Legal emission regulations require effective technology solutions. For fuel to burn optimally and with low emissions in the combustion engine, the oxygen content of the fuel-air mixture must be continuously adjusted to the engine operating point. The lambda sensor is a central component in this emission-relevant control system, the function of which must be monitored over the entire service life of the vehicle using on-board diagnostics (OBD).
“With the new generation of the IAV Primero, we are taking a significant step towards optimized fault detection and correction for lambda sensors”, explains Kevin Schössow, Sales Manager at IAV. “Our customers benefit from a simple yet extremely effective method of simulating aging effects and defects in the lambda sensor and adapting on-board diagnostics early on in the development process, thereby avoiding potential problems with emission-related functions in the vehicle.”
IAV’s error simulation tool enables the complex signal processing of the lambda sensor to be distorted in a simple way. This allows a lambda sensor signal to be fed to the OBD algorithms in the engine control unit, which is modified by freely configurable fault patterns. The advantage: the effectiveness of the OBD diagnostics can be verified in their unchanged series condition and demonstrated as part of the vehicle registration process using IAV Primero.
Numerous new product features
The new generation of the IAV Primero offers customers additional features, such as greater robustness against electromagnetic interference (EMI), finer fault pattern control thanks to more precise tuning of the heater series resistors, significantly simplified calibration of the sensor readiness detection and the option of carrying out an empty pipe simulation on the vehicle in future.
Future-proof
The hardware of the Primero 2.0 has been developed from scratch to ensure support for current and future lambda sensors and drives. The IAV Primero 2.0 is therefore currently the only fault simulation tool on the market that supports the new Bosch OSIC sensors. Via software updates, we will be able to provide support for further lambda sensors and drivers in the future.
The IAV Primero can be easily integrated into the signal path between the lambda sensor and the engine control unit in any vehicle environment via the universal wiring harness. The system enables the simultaneous control of a linear and a binary sensor and is conveniently controlled via the user interface of a laptop. The test sequence can also be automated so that Primero can also be used in endurance tests. The data generated is seamlessly integrated into the existing application environment via the existing CAN interface, for example with ETAS INCA.
Of course, the Primero 2.0 also supports all previously relevant probe models and ECUs. This enables smooth integration into existing vehicle projects and significantly reduces the implementation effort.
