  • Patent number: 10030597
    Abstract: A vehicle speed limit apparatus includes a processor configured to calculate a demand value, calculate a pre-correction upper limit value based on a limit acceleration, correct the pre-correction upper limit value based on a first accumulated value to calculate a first upper limit value, correct the pre-correction upper limit value based on a maximum drive force of a drive force generation apparatus and the current acceleration to calculate a second upper limit value, select the smaller of the demand value and the second upper limit value when the first upper limit value exceeds a predetermined threshold corresponding to the maximum drive force, and select the smaller of the demand value and the first upper limit value when the first upper limit value does not exceed the predetermined threshold, and control the drive force generation apparatus to generate the drive force corresponding to the selected value.

  • Patent number: 9602386
    Abstract: First node stores completion information on second node that is adjacent to the first node, the completion information indicating whether or not a route between a target destination and the second node has been constructed using an address with a specified size; acquire a first address with the specified size that specifies the first node, and transmits to adjacent nodes the completion information on the first node indicating that the route between the target destination and the first node has been constructed using an address with a specified size, when the completion information on the second node has indicated that the route between the target destination and the second node has been constructed using the address with the specified size and when the first address has been acquired; and transmits a data frame by using the first address, when the completion information on the first node is transmitted.
