The ASM Box allows efficient verification of PVE and OBD calibration via electrical modulation of actuator and sensor signals, especially for U.S. homologation with government mode in addition to the common user mode. Because no faulty hardware is required for failure generation it achieves a cost savings of at least 20 percent in typical use cases. Using the ASM Box for automated drifting of sensor signals for robustness testing improves the quality as well as the efficiency.
FEV’s ASM Box is based on a model-based automotive RCP system. With predefined Simulink® models, efficient and fast modulation of any engine component can be realized. The standard models can be easily customized to satisfy individual modulation needs. In the case of calibration tasks, it is possible to use a calibration tool with XCP support to control the model behavior and simultaneously handle ECU labels and signals. In the case of homologation, the ASM Box offers a user friendly GUI with the possibility of controlling the system via WiFi and LAN.
