Description

Technical Field

[0001] This invention belongs to the field of intelligent vehicle detection technology, and particularly relates to an intelligent vehicle detection system and method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Current intelligent vehicle detection systems often only detect the rear of the vehicle when it is reversing. During reversing, they lack detection of the vehicle's chassis and wheels. If there are differences in road surface height during reversing, such as the road surface to be reversed being higher or lower than the current road surface, the chassis will hit the intersection of the different road surfaces, damaging the chassis structure.

[0004] Similarly, when driving on a road with a significant curb, it's often difficult to visually determine whether crossing it will result in scraping the car's undercarriage, posing a risk. Furthermore, when there's a height difference between the road surface and the surrounding environment, the lack of monitoring of the car's undercarriage and wheels means that on roads with significant elevation changes, wheels can easily veer off the road, leaving one side of the car without power. This could lead to the car's wheels going off the curb or even the entire vehicle leaving the road. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a vehicle intelligent detection system to improve the driver's ability to cope with various road conditions and reduce the probability of wheels going off the road and chassis damage.

[0006] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0007] Firstly, a vehicle intelligent detection system is disclosed, comprising:

[0008] The wheel suspension height detection module, the wheel suspension length detection module, and the chassis detection module all communicate with the central control module.

[0009] The wheel suspension height detection module is used to detect the distance between the bottom of the wheel and the ground directly below the bottom of the wheel in real time. When the distance is greater than the safe height threshold, the wheel suspension length detection module is activated.

[0010] The wheel overhang length detection module is used to detect the length of the wheel overhang in real time.

[0011] The chassis detection module is used to detect the distance between the chassis and the ground in real time;

[0012] The central control module receives the data detected by the above detection modules and makes judgments accordingly. If the data exceeds the set threshold, it provides specific processing measures.

[0013] As a further technical solution, there are four wheel suspension height detection modules and four wheel suspension length detection modules, all located on the vehicle chassis near the tires, and the chassis detection module is located at the center of the vehicle chassis, all of which include sensing radar.

[0014] Secondly, a vehicle intelligent detection method is disclosed, including:

[0015] Real-time detection of the distance between the bottom of the wheel and the ground directly below the bottom of the wheel; when the distance is greater than a safe height threshold, real-time detection of the length of the wheel's suspended portion.

[0016] Real-time detection of the distance between the chassis and the ground;

[0017] Receive the data detected above and make judgments on each of them. If the data exceeds the set threshold, provide specific processing measures.

[0018] As a further technical solution, when the wheel suspension height is at a safe height, the wheel suspension height detection module sends the parameters in the wheel suspension height detection signal to the wheel suspension length detection module, at which time the wheel suspension length detection module does not start.

[0019] As a further technical solution, when the wheel suspension length detection module is activated, it automatically detects the length of the wheel in the suspension. When the length of the wheel suspension is within the safe length, the wheel suspension length detection module sends a parameter from the wheel suspension length detection signal to the central control module, at which time the central control module outputs a reminder message.

[0020] As a further technical solution, when the length of the wheel's suspended portion exceeds the safe length, the wheel suspended portion length detection module sends another parameter from the wheel suspended portion length detection signal to the central control module, and the central control module outputs another reminder message.

[0021] As a further technical solution, the chassis detection module detects the distance between the chassis and the ground in real time. When the chassis is within a safe distance from the ground, the chassis detection module sends the relevant information in the chassis ground clearance detection signal to the central control module, at which time the central control module does not take any action.

[0022] As a further technical solution, when the chassis ground clearance is less than the safe distance, the chassis detection module sends the danger signal information in the chassis ground clearance detection signal to the central control module, and the central control module outputs a reminder message.

[0023] The above one or more technical solutions have the following beneficial effects:

[0024] This invention, by setting up a wheel suspension height detection module and a wheel suspension length detection module, and defining multiple CAN signals, can alert the driver when there is a risk of the wheel being suspended in the air. This reduces the probability of the tire going off the curb and causing the vehicle to become immobile, and also reduces the probability of the vehicle going off the road, thereby improving the practicality and safety of the system.

[0025] This invention, by setting up a wheel suspension height detection module and defining various CAN signals, ensures that the invention will not alert the driver when the wheel is suspended in the air but the suspension height does not affect driving, thereby reducing the interference of the intelligent detection system on the driver while the vehicle is in motion.

[0026] This invention, by incorporating a chassis ground clearance detection module, can monitor the chassis ground clearance in real time when the vehicle traverses uneven road surfaces such as curbs. It alerts the driver when there is a risk of chassis scraping, thereby assisting the driver, reducing the probability of chassis damage, and improving vehicle safety.

[0027] When there is a risk of the wheels being suspended in the air, this invention can assist the driver in observing the height of the wheels being suspended in the air and the length of the wheel that has left the road surface when the central control module displays real-time images. The driver does not need to stick their head out of the window to observe, and the observation effect is more intuitive, improving driving comfort and reducing the interference of the external environment on the driver.

[0028] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0029] The accompanying drawings, which form part of this invention, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an improper limitation of the invention.

[0030] Figure 1 This is a system framework diagram of an embodiment of the present invention. Detailed Implementation

[0031] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0033] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0034] Example 1

[0035] See appendix Figure 1 As shown in the figure, this embodiment discloses a vehicle intelligent detection system, including an intelligent detection module and a central control module. The intelligent detection module includes a wheel suspension height detection module, a wheel suspension length detection module, and a chassis detection module.

[0036] There are four wheel suspension height detection modules and four wheel suspension length detection modules, all located on the vehicle chassis near the tires. The chassis detection module is located at the center of the vehicle chassis, and all include sensor radar.

[0037] The wheel suspension height detection module monitors the distance between the bottom of the wheel and the ground below it in real time. When the distance between the bottom of the wheel and the ground below it is greater than zero, the wheel is in a suspended state. When the wheel suspension height is within the safe height, the wheel suspension height detection module controls the wheel suspension length detection module to not start via CAN signal transmission. When the wheel suspension height exceeds the safe height, the wheel suspension height detection module controls the wheel suspension length detection module to start via CAN signal transmission.

[0038] The aforementioned wheel suspension height detection module contains a sensor radar, which measures the distance between the top of the tire and the ground. This distance is subtracted from the tire diameter to obtain the distance between the bottom of the tire and the ground below.

[0039] In this implementation example, the central control module is specifically the car's central control screen control system. It first detects the wheel's height above the ground. When the wheel's height above the ground exceeds the safe height, the wheel will drive off the road, and there will be a danger of the wheel being suspended above the ground. In this way, when the wheel drives off the road and is not suspended above the ground, no alarm will be triggered. An alarm will only be triggered when there is a danger of the wheel being suspended above the ground.

[0040] When the wheel overhang length detection module is activated, it automatically detects the length of the wheel overhang. When the overhang length is within the safe range, the module transmits a CAN signal to the central control module, which then alerts the driver that the wheel is partially overhanging. When the overhang length exceeds the safe range, the module transmits a CAN signal to the central control module, which then warns the driver that the overhang length is at a dangerous distance and transmits the simulated image from the radar distance sensor in the module to the central control module in real time.

[0041] The radar of the aforementioned wheel suspension length detection module is installed on the outermost side of the car chassis, next to the wheel, and can automatically detect the length of the wheel in the suspension section.

[0042] The chassis detection module monitors the distance between the chassis and the ground in real time. When the chassis is within a safe distance from the ground, the chassis detection module transmits a CAN signal to the central control module, which does not react. When the chassis is less than the safe distance from the ground, the chassis detection module transmits a CAN signal to the central control module, which then alerts the driver that the distance between the chassis and the ground is less than the safe distance and transmits the image detected by the chassis detection module to the central control module in real time.

[0043] The aforementioned chassis detection module includes multiple radars installed at various locations on the chassis. If a collision occurs at a location other than the center of the chassis, the corresponding radar can also detect that the chassis is less than the safe distance from the ground.

[0044] This invention defines CAN signals, as shown in Table 1:

[0048] Example 2

[0049] This embodiment discloses a vehicle intelligent detection method, including:

[0050] The wheel suspension height detection module monitors the distance between the bottom of the wheel and the ground below it in real time. When the distance between the bottom of the wheel and the ground below it is greater than zero, the wheel is in a suspended state. When the wheel suspension height is within the safe height, the wheel suspension height detection module sends the parameter "00: safe" from the wheel suspension height detection signal to the wheel suspension length detection module, at which time the wheel suspension length detection module is not activated. When the wheel suspension height exceeds the safe height, the wheel suspension height detection module sends the parameter "01: dangerous" from the wheel suspension height detection signal to the wheel suspension length detection module, at which time the wheel suspension length detection module is activated.

[0051] When the wheel suspension length detection module is activated, it automatically detects the length of the wheel suspension portion. When the wheel suspension length is within the safe range, the module sends the parameter "00: safe" from the wheel suspension length detection signal to the central control module. At this time, the central control module reminds the driver through sound that the wheel is partially suspended, but the length of the suspended portion is still within the safe range. When the wheel suspension length exceeds the safe range, the module sends the parameter "01: dangerous" from the wheel suspension length detection signal to the central control module. At this time, the central control module reminds the driver through louder sound and flashing warning text on the central control screen that the length of the vehicle suspension portion has reached a dangerous length. The module also transmits the image detected by the wheel suspension length detection module to the central control module in real time. The driver can observe the wheel suspension status more intuitively through the image from the central control module without having to stick their head out of the window to observe, reducing the impact of external factors such as rain and sand on the driver's driving, thereby improving driving safety and comfort.

[0052] The chassis detection module monitors the distance between the chassis and the ground in real time. When the chassis height is within a safe distance, the chassis detection module sends "00: safety height" from the chassis height detection signal to the central control module, which does not react. When the chassis height is less than the safe distance, the chassis detection module sends "00: dangerous height" from the chassis height detection signal to the central control module. At this time, the central control module reminds the driver to drive cautiously through sound and flashing warning text, and transmits the images detected by the chassis detection module to the central control module in real time. The driver can observe the chassis condition that is not visible to the naked eye, and more intuitively judge the vehicle status, thereby further assisting the driver and reducing the probability of chassis damage.

[0053] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
