A cruise control interlock system detects a current set of conditions for a vehicle, compares the current conditions with cruise control interlock conditions (e.g., an adjustable threshold state of a windshield wiper system), and executes a process to deactivate the cruise control system. The process to deactivate functionality of the cruise control system may include presenting a notification to the operator to alert the operator to an upcoming automatic deactivation or to encourage the operator to deactivate cruise control. The process also may include a vehicle de-rate process (e.g., reducing vehicle speed) to induce the operator to deactivate cruise control. Deactivation of cruise control may be postponed in some situations, such as when the vehicle is ascending an uphill grade or where doing so may deactivate an active downhill speed control function.

Approaches to control engine overspeed are provided. Engine overspeed is controlled by one or more mechanisms that operate the intake and/or exhaust valves of the engine to interrupt the combustion cycle. In use, the 'combustion interrupter' mechanism(s) actuate the intake and/or exhaust valves according to, for example, one or more control strategies in order to interrupt the combustion cycle and/or cause the engine to expend energy to move the pistons through a complete cycle in an aim to retard engine speed. The engine's cam(s) can include one or more sets of variable valve timing lobes that operate the intake and/or exhaust valves of the engine in order to, for example, interrupt the combustion cycle. The combustion interrupter mechanism can additionally or alternatively include one or more computer controlled actuators that operate the intake and/or exhaust valves in order, for example, to interrupt the combustion cycle.

Engine overspeed shutdown systems and methods

A system for delivering air to vehicle engines generally includes at least one air cleaner configurable to receive either conditioned air or unconditioned air and a conduit assembly coupled to the air cleaner for delivering cleaned air from the air cleaner to the vehicle engine.
