Abstract: A relay device includes a relay connected between a first communication network and a second communication network. The second communication network uses a communication protocol different from the first communication network. A first frame is transmitted in the first communication network, and has a first payload including control information, a first data ID for identifying the control information, and a data length code indicating a data length of the first payload. A second frame is transmitted in the second communication network, and has the first frame, a second data ID indicating that the first frame is included, and unique data stored in a predetermined storage area at a position behind the first frame. The relay recognizes the first frame without performing a frame recognition process on the data in the predetermined storage area when recognizing the first frame in the second frame on a basis of the data length code.

Abstract: A CGW (7) connected to a first communication network (1) and a fifth communication network (5). The second communication network uses a communication protocol different from a communication protocol of the first communication network (1). The CGW (7) receives, from the first communication network (1), CAN frames each including a data field storing control information (CD) to be transmitted from the first communication network (1) to a second communication network (5), a CAN ID for identifying the control information (CD), and an error detection code (EC) stored in the data field and calculated on the basis of the control information (CD) and the CAN ID. The CGW (7) generates an FD frame including a data field storing the CAN frames and a CAN FD ID indicating that the CAN frames are stored in the data field, and transmits the generated FD frame to the fifth communication network (5).

Abstract: In a vehicle driving support apparatus, if a brake pedal operation by a driver is detected during a braking control, a cruise control unit determines that it is highly likely that the driver recognizes a possibility of a collision of a subject vehicle and a obstacle, and halts the braking control. On the other hand, if a depression amount of the brake pedal by the driver changes to a release side at or over a preset speed, the cruise control unit restarts the halted braking control.

Abstract: A vehicle driving support apparatus in which a cruise control unit starts to blink a hazard light when it is determined that a subject vehicle is stopped by collision prevention control through an automatic braking intervention. The blinking is continued until a predetermined operation input is performed by a driver so as to call the attention of a driver of a following vehicle or the like even if the driver is upset due to a sudden stop of the subject vehicle.
