IAV Primero 2.0: Fault simulation for next-generation lambda sensors

On-board diagnostics (OBD) of the lambda sensor must be able to detect ageing effects and defects in the lambda sensor in good time. This must be done before the sensor is no longer able to provide the necessary signals for emission-related functions in the vehicle (e.g. mixture control, catalytic converter diagnostics). With IAV Primero, these diagnostics can be designed, tested and demonstrated to the approval authority.

New Version now available!

New version now available! We have redeveloped the hardware of our Primero in response to feedback from our customers. Generation 2.0 of the IAV Primero incorporates our experience of the last 20 years. You can order the IAV Primero 2.0 from 2024 and benefit from the new features.

Support for a wide range of current and future lambda sensors (via software update)
Efficient use of limited test vehicles
Simple test execution through predefinable test configuration
Automatic and seamless test documentation

Cost-Effective Testing

With IAV Primero, you save money on the costly replacement of sensors and can better utilize your resources by using the same vehicle for various types of tests.

User-Friendly Device Configuration

Thanks to the predefined configuration files created during test planning, device configuration is easy and quick to set up, even for untrained personnel.

Accurate and Automated Documentation

IAV Primero automatically documents the entire testing process, including key signals, settings, and serial numbers, thereby reducing human errors and streamlining the documentation process.

Compatibility with All Types of Lambda Sensors

Our tool has unmatched compatibility with leading lambda sensor and control unit manufacturers, ensuring that you can use IAV Primero in the future without any compatibility issues.

IAV Primero 2.0 enables developers to distort the complex signal processing of lambda sensor signals in a simple way. This makes it possible to provide the OBD algorithms in the engine management system with a lambda sensor signal that can be modified by means of freely configurable error patterns. The lambda sensor signal path is distorted at vehicle level without the need to intervene in the engine control unit functions. This means that the effectiveness of the on-board diagnostics can be verified in its unchanged standard state and demonstrated as part of the vehicle approval process. IAV Primero 2.0 is therefore a tool for the entire development process – from function development, application and validation on test drives through to demonstration to the authorities as part of the approval process (COP).

IAV Primero 2.0 can be easily integrated into the signal path between the lambda sensor and engine control unit in any vehicle environment via the universal wiring harness. One linear and one binary sensor can be controlled simultaneously by IAV Primero 2.0. Configuration and control are carried out conveniently via the user interface from a laptop connected to IAV Primero 2.0 via USB. The existing CAN interface enables seamless integration of the data generated by IAV Primero 2.0 into the existing application environment (e.g. ETAS INCA). As a result, your entire test sequence is documented automatically, completely and seamlessly.

Accessories

To ensure that IAV Primero 2.0 can be easily integrated into any vehicle project, a USB connection cable and a universal adapter for connection to the power supply, the engine control unit and lambda sensors are also included in the scope of delivery for IAV Primero 2.0. IAV Primero 2.0 is always supplied in a transport case.

Intuitive user interface

All the necessary test parameters can be set using a clear and easy-to-understand user interface. A primero configuration created in test planning can be saved and easily imported into Primero for test execution. This ensures that all tests are carried out with the correct settings and independently of the personnel carrying them out.

Probe compatibility

IAV Primero 2.0 supports current probe models and control units. Its compatibility with the new OSIC driver from Bosch is unique. Thanks to the future-proof hardware design of IAV Primero 2.0, future probe models can also be supported via a software update.

Some obsolete probe models are no longer supported by Primero 2.0. Please ask us for a Primero of the latest generation (iav-primero@iav.de). For detailed information on the supported probes/driver combinations, please refer to the following compatibility matrix.
