Problems solved by technology

[0015] However, in the above-mentioned conventional technology, although the current SOC can be grasped, when the SOC is restored by charging by regenerative power generation during driving in the HV driving mode, the driver is not prompted when to return to the EV driving mode again. information, it is impossible to predict the switching of the driving mode

Embodiment

[0056] Embodiments of an SOC display device for a hybrid vehicle (hereinafter simply referred to as "SOC display device") to which the present invention is applied will be described below.

[0057]The SOC display device of the embodiment is installed in an engine-electric hybrid vehicle having a plug-in charging function and an EV driving mode in which the vehicle mainly uses only a motor, for example, a car such as a passenger car.

[0058] figure 1 It is a block diagram schematically showing the configuration of a powertrain and the like of a hybrid vehicle provided with the SOC display device of the embodiment.

[0059] Such as figure 1 As shown, the vehicle has an engine 10, a torque converter 20, an engine clutch 30, a front-to-rear forward switching part 40, a transmission 50, an output clutch 60, a front differential 70, a rear differential 80, a transfer clutch 90, a motor generator 100. Engine power hybrid of engine control unit 210, transmission control unit 220, m...

Abstract

The present invention relates to an SOC display device for a hybrid vehicle. Provided is an SOC display device for a hybrid vehicle capable of intuitively grasping a current SOC and a change in a driving mode corresponding to a change in the SOC. The SOC display device (411) of a hybrid vehicle having an EV running mode and an HV running mode has a display device that displays a moving mark (412) that moves according to an increase or decrease of the SOC and a fixed mark arranged along a moving range of the moving mark. Markers (413a) to (413i), wherein the moving markers move between positions respectively corresponding to the maximum value and the minimum value of the SOC range used in each driving mode, and the fixed markers have corresponding to switching from the EV driving mode to the HV driving mode. A first flag (413h) and a second flag (413f) corresponding to switching from the HV running mode to the EV running mode.

Description

technical field [0001] The present invention relates to an SOC display device for displaying the SOC of a hybrid vehicle having an EV driving mode, and more particularly to an SOC display device capable of intuitively grasping the current SOC and the change of the driving mode corresponding to the change of the SOC. Background technique [0002] An engine-electric hybrid vehicle (HV) has an engine and a motor generator as driving power sources, and uses electric power generated and charged to a battery when using regenerative brakes, etc., to perform motor assist during acceleration, etc. [0003] In recent years, plug-in hybrid vehicles (PHEVs) have been gaining popularity. For example, this type of hybrid vehicle is provided with a function of charging from an external power source such as a household power supply or a commercial power supply. Fields of application for electric vehicle (EV) driving modes that can be driven using a motor generator. [0004] In the plug-in ...
