Abstract: A safety control device for safely controlling a hazardous installation has a first and a second calculation unit and an output unit for driving at least one actuator. The control device acquires an input signal and determines a floating point value depending on the input signal. The first and second calculation units each determine an input interval as a function of the floating point value. The first and second calculation units each further determine a result interval as a function of the input interval by applying a first calculation algorithm to the input interval. The first calculation algorithm is based on interval arithmetic. The result intervals from the first and second calculation units are compared and an output value is determined as a function of the result intervals. An output signal is determined as a function of the output value. The output signal drives the at least one actuator.

Abstract: A sunroof apparatus comprises a drive motor which actuates a roof glass and a control section. The control section rotates the drive motor reversely when the movement of the sunroof is obstructed by a caught foreign matter. When a drive voltage to be supplied to the drive motor becomes lower than a reference voltage, the control section determines that the drive voltage is abnormal and stops supplying the drive voltage to the drive motor to inhibit the drive motor from being operated. A first reference voltage is used as the reference voltage at the time the drive motor is stopped, and a second reference voltage lower than the first reference voltage is used as the reference voltage at the time the drive motor is operated. It is therefore possible to detect a foreign matter being caught before an abnormality of the drive voltage is determined.
