Embodiment Construction

[0036] The truck 1 is provided with an on-board electronic control device 2 including a main electronic control unit or ECU 21 and three ECUs 22-24 which control the internal combustion engine, automatic transmission and exhaust gas treatment equipment of the truck 1, respectively. The device 2 also includes a communication module 25 connected to the ECUs 21 to 2 and adapted to exchange data with the personal computer 3 . For example, the module 25 can send a radio signal S to the computer 3 1 , and receives another radio signal S from the computer 2 . Communication between the module 25 and the computer 3 can also take place via wires plugged into the module 25 when the truck 1 arrives at the maintenance facility comprising the computer 3 . The communication between the device 2 and the computer 3 can also take place via a USB memory stick which can be loaded with data to be transferred from the device 2 to the computer 3 and vice versa.

[0037] The computer 3 includes a ...

Abstract

This system is used for adjusting the control parameters of an onboard electronic control device (2) of an automotive vehicle (1) in view of a journey or type of journey. This system includes computation means (4) adapted to generate a set of control parameters to be used by the electronic control device (2) and input means (3) adapted to allow a user to provide the computation means (4) with data relating to the journey or type of journey and to at least one constraint to be considered as having priority during the journey or type of journey. In the method of the invention, one collects data with respect to the vehicle, to the journey or type of journey and to the constraint to be considered as having priority. These data are provided to the computation means (4) which generate a set of control parameters for the control device (2).

Description

technical field [0001] The present invention relates to a system and method for adjusting control parameters of an electronic control device onboard an automobile vehicle according to a trip or a trip type. Background technique [0002] On-board electronic control units are used in automotive vehicles, especially in vans, to control equipment or subsystems such as the internal combustion engine, transmission or aftertreatment units for cleaning the exhaust. The parameters used by such in-vehicle electronic control devices are usually set by means of average values ​​at the vehicle manufacturer's factory. Such averages are not optimized according to the trip or type of trip the vehicle is to make. From US 6665606 it is known to send data from a server to an on-board electronic control unit in order to bring a particular engine into agreement with statistical average parameters. It is also known from US 6487717 that it is possible to optimize the engine of a truck according ...
