A map information output device includes: a rule selector sequentially selecting one road selection rule from a plurality of road selection rules based on route guidance information; a target road selector for (i) selecting a target road for constructing control map information based on the road selection rule selected by the rule selector and a position of a vehicle, and (ii) selecting another target road for constructing control map information based on another road selection rule different from the road selection rule selected by the rule selector, respective for automatic drive control; a map information constructor sequentially constructing the control map information; and a map information output unit sequentially outputting the control map information, which determines the control map information to be output based on whether or not the vehicle is traveling on a route to be traveled.

Map information output device and method to output and select control map information

A map information output device including a map information output unit that outputs control map information for automatic driving control of a vehicle to an automatic driving control unit The map information output device includes: a map storage unit storing an original map for constructing the control map information; a position obtainer obtaining a current position of the vehicle; a map information constructor sequentially constructing the control map information based on the original map of a first range determined with reference to the current position obtained by the position obtainer; and a download processor downloading and storing the original map of a second range, which is a range determined based on the current position and includes the first range, sequentially from a map distribution device outside the vehicle by wireless communication.

Map information output device, automatic driving control system, map information output system, and map information output method

A map data output device includes: a map storage that stores map data that represents lane network information; a position determination portion that determines a current position of a vehicle; a read processing portion that reads the map data of an area established based on the current position; a control map generation portion that generates control map data obtained by adding information to the map; and an output portion that outputs the control map data to a vehicle control device.

Map data output device

In a vehicle control device for performing control to stop and start an engine according to a traveling state of a vehicle regardless of an operation of stopping and starting the engine by a driver, the stopping of the engine is limited based on a starting endurance ability of the engine. Thus, an endurance number of years of a starter can be ensured. If a contribution degree in improving a fuel economy by the stopping of the engine at the time of parking is high, the effect of improving the fuel economy can be suppressed from reducing by prohibiting the automatic stopping of the engineduring traveling. The effect of improving the fuel economy by stopping the engine can be enhanced by ensuring the endurance number of years of the starter.

Vehicle control device

A control apparatus for a vehicle that suppresses degradation of the durability performance of a battery, while improving the fuel consumption of a vehicle. The control includes an engine, a battery that is chargeable with power of the engine, a configurator that sets a start condition for starting an engine according to a state of the battery; and a starter that starts the engine when the start condition is satisfied.

Control apparatus for vehicle, vehicle and method of controlling vehicle

A main ECU () for generating an actual acceleration/deceleration running pattern based on a current running situation of a vehicle, generating a corrected acceleration/deceleration running pattern obtained by elongating an actual acceleration/deceleration period of the actual acceleration/deceleration running pattern when an actual acceleration/deceleration period (T) in the actual acceleration/deceleration running pattern is shorter than a reference acceleration/deceleration period (T) set in advance, and setting the actual acceleration/deceleration running pattern as a best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is not generated and setting the corrected acceleration/deceleration running pattern as the best acceleration/deceleration running pattern when the corrected acceleration/deceleration running pattern is generated, is provided.
