The driver support system (DSS) computer is an important part of systems such as adaptive cruise control (ACC), pre-collision system (PCS), and lane-keeping assist (LKA). The DSS computer receives information from peripheral sensors such as the forward radar, forward camera, and driver-monitoring camera, and transmits requests to controllers such as the engine, brakes, steering computer, and combination meter. DSS such as those listed above use the peripheral sensors in common and are also activated simultaneously, which makes it necessary to consider coordination among the systems. For example, if a part becomes inoperable, each system that uses the part reverts to a default condition and the condition of each system is shown onthe combination meter. In such a case, the combination meter must not flash or show other such undesirable conditions. Therefore the behavior of these systems must be fully taken into consideration and guidelines for mediation constructed in terms of ergonomics. As a result, three aspects of design for mediation must be reviewed: diagnostic design, control design, and human-machine interface (HMI) design. These are all important for effective coordination among these systems.
