An eco drive support apparatus which reports the eco degree of the driving operation of a vehicle by displaying a state relative to a judgment threshold which varies corresponding to the drive state of the vehicle. The apparatus has a power train ECU which computes the judgment threshold and an eco drive state amount expressing a ratio to the judgment threshold on the basis of the drive state of the vehicle and a meter ECU which indicates the eco drive state amount on the basis of information transmitted from the power train ECU. The power train ECU transmits the eco drive state amount to the meter ECU.

Eco-drive assist apparatus, eco-drive assist information generating apparatus, eco-drive assist information calculation apparatus, eco-drive state display apparatus, eco-drive assist system, and eco-drive assist information calculation method

An eco-drive assist apparatus displays a quantity of eco-drive that indicates a degree of ecology and/or economy in driving in a hybrid vehicle equipped with an engine and a motor. The apparatus includes a first part configured to calculate the quantity of eco-drive on the basis of a vehicle power generated in the vehicle, and a second part configured to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an eco-drive judgment threshold value that indicates whether the vehicle is in an eco-drive state and as a relative quantity to an engine startup threshold value that indicates whether the engine has been started up and configured to cause the quantity of eco-drive to be displayed on a boundary of the engine startup threshold value or displayed at a position where the quantity of eco-drive is worse than the engine startup threshold value when the engine has been started up. The second part causes the quantity of eco-drive to be displayed at a position where the quantity of eco-drive is better than the engine startup threshold value when the engine has been started up and a driver's operation needs no vehicle power.

Eco-drive assist apparatus and method

An eco-drive assist apparatus that displays a quantity of eco-drive that indicates a degree of ecology and/or economy in driving in a hybrid vehicle equipped with an engine and a motor, includes: a first part configured to calculate the quantity of eco-drive on the basis of a vehicle power generated in the vehicle; and a second part configured to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an eco-drive judgment threshold value that indicates whether the vehicle is in an eco-drive state and to cause the quantity of eco-drive to be displayed in a graphic manner as a relative quantity to an engine startup threshold value that indicates whether the engine is started up. The second part controls a display of the quantity of eco-drive in the graphic manner as the relative quantity to the engine startup threshold value on the basis of a first display change threshold value that changes the display from a first display showing that the engine has not been started up to a second display showing that the engine has been started up and a second display change threshold value that changes the display from the second display to the first display. The first display change threshold value is the engine startup threshold value.

There is provided a gateway apparatus that controls a forwarding process of frame data between multiple communication channels, said gateway apparatus including a search engine that is respectively provided for each of the multiple communication channels to route the frame data between the multiple communication channels, and a first storage portion that is respectively provided for each of the multiple communication channels to temporarily stores the frame data routed.

Gateway apparatus and routing method

A driving support apparatus supports a driver in driving a vehicle. The driving support apparatus determines a state of the vehicle by collecting information concerning an operating condition of the vehicle, determines a plurality of optimum operations of the vehicle to achieve a corresponding objective based on the determined state, and arbitrates the determined optimum operations.
