Abstract: Provided is a parking assistance device capable of reducing inconvenience felt by a driver experienced in automatic parking control during parking at a target vehicle speed corrected to a lower speed at a start of use of automatic parking control, for example. The parking assistance device controls a vehicle speed of the vehicle during parking to assist parking of the vehicle. The parking assistance device increases the vehicle speed of the vehicle during parking in accordance with a behavior during parking or from previous parking of the vehicle.

Abstract: An automatic parking control device is capable of causing a vehicle to correctly reach the next frame without relying on normal parking route regeneration when a determination is made that the vehicle cannot reach the next frame under automatic parking vehicle control along a section route constituting a part of a parking route. When a determination is made whether the next frame is located on an extension of the current section route and the determination result shows that the next frame is located on the extension, the host vehicle travels further. When the determination is made whether the next frame is located on a remaining section of the current section route and the determination result shows that the next frame is located on the remaining section, the host vehicle decelerates earlier, thereby allowing the host vehicle to reach and come to a stop at the next frame.

Abstract: The present invention provides a transmission control device for a vehicle capable of changing a threshold of a shift map for determining shift-up, thereby preventing occurrence of the shift-up during depression of an accelerator and preventing occurrence of a torque interruption. In a transmission control device for a vehicle 1 including a T/M-ECU 50 which automatically performs shift control for switching a plurality of shift gears of a transmission 20 for shift-up or shift-down, the T/M-ECU 50 has a shift threshold setting unit 54 which sets a shift threshold to be used for the shift control, on the basis of an operation plan or a surrounding state of the vehicle 1, and the shift threshold setting unit 54 sets the shift threshold to perform the shift control on the transmission 20 so as not to perform the shift-up of the transmission 20 during acceleration of the vehicle 1.

Abstract: A parking frame for which a parking route cannot be generated is excluded from selection objects by a simple determination. The parking assistance device acquires information on an entrance width of a frame entrance of the parking frame and information on a passage width of a passage, and calculates a minimum projection amount wm in a passage width direction of a vehicle 220 from the parking frame 203 to the passage 205 when a vehicle corner on a front side of the vehicle in an approach direction to the parking frame and on a first side in a vehicle width direction is located at the entrance end on the first side of the parking frame in the frame width direction, and when the vehicle is disposed at a position where the vehicle side part on a second side of the vehicle in the vehicle width direction is in contact with the entrance end on the second side of the parking frame in the frame width direction.

Abstract: Provided is a vehicle control device for allowing the occupant to easily confirm the presence or absence of an obstacle for the own vehicle through a screen image.

Abstract: There is a problem that it takes a long time to park a vehicle because the vehicle has to be returned to a position outside the parking frame and parked. In step S160, the correction judgment unit 142 judges from the necessary correction amounts calculated in steps S140 and S150 and the remaining distance to the re-targeted parking position that is re-recognized, whether or not correction of the parking route with this remaining distance is possible. In a case where it is judged in step S160 that correction with the remaining distance r2 is impossible, the vehicle is stopped in step S171. Even if it is judged in step S160 that the correction is impossible, when the vehicle is moved backward toward the parking frame is parked, the vehicle is obliquely parked in the parking frame and cannot be fit neatly in the parking frame. In step S172, a parking route including a turnabout is regenerated with respect to the re-targeted parking position calculated in step S130 while the stopped state is maintained.

Abstract: An OLT transmits and receives a CMTS/CM apparatus control signal through an apparatus physical management interface which is physically identical to or different from a main signal interface (NNI) and processes the CMTS apparatus control signal by itself. When connection of a new ONU is detected by an ONU apparatus control signal, an IP address is allocated by using the CM apparatus control signal in a manner similar to the CM. The CM apparatus control signal regarding the ONU is transmitted and received by using the IP address and a mutual conversion is performed between the CM apparatus control signal and the ONU apparatus control signal. The ONU processes the ONU apparatus control signal in a manner similar to the ONU based on an ordinary PON standard.

Abstract: A packet forwarding apparatus for connecting a plurality of user terminals to an ISP management server has a management table indicating the relationship between a connection port identifier and specific header information in association with the MAC address of each of the user terminals so that, in a communication protocol procedure executed between each of the user terminals and the ISP management server prior to communication with a wide-area network, the packet forwarding apparatus discards a packet for the user terminal when it is determined that the specific header information cannot be assigned to the user terminal based on the management table.

Abstract: A MVAC spoofed frame or a loop frame generated by a user is prevented from obstructing communication and the source port ID of a fraud is reported to the network administrator. A MAC frame forwarding apparatus adds the input port ID and the source MAC address of a received frame. The MAC frame forwarding apparatus has a frame forwarding management table and a frame discarding management table. The frame discarding management table has a MAC address to be discarded, indicating a received frame to be discarded if the address matches the source MAC address of the received frame, a target port ID, and the number of discarded frames. A management apparatus discards a received frame if the source MAC address matches the MAC address to be discarded and counts the number of discarded frames.

When the BAS/load balancer of the invention sets up a dynamic connection between the user networks, the balancer determines the load balancing target apparatus which is a relay destination using an arbitrary load balancing algorithm for both send and receive communications traffic in the user network.

Abstract: An OLT transmits and receives a CMTS/CM apparatus control signal through an apparatus physical management interface which is physically identical to or different fro a main signal interface (NNI) and processes the CMTS apparatus control signal by itself. When connection of a new ONU is detected by an ONU apparatus control signal, an IP address is allocated by using the CM apparatus control signal in a manner similar to the CM. The CM apparatus control signal regarding the ONU is transmitted and received by using the IP address and a mutual conversion is performed between the CM apparatus control signal and the ONU apparatus control signal.
