PSI5 is an open standard for bidirectional digital sensor data communication in vehicles. Compared to analog options, this solution has advantages particularly with respect to robustness, reliability, and costs. The standard is applied, among other fields of use, for connecting distributed sensors for the control of airbag systems, chassis, and powertrain.
