Onboard electronics
SKI control and indication system
Block BKI (control and indication unit) is installed in the cab of the vehicle. Control units BKG (hydraulics), BKD (engine), BKU (universal), BKS (speedometer) are installed on the vehicle frame. The signals from the parameters control sensors are fed to the blocks BKI, BKG, BKD, BKU, BKS. In BKG, BKD, BKU, BKS blocks, these signals are analyzed and their state is transmitted to the BKI block via the SAEJ1939 interface. The BKI performs continuous diagnostics of the vehicle parameters, displaying these parameters on the screen and storing the fault block in the memory. In the BKI, with the help of signal banners, important signals and emergency operating conditions are displayed, regardless of the serviceability of the BKI, BKG, BKD, BKS, BKU blocks.
