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 source controller (40) for controlling a vehicle (1) that travels using a power source system (30) that includes a first power source (31) into or from which a first electrical power is inputted or outputted, and a second power source (32) into or from which a second electrical power is inputted or outputted, the second power source (32) having lower capacity than the first power source, but a higher output; wherein the power source controller (40) is provided with a selecting means (40) and a control means (40). The selecting means (40) selects, in accordance with a property required for the vehicle, a desired travel mode from a plurality of travel modes having different share ratios of first power relative to the power demanded by the power source system. The control means (40) controls the first power source and the second power source so that the first power is inputted and outputted at a share ratio corresponding to the travel mode.

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...
