Abstract: A control system keeps a controlled device operating even when a microcomputer of the system overruns during operation of the controlled device.

Abstract: A head lamp (3) is turned off when a first set time (T1) has lapsed in a state that a circumferential illumination intensity (B) is equal to or higher than a first level (B1), or when the vehicle has run a first set distance (L1) in a state that the circumferential illumination intensity (B) is equal to or higher than a second level (B2) lower than the first level (B1). Accordingly, even if the vehicle is stopped immediately after a moving to a bright place from a dark place, or even if the peripheral environment has become bright during a stop in the dark place, the head lamp (3) can be securely turned off.

Abstract: In apparatus and method for cruise control for an automotive vehicle, a controller is provided for running a self-diagnosis upon a receipt of the power supply via the first switch, for determining whether the apparatus operates normally or abnormally as a result of the run of the self-diagnosis, and for starting an acceptance of an input of the signal from the second switch when determining that the apparatus operates normally as the result of the self-diagnosis, and for issuing a warning signal when determining that the apparatus operates abnormally when the input of the signal from the second switch occurs at a time of the start of the acceptance of the input of the signal from the second switch and the input of the signal from the second switch occurs after a predetermined time has passed from the time when the acceptance of the input of the signal from the second switch occurs.

Abstract: Attention is given to that, when a catch-in state occurs while a vehicle window glass is moved upward, a current flowing in a motor serving as a drive means for moving the vehicle window glass increases. In an apparatus for comparing a predetermined current threshold value with a current detected by a motor current monitor unit to recognize a catch-in state, the predetermined current value is made variable, and the catch-in state can be correctly recognized without an erroneous operation even when the external environment changes, or when the window glass is moved upward for the first time. In particular, a current value obtained at the start of the motor and changed by a circumference temperature of the motor is set as a current threshold value, and the current threshold value is set each time the motor is started. A current value in an upward moving operation is estimated each time the window glass is moved downward to set the current value as a current threshold value.
