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.

A vehicular electronic control apparatus includes a vehicle control section and a unit control section. The vehicle control section controls a function dependent on a vehicle equipment. The unit control section that controls a function of a unit provided in a vehicle. The vehicle control section and the unit control section are disposed in independent hardwares and software platforms, respectively.

Vehicular electronic control apparatus and method for controlling vehicle

A vehicle control section is operable to control the vehicle based on information on a degree of risk in a risky point through which the vehicle is predicted to drive.

Vehicle control apparatus, vehicle control method and vehicle slip suppressing apparatus

A vehicle controller controls an operation of an engine of a vehicle when the engine is started with a remote command. The vehicle controller decreases the number of idle revolutions of the engine, supplies diluted fuel to the engine, uses only a few cylinders of the engine, changes parameters used in detecting and preventing knocking of the engine, controls the windows or curtains of the windows of the engine to increase the efficiency of air conditioning, and supplies lesser power to in-vehicle devices.
