Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving condition evaluation apparatus for a vehicle, which evaluates a driving condition of a vehicle which changes depending on the skill of a driver in driving operation.

[0002]

2. Description of the Related Art In recent years, as an engine capable of improving fuel efficiency and reducing the content of harmful substances in exhaust gas in response to deterioration of the global environment such as air pollution caused by vehicle exhaust gas, fuel such as gasoline or light oil is installed in a cylinder. The number of vehicles equipped with in-cylinder injection type engines that directly supply air has increased rapidly. Furthermore, the number of hybrid vehicles capable of further reducing fuel consumption and exhaust gas amount is gradually increasing.

[0003]

In these vehicles, the amount of fuel consumption and the amount of exhaust gas are reduced as compared with the conventional vehicle. It greatly changes depending on the skill of the driving operation technology. However, since a driver can only subjectively judge a driving state based on his / her driving operation technology, even if a certain driver feels that the driving state is friendly to the earth (environment), the driver cannot objectively view the earth. It may be an unfriendly driving condition.

Further, as described in JP-A-2-227611 and JP-A-9-50547, the operating state of a vehicle is detected, and this operating state is compared with an operating state stored in advance. A warning device that warns a driver when the driving state is determined to be dangerous is disclosed.
These prior arts compare the detected driving information with a certain reference value to determine whether or not the vehicle is in a dangerous driving state. Even if the driving information is somewhat dangerous, the driving information is less than the reference value. In this case, the driver is not warned, and the driver is not notified that the driving state is somewhat dangerous by warning or display. Therefore, in such a case, although the driver needs to avoid a somewhat dangerous driving state, the driver not only mistakenly recognizes that the driving state is not dangerous, but also is satisfied with the current driving state and Dangerous driving conditions will be continued.

[0005] As described above, the method for judging the operating state in which the detected operating information is compared with a certain reference value and the driver is contacted only when the value is larger than this reference value is described in the above-described cylinder injection type engine. Considering the case where the present invention is applied to a method for determining whether or not the vehicle is in an environment (environmental) friendly driving state in a vehicle such as a vehicle or a hybrid vehicle, certain driving information detected is compared with a preset reference value, When the driving information is larger than the reference value, it is determined that the driving state is not friendly to the earth, and the driver is notified by an alarm or the like only when the driving state is not friendly to the earth.

[0006] Even when the detected driving information is less than the reference value and the driver does not receive a warning or the like, the driving condition is improved to further reduce fuel consumption and exhaust gas emission. In some cases, the operating state can be further optimized for the environment. However, the driver may erroneously recognize that the current driving state is an environmentally friendly driving state because the driver is not notified by an alarm or the like even though the driving state can be made more environmentally friendly. Thus, the current operation state is satisfied and the operation is continued.

[0007] As described above, even when driving a vehicle capable of reducing fuel consumption and exhaust gas emission compared to a conventional vehicle, the driver subjectively evaluates the driving state,
Or, in order to evaluate based on the evaluation result based on only a certain standard, even if the fuel consumption and exhaust gas emission can be further reduced, the operating state is not improved so that these are further reduced, This will reduce the commercial value of eco-friendly vehicles.

The present invention has been made in view of such a problem, and objectively evaluates a driving state and informs the driver of the evaluation result, whereby the driver can drive safely and is friendly to the global environment. It is an object of the present invention to provide a vehicle driving condition evaluation device capable of making the driving condition conscious.

And a differential device that allows and distributes.

The control means 6 includes a CPU, a RAM,
The microcomputer is provided with a microcomputer having a ROM or the like, and performs signal processing according to a preset program, so that, for example, the motor travels using only the motor generator 3 as a travel drive source, and travels using only the engine 1 as a travel drive source.

Do .

The control means 6 includes driving information necessary for switching the above-mentioned respective controls in accordance with the driving state, such as an accelerator pedal operation amount, a brake pedal operation amount, a vehicle speed, and the like.
Information on the acceleration / deceleration, the amount of power stored in the power storage device 7, the shift range of the shift lever, the inter-vehicle distance, and the like are input from various sensors (driving state detecting means).

Next, the operation of the hybrid vehicle thus configured will be described. First, the required driving force α is set according to the operation force or the operation amount of the accelerator pedal. The required driving force α is a predetermined value α1 (for example, the minimum value at which the operation force or operation amount of the accelerator pedal can be detected by a sensor)
In the following cases, it is determined that the vehicle is in the deceleration state, the motor generator 3 is caused to function as a generator, and the input shaft 4a of the transmission 4 is rotationally driven by the driving force (kinetic energy) from the driving wheels 8. The regenerative braking is performed to charge the electric storage device 7 with the electric energy generated by the above.

At the time of this regenerative braking, the clutch 2 is disengaged to disconnect the engine 1 from the drive wheels 8, so that the engine brake is disabled, and the engine 1 is driven by the drive force from the drive wheels 8. Without being forcedly rotated, the braking energy is more sufficiently recovered, and the fuel efficiency is improved. Further, at the time of this regenerative braking, the engine 1 is stopped, and the fuel consumption can be further improved because the engine 1 does not need to be idling.

In the case of regenerative braking in which the required driving force α is equal to or less than the predetermined value α1, the required braking force β set according to the operation force or operation amount of the brake pedal is changed to the predetermined value β1 (for example, the operation of the brake pedal). When the force or the operation amount is equal to or less than the minimum value that can be detected by the sensor, the braking by the braking force by the generator function of the motor generator 3, that is, the regenerative braking is performed. When the required braking force β exceeds a predetermined value β1 due to, for example, a depression operation of a brake pedal, the brake device 9 is actuated, and braking is performed by the braking force of the brake device 9 in addition to the braking force by regenerative braking. Done.

At the time of braking, the clutch 2 is disengaged in order to improve fuel efficiency, and the forced driving of the engine 1 is suppressed, so that the engine braking is not effective. At the time of braking, the clutch 2 may be connected to apply the engine brake.
Next, when the required driving force α becomes larger than the predetermined value α1,
The motor generator 3 functions as an electric motor, and the input shaft 4a of the transmission 4 is
Is driven to rotate, and motor running is performed using the motor generator 3 as a running drive source for the vehicle to regenerate drive wheels. Also during this motor running, the clutch 2 is disconnected and the engine 1 is stopped. When the amount of power stored in power storage device 7 is insufficient to perform regenerative driving, engine 1 is driven and clutch 2 is connected, and engine 1 is driven as a driving source without performing regenerative driving. Engine running.

Next, when the required driving force α becomes larger than a predetermined value α2 which is larger than the predetermined value α1, the engine 1 is driven and the clutch 2 is connected, and only the engine 1 is driven without performing the regenerative driving by the motor generator 3. Is driven by using the vehicle as a traveling drive source. The required driving force α is larger than a predetermined value α2 by a predetermined value α3.
When it becomes larger, the engine 1 is driven to connect the clutch 2 in the same manner as when the engine is running, and the engine 1 and the motor generator 3 are made to run by making the motor generator 3 function as an electric motor as in the case of the motor running. Engine / motor running driven as a drive source is performed.

When the depression amount of the accelerator pedal is kept constant and the vehicle is driven at a constant speed, the operation force of the accelerator pedal and the required driving force α based on the operation amount become a predetermined value α.
The range is larger than 1 and equal to or smaller than the predetermined value α2, and the motor running only by the regenerative drive by the motor generator 3 is performed. In this manner, the required driving force α is set in accordance with the operation force or the operation amount of the accelerator pedal, and in a range where the required driving force α is larger than the predetermined value α1 and equal to or less than the predetermined value α2, for example, in the range of the play of the accelerator pedal, the motor is driven. In the range where the required driving force α is larger than the predetermined value α2 and is equal to or smaller than the predetermined value α3, the engine is driven only by the engine 1 and is larger than the required driving force α3. In range, engine 1
And the regenerative drive by the motor generator 3 to drive the engine and motor. That is, as the required driving force α based on the operation force or the operation amount of the accelerator pedal increases, control is performed so as to sequentially shift to motor running, engine running, and engine / motor running.

When the required driving force α is equal to or less than a predetermined value α1, the motor generator 3 is used as a generator when the required driving force β set according to the operation force or the operation amount of the brake pedal is equal to or less than the predetermined value β1. Only the regenerative braking functioning to apply the braking force is performed, and in the range where the required braking force β is larger than the predetermined value β1, the brake braking in which the braking device 9 applies the braking force in addition to the regenerative braking is performed.

Next, a description will be given of a vehicle driving state evaluation system according to the present embodiment in which the driving control and the braking control are performed in accordance with the driving state. As shown in FIG. 2, the operating state evaluation system includes an operating state detecting means 10 for detecting an operating state, and a plurality of criteria set in advance corresponding to the operating information detected by the operating state detecting means 10. An evaluation criterion storage means 11 for storing values, and an operation state evaluation means 12 for comparing each operation information detected by the operation state detection means with a reference value of the evaluation criterion storage means to objectively evaluate the operation state.

First, the driving state detecting means 10 includes a vehicle speed sensor, a front / rear / lateral G sensor, an engine speed sensor, an inter-vehicle distance sensor, a throttle sensor, an accelerator pedal sensor, a brake pedal sensor, a steering wheel angle sensor, a battery sensor and the like. Each sensor is composed of various sensors, and relates to driving conditions such as vehicle speed, longitudinal acceleration, lateral acceleration, engine speed, inter-vehicle distance, throttle opening, accelerator pedal operation state, brake pedal operation state, steering wheel operation state, and the amount of stored power of the battery 7. Detects driving information.

The evaluation criterion storage means 11 stores a plurality of reference values which are set in advance corresponding to the respective pieces of driving information detected by the driving state detecting means 10. For example,
It is determined that the greater the acceleration / deceleration in the front-rear direction or the lateral direction, the higher the degree of danger, the lower the degree of gentleness to occupants, etc., and the lower the degree of gentleness to the environment due to poor fuel economy. In addition, a plurality of reference values relating to the front-rear or lateral acceleration / deceleration are set and stored in the storage means 11 so that the evaluation result becomes worse as the longitudinal / lateral acceleration / deceleration becomes larger.

The larger the amount of change in the operation of the accelerator pedal or brake pedal, the greater the vehicle behavior, the lower the degree of gentleness to the occupant, and the lower the degree of fuel economy and the degree of gentleness to the environment. A plurality of reference values relating to the operation change amount of the accelerator pedal and the brake pedal are set and stored in the storage means 11 for evaluating the operation result such that the larger the operation change amount of the accelerator pedal and the brake pedal is, the worse the evaluation result becomes. I have.

In order to judge that the higher the steering operation change amount and the higher the vehicle speed, the higher the degree of danger and the lower the degree of gentleness to the occupant, the worse the evaluation result. In addition, a plurality of reference values for the steering operation change amount and the vehicle speed are respectively set and stored in the storage means 11. In addition, in order to judge that the driving degree is higher as the inter-vehicle distance to a vehicle traveling in front or an obstacle is shorter than the safety distance according to the vehicle speed, and to evaluate the result such that the evaluation result becomes worse, the inter-vehicle distance is determined. A plurality of reference values relating to the inter-vehicle distance with respect to the safety distance according to the vehicle speed are set and stored in the storage means 11.

In addition, during steady-state running, the criteria regarding the vehicle speed fluctuation range are set so that the larger the vehicle speed fluctuation range, the lower the fuel efficiency and the lower the degree of environmental friendliness. A plurality of values are set and stored in the storage unit 11. in this way,
The criterion storage means 11 stores a plurality of reference values corresponding to the driving information detected by the driving state detecting means 10 for each driving information.

The operation state evaluation means 12 compares each operation information detected by the operation state detection means 10 with each reference value stored in the evaluation reference storage means 11 corresponding to the operation information. The driving state based on the information is evaluated, and the evaluation results of the driving state based on the respective driving information are integrated to objectively evaluate the driving state of the vehicle. This operation state evaluation means 1
The method of evaluating the operating state in 2 will be described. As this evaluation method, the driving state evaluation means 12 performs driving with respect to the degree of safe driving, the degree of gentleness to occupants / pedestrians, and the degree of gentleness to the environment (degree of influence on the environment) as shown in FIGS. Evaluate the condition.

First, in the evaluation of the degree of safe driving, as shown in FIG. 3, evaluation items such as degree of acceleration / deceleration, degree of turning and running, degree of wheel slip, degree of assist function operation, degree of inter-vehicle distance, and degree of compliance with traffic rules are evaluated. I do. In the acceleration / deceleration evaluation item, the acceleration in the vehicle longitudinal direction detected by the longitudinal G sensor is determined by a plurality of reference values stored in the determination reference storage unit 11 corresponding to the acceleration, for example, predetermined values a1, a
As compared with 2, a3, etc., in the case of a rapid acceleration operation or a rapid deceleration operation in which this acceleration is equal to or more than a predetermined value a1, a deduction point 2, and an acceleration in which the acceleration is smaller than the predetermined value a1 and equal to or more than a predetermined value a2 When driving or decelerating, deduction point 1
Evaluation point 0 when the acceleration operation or the deceleration operation is performed such that the acceleration is smaller than the predetermined value a2 and is equal to or more than the predetermined value a3, and the point is added when the acceleration operation or the deceleration operation is performed so that the acceleration becomes smaller than the predetermined value a3. As set to 2,
It is determined that the greater the degree of acceleration / deceleration, the more dangerous the driving state, and the higher the acceleration in the front / rear direction, the lower the evaluation point is.

In the evaluation of the degree of acceleration / deceleration, the degree of change in the operation amount of the accelerator pedal detected by the accelerator pedal sensor is also evaluated. In other words, it is determined that the greater the speed of change of the operation amount of the accelerator pedal, the greater the behavior of the vehicle is, and the more danger is involved. Based on a plurality of reference values corresponding to the speed of change of the accelerator pedal, as in the evaluation method based on acceleration, The evaluation point is determined between +1 and -2 according to the change speed so that the higher the change speed of the operation amount, the lower the evaluation point.

In the turning traveling degree, it is determined that the turning state becomes unstable and dangerous as the lateral acceleration increases, and the lateral acceleration detected by the lateral G sensor is determined based on a plurality of reference values corresponding to the lateral acceleration. The evaluation point is determined between +1 and -2 according to the lateral acceleration so that the evaluation point is lower as the value is larger. In addition, it is determined that the turning state becomes unstable and dangerous as the change amount of the steering wheel operation angle increases, and the change of the steering wheel operation angle detected by the steering wheel angle sensor is determined based on a plurality of reference values corresponding to the change amount. The evaluation point is determined between +1 and -1 according to the amount of change in the steering wheel operation angle so that the larger the amount, the lower the evaluation point.

The degree of wheel slip is evaluated based on the amount of slip of each wheel detected by the wheel speed sensor. If any one of the wheels generates a slip, it is evaluated to be deducted. It is determined that the larger the amount of occurrence is, the more dangerous it is, and based on a plurality of reference values respectively corresponding to the period and amount of occurrence of the slip, the evaluation score becomes lower as the period of occurrence of slip or the amount of occurrence of slip is larger. The evaluation point is determined between +1 and -2 according to the slip occurrence period or the slip amount.

The degree of operation of the auxiliary function depends on the ABS device and TC.
The evaluation is based on the operating states of auxiliary devices such as L (traction control) devices and left and right wheel driving force distribution adjusting devices. It is determined that the longer the operating time or the more frequently the auxiliary devices are operated, the more dangerous it is. Therefore, based on a plurality of reference values respectively corresponding to the operation time and the operation frequency,
The evaluation point is determined between +1 and -2 according to the operation time or the operation frequency such that the evaluation point becomes lower as the operation time or the operation frequency of the auxiliary device is larger.

The vehicle-to-vehicle distance is evaluated based on the vehicle-to-vehicle distance with respect to a preceding vehicle or an obstacle detected by the vehicle-to-vehicle distance sensor, and the vehicle-to-vehicle distance is determined based on a plurality of reference values corresponding to the vehicle-to-vehicle distance. When the distance between vehicles is less than the safe inter-vehicle distance, it is judged to be dangerous and the evaluation score is lowered so that the vehicle is judged to be safe and the evaluation point is added when the distance is longer than the safe inter-vehicle distance according to the vehicle speed. The evaluation point is determined between +1 and -3 according to the following distance.

In the degree of compliance with traffic rules, information on traffic rules, such as road signs and signals, is photographed by a camera or the like, and the photographed image is subjected to image recognition processing to discriminate the road signs, signals, and the like. This is to determine and evaluate whether or not to comply with traffic rules such as road signs and signals. When these traffic rules are complied with, it is judged to be safe and the evaluation point is set to zero without deduction or addition, and each time a traffic rule is violated, points are deducted based on multiple reference values corresponding to the traffic rules. To evaluate. If the content of the violation is remarkable or the violation state is continued, the evaluation points are determined so that the points are greatly deducted. The road sign or the like may be determined based on information from the navigation system.

Next, in the evaluation of the degree of kindness with respect to the occupant / pedestrian, as shown in FIG. 4, the degree of acceleration / deceleration, the degree of turning, and the degree of pedestrian protection are evaluated. In the evaluation of the degree of gentleness to the occupant / pedestrian, in the evaluation of the degree of acceleration / deceleration, as the acceleration / deceleration in the front-rear direction and the changing speed of the accelerator operation amount increase, and in the evaluation of the degree of turning travel, the lateral acceleration and steering wheel operation angle are evaluated. The greater the change in
Judging that the driving is not friendly to the occupant, the variable acceleration, the changing speed of the accelerator operation amount, and the lateral acceleration are evaluated in the same manner as the evaluation method of the acceleration / deceleration degree and the turning degree in the evaluation of the safe driving degree. Based on a plurality of reference values respectively corresponding to the change amount of the steering wheel operation angle, the evaluation point is set to be lower as the acceleration / deceleration, the change speed of the accelerator operation amount, the lateral acceleration, and the change amount of the steering wheel operation angle are larger. You. In the present embodiment, the evaluation points of the degree of acceleration / deceleration and the degree of turning traveling in the evaluation of the degree of kindness with respect to the occupant / pedestrian are set to be the same as the evaluation points of the degree of safe driving, but set differently. May be.

The pedestrian protection degree is detected by the inter-vehicle distance sensor when a pedestrian is detected by infrared rays or an image captured by a camera, although the driver is alerted by the display device 13 or the voice alarm device 14. If the inter-vehicle distance to the pedestrian is shorter than the safe inter-vehicle distance according to the vehicle speed, it is determined that protection of the pedestrian is insufficient, and the evaluation point is determined based on a plurality of reference values corresponding to the inter-vehicle distance. The vehicle speed is determined between +1 and -2 so that the lower the inter-vehicle distance to the driver, the shorter the inter-vehicle distance according to the vehicle speed.

Next, in the evaluation of the degree of environmental friendliness, as shown in FIG. 5, the degree of acceleration / deceleration, the degree of steady running, the degree of motor running, the degree of exhaust gas emission, and the like are evaluated. The degree of acceleration / deceleration in the evaluation of the degree of environmental friendliness is such that the larger the acceleration / deceleration or the rate of change of the accelerator operation amount is, the less environmentally friendly the driving state is. As with the evaluation method of the acceleration / deceleration rate in the evaluation of the degree,
Based on a plurality of reference values respectively corresponding to the acceleration / deceleration and the change speed of the accelerator operation amount, the change speed of the accelerator operation amount is determined between +1 and -2 so that the larger the acceleration / deceleration, the lower the evaluation point becomes. Is determined between +1 and -1 such that the larger the is, the lower the evaluation point is. In the present embodiment, the evaluation points of the degree of acceleration / deceleration in the evaluation of the degree of gentleness to the environment are set to be the same as the evaluation points of the degree of safe driving and the degree of gentleness to the occupant / pedestrian. May be set.

In the high-speed running degree, it is determined that the higher the speed, the lower the fuel efficiency and the environment is not friendly, and based on a plurality of reference values corresponding to the vehicle speed, if the vehicle speed is higher than a predetermined value, the vehicle speed becomes higher. A value between +1 and -3 is determined according to the vehicle speed so that the larger the score is, the lower the evaluation point is. When the vehicle speed fluctuation range is within a predetermined range, it is determined that the vehicle speed fluctuation is less wasteful acceleration and deceleration and the fuel efficiency is good, and that the larger the vehicle speed fluctuation width, the worse the fuel efficiency and the environment is not friendly to the environment. Based on multiple reference values corresponding to the fluctuation range,
The larger the vehicle speed fluctuation range, the lower the evaluation score.
It is determined between 1 and -2.

In the vehicle driven by the driving force of at least one of the driving force from the engine 1 and the driving force from the motor generator 3, the driving by the motor driving using only the motor generator 3 as the driving source is performed. The longer the time, the lower the fuel consumption, the lower the exhaust gas emissions, and we judge that the operation is environmentally friendly.
Based on a plurality of reference values corresponding to the motor running time,
The evaluation point is determined between +2 and -1 so that the point is increased as the motor running time is longer and the point is reduced as the motor traveling time is shorter.

With respect to the degree of energy regeneration, an operation state in which the regenerative braking rate is high, for example, a slow deceleration state, is determined to be environmentally friendly operation, and an operation state in which the regenerative braking rate is poor, for example, a rapid deceleration state, is considered to be environment-friendly operation. Based on the plurality of reference values corresponding to the deceleration, the evaluation points are determined between +1 and -1 such that the larger the deceleration, the more the evaluation points are deducted.

With respect to the degree of exhaust gas emission, it is determined that the operation is more unfriendly to the environment as the amount of exhaust gas is increased, and based on a plurality of reference values corresponding to the amount of exhaust gas, the evaluation point becomes lower as the amount of exhaust gas is increased. It is determined between +2 and -3. The exhaust gas emission amount is obtained by multiplying a previously stored emission concentration in the entire operation range and operation mode by an exhaust gas amount calculated from an intake air amount, and further purifying the exhaust gas concentration by a catalyst O2 sensor, a catalyst temperature sensor, or the like. It is obtained by multiplying the efficiency and calculating the emission amount (discharge amount) for each fixed time. Then, based on the emission amount per traveling distance and the integrated emission amount corresponding to the traveling vehicle speed obtained from the emission amount at regular time intervals, the evaluation points are deducted from +2 to −3 as the emission amount increases. Decided between.

The method for calculating the exhaust gas emission is not limited to this. In addition, the amount of exhaust gas emitted is CO ₂
Although the concentration and the NOx concentration are integrated, the evaluation may be performed only by the CO ₂ concentration and the NOx concentration.
FIG. 6 shows a summary of the evaluation methods in the main driving information among such evaluation methods in one evaluation map. This evaluation map shows evaluation criteria from the start to the stop until the acceleration at the start is larger than the two-dot chain line L1 shown in FIG. A rapid acceleration state is determined also between L1 and the dash-dot line L2, a normal acceleration state is determined between the dash-dot line L2 and the solid line L3, and a slow acceleration state is determined when the difference is smaller than the solid line L3. Are evaluated as -2, -1, 0, +1. Also, if the vehicle speed fluctuation range during normal running is within the range indicated by the dotted lines L4 and L5, +
2. In a case where the range greatly exceeds the range of the dotted lines L4 and L5 (for example, it is equal to or more than a predetermined amount), the evaluation point is determined to be -1. At the time of deceleration, if the deceleration is equal to or smaller than the solid line L6, it is determined to be a slow deceleration state, and if the deceleration is equal to or more than the one-dot chain line L7, it is set to a rapid deceleration state. Judgment is made, and −1 and an evaluation point are determined. When the motor running state is long as shown by a broken line L8 (for example, longer than a predetermined time), the evaluation point is +2.
It is said.

The method for determining the evaluation points is not limited to the above-described example. In addition, the above-described evaluation points and the reference values stored in the determination criterion storage unit 11 are changed according to a driving condition or a driving condition based on the driving information detected by the driving condition detection unit 10. It is recommended that each driving situation and driving situation be evaluated appropriately. For example, a coefficient may be added to a reference value or an evaluation point according to the situation so that the evaluation result when traveling on an uphill road or a congested road where acceleration / deceleration is large is evaluated as equivalent to when traveling on a straight road. It may be evaluated by multiplying.

Based on such an evaluation method, the driving state evaluation means 12 determines the safe driving degree and the kindness degree for the occupant / pedestrian from each driving information such as the vehicle speed and acceleration detected by the driving state detection means 10. The degree of environmental friendliness is evaluated based on evaluation points determined for each evaluation item such as the degree of acceleration / deceleration and the degree of motor travel. That is, the driving information detected by the driving state detecting means 10 is compared with the reference value for each driving information stored in the evaluation criterion storage means 11 to determine an evaluation point for each driving information. The evaluation points are calculated for each evaluation item from the evaluation points, and the evaluation points of each evaluation item are integrated to objectively determine the driving state objectively with respect to the degree of safe driving, the degree of gentleness to occupants / pedestrians, and the degree of environmental friendliness. evaluate. Furthermore, the driving state of the vehicle is objectively evaluated by integrating the evaluation results of the degree of safe driving, the degree of gentleness to occupants / pedestrians, and the degree of gentleness to the environment.

The evaluation points in the respective driving information in the above evaluation items are stored in the evaluation criterion storage means 11 in the operating state detecting means 1.
It is determined by comparing a plurality of reference values respectively set corresponding to each piece of driving information detected by 0 with driving information from the driving state detecting means 10. For example, a reference value of acceleration / deceleration in the front-rear direction for determining a slow acceleration / deceleration state in which the evaluation point is +1 or a rapid acceleration / deceleration state in which the evaluation point is −2 in the evaluation of acceleration / deceleration, for example, slow acceleration A plurality of reference values such as a predetermined value a1 for determining a state (acceleration a <a1) and a predetermined value b1 for determining a rapid deceleration state (deceleration> b1) are stored in the storage unit 11. The reference value regarding the acceleration and the acceleration / deceleration from the operating state detection means are compared, and the evaluation result is determined based on the comparison result.

The operating state evaluation means 12 determines the operating state based on the operating information detected by the operating state detecting means 10 based on the reference value of the evaluation reference storage means 11, and determines the operating state based on the determination result. Although comprehensive evaluation is performed objectively, this evaluation method includes a method of evaluating an instantaneous driving state and a method of evaluating a long-term driving state.

As a method for evaluating the instantaneous operating state, every time updated operating information is input from the operating state detecting means 10, the instantaneous operating state is evaluated based on the operating information. Further, as a method of evaluating a long-term driving state, there is a method of comprehensively and objectively evaluating a driving state during a predetermined period from an engine start to a stop or from a stopped state of a vehicle to a stop after restarting. , The result of the instantaneous operation state evaluation is integrated. For example, the instantaneous driving state based on the driving information from the driving state detecting means 10 is evaluated by the evaluation point for each evaluation item,
The instantaneous operating state is comprehensively evaluated based on the evaluation points, and the long-term operating state is determined based on the total evaluation points of the respective evaluation items obtained by integrating the evaluation points of the respective evaluation items of the instantaneous operating state for a predetermined period. To evaluate.

The accumulation evaluation result accumulated in the accumulation unit 15 can be arbitrarily displayed on the screen of the display device 13 by operating an operation unit (not shown) of the display device 13. You can check if it was something like that.

Accordingly, it is possible to investigate the evaluation results of the driving state up to now, and it is also possible to determine whether the driver is a good driver or a poor driver based on the accumulated evaluation results. It should be noted that the evaluation result stored in the storage means 15 is not erased unless a battery power is removed or a specific operation such as an erase operation by an external device is performed.

The driving instruction means 16 includes the driving state detecting means 1
This is to advise the driver on how to perform the driving operation so that the driving state detected at 0 is a good driving state in terms of environment, safety, and the like. The driving instruction means 16 stores a specific operating state set in advance and driving instruction information for the specific operating state. Then, the driving information detected by the driving state detecting means 10 is input, and it is determined whether or not the driving state based on the detected driving information corresponds to a specific driving state. When the judgment is made, the driving guidance information for the specific driving state is displayed on the display device 13 and the voice alarm device 14 is caused to warn the driver to contact the driver. Here, the specific operating state is an operating state that is inferior in terms of, for example, the environment and safety and requires improvement.

On the display screen of the display device 13, driving guidance information for the specific operation state is displayed. For example, when a rapid acceleration operation or a rapid deceleration operation set to the specific operation state is performed, Instructions such as "Let's accelerate a little more smoothly!" And "A little earlier braking!" Are displayed. Contact

In addition, if the inter-vehicle distance is shorter than the safe inter-vehicle distance in accordance with the vehicle speed, "the inter-vehicle distance is reduced by one more.
Let's take enough 0 meters! Is displayed, or if the vehicle is in a sharp turn, if it is determined that the driving state is dangerous, such as "Let's slow down enough before the curve!", The dangerous state can be avoided. To inform us of important driving guidance information.

If it is determined that the driving state is not friendly to the environment or the occupants, for example, if the driving state is one in which acceleration and deceleration are frequently repeated, the message "another vehicle + If you read the traffic light, you will be notified of driving guidance information that will be gentle to the environment and occupants. The voice alarm device 14 also notifies the driver of the same driving guidance information for the corresponding specific driving state by voice. It should be noted that the communication of the driving guidance information by the voice alarm device 14 is such that the driving state is remarkably inferior in a particular driving state in terms of environment, safety, and the like.
The setting is made so that the operation is performed only when the operation state requires immediate improvement.

The driving instruction information is displayed on the screen of the display device 13 for a certain period of time. However, when the driver understands the driving instruction information displayed on the screen or warned by the voice alarm device, the driving instruction information is displayed. Indicates the “O” displayed on the screen.
When the driver touches the item "K", the driving guidance information displayed on the screen is erased, and the warning about the guidance information by the voice alarm device is not performed.

As described above, the evaluation result evaluated by the driving state evaluation means 12 and the driving guidance information by the driving guidance means 16 are displayed on the display device 13 and the voice alarm device 14.
The driver will be contacted by voice, but depending on the driver, they may not be satisfied with these evaluation results and driving guidance information and may have questions or want to know more detailed information There are cases. In such a case, when the driver touches the “detailed information” item portion on the display screen on which the evaluation result and the driving instruction information are displayed, detailed information on the evaluation result and the driving instruction information are displayed. You.
Therefore, drivers who are unsatisfied with the evaluation results and driving guidance information and have questions or want to know more detailed information should understand the evaluation results and driving guidance information with this detailed information. It is possible to recognize how to drive in the future driving, and to perform driving that is in a good operating state in terms of environment and safety.

It is sometimes troublesome to notify the driver of the evaluation result of the driving state and the driving guidance information by the display of the display device 13 or the voice of the voice alarm device 14, depending on the driver and the driving condition. . In some cases, it may be better to set different evaluation criteria for determining whether or not the vehicle is in a good driving condition in terms of environment and safety, depending on the skill of the driving operation technique. In such a case, when the driver touches the “setting change” item portion on the display screen of the display device 13, the reference value stored in the determination reference storage unit 11 and the display determination of the instantaneous evaluation result are determined. The level, the alarm determination level of the alarm device 14, the display content of the display screen of the display device 13, and the like are arbitrarily changed according to the driver, and the display of the evaluation result and the warning on the display device 13 and the warning by the alarm device 14 are performed. It is configured to be able to stop.

For example, a driver who thinks that the screen display and the voice warning are very troublesome can increase the display and voice warning determination levels beyond the general determination level, thereby displaying the evaluation result and the driving guidance information screen display and voice warning. Can be reduced in frequency. Further, it is also possible to make only the alert by only the screen display. As described above, the vehicle driving state evaluation device according to the present embodiment stores the driving information relating to the driving state detected by the driving state detection unit 10 into a plurality of corresponding reference values stored in the evaluation reference storage unit. The evaluation points are determined for each piece of driving information so that the driving state based on each piece of driving information is objectively evaluated as compared with. Then, the driving state is evaluated for each preset evaluation item based on the driving state evaluation result based on each driving information, and the evaluation result of each evaluation item is integrated to determine the driving state of the vehicle as a safe driving degree. And the degree of kindness to passengers and pedestrians and to the environment. Furthermore, the driving state of the vehicle is objectively evaluated by integrating these evaluation results. These evaluation results are displayed to the driver on the display device 13 or the voice alarm device 1.

As described above, the driving information relating to the driving state is objectively evaluated based on a plurality of reference values, and based on the evaluation result based on the driving information, the degree of good driving state (for example, the evaluation score in the above embodiment). The overall evaluation result is objective, and the objective evaluation result, that is, the degree of the objective driving state, is communicated to the driver. Can subjectively evaluate the driving state without subjectively evaluating the driving state.

Therefore, the driver is not satisfied with the subjective evaluation result, and the driver is not contacted only when the driving state is evaluated based on only a certain standard and the evaluation result is not good. If the evaluation result is good according to the objective evaluation result, for example, if the evaluation point in the embodiment is evaluated to be high and the good degree of the driving state is high, the driving state is continued and the evaluation result is In the bad case, for example, when the evaluation point in the embodiment is evaluated as low and the good degree of the driving state is evaluated to be low, the driver will be conscious of the driving state such that the objective evaluation result is improved, and as a whole, The driving condition of the vehicle is improved.

The operating state is determined by the operating state detecting means 10.
Is evaluated based on an evaluation point determined by comparison with the reference value of the driving information detected by the above. An evaluation point is determined by adding when the driving state is good and subtracting when the driving state is bad. Therefore, it is possible to comprehensively evaluate the degree of good operating conditions, that is, the good and bad operating conditions.

Further, the vehicle driving condition evaluation apparatus according to the present embodiment objectively comprehensively evaluates the goodness of the long-term driving condition and the instantaneous driving condition, and obtains the respective evaluation results in both driving conditions. Since the driver is notified, the driver can recognize the objective evaluation results in the long-term driving state and the instantaneous driving state.

Therefore, the driver can recognize what the driving state is due to the driver's own driving operation by objective evaluation of the long-term driving state and the instantaneous driving state. Motivation to try to drive more appropriately. In addition, such a driving state evaluation makes the driving operation itself feel like a game, and provides the driver with new driving pleasure.

Further, since the result of the evaluation of the instantaneous driving state is reported to the driver each time, the driver instantly recognizes the instantaneous driving state objectively as to what the driving state is. And the operating condition in the future can be improved. In addition, in the evaluation device according to the present embodiment, the evaluation is performed for each evaluation item based on the evaluation result of the driving information by the driving state detection unit 10, and the degree of influence on the environment and the safe driving Because the evaluation of the degree of good driving condition is evaluated, the driver can recognize the driving condition in terms of safety and environment from the evaluation result in terms of safety and environment, and also, in terms of safety and environment, The driver is consciously driven to be in a good driving state, and the vehicle society as a whole is changing in a positive direction in terms of safety and environment.

In the evaluation device according to the present embodiment,
The evaluation results are stored and stored in the storage device, and the stored evaluation results are displayed so that the investigation can be performed. Therefore, whether the driver is superior to the evaluation results stored in the storage means. Alternatively, it is possible to quickly and accurately determine whether the driver is a poor driver. If it becomes possible to determine the driver from the accumulated evaluation results in this way, for example, a public organization or an automobile manufacturer will commend a good driver, or a public organization will warn a bad driver. When such a system is issued, by examining the accumulated evaluation results, it is possible to accurately determine a good driver or a bad driver. In this way, if a system is given, such as to commend a good driver based on the accumulated evaluation results or to issue a warning to a bad driver, the driver will be an excellent driver. As a whole, the driving society will change in a better direction in terms of environment and safety, etc.

Further, the evaluation device according to the present embodiment communicates driving guidance information to the driver through the display device 13 and the voice alarm device 14 when the driving state is notably unfavorable in terms of environment and safety. Not only recognize the evaluation result of what kind of driving state it is, but also how to operate it and what kind of driving operation is good driving from the environmental and safety aspects. The driver can be recognized, and the driver can perform good driving in terms of environment and safety by driving guidance, and in the subsequent driving operation, it is significantly better in the same environment and safety. It is difficult for the driver to drive the car, and the car society as a whole is changing in a positive direction in terms of environment and safety.
