate signals for output by the output device as instructions for the vehicle operator to activate the at least one control input associated with cruise control system inoperability in an attempt to restore cruise control system operability.

Abstract
Cruise control systems and methods suitable for use in vehicles, such as Class 8 trucks, are provided. For example, cruise control systems are disclosed that include verification and/or notification features for verifying the operational condition of the cruise control system, and if non-operational, notifies the vehicle operator of system inoperability and/or instructs the operator to activate a specified control input, e.g., press and release the clutch pedal, the service brake pedal, the parking brake, etc., so that cruise control functionality may be enabled.

11. A vehicle cruise control system capable of controlling the operation of a vehicle engine, comprising:
-
an output device operative to transmit information to a vehicle operator; one or more control inputs; a cruise control monitoring system for monitoring the activation of the one or more control inputs, the cruise control monitoring system including one or more signal generators associated with the one or more control inputs and capable of generating signals indicative of the actuation of the one or more control inputs; and a control unit configured and arranged to enable control of the vehicle engine and disable control of the vehicle engine, wherein prior to vehicle engine control enablement, the control unit;
1) receives signals generated by the cruise control monitoring system;
2) stores said signals generated by the cruise control monitoring system;
3) determines if the cruise control system is operable by conducting functionality checks for each of the one or more signal generators based on said stored signals;
4) in response to a determination of cruise control system inoperability, notifies the vehicle operator of non-enablement of vehicle engine control, the cruise control system inoperability caused by one or more failed functionality checks of the one or more signal generators;
5) instructs the vehicle operator via the output device to activate the one or more control inputs associated with the failed functionality checks, and
6) verifies the operability of the cruise control monitoring system upon activation by the vehicle operator of the one or more control inputs associated with the failed functionality checks.
