Bypass Rapid Prototyping without ECU Code Changes

Embedded Software rapid prototyping methods have been used in control algorithm development for over 10 years [1]. Bypass rapid prototyping can be described as a method of replacing a calculation or feature that is implemented in base ECU software with a modified calculation or feature that runs in either an external ECU (Electronic Control Unit) or a new location on the base ECU. Until now, a necessary condition to use bypass rapid prototyping system was to write “hooks” into the base ECU software [2]. This requires software source code modifications. This paper describes a patent pending method to enable bypass rapid prototyping technology to be used with base ECU software without any source code modifications. This new method of providing bypass rapid prototyping with production ECU software is called the ATI “No-Hooks” technology.
