  • Publication number: 20200164841
    Abstract: Driving support ECU transmits a communication connection request to a help net center HNC when a driver of a vehicle has been determined to be in an abnormal state where the driver loses an ability to drive the vehicle, and when the communication connection to the help net center HNC has been established, the driving support ECU transmits the help signal (the positional information of the vehicle) and decelerates the vehicle at a constant deceleration to make the vehicle stop. On the other hand, when the communication connection to the help net center HNC has not been established, the driving support ECU makes the vehicle travel at a constant speed. Accordingly, it is possible to make the vehicle stop under a situation where the help net center HNC recognizes the vehicle position inside which the driver who has been determined to be in the abnormal state is.

    Abstract: A parking lock device includes a parking gear, a parking pawl, a parking cam, a solenoid actuator, and a power conversion mechanism. The power conversion mechanism is configured to convert reciprocal motion of the plunger to rotary motion of the parking cam in one direction. When the parking cam rotates, a position of a cam surface of the parking cam that abuts the parking pawl is changed, so as to alternately switch between a locked position where rotation of the parking gear is stopped and an unlocked position where meshing between the parking gear and the parking pawl is canceled. A stroke amount of the plunger is reduced in a range where the parking cam can rotate. In this way, the parking lock device can be downsized. Therefore, mountability of the parking lock device on a vehicle is improved.

    Abstract: A cylinder head (3) is formed with a pre-chamber (12) surrounded by a thin pre-chamber wall (11) sticking out from the inside wall surface of the cylinder head (3) to the inside of a main combustion chamber (5). Inside the pre-chamber (12), the electrode of a spark plug (15) is arranged. When the spark plug (15) is used to burn the air-fuel mixture inside the pre-chamber (12), jet flames are ejected from the communication holes (13) to the main combustion chamber (5). The thin pre-chamber wall (11) is formed into a two-layer structure of an outside wall (11a) facing the main combustion chamber (5) and an inside wall (11b) facing the pre-chamber (12). The inside wall (11b) is formed by a material with a higher heat conductivity than the outside wall (11a).
