FIG. 1 is a block diagram showing a first embodiment of the present invention. In FIG. 1, reference numerals 1a to 1e denote a vehicle speed sensor, an acceleration sensor, a throttle opening sensor, a steering sensor, and a brake sensor, respectively. Each of these sensors is installed at each part of the vehicle (not shown) and takes data. 2 performs an operation based on information from the various sensors 1a to 1e and data from the storage means,
CPU (Central Processing Unit), 3 is a timing unit, 4 is a first storage unit for accumulating and storing a vehicle operation state for each driver of the vehicle from the various sensors, 5 is a driver of the vehicle, various warnings Second storage means for storing the message,
Reference numeral 6 denotes input means for the driver to input data, 7 denotes display means for performing various displays, and 8 denotes sound emitting means. The data detected by each of the sensors 1a-1e is sent to the CPU 2, and the CPU 2 takes into account the sent data and the time of the time measuring means 3 and corresponds to the driver stored in the second storage means 5. When the vehicle operation state that is significantly different from the vehicle operation state continues for a predetermined period of time or is repeated for a predetermined period of time compared with the past vehicle operation state stored in the first storage unit 4, the driver is warned by the sound emitting unit 8. In addition, the display unit 7 indicates a difference in the vehicle operation state and warns the user. Further, when the vehicle operation state is in a range not different from the past, the data is stored in the first storage means 4 when the storage mode is set, and is discarded otherwise. This mode can be appropriately selected by the driver from the input means 6. The first storage means 4 stores, for example, comparison data between the speed and the steering angle as shown in FIG. 2, and indicates whether or not there is a traveling state based on the traveling state in a storage mode described later (Yes = 1). , Nothing = 0). In addition, various comparison data such as vehicle speed versus brake pedaling force (not shown), acceleration versus throttle opening, and throttle operation to brake operation intervals are also stored for each driver, for the general road mode and for the highway mode. . Further, as shown in FIG. 3, the second storage means 5 stores correspondence information for each mode between the driver identifier and the comparison data stored in the first storage means, excessive speed, excessive steering, etc. C
Various message data for notifying according to the PU determination state are stored in advance.

Next, the operation and operation of the present embodiment (hereinafter referred to as the present machine) will be described in detail. First, as an initial operation, when the driver X is in a normal running state (running on a known road with no particular fatigue, etc.) at a time when he / she is sufficiently used to the vehicle on which the vehicle is mounted, input means is provided. The driver inputs that it is X from 6 and then puts the machine in the storage mode. In this state, the vehicle travels for a certain period (distance) to accumulate the standard traveling state, that is, various driving operation states. If an operation in an unusual state such as sudden braking is unavoidably performed during this period, a reset operation is performed by the input means 6 and the operation is repeated. This initial operation is performed for each individual when a plurality of drivers are present, thereby accumulating various operating conditions corresponding to the individual driving operations.

At the end of the storage mode, after a normal running for a certain period, the operation mode is changed to the operation mode by the input means 6.
The identification of the driver in this operation mode may be performed by the input means 6 or, as is generally performed, the key of the vehicle is provided with an identifier for each driver and automatically identified from the key. You may do it.

The operation state in the operation mode will be described below with reference to the flowcharts of FIGS.

First, when the vehicle is started in the operation mode, in step 1, each sensor starts detection. Step 2
It is checked from the information of the speed sensor 1a and the timekeeping means 3 whether the high-speed traveling at, for example, 80 km / h or more is continued for a predetermined period (or whether the traveling state is similar to the traveling state on the highway traveling in the initial storage mode), If this condition is satisfied, the process proceeds to step 3 where the vehicle is regarded as traveling on the expressway and the mode is shifted to the expressway traveling mode. If this condition is not satisfied, the process proceeds to step 4 and shifts to the general driving mode. Next, when the vehicle enters the general driving mode, it is determined in step 10 that the speed is excessive based on the speed information. If the speed is out of the speed range stored in the first storage means 4, the process proceeds to step 11 and counts up. Then, in step 12, it is determined whether or not the counted number has exceeded the limit value within a predetermined period. If not, the process returns to step 10;
Proceeding to 3, the corresponding warning display previously stored in the second storage means 5, that is, a message "speed is too high than usual" is displayed on the display means 7, and the sound emission means 8 simultaneously notifies. . If there is no excess speed, the process waits until various operations are performed via step 14 while always checking for excess speed. Thus, for example, if a steering operation has been performed, the process proceeds to step 15 and step 1
In step 6, the relationship between the speed and the steering is checked based on the information from the sensor, and the relationship between the speed and the steering stored in the first storage means 4 is compared with the relationship between the speed and the steering.
Return to step 1, but if it is determined that the
In step 18, it is determined whether or not the counted number has exceeded the limit value within a predetermined period. If not, the process returns to step 11.
, The corresponding warning display, which is stored in advance in the storage means 5, that is, “The steering operation is too fast than usual.”
A message such as "The steering wheel operation is too much for the speed" is displayed on the display means 7 and the sound emission means 8 notifies at the same time. When the brake operation is performed, the operation enters the brake operation mode in step 20, and in step 21, the relationship between the strength and the speed of the brake operation is compared with data (not shown) in the first storage means to deviate from a predetermined range. If not, the process returns to step 11, but if it is determined that the value has deviated, the count is incremented in step 22 and step 2
In step 3, it is determined whether or not the counted number has exceeded the limit value within a predetermined period. If not, the process returns to step 11, but if not, the corresponding value stored in the second storage means 5 in advance. Warning means, that is, a message such as "Brake operation is too strong for speed" or "Brake operation is too much for speed" is displayed on display means 7.
At the same time, and at the same time, the sound emitting means 8 notifies. Further, when the throttle operation is performed, step 25 is performed in the same manner as described above.
As shown in steps 29 to 29, the throttle operation amount and the steering amount are compared and a corresponding message is displayed.

Although not shown, the "acceleration status"
And "throttle opening", "acceleration (deceleration) status" and "brake operation status", or "acceleration (deceleration) status", "brake operation status" and "steering operation status", etc. In contrast to the data (not shown) in the storage means, if it deviates from the predetermined range, it is notified. In the highway mode, the data for the highway stored in the first storage means ( (Not shown) and performs the same operation.

The concept of this embodiment is shown in the valve diagram of FIG. That is, assuming that the range of A is the entire driving operation of the vehicle and the range of B is a range that can be regarded as not dangerous, the range of A∩B becomes a dangerous driving operation. Next, when the range of the normal driving operation of a person is the range of C,
In this embodiment, A is a dangerous driving operation
に 対 し て Not only for the driving operation in the range of the bar B, but also in the driving operation at the point C ', that is, the driving operation in the range of the bar な い C which is not a dangerous dangerous operation, but is a normal driving specific to an individual It is possible to warn the driver of some sort of driving operation outside the operation range. In addition, the range of dangerous driving operation is generally set to be narrower in consideration of individual differences. The range of B can be set relatively wide because there is a range of C, which is the range of normal driving operation of a specific person, and the range of A∩bar B is the range of truly dangerous driving operation. There is no need to be notified frequently and troublesome.

As a criterion for each judgment processing in the above embodiment, data can be obtained by assuming the following states, and the data can be applied to the program as a criterion.

For example, when the vehicle is driven in a state of falling asleep, the correction of the course during traveling is delayed, and therefore, the steering with a larger steering angle is performed more rapidly than usual. In addition, when driving on a road with many danger factors, sudden braking is frequently performed more frequently than usual. Even in an unpleasant state, various operations lack certainty or become rough. Further, in such a case, the throttle operation is often different from the usual operation. That is, even if the brake is not applied, the throttle is frequently decelerated so that the foot is released from the throttle pedal. In addition, it can be determined that, for example, traveling that frequently repeats stopping → high speed traveling → stopping is different from normal traveling from the traffic environment. Further, by applying a well-known fuzzy inference to each determination process, a more advanced determination process can be performed. Therefore, for example, the brake operation or steering operation that is harder than usual for a certain period of time due to falling of the reflex operation without falling asleep or subjective symptoms, or running on a road that is not accustomed to running, running on a road with many dangerous factors, etc. If a running pattern different from the normal one is performed, a warning is displayed on the display unit or a sound is emitted,
At least, it is objectively shown that one's driving is different from the usual driving, so that it is possible to take measures such as taking a rest or driving with more caution.

In the above-described embodiment, the vehicle state and operation data are obtained by the various sensors described above. However, regardless of this, information such as a gear change operation, a horn operation, and a light lighting operation is used. It is needless to say that the determination may be made based on the information from the sensors, and it is more preferable that the information from the sensors is processed in a comprehensive manner instead of the one-to-one determination. In the above embodiment, an example in which the present invention is applied to driving of a vehicle is disclosed. However, the present invention may be applied to other machines driven by humans. In such a case, the above-mentioned sensor may be made suitable for the machine, and data may be appropriately determined.
