It is possible to recognize driving advice and the like without mounting the device at a position where the driver can see.

FIG. 2 is a block diagram showing an example of the basic configuration of the apparatus according to the present invention.
At the same time, the acceleration sensor 21 (single or plural) is connected to the input and output of each element shown in FIG. The acceleration sensor 21 used as the vehicle acceleration measuring means is for measuring acceleration including at least the front-rear direction, the left-right direction, or both directions, and detects the acceleration in a predetermined direction using the law of inertia. Or a piezoresistive acceleration sensor or the like is applied.
Connected to or built in Central processing unit (CP
U) 20, a storage device 22 is built in or connected thereto, and together with an operation program, input data, measurement data,
Data such as a calculation result is stored. In the game device with the driving skill evaluation function according to the present invention, the data from the acceleration sensor 21 is analyzed from both the amplitude and the frequency by the operation program, and the game progress and the driving skill evaluation are performed.

In such a configuration, a method for evaluating driving skill according to the present invention will be described in detail. In the present invention, the magnitude of acceleration in the front-rear direction or the left-right direction, etc., which is obtained as a result of driving a vehicle such as an automobile, a bicycle, and a two-wheeled vehicle, is measured. Recognizing the frequency, evaluating driving skills (skills of driving technology, etc.), estimating road conditions, and displaying driving result evaluations and advice based on the results, and simultaneously inputting the contents of the input data into the game progress It is used as an input parameter, and the driving situation and the driving result are used as main elements of the game development. The evaluation of the driving skill is performed based on the detection data of the amplitude and the frequency of the acceleration included in the measurement data of the acceleration.

The objects to be evaluated are mainly the safe driving and the dangerous driving of the driver. Based on the above detected data, the magnitude and frequency of changes in acceleration, deceleration, and traveling direction related to the traveling of the vehicle are determined. Recognize, determine the degree of safe driving of the driver based on the recognition result, and evaluate the driving skill by determining the degree of dangerous driving (driving to be suppressed including violent driving) for each element. Like that. Dangerous driving factors include sudden acceleration, sudden braking, sudden steering, meandering driving, etc. If these dangerous driving are recognized,
The alarm message corresponding to the element is displayed on the display unit 11,
The information is output to the audio unit 14 or the like, and is notified to the driver including an audio warning.

I try to evaluate my skills. For example,
The magnitude and frequency of the acceleration in the front-back direction are analyzed by a predetermined algorithm, and whether the acceleration / deceleration in the front-back direction is repeated due to repeated starting and stopping due to traffic congestion or due to rough driving (sudden starting, sudden braking, etc.). In the former case, it is presumed that it is due to road conditions, and in the latter case, it is presumed that the accelerator operation or the brake operation is rough, and the driving skill is evaluated according to these estimation results.

Further, the magnitude and frequency of the change in the traveling direction in the left-right direction are analyzed by a predetermined algorithm, and it is determined whether the repetition of the left-right acceleration is due to a road curve or a meandering operation. If so, it is estimated that it is due to road conditions, and if the latter, it is further estimated whether there is a possibility of drowsy driving or violent driving based on the magnitude of the acceleration and the occurrence interval. In the latter case,
In this example, a warning to the driver is displayed by voice or the like in accordance with the estimation result, thereby preventing an accident. By providing a sensor for detecting the acceleration in the vertical direction, the roughness of the road surface may be determined, and the acceleration in the three-dimensional direction may be measured and displayed.

The driving advice function by voice is a function of displaying various advices in voice according to the driving state of the vehicle (running state and driving skill evaluation result). For example, if the running time exceeds a predetermined time, the user is prompted to take a break (2
When the time is exceeded, "Tired, rest!" Etc. is displayed in text and voice to advise the driver. In addition, at the time of sudden braking or sudden start / stop, depending on the degree of danger ("Driving now is dangerous! Be careful",
"Kiken! Let's run more gently" is displayed in text and voice to advise the driver.

The fuel efficiency check function is a function of displaying the current fuel efficiency (distance per liter), the total distance traveled, the average fuel efficiency, and the oil change from the input travel distance and refueling amount. In the oil change display, for example, when a predetermined distance is exceeded, a message to prompt the driver to change the oil ("3000 Km has been exceeded, please change the oil") is displayed in characters and a warning sound to advise the driver.

The drowsiness prevention / alarm function displays a sound or a warning sound at predetermined time intervals to relieve the driver's drowsiness, and based on acceleration measurement data such as meandering driving (unnatural rolling). This function displays a sound and a warning sound when a dangerous driving element is detected. A plurality of types of warning sounds can be selected, such as a buzzer sound, a patrol car siren, and an explosion sound. The drowsiness prevention function can select ON / OFF of the mode, the type of voice, and the time interval. Furthermore, a timer function is provided, and for example, by setting a wake-up time, it can be used as a wake-up.

The driving rank indicates the evaluation for each evaluation element (accelerator operation, brake operation, steering wheel operation, etc.) by using an index such as A to D. In addition, based on the evaluation values, the overall safe driving degree is displayed as a score or the like. Further, the result of the comprehensive evaluation is displayed by changing a character (for example, a character simulating an animal) that is an index of driving skill. This character is set in several types, and the result of one driving is determined by determining the character of the type and its expression (good, normal, bad, etc.) according to the comprehensive evaluation result (rank and score). Is done.

In addition to the above-mentioned character which is an index of driving skill, a mascot character (hereinafter referred to as a mascot character) which changes each time driving is performed and learns knowledge of safe driving and the like is provided. As the mascot character, a favorite character can be selected by a selection operation, and a character corresponding to the degree of difficulty relating to the progress of the game can be selected. In this example, at the start of the game, knowledge about safe driving is zero, and the mascot character changes according to the evaluation result of the driving skill,
It is designed to learn. For example, the ultimate goal is to make the character change and learn (the best state). If driving is good, the mascot character learns about safe driving, and if driving is bad, it does not learn anything, The game (training game or the like) is advanced by preventing any change or learning. In addition, when a predetermined score is obtained continuously in the overall evaluation score, for example, when 90 or more scores are obtained two consecutive times, a special game is started to motivate the driver to take a challenge for safe driving. I try to improve.
