Embodiment Construction

[0094] Hereinafter, an embodiment in which the present invention is applied to a vehicle 1 including a motor generator 10 will be described as an example of a form for implementing the present invention with reference to the drawings.

[0095] (1) Structure of the vehicle

[0096] First, refer to figure 1 , the configuration of the vehicle 1 according to the present embodiment will be described. here, figure 1 It is a block diagram showing an example of the configuration of the vehicle 1 according to the present embodiment.

[0097] Such as figure 1 As shown, vehicle 1 includes motor generator 10 , axle 21 , wheels 22 , power supply system 30 , and ECU 40 as a specific example of "power supply control device (ie, selection unit, adjustment unit, and control unit)".

[0098] During traction operation, motor generator 10 is mainly driven by electric power output from power supply system 30 , thereby functioning as an electric motor that supplies power to axle 21 (that is, ...

Abstract

A power supply control device (40) controls a vehicle (1) traveling using a power supply system (30) including a first power supply (31) for inputting and outputting first electric power and a second electric power supply Both the input and output of the second power supply (32), which has a smaller capacity than the first power supply but has a larger output, the above-mentioned power supply control device (40) has: a selection unit (40), which is required for the power supply system from the first power supply Among the multiple travel modes that require different sharing ratios of electric power, the desired travel mode is selected according to the characteristics required by the vehicle; The input and output of the first electric power and the second electric power are performed according to the corresponding sharing ratio.

Description

technical field [0001] The present invention relates to the technical field of, for example, a power source control device for controlling a vehicle running using a power source system including two types of power sources. Background technique [0002] Vehicles (for example, electric vehicles and hybrid vehicles) equipped with a power supply system including two types of power sources have been proposed (see Patent Documents 1 and 2). As two types of power sources, for example, a power source capable of discharging (that is, outputting) constant power for a long period of time and a power source capable of rapid charging and discharging (ie, inputting and outputting) are used. [0003] Here, Patent Document 1 discloses a control method in which the battery outputs all of the discharge request output when the discharge request output requested from the power supply device is equal to or less than the maximum output of the battery during traction operation. Furthermore, Paten...
