Rapid development of control software is one of the most important aspects in the vehicle industry. Especially where electric vehicles are concerned, new controllers have to be developed and integrated into existing software architectures. One example is the brake system, which in contrast to traditional brakes involves electrohydraulic brakes and thus needs special controller software. Recuperation also has to be taken into account, and the brake must provide a proper brake feeling for the driver.
This paper presents a sophisticated recuperative brake system modeled in MATLAB/Simulink and describes how it is integrated into an AUTOSAR architecture. This architecture is then enhanced with an ECU configuration including basic software modules.
A dedicated continuous tool chain is used to perform these steps. This tool chain must ensure that simulation-based testing, using a complex environment model with a vehicle multi-body system, is possible in every development step. The main benefit of using a continuous tool chain is that the controllers can be tested on an AUTOSAR architecture level in early stages of the development process.
