Recently, the application of electrical and electronic (E/E) control system has been increased in the construction equipment. Thus, the risks caused by systemic failure and potential malfunction of the E/E control system should be considered in design process. The design methods according to the functional safety standards have been recommended to reduce these risks because they could not be removed only by the quality control. This paper described the functional safety design by using design & verification methods based on the development process of ISO 26262, ISO 13849 and ISO 15998. The support process for the functional safety was described by the standard for automobile (ISO 26262) including state-of-the-art methods. The functional safety design methods are expected to improve not only the functional safety but the quality and the reliability of the E/E control systems as well.
