Remote control of engine idling time
First Claim
1. 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.

Abstract
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.

15. A vehicle control system remotely operated to access an engine control device and selectively enable or disable an idle shutdown device which automatically shuts the engine of a vehicle down after detecting a predetermined period of continuous idling time, said system comprising:
-
a communicative means for transmitting information between a remote fixed base site and a vehicle via an on-board vehicle communications system; and a processing means located in said engine control device for analyzing and storing said information transmitted between said remote fixed base site and said vehicle, and for modifying and implementing a preexisting sequence of commands stored in said engine control device based on said information, wherein said engine control device uses said information transmitted between said remote fixed base site and said vehicle to disable said idle shutdown device and allow the engine of said vehicle to remain in an idle state for a determined period of time. - View Dependent Claims (16)

17. A vehicle control system for automatically stopping the engine of a vehicle after detecting a predetermined period of continuous idling time, said system comprising:
-
idle shutdown means or monitoring engine idling and automatically stopping the engine of a vehicle after detecting a predetermined period of continuous idling time; and idle shutdown bypass means connected to the idle shutdown means or receiving a remote user instruction to bypass said idle shutdown means and, in response to the instruction, allow the engine to idle for the duration of an idle bypass period set by the user through modification of an existing sequence of commands stored in said idle shutdown bypass means, and after the expiration of said idle bypass period, automatically reenable the operation of said idle shutdown means to limit idling time of the engine. - View Dependent Claims (18, 19, 20, 21)

22. A method of varying the operation of an engine which is controlled by an electronic monitoring and control system using one or more programmed control algorithms, in response to commands received from a central remote fixed base site which monitors one or more vehicles at a distant location, comprising the steps of:
-
receiving data signals transmitted from said central remote fixed base site to a vehicle at a distant location; interpreting said data signal to identify an instruction transmitted by a remote user; identifying an engine algorithm to be modified based on said instruction; and varying said identified engine algorithm of said vehicle in accordance with said instruction transmitted by said remote user. - View Dependent Claims (23, 24, 25)
