A gradient information calculating system includes a first calculating unit (14) that detects three-dimensional location information through autonomous navigation, and calculates a first gradient value (θb, B), based on a distance (m) traveled, and an on-plane distance (L1) obtained by projecting the distance (m) traveled on a horizontal plane, a road map information storing unit (17) that stores road map information that represents each road by nodes of which the location information is known, and a link that connects the nodes, a second calculating unit (16) that estimates elevations of the nodes from previously measured elevation data, and calculates a second gradient value (A), based on a difference in elevation between the nodes and the length of the link, and a gradient data selecting unit (19) that selects one of the first and second gradient values to be adopted as a gradient value of the link, according to a difference between the first and the second gradient values.

A hybrid vehicle includes a regenerative charging area detection section, a recovery loss estimation section, and a motor use ratio increase section. The regenerative charging area detection section detects arrival of a regenerative charging possible area in which a regenerative charging from a motor to a battery is possible. The recovery loss estimation section estimates a recovery loss of the regenerative charging based on a regenerative charge amount in the regenerative charging possible area and a current remaining battery amount in response to detection by the regenerative charging area detection section. In response to estimation by the recovery loss estimation section, before the arrival at the regenerative charging possible area, the motor use ratio increase section increases a use ratio of the motor so as to decrease a remaining battery amount while limiting the temperature of the battery to a predetermined temperature range.
摘要:
A site registering device that registers a site allowing charging where a vehicle battery can be charged, the device including: a position acquisition unit that acquires position information on a charging site where charging of the battery has been conducted; and a registering unit that specifies, on the basis of an actual charging result in the charging site, a category to which the charging site belongs among a plurality of categories, associates the charging site with the specified category and the position information, and registers the thus associated charging site as the site allowing charging.
摘要:
A power supply control device including: traffic information acquisition means for acquiring traffic information for roads in the vicinity of the charging station; and control means for controlling an amount of power which is to be supplied to the charging station based on the traffic information (particularly, a traffic flow of vehicles having possibility of using the charging station) acquired by the traffic information acquisition means. An information provision device including: charging station information acquisition means for acquiring information on charging stations; traffic-flow acquisition means for acquiring a traffic flow of vehicles using external electrical energy in the vicinity of each charging station on which the information is acquired by the charging station information acquisition means; and charging station determination means for determining a charging station on which the information is to be provided among the charging station based on the traffic flow acquired by the traffic-flow acquisition means.
摘要:
A road information acquisition device includes: a surface elevation acquisition unit that obtains a surface elevation; a road information acquisition unit that calculates first road information relating to a travel route to be traveled by a host vehicle on the basis of the surface elevation; and a structure determination unit that determines whether or not a structure exists on the travel route, wherein, when the structure determination unit determines that the structure exists on the travel route, the road information acquisition unit obtains second road information, which is different from the first road information, relating to a point at which the structure exists on the travel route.
