When an own vehicle Vcrosses an opposite traffic lane Rat an intersection to make a right turn, an ECUsuch as a vehicle control device detects a presence of a crossing person P crossing a crosswalk CW existing near the intersection on a road Rwhich the vehicle Vis directed to enter by making the right turn, detects a size of a space between the crosswalk SP on which the detected crossing person P crosses and the opposite traffic lane, and when performing a control for braking the vehicle Vso as to avoid a collision of at least the vehicle Vwith the crossing person P, changes a timing to perform the control for braking the vehicle Vbased on the detected size of the space SP up to the crosswalk CW.

Vehicle control device

[Problem] To enable effectively utilizing electrical energy of a vehicle and effectively preventing early deterioration of the second electricity storage unit. [Solution] Provided is a vehicle control device for supplying electricity to an electrical load component of a vehicle. The vehicle control device comprises: a first electricity storage unit () capable of holding electricity over a long period of time; a second electricity storage unit () capable of more rapid charge and discharge than the first electricity storage unit (); an ignition switch detection means () for detecting an operational state of an ignition switch of the vehicle; a voltage detection means () for detecting a voltage of the second electricity storage unit (); and a discharge means () for, when the ignition switch detection means () detects that a turn-off operation of the ignition switch is performed, and the voltage detection means () detects that the voltage of the second electricity storage unit () is equal to or greater than a preset reference value, discharging electricity stored in the second electricity storage unit ().

A power-supply control apparatus of a vehicle comprises a first electricity-storage device to supply electric power to a starter for starting engine, a generator to convert kinetic energy of the vehicle during a vehicle deceleration to electric energy for energy recovery, a second electricity-storage device coupled to the generator to store the electric power from the generator thereat, a feeder circuit coupling the second electricity-storage device to an electric load with a relatively-small electric-load capacity via a DC/DC convertor, a coupling line coupling the second electricity-storage device to the first electricity-storage device via a coupling relay, and a controller to control the electric power passing through the feeder circuit and the coupling line, wherein the controller executes a control to make the coupling relay on the coupling line in an OFF state when the starter operates.
