Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention analyzes operation data of a vehicle and proposes improvements to a vehicle driver and a vehicle manager for fuel-saving driving suitable for each position. An information providing system and method.

[0002]

2. Description of the Related Art Fuel consumption is one of the barometers for driving a vehicle. The fuel consumption amount is a very important barometer because it is reflected in the transportation cost of commercial vehicles such as large trucks in particular, and the driver of the vehicle is required to operate with fuel efficiency. Instructing the driver to drive the vehicle in a fuel-saving manner also for the vehicle manager, and performing schedule management and travel route setting (so-called operation planning) so that the driver can drive efficiently in a fuel-efficient manner. Is required.

In view of the above points, there is a method of analyzing the driving state of the driver from the viewpoint of fuel consumption and providing the analysis result to the driver. A typical example thereof is Japanese Patent Laid-Open No. 2000-
247162.

Japanese Unexamined Patent Publication No. 2000-247162 is a method of acquiring a driving state obtained from a vehicle, analyzing it from the viewpoint of fuel consumption and safe driving based on the acquired data, and providing the result to the driver. is there.

On the other hand, by using a travel route setting system such as a car navigation system that sets a travel route that can reach the destination on the earliest route in time, the optimal transportation schedule of the goods is taken into consideration. , There is also a method to provide the administrator with an efficient operation.

[0006]

However, in the above two methods, both of them are only provided to either the driver or the manager. Therefore,
When the analysis from the viewpoint of fuel consumption is performed, it is only the analysis from one of the standpoints, not the analysis from the viewpoints of both the driver and the manager.

In practice, however, the fuel consumption provides a more accurate analysis result to the driver and the manager, and an optimum result, unless a complex analysis from the viewpoints of both the driver and the manager is made. It is difficult to provide a good improvement plan.

For example, when the fuel consumption is increasing due to a long idling time, an improvement from the viewpoint of the driving method of thoroughly instructing the driver to stop the engine when the vehicle is stopped, and avoiding a congested road There are improvements in both aspects, from the viewpoint of the operation plan that the idling operation is reduced by operating the vehicle. Therefore, even if you make an improvement proposal to only one of them,
Sufficient results cannot be obtained.

Further, in the conventional method, only the analysis result is presented, and it is unclear how to deal with the analysis result. Not done.

In addition, in the case of using a known travel route setting system such as a car navigation system, only the arrival time to the destination is calculated, and it is difficult to set the travel route according to the reality such as traffic congestion. Is. There is also a method of considering traffic congestion using VICS etc., but this is "current" traffic congestion and is different from "when the vehicle is operating" traffic congestion based on the operation plan. It is not suitable.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the process flow of the present invention will be described in detail with reference to the system configuration diagram of FIG. 1 and the flow chart diagram of FIG.

The driver operates the vehicle 12 based on an operation plan predetermined by the manager (S100). At the time of operation in S100, operation data of the vehicle 12 is stored in a storage unit (not shown) provided in the vehicle 12 in advance. The operation data acquired at this time includes vehicle speed, accelerator opening, engine speed, longitudinal acceleration of the vehicle 12, usage of auxiliary brakes, and the like. In this embodiment, the operation data is stored in the storage means (not shown) as described above,
The case where the operation data is transmitted to the data acquisition means 2 of the driving information providing system 1 after the operation will be explained. Operation data may be transmitted.

After the operation of the vehicle 12 in S100, operation data is transmitted from the storage means (not shown) of the vehicle 12 to the data acquisition means 2 of the driving information providing system 1. The data acquisition means 2 acquires operation data and stores it in the operation information database 7 (S110).

The driving method analyzing means 3 drives the driver based on the operation data stored in the driving information database 7 from the viewpoint of the driver in fuel consumption (the viewpoint of the driving method).
Analysis of a predetermined analysis target is performed from (S12
0). In this embodiment, the maximum vehicle speed, the fuel consumption ratio during idling, the engine speed during gear shifting, the selection of the cruising gear stage, the accelerator operation during high-speed running, the brake pedal depression, and the usage of the auxiliary brake are analyzed. The case will be described below. The specific analysis method is not limited to the method shown in this embodiment, and analysis may be performed by other methods.

For the maximum vehicle speed, the highest speed data is used by using the vehicle speed in the operation data stored in the driving information database 7 in S110. This is an analysis item in view of the fact that the higher the maximum vehicle speed, the worse the fuel consumption. For example, the maximum vehicle speed is 80 per hour
If it is less than or equal to km, it is judged as good, and if it is more than that, it is judged as bad.
In addition to this, the maximum vehicle speed may be calculated by calculating an average vehicle speed and comparing the average vehicle speed with a predetermined reference value to evaluate the fuel consumption amount.

The fuel consumption ratio at idling is
This is an analysis item in view of the fact that the longer the idling time, the worse the fuel consumption. In particular,
It is determined whether the engine is idling or not by using the accelerator opening, engine speed, and vehicle speed in the operation data stored in the operation information database 7, and the fuel consumption at idling becomes the total fuel consumption. It is done by calculating the ratio. That is, when the accelerator opening is at a predetermined ratio, and the vehicle speed is 0 km / h and the engine speed is 0 rpm or more, it is determined that the engine is idling, and the fuel in that state is determined. Consumption (eg 15 liters) to total fuel consumption (eg 1000 liters)
Divide by. The fuel consumption amount is calculated using the engine electronic control unit. In the above example, the fuel consumption ratio during idling is 1.5%. For example, if the fuel consumption in idling is less than 1%, it is good, 1%
If it is less than 2% or more, it is determined to be medium if it is more than 2%. The determination method during idling is not limited to this method, and other methods may be used.

As for the engine speed during gear shifting, the engine speed during gear shifting is detected and accumulated.
Fuel consumption is evaluated by comparing the most frequent engine speed during gear shifting with a predetermined reference value. This is an analysis item in view of the fact that the fuel consumption deteriorates as the engine speed during gear shifting increases.

As a concrete determination method, the engine speed is detected at the time of gear shift, and the frequency is accumulated for each speed within a certain range, and the frequency is calculated as the most frequent engine speed at that time. The fuel consumption is evaluated by comparing with a predetermined reference value. For example, it is determined that when the engine frequency that is most frequently used during gear shifting is less than 1100 rpm, it is good, and when it is 1100 rpm or more and 1300 rpm or less, it is bad and when it exceeds 1300 rpm.

The selection of the cruising gear is to evaluate the fuel consumption based on the frequency of use of the gear during traveling. This is an analysis item in view of the fact that the fuel consumption increases as the gear position during traveling increases.

As a concrete determination method, the current gear stage is detected at predetermined time intervals, the frequency thereof is calculated, and the most frequently used gear stage at that time is compared with a predetermined reference value. To evaluate fuel consumption. For example, it is determined that the gear that is most frequently used is 5th gear, good, 4th gear is medium, and 3rd gear is bad.

The accelerator operation during high speed traveling is to detect a change in the accelerator opening. This is an analysis item in view of the fact that if the accelerator opening changes a lot, the accelerator is depressed and released a lot when the vehicle 12 travels, which leads to deterioration of fuel consumption.

As a specific determination method, first, the frequency of changes in the accelerator opening during a predetermined distance or a predetermined time is detected, and the frequency is compared with a predetermined reference value to determine the fuel consumption. Make an evaluation. For example, if the frequency of the change in the accelerator opening for a predetermined distance or time is 1 to 4 times, it is good, if it is 5 to 9 times, it is medium, and if it is 10 times or more, it is bad.

As for how to press the brake pedal, the longitudinal acceleration of the vehicle 12 is detected to detect the most frequent longitudinal acceleration of the vehicle 12 during deceleration by the brake pedal, and a predetermined reference value is determined. Fuel consumption is evaluated by comparing with. This is an analysis item in view of the fact that a large amount of sudden braking leads to deterioration of fuel consumption. For example, if the magnitude of the longitudinal acceleration of the most frequent vehicle 12 is smaller than 0.01 G,
If it is 0.01 G or more and 0.1 G or less, it is determined to be bad if it is larger than 0.1 G. As a method of detecting the longitudinal acceleration of the vehicle 12, an acceleration sensor may be used for direct detection, or a vehicle speed sensor may be used for calculating a change in vehicle speed per unit time.

Regarding the usage of the auxiliary brake, the fuel consumption is evaluated by calculating the ratio of the auxiliary brake operating time to the engine braking operating time and comparing it with a predetermined reference value. This is an analysis item in view of the fact that heavy use of engine brakes and refraining from using auxiliary brakes lead to deterioration of fuel consumption. For example, if the ratio of the auxiliary brake actuation time to the engine brake actuation time is less than 10%, it is determined as good if it is 20% or more and 30% or more, and medium if it exceeds 30%. still,
The auxiliary brake is an exhaust brake or a retarder.

The operation plan analysis means 4 analyzes the operation plan of the vehicle 12 based on the operation data stored in the operation information database 7 in advance from the manager's viewpoint in fuel consumption (operation plan viewpoint). Analyze the target (S13
0). The analysis target at this time includes, for example, the frequency of traffic congestion on the vehicle operation route, dead time in the vehicle operation plan, and departure / arrival time during vehicle operation.

As for the frequency of traffic congestion on the vehicle operating route, the vehicle speed in the operating data is used to determine the operating time at a predetermined vehicle speed (for example, 15 km / hour or less) (for example, 12 km).
The ratio of the time) to the total operation time (for example, 100 hours) is calculated. In the above example, the frequency of traffic congestion is 12%. After calculating the ratio of the operating time at the predetermined vehicle speed to the total operating time, if the ratio exceeds the predetermined ratio, it is determined that the frequency of congestion is high and the vehicle operation route Will be proposed for change.

The dead time in the vehicle operation plan is determined by the accelerator opening, the engine speed, and the vehicle speed in the operation data to determine whether or not the engine is idling. Calculate the ratio to. After calculating the ratio of the time when idling to the total operating time,
If the ratio exceeds a predetermined ratio, it is determined that the operation plan including waiting for cargo, unloading, etc. is wasteful, and a review of the vehicle operation plan is proposed.

The departure / arrival time during vehicle operation is calculated by using the vehicle speed during high-speed traveling, which exceeds a predetermined vehicle speed (for example, 80 km / h). That is, if the departure and arrival times of the vehicle operation plan are unreasonable, it becomes necessary to increase the vehicle speed during high-speed traveling. Therefore, the time over which the vehicle speed exceeds a predetermined vehicle speed (80 km / h in the above example) is integrated, and if the time is outstanding, it is determined that the departure / arrival time of the vehicle operation plan is unreasonable. , Suggesting a review of departure / arrival times in vehicle operation plans.
