Problems solved by technology

In this case, if the display related to the engine start threshold changes greatly accompanied by a large change in the engine start threshold, the driver cannot grasp the meaning, so there is a possibility of causing discomfort to the driver
In addition, when the display related to the engine start threshold changes without the driver's operation, it may prevent the driver from operating in order to travel within the range where the engine does not start.

Embodiment Construction

[0014] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

[0015] figure 1 It is a diagram showing an example of a configuration of a hybrid vehicle. A hybrid vehicle includes engine 100 , first MG (Motor-Generator) 110 , second MG 120 , power split device 130 , speed reducer 140 , power storage device 150 , drive wheels 160 , ECU (Electronic Control Unit) 170 , and display 172 . In addition, in the illustrated example, the hybrid vehicle is a so-called plug-in type hybrid vehicle, and includes a charger 180 and a charging port 190 .

[0016] Engine 100 , first MG 110 , and second MG 120 are connected to power split device 130 . The hybrid vehicle travels with driving force from at least one of engine 100 and second MG 120 . The power generated by the engine 100 is distributed to two paths by the power split device 130 . That is, one is a path for transmission to drive wheels 160 via speed reducer 140 , and ...

Abstract

Provided is a vehicle state display device in a hybrid vehicle, comprising a display apparatus which outputs display relating to a threshold which represents an engine start condition in a drive state by an electric motor, and a processing device. If the threshold changes, when the threshold has changed due to an operation by a passenger in the vehicle, as well as when the threshold changes due to a factor other than the operation by the passenger in the vehicle, the processing device varies the change state of the display according to the threshold change.

Description

technical field [0001] The present invention relates to a vehicle state display device for a hybrid vehicle. Background technique [0002] Conventionally, a device is known (for example, refer to Patent Document 1). In the device disclosed in Patent Document 1, the economical driving state quantity is graphically displayed as a relative quantity with respect to the engine start threshold. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2010-30536 [0004] However, the engine start threshold may be determined based on various factors, and may vary greatly based on factors not caused by the operation of the vehicle occupant (especially the driver). For example, when the battery temperature is high and the engine is promoted to protect the battery, the engine start threshold may vary greatly. In this case, if the display related to the engine start threshold changes greatly along with the large change of the engine start threshold, the driver cannot grasp the meani...
