Abstract: The present invention relates to a vehicular control device including a plurality of ECUs connected to each other through an in-vehicle network. The vehicular control device includes a first control device that controls an electrical component and a second control device connected to the first control device through an in-vehicle network. In a case where an operation switch of the electrical component in the first control device is fixed in an on-state and an ignition key is off, data transmission from the first control device to the second control device is stopped, or the first control device is set to a reception-only mode, and thus the second control device is prevented from operating due to a wake-up function.

Abstract: A vehicle traveling control apparatus comprises abnormality monitoring means for determining whether or not a driver of a vehicle is in an abnormal state where the driver loses an ability to drive the vehicle, and decelerating means for decelerating the vehicle to automatically stop the vehicle after a conclusive abnormality determination time point which is a time point when the abnormality monitoring means finalizes the determination that the driver is in the abnormal state. The decelerating means is configured to prohibit the deceleration of the vehicle when the vehicle is in the deceleration prohibition situation after the conclusive abnormality determination time point.

Abstract: A system for two-stage determination of a brakefail of an aircraft brake system includes an aircraft brake. The aircraft brake is configured to receive a current command value, convert the current command value to a braking pressure and output a detected pressure value corresponding to the braking pressure. The system also includes a brake control unit (BCU) configured to determine a pressure command value, convert the pressure command value to the current command value and to determine whether a brakefail event has occurred based on the pressure command value, the current command value and the detected pressure value.
