A system for remotely accessing an engine control system and selectively controlling and changing an existing engine algorithm. In a preferred embodiment, the system comprises an on-board vehicle communications system which receives and sends data to a remote central fixed base site. A truck operator contacts the fleet base manager via the on-board communications system and requests, for example, that the engine idle for a specified period of time. The fleet base manager at the remote central fixed based site then transmits data from a computer over a communications channel to the vehicle\s on-board communications system. The data is sent through a remote command interface device which translates the data in language recognizable by an engine control device. Based on the data transmitted, the engine control device disables an existing idle shutdown system and permits the engine to remain idle for an amount of time specified by the truck fleet manager.

A vehicle control system for controlling engine operation in response to execution of a sequence of commands stored onboard the vehicle and modifiable from a central fixed base site which monitors one or more such vehicles at a distant location, comprising: (a) an engine control means connected to an engine of the vehicle including storage means for controlling the operation of said engine by executing a sequence of commands stored aboard the vehicle in said storage means; (b) remote vehicle operation control means located at the fixed base site for generating and transmitting from said fixed base site to the vehicle an instruction to modify one or more of the stored sequence of commands; (c) an on-board communications module for receiving said instruction from the fixed base site and modifying the sequence of commands stored in said storage means; and wherein engine operation occurring at any future time based on the execution of said stored sequence of commands may be remotely modified, in advance, by the generation and transmission of said instructions to modify said sequence of commands.
