This board controls, simulates, and manipulates all the relevant special signals in hybrid vehicles and measures the activation time of the safeguards. It makes it possible to flexibly vary the resistance of the pilot-interlock current and simulate errors selectively. The pilot-interlock current can also be measured. Test engineers can greatly vary the crash signal parameters and thereby verify the threshold between the triggering of the security function and the activation of security devices, such as the disconnection of the high voltage lines.
The board measures the time delay between crash signal activation and control device reaction down to the microsecond. In addition, the board offers a standard on-board diagnosis (OBD) error simulation for all signals as well as the simulation of battery balancing chips that are controlled over the I2C-Bus as a special feature.
