no. 1 Embodiment approach

[0040] Next, the fuel-saving driving support system according to the first embodiment of the present invention will be described based on the drawings.

[0041] figure 1 It is a configuration diagram showing the overall configuration of the fuel-saving driving support system of the present embodiment. Such as figure 1 As shown, the fuel-saving driving support system is composed of an in-vehicle device 10 mounted on a vehicle and a personal computer 20. The personal computer 20 displays information determined by the engine speed and the vehicle speed based on the stored data stored in the in-vehicle device 10 The distribution state or setting of the driving state can determine the boundary of each driving state area divided from the viewpoint of good fuel efficiency and poor fuel efficiency.

[0042] However, in this embodiment, an example is described in which the boundary of the area dividing each driving state is set in the personal computer 20, but the boundary of the area divid...

no. 2 Embodiment approach

[0082] Next, the fuel-saving driving support system according to the second embodiment of the present invention will be described. Figure 7 It is a configuration diagram showing the configuration of the in-vehicle device of the fuel-saving driving support system of the present embodiment.

[0083] The fuel-saving driving support system of the present embodiment and the fuel-saving driving support system of the first embodiment have in common in that the state of the vehicle determined by the engine speed and the vehicle speed belongs to the graph with the engine speed and the vehicle speed as two axes. The ratio of each area is calculated and the evaluation score is calculated.

[0084] Here, when the gradient of the road on which the vehicle travels changes, or when the vehicle is a cargo transportation vehicle such as a truck or a trailer, the running resistance changes greatly in a loaded state with cargo and an empty car without cargo. In such a case, if the area divided by th...

no. 3 Embodiment approach

[0111] Next, the fuel-saving driving support system according to the third embodiment of the present invention will be described. Picture 10 It is a configuration diagram showing the overall configuration of the fuel-saving driving support system of the present embodiment. The description of the same configuration as that of the fuel-saving driving support system in each of the above-mentioned embodiments is omitted by assigning the same reference numerals.

[0112] When a vehicle merges at the entrance or junction of the expressway from the ramp, service area (SA) or parking area (PA) connecting the expressways to the main road of the expressway, the driver During the traveling on the connecting road provided for merging, the speed of the own vehicle needs to be matched with the speed of the vehicle traveling on the main road. Therefore, it is necessary to accelerate the vehicle abruptly compared to the normal time, and as the state of the vehicle, the engine has to be rotated ...

Abstract

A fuel-cost-saving driving support system determines mutually adjacent at least three areas from a good-fuel-cost driving state area to a poor-fuel-cost driving state area in a figure taking an engine speed and a vehicle speed as two axes, then calculates a ratio of the driving states determined by the actually detected engine speed and vehicle speed belonging to the each area, and informs information representing a fuel-cost-saving driving grade based on the calculated ratio, therefore, the fuel-cost-saving driving support system can arouse enthusiasm of a driver for further raising the grade, and can anticipate a further suppression effect of fuel consumption.

Description

Technical field [0001] The present invention relates to a fuel-saving driving support system that supports the driver of a vehicle to perform fuel-saving driving. Background technique [0002] For example, Patent Document 1 discloses an in-vehicle device that determines the degree to which energy-saving driving is performed. The energy-saving driving is driving in at least one of a state in which exhaust gas emission is suppressed or a state in which energy consumption is suppressed. . [0003] In this in-vehicle device, the degree of energy-saving driving is determined from a number of different viewpoints as follows, namely, whether the accelerator position is appropriate, whether the appropriate gear is used, to what degree the air conditioner is used, In a state where the fuel injection amount is zero by closing the accelerator, to what extent, whether the vehicle is traveling at an appropriate speed less than a predetermined speed, or whether it is heading toward the destinat...
