The optimum driving information is transmitted from a transmitting unit (724) to the vehicle-mounted device that set the planned traveling information. When the vehicle-mounted device receives the optimum driving information, a presenting unit (715) presents driving support information relating to the planned travel path for the vehicle.

Description

Driving operation support system and driving operation support method

The present invention relates to a driving operation support system, a driving operation support method, a driving operation support program, and a recording medium on which the driving operation support program is recorded.

In recent years, electric vehicles (Electric Vehicle) and hybrid vehicles (Hybrid 注目 Vehicle) have been attracting attention from the viewpoint of reducing environmental impact. Such electric vehicles and hybrid vehicles generally include a storage battery and an electric motor. The electric vehicle is driven using an electric motor as a power source. In addition, the hybrid vehicle travels in combination with two types of power sources, a gasoline engine (internal combustion engine) and an electric motor.

In this way, a hybrid vehicle that travels using both a gasoline engine and an electric motor uses a gasoline engine and an electric motor depending on the traveling state of the vehicle. For example, an electric motor is used when the vehicle starts, and a gasoline engine and an electric motor are used together during acceleration. The vehicle travels using a gasoline engine during normal travel when the vehicle travels at a constant speed. In addition, an electric vehicle or a hybrid vehicle (hereinafter also referred to as “electric vehicle etc.”) collects a part of the kinetic energy that the vehicle has during traveling as electric energy by the regenerative brake mechanism when the vehicle decelerates, Charge the storage battery.

In order to improve the driving fuel efficiency, which is a characteristic of an electric vehicle including charging of a storage battery by such a regenerative brake mechanism, it is necessary to perform driving adapted to the electric vehicle. Because of these needs, various techniques for running suitable for electric vehicles have been proposed (see Patent Documents 1 and 2: hereinafter referred to as “Conventional Examples 1 and 2”).

Here, in the technique of Conventional Example 1, the route to the destination is divided into a plurality of sections, and the vehicle speed pattern for each section is estimated from the road conditions of the route and the driving history of the driver. Then, based on the vehicle speed pattern and the fuel consumption consumption specification of the engine, the engine and motor operation schedules are set for each section so that the fuel consumption amount to the destination is minimized.

Further, in the technique of Conventional Example 2, test traveling fuel consumption data for each driving pattern obtained from the traveling test of the hybrid vehicle is stored in advance. Then, actual traveling fuel consumption data for each driving pattern is measured during actual traveling, and the actual traveling fuel consumption data is compared with the most efficient test traveling fuel consumption data in the driving pattern. And the driving operation in actual driving | running | working is evaluated and the information regarding the said driving operation is displayed.

JP 2000-333305 A JP 2007-210487 A

In the technique of Conventional Example 1 described above, the operation schedule of the engine and motor to the destination is set. For this reason, the technology of Conventional Example 1 cannot provide driving operation support information to the driver during actual driving.

Moreover, in the technique of the above-described Conventional Example 2, since the driving operation in the actual driving is evaluated based on the test driving fuel consumption data for each driving pattern obtained from the driving test, the actual driving route having different situations. It is hard to say that it is possible to evaluate the excellent driving in Japan. Furthermore, in the technique of Conventional Example 2, since the driving operation is evaluated after the driving operation, the driving operation support information in the future travel route is not provided to the driver in real time.

In addition, since the technologies of Conventional Examples 1 and 2 are technologies related to hybrid vehicles, they cannot be applied to electric vehicles that do not use a gasoline engine as a power source. Furthermore, since the technologies of the conventional examples 1 and 2 do not monitor information related to actual charging / discharging of the storage battery in real time during driving when setting a driving schedule and evaluating driving operations, the driving fuel consumption is improved. It is hard to say that the technology is optimal for running that is adapted to be more effective.

For this reason, taking into account the discharge from the storage battery when the vehicle is starting or accelerating, the charging of the storage battery by the regenerative brake mechanism, etc., support for driving operations adapted to electric vehicles and hybrid vehicles in the future actual driving route There is a need for a technology that can provide information in real time while driving.
