An Ultra High Bandwidth Automotive Rapid Prototype System

Abstract
For developers of automotive control, prototyping and initial tests

are a hassle. Commercial solutions are available but the price and especially

the price/performance ratio opens the field for more cost effective solutions.

Automotive rapid prototype systems seen so far are mainly processor based

systems with standard interrupt driven measurement and actuation. Control

systems based on high time resolution measurements of for example cylinder

pressure are difficult to implement using these systems, neither is it possible to

implement controller loops with an extremely high bandwidth in combination

with expensive algorithms. Measurement and actuation within the same... (More)
For developers of automotive control, prototyping and initial tests

are a hassle. Commercial solutions are available but the price and especially

the price/performance ratio opens the field for more cost effective solutions.

Automotive rapid prototype systems seen so far are mainly processor based

systems with standard interrupt driven measurement and actuation. Control

systems based on high time resolution measurements of for example cylinder

pressure are difficult to implement using these systems, neither is it possible to

implement controller loops with an extremely high bandwidth in combination

with expensive algorithms. Measurement and actuation within the same engine

cycle, In Cycle Control (ICC) are not possible. The proposed system is based on a

mixed system consisting of one standard x86 processor which is configured through

Simulink and a reconfigurable application specific integrated circuit (an FPGA)

configured either by relevant FPGA design tools or by Simulink. This layout of the

rapid prototype system enables the designer to implement either ICC with very

high bandwidth (only limited by the capacity of the injection system) or betweencycle

control with medium bandwidth. The aim of this paper is to describe one

possible configuration of such a system and to discuss the possible performance

outcome of the final system. (Less)
