Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of driving assistance, in particular to a new driver driving assistance method and system. BACKGROUND

[0002] The reversing radar is one of the most common reversing assistance technologies. It mainly sends high-frequency sound waves through ultrasonic sensors. When these sound waves encounter obstacles, they will be reflected back and received by the sensor and converted into electrical signals. The system calculates the distance of the obstacle according to the time difference of the sound waves going back and forth, combined with the speed of sound, and sends different frequency sounds through the buzzer or displays the distance value and image on the display screen to remind the driver. The reversing radar has the characteristics of instant feedback and strong blind area coverage, and is especially suitable for use in complex urban environments. However, the reversing radar technology is prone to cause dependence habits in drivers, but the technology itself cannot cover all reversing scenarios, and has certain defects. During use, if it is relied on too much, it may cause the driver to relax when reversing, ignoring the comprehensive observation of the vehicle's surroundings. Therefore, the new driver's vigilance and reversing technology should be cultivated at the same time when using this assistance technology, so as to avoid driving safety accidents caused by excessive reliance on assistance driving technology but lack of common sense.

[0003] The rearview mirror reversing assistance system is a system that combines image and sound prompts. It relies on a camera at the back of the car to present the road conditions behind the car on the central display screen and intuitively inform the driver of the relative position of the car and the obstacle through images or sounds. This system can eliminate the problems caused by the blind area of the rearview mirror, provide convenience for the driver when reversing and parking, and eliminate safety hazards. However, the rearview mirror reversing assistance technology is prone to cause dependence habits in drivers, but the technology itself cannot cover all reversing scenarios, and has certain defects. During use, if it is relied on too much, it may cause the driver to relax when reversing, ignoring the comprehensive observation of the vehicle's surroundings. Therefore, the new driver's vigilance and observation ability of the physical reversing mirror should be cultivated at the same time when using this assistance technology, so as to avoid driving safety accidents caused by excessive reliance on assistance driving technology but lack of common sense.

The use of user data in the technical solutions complies with relevant national laws and regulations (e.g., "Information Security Technology Personal Information Security Specification"). For example, appropriate measures are taken for personal information access control; restrictions are given for the display of personal information; the use purpose of personal information does not exceed the direct or reasonably related range; the use of personal information eliminates explicit identity pointing and avoids precise positioning to a specific individual.

[0045] In related technologies, the reversing radar is one of the most common reversing assistance technologies. It mainly sends high-frequency sound waves through ultrasonic sensors, which are reflected back when encountering obstacles and are received by the sensors and converted into electrical signals. The system calculates the distance of the obstacle according to the time difference of the sound waves going back and forth, combined with the speed of sound, and issues different frequency sounds through the buzzer or displays distance values and images on the display screen to remind the driver. The reversing radar has the characteristics of instant feedback and strong blind area coverage, and is especially suitable for use in complex urban environments. However, the current reversing radar technology has the following defects:

[0046] 1. Easy to misreport: The probe of the reversing radar is easy to misreport under certain conditions. For example, when the probe surface is frozen, muddy, snowy or covered with water vapor, the system may identify these non-obstacles as obstacles, thus issuing false alarm signals. The reversing radar may sometimes fail to detect some small obstacles such as towing hooks, thin horizontal bars, fences and thin columns, which may cause the driver to fail to timely detect and avoid these obstacles when reversing, thus causing scratching or collision accidents.

[0047] 2. Easy to be disturbed by external factors: The ultrasonic signals of the reversing radar may be disturbed by external environmental factors during transmission, such as strong winds, bad weather conditions such as rain and snow, and other sound sources (such as other vehicles' reversing radars, motorcycles, etc.) around the vehicle. These disturbances may cause the detection accuracy of the reversing radar to decrease or misreport.

[0048] 3. Limited detection range: The detection range of the reversing radar is usually conical and limited. In complex or narrow parking environments, the reversing radar may not be able to fully cover all areas behind the vehicle, leaving a detection blind area. The driver needs to pay special attention to these blind areas when reversing to avoid accidents.

[0049] 4. High damage rate: Since the probe of the reversing radar is usually exposed outside the vehicle and is often affected by factors such as car washing with water guns and poor road conditions, its damage frequency is relatively high. Once the probe is damaged, it will affect the normal use of the reversing radar, which needs to be replaced or repaired in time.

[0050] 5. Excessive dependence may reduce driver alertness: Although the reversing radar can provide real-time obstacle distance information, excessive dependence on it may cause the driver to relax when reversing, ignoring the comprehensive observation of the vehicle's surroundings.

[0051] In summary, the reversing radar technology is prone to cause reliance habits among drivers, but the technology itself cannot cover all reversing scenarios and has certain defects. During use, over-reliance on it may cause drivers to relax their vigilance when reversing and ignore comprehensive observation of the vehicle's surroundings. Therefore, while using this auxiliary technology, novice drivers should be trained to be vigilant and develop reversing skills to avoid driving safety accidents caused by over-reliance on auxiliary driving technology but lack of common sense.

[0052] The rearview mirror reversing assistance system is a system that combines images and sound prompts. It relies on a camera at the back of the vehicle to present the road conditions behind the car on the central display screen and intuitively inform the driver of the relative position of the vehicle and obstacles through images or sound. This system can eliminate the problems caused by the blind area of the rearview mirror, provide convenience for drivers when reversing and parking, and eliminate safety hazards. However, the current rearview mirror reversing assistance technology has the following defects:

[0053] 1. Picture distortion and distance misjudgment: In order to obtain a larger picture angle, the reversing image system usually uses a wide-angle lens. Although this design can provide a wider field of view, it can also cause picture distortion, resulting in a deviation between the distance displayed on the screen and the actual distance. When observing the reversing image, the driver may misjudge the distance due to picture distortion, increasing the risk of collision.

[0054] 2. Picture delay: The reversing image system needs a certain amount of time to process and transmit image signals, so there may be a problem of picture delay. If the delay time is too long, the picture the driver sees when reversing may be the scene a few seconds ago, which will prevent the driver from reacting in time and increase the risk of collision.

[0055] 3. Light influence: The reversing image system relies on the camera to capture images, so the light conditions have a great influence on the image quality. In strong light, weak light, or adverse weather conditions (such as heavy rain, heavy fog), the picture quality of the reversing image may decrease significantly, and the driver may not be able to see the obstacles behind the vehicle, affecting the driver's judgment and decision-making.

[0056] 4. Camera position and field of view limitation: The camera of the reversing image system is usually installed at the back of the vehicle, and its field of view is limited. Some low or blind areas behind the vehicle may not be captured by the camera, so the driver needs to pay special attention to these blind areas when reversing.

[0057] In summary, the rearview mirror backup assistance technology is prone to cause reliance habits for drivers, but the technology itself cannot cover all backup scenarios and has certain defects. During use, over-reliance on it may cause drivers to relax their vigilance when backing up and ignore comprehensive observation of the surrounding environment of the vehicle. Therefore, the vigilance and observation of the entity backup mirror ability of novice drivers should be cultivated while using the assistance technology to avoid driving safety accidents caused by over-reliance on the assistance driving technology but lack of common sense.

[0058] The technical problem solved by the present application is that the technical solution of the present application aims to solve the problem of over-reliance on existing backup assistance technology by novice drivers, ignoring personal driving skills and lack of vigilance.

Adjust the left rearview mirror: since the left rearview mirror is close to the driver, the dead angle on the left side of the vehicle is relatively small for the left rearview mirror, and the line of sight is generally good. Adjust the image of the horizon in the left rearview mirror to the center of the mirror, and at the same time, adjust the image of the left side of the vehicle to occupy 1 / 4 of the right side of the mirror, that is, two-thirds of the sky and two-thirds of the earth, and one-fourth of the vehicle.
