EU OBD legislation requirements will bring new challenges for motorcycle engine control from 2020 and 2024 respectively. This paper gives a perspective on the Bosch solutions for On Board Monitoring functions to implement the legislation requirements. Specifically the approach and validation results for the monitor for Secondary Air Injection (SAI) will be highlighted. OBD is well established e.g. for passenger car systems in worldwide markets with Bosch solutions covering different system configurations and legislation requirements. While a large portion of the required OBD monitors for motorcycles can be carried over from passenger car solutions with modifications and enhancements where needed, some specific monitors had to be developed from scratch. These new monitors are required for subsystems and components which do not exist in the passenger car environment, e.g. a controlled valve between the intake manifold and engine outlet of the motorcycle to implement secondary air injection. Special focus of this presentation is on the OBD monitoring of the secondary air injection control valve, where robustness is a challenge given the boundary conditions of only binary lambda sensors available in the systems. Challenges are detection of the actual functioning of the secondary air valve with the binary downstream lambda sensor under real world operating conditions and completion of the diagnostic in the WMTC and on the road. A proof of the chosen conceptual approach is given by the implementation into series software and by validation test results on a 1-cylinder motorcycle. Measurements show, that a malfunction will be detected both in the WMTC and during normal driving.
