Abstract: Provided is a vehicle control system for avoiding a collection between a right-turning vehicle and a straight-through vehicle without decreasing comfort for an occupant. In the system, a first vehicle V1 and a second vehicle V2 retain high-precision map data for identifying a traveling lane. When the first vehicle V1 traveling in an autonomous driving mode intends to turn right from a right turn lane at an intersection ahead based on the high-precision map data, the first vehicle V1 transmits a right turn notification indicating the intention to turn right to nearby vehicles using vehicle-to-vehicle communications. When the second vehicle V2 traveling in an autonomous driving mode intends to travel straight at an intersection ahead, the second vehicle V2 recognizes a right-turning vehicle in an oncoming lane at the intersection upon receiving the right turn notification from the right-turning vehicle, and performs a predetermined control for collision avoidance.

Abstract: A vehicle system includes: a map processing unit that creates local map data based on high accuracy map data and a position of an own vehicle; and an autonomous driving control unit that creates a travel plan for autonomous traveling of the own vehicle based on the local map data and controls traveling of the own vehicle according to the travel plan. The map processing unit creates multiple pieces of transmission data by dividing the local map data so as to correspond to regions on a map and transmits the multiple pieces of transmission data to the autonomous driving control unit. The map processing unit changes a shape and a size of the region on the map corresponding to each piece of transmission data based on selection information which decides a travel mode.

Abstract: A data compression method is used for compressing data indicating a gradient of a route.

Abstract: In an active noise control method of the present invention, a noise detection signal from a noise referring microphone which detects ambient noise is inputted into noise processing units of different types to produce noise silencing signals. A selected noise silencing signal is inputted into a receiver or a speaker together with a reception signal via an adder, so that a regenerated tone from the noise silencing signal silences the ambient noise, When a nonconformance detecting unit judges that the selected noise silencing signal exceeds a predetermined range, the corresponding noise processing unit is judged to be incompatible, and a switch control unit controls a switch to select another one of the noise processing units.

Abstract: Speech encoding using searching of a code book for a code that matches an input speech signal, and speech decoding using the code book are disclosed. A random series of code samples is stored in a buffer memory such as a ring buffer memory, and a basic vector generation unit generates basic vectors by applying an arbitrary shift to each of code series retrieved from the random series. Generation of the basic vectors may be performed according to, for example, an overlapping vector generation process. A code book generation unit extends the basic vectors contained in a basic vector unit according to a structuring process so as to produce a tree-structured delta code book. The basic vector generation unit may extend the basic vectors based on pitch parameters or a center clipping threshold.
