Remote control of engine operation in a motor vehicle
First Claim
1. A control input selection system for controlling an engine in a motor vehicle through the selective use of two sets of control inputs to an engine control system, one set comprising occupant compartment controls inside an occupant compartment and the other set comprising remote controls outside the occupant compartment, the selection system comprising:
- a selection input to the engine control system for selecting one of the two sets; and
a processor in the engine control system for processing the selection from the selection input and enabling the engine control system, once the engine has been started and is running, to control certain functions related to running of the engine from the set selected by the selection input to the exclusion of the other set.

Abstract
A set of remote switches (14, 16) located outside the cab of a truck enables service personnel to crank, accelerate, decelerate, and shut off the truck'"'"'s engine without having to enter the cab. The set of switches are interlocked with controls (12, 13) inside the occupant compartment, including the ignition switch (12) that is used to crank the engine from inside the cab, via an engine control system (11) that uses the state of a switch that senses locking/unlocking of the cab on the chassis engine control system (11) to select either the remote switches or the occupant compartment controls to the exclusion of the other for controlling engine running once the engine has been cranked and started.
