The electronic content in an automobile is ever increasing for last several years due to emissions, safety and performance requirements. The complete development cycle of an electronic controller needs to be compressed to introduce new vehicle models in the market ahead of time. Antilock Braking System (ABS) ECU is one such example which has become a standard feature for most of the vehicles due to safety considerations.
A project was undertaken to develop ABS ECU strategy from concept to vehicle trials with Model Based Development (MBD) technique. A methodology is established for scalable, fault tolerant, proven, and quick to implement ECU strategy development.
This paper presents the development cycle followed for a unique ABS controller. The methodology of the project with all major steps like ABS system specifications development, selection and setting up the simulation platform, ABS strategy development, testing on Model in Loop (MIL)/Hardware in Loop (HIL)/Rig in Loop (RIL) platform, ABS test results, vehicle trials etc are described. The challenges faced, solutions developed and lessons learnt are presented
