Description

Technical Field

[0001] This utility model relates to the field of automotive safety technology, specifically to an intelligent automotive safety warning and collision avoidance device. Background Technology

[0002] Currently, most automotive safety warning and collision avoidance devices adopt a split design. The warning function relies on folding triangles or electronic warning signs, which need to be manually placed 50-150 meters behind the accident vehicle. Collision protection relies on the vehicle's own airbags or external energy-absorbing boxes. These devices require manual operation by the driver, who visually estimates the distance to place the warning signs. In low visibility or complex road conditions such as heavy fog, heavy rain, and curves, positioning errors are very likely to occur.

[0003] However, when accidents occur on slopes, curves, or in low-visibility areas, there may be an irreconcilable temporal and spatial misalignment between existing manually deployed warning positioning and the protection requirements of the accident scenario. This can result in drivers of following vehicles not having enough safe braking distance by the time they see the warning. In such cases, even with collision avoidance structures, the inaccurate warning positioning cannot form an effective collision buffer layer, leading to a secondary collision that could have been avoided. Utility Model Content

Detailed Implementation

[0013] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0014] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0015] Example 1 Figure 1 A schematic diagram of the overall structure of an intelligent vehicle safety warning and collision avoidance device is shown, as follows: Figure 1 As shown, this embodiment provides an intelligent vehicle safety warning and collision avoidance device, including: Main control module 1, mobile carrier module 2, warning function module 3, buffer function module 4, and positioning interaction module 5; The main control module 1 establishes electrical signal connections with the mobile carrier module 2, the warning function module 3, the buffer function module 4, and the positioning interaction module 5, respectively. The mobile bearing module 2 is used to respond to the displacement command of the main control module 1 and drive the wheel set to perform forward / stop operations; The warning function module 3 is used to generate visible light signals and sound wave warning signals after receiving the deployment command from the main control module 1. The buffer function module 4 is used to inflate the airbag in response to the collision warning command of the main control module 1. The positioning interaction module 5 is used to generate spatial coordinate data of the undercarriage suspension bracket, control the telescopic mechanism to perform suspension / release actions, and provide real-time feedback of the position offset of the moving platform to the main control module 1. The main control module 1 is used to parse remote control commands and distribute them to the corresponding functional module of one of the mobile carrier module 2, the warning function module 3, the buffer function module 4, and the positioning interaction module 5.

[0016] When an accident occurs, the driver sends a start command to the main control module 1 via remote control. After parsing the command, the main control module 1 simultaneously activates the positioning interaction module 5 and the mobile load-bearing module 2. The positioning interaction module 5 calculates the three-dimensional spatial coordinates of the undercarriage suspension bracket in real time through laser phase scanning and electromagnetic field gradient detection, and feeds back the position offset to the main control module 1. Based on this, the main control module 1 generates a displacement command to drive the mobile load-bearing module 2 to move. The wheel set execution submodule 203 autonomously moves to the target position along the optimal path based on the slope adaptive torque algorithm. Upon reaching the target point, the main control module 1 sends an unfolding command to the warning function module 3. The command response submodule 301 triggers the optical warning submodule 302 to unfold the folding support frame and activate the red and yellow dual-color LEDs to flash alternately. Simultaneously, the acoustic warning submodule is activated to emit intermittent sound waves. When the radar detects the risk of brake failure of the vehicle behind, the main control module 1 sends a collision warning command to the buffer function module 4. The warning analysis submodule 401 sets the inflation pressure threshold according to the risk level. The gas management submodule 402 detonates the electric detonator to release high-pressure inert gas. The airbag control submodule 403 completes the airbag inflation within 3 seconds and activates the puncture resistance enhancement layer to form an adaptive buffer layer.

[0017] In this example, firstly, the centimeter-level coordinate calculation of the positioning interaction module 5 and the closed-loop path control of the mobile bearing module 2 can completely eliminate the 3-meter-level positioning deviation caused by manual placement, ensuring that the warning device is always in the optimal protective position. Secondly, the buffer function module 4 uses risk-level-based inflation pressure control (e.g., three adjustable levels of 6 / 10 / 15 kPa) and dynamic adjustment of the airbag expansion rate to reduce vehicle structural damage in secondary collisions. Finally, the cascaded control of the five modules' electrical signals enables full automation from accident perception to protective deployment, minimizing the risk of buffer failure due to inaccurate positioning.

[0018] This example provides an intelligent vehicle safety warning and collision avoidance device. Through a five-dimensional collaborative control architecture consisting of a main control module 1, a mobile support module 2, a warning function module 3, a buffer function module 4, and a positioning interaction module 5, a closed-loop protection system of "accident perception-positioning deployment-dynamic protection" is constructed. After the main control module 1 parses the remote control command, the positioning interaction module 5 calculates the spatial coordinates of the vehicle's undercarriage suspension bracket in real time and generates position offset data, driving the mobile support module 2 to autonomously move to a target point with centimeter-level precision. Simultaneously, the warning function module 3 is triggered to deploy a dual-mode audible and visual warning signal. When the collision warning command is activated, the buffer function module 4 controls the airbag inflation pressure threshold and expansion rate based on risk level parameters, forming an adaptive buffer layer between the accident vehicle and the following vehicle. This addresses the technical problem that existing manually deployed warning positioning may have irreconcilable spatiotemporal misalignments with accident scenario protection requirements, leading to insufficient safe braking distance by the time the following vehicle driver notices the warning, potentially resulting in an avoidable secondary collision.

[0019] Figure 2 A schematic diagram of the specific structure of a mobile support module for an intelligent vehicle safety warning and collision avoidance device is shown, as follows: Figure 2 As shown, in one possible implementation, the mobile carrier module 2 includes: Instruction processing submodule 201, drive control submodule 202 and wheel group execution submodule 203; The instruction processing submodule 201 is electrically connected to the main control module 1, the drive control submodule 202 is electrically connected to the instruction processing submodule 201, and the wheel assembly execution submodule 203 is electrically connected to the drive control submodule 202. The instruction processing submodule 201 is used to receive the displacement instruction sent by the main control module 1, perform path calculation and conflict verification on the displacement instruction, and generate a drive control instruction containing a velocity vector. The drive control submodule 202 is used to parse the speed vector parameters in the drive control command, generate differential control signals for the left / right wheel sets, monitor the motor voltage / current status in real time and report any abnormalities. The wheelset execution submodule 203 is used to respond to differential control signals to drive the electric wheelset forward, dynamically adjust the torque output based on the road slope, and activate the electromagnetic brake to lock the axle in parking mode.

[0020] The operation of the mobile load-bearing module 2 begins with a displacement command issued by the main control module 1. After receiving the command, the command processing submodule 201 performs path calculation and conflict verification, generating a drive control command containing velocity vectors to plan the optimal travel route. The drive control submodule 202 parses the velocity vector parameters, converts them into differential control signals for the left and right wheel sets, and continuously monitors the motor's operating status, feeding back any abnormal conditions to the command processing layer. The wheel set execution submodule 203 responds to the differential control signal to drive the electric wheel set forward. On slopes, it automatically increases torque output to maintain a constant speed. When a parking command is triggered, it immediately activates the electromagnetic brake to lock the wheel axle, forming a closed-loop displacement system of "command calculation - differential control - dynamic execution".

[0021] In this example, multiple safeguards are achieved through the cascading control of three-level sub-modules. The conflict verification function of the instruction processing sub-module 201 avoids timing interference with warning or inflation actions; the differential signal conversion of the drive control sub-module 202 ensures precise steering under complex road conditions; and the slope adaptation and electromagnetic parking mechanism of the wheel set execution sub-module 203 jointly ensure the stable displacement capability of the mobile platform on icy and slippery roads, so that the warning and anti-collision device always accurately reaches the target protection position.

[0022] Figure 3 A schematic diagram of the specific structure of the warning function module of an intelligent vehicle safety warning and collision avoidance device is shown, such as... Figure 3 As shown, in one possible implementation, the warning function module 3 includes: Command response submodule 301, optical warning submodule 302, and acoustic warning submodule; The command response submodule 301 is electrically connected to the main control module 1, the optical warning submodule 302 is electrically connected to the command response submodule 301, and the acoustic warning submodule is electrically connected to the command response submodule 301. The instruction response submodule 301 is used to parse the deployment instruction sent by the main control module 1, and then generate a synchronous trigger signal for optical / acoustic warning, while monitoring the ambient light intensity and feeding it back to the main control module 1. The optical warning submodule 302 is used to unfold the folding support frame in response to a trigger signal and control multiple LED chips to generate alternating red and yellow flashing light signals; The acoustic warning submodule is used to activate the piezoelectric speaker in response to a trigger signal.

[0023] The activation of the warning function module 3 begins with an unfolding command issued by the main control module 1. The command response submodule 301 first parses the command and generates a synchronous trigger signal for both optical and acoustic warnings. Simultaneously, this submodule monitors changes in ambient light intensity in real time and feeds back the perceived data to the main control module 1. Upon responding to the trigger signal, the optical warning submodule 302 drives the folding support frame to unfold to its working position, controlling the LED light source integrated at the top of the frame to alternately display red and yellow dual-color light signals. Its luminous intensity is dynamically adjusted according to ambient light conditions to ensure optimal visibility. Simultaneously, the acoustic warning submodule activates the piezoelectric sound-generating unit to produce spatially penetrating warning sound waves, creating a complementary warning effect with the light signal in low-visibility environments.

[0024] This example achieves dual protection through the coordinated operation of three sub-modules. The synchronous signal generation mechanism of the instruction response sub-module 301 ensures that light waves and sound waves are strictly aligned in the time dimension, avoiding the recognition delay caused by the disconnect between sound and light in traditional warning devices. The folding mechanism of the optical sub-module achieves rapid and reliable unfolding under the drive of electrical signals, and together with the adaptive dimming strategy, it ensures the effectiveness of warnings under different lighting conditions. The directional sound wave propagation characteristics of the acoustic sub-module effectively overcome signal attenuation in rain and fog environments, forming a three-dimensional warning system covering the visible light and auditory dimensions, enabling drivers of vehicles behind to obtain warning information in a timely manner in complex road conditions.

[0025] Figure 4 A schematic diagram of the specific structure of the buffer function module of an intelligent vehicle safety warning and collision avoidance device is shown, such as... Figure 4 As shown, in one possible implementation, the buffer function module 4 includes: Early warning analysis submodule 401, gas management submodule 402 and airbag control submodule 403; The early warning analysis submodule 401 is electrically connected to the main control module 1, the gas management submodule 402 is electrically connected to the early warning analysis submodule 401, and the airbag control submodule 403 is electrically connected to the gas management submodule 402. The early warning parsing submodule 401 is used to parse the risk level parameters in the collision early warning command to generate the inflation pressure threshold and response timing command. The gas management submodule 402 is used to activate the electric detonation tube trigger circuit of the high-pressure inert gas container and generate a failure lock-up signal for the disposable container after the gas is released. The airbag control submodule 403 is used to control the expansion rate according to the inflation pressure threshold.

[0026] The protection mechanism of the buffer module 4 is triggered by the collision warning command from the main control module 1. The warning analysis submodule 401 first analyzes the risk level parameters in the command and generates differentiated inflation pressure thresholds and dynamic response timing accordingly. After responding to the timing command, the gas management submodule 402 activates the electric detonator trigger circuit, releases the compressed gas in the high-pressure inert gas container, and automatically generates a container failure lock-up signal after the gas release process is completed, ensuring the safe isolation of the disposable unit. Simultaneously, the airbag control submodule 403 adjusts the airbag expansion rate according to the preset pressure threshold. By dynamically adjusting the expansion process of different areas, the airbag shape adapts to the real-time collision risk level, forming an adaptive buffer structure.

[0027] This example achieves triple protection through closed-loop control of multi-level sub-modules. The risk level mapping mechanism of the early warning analysis sub-module 401 transforms the qualitative assessment of collision threats into precise inflation control parameters; the gas management sub-module 402 coordinates the electric explosion triggering and safety locking to ensure both the reliability of gas release and the operational safety after use; and the rate regulation function of the airbag control sub-module 403 ensures that the airbag maintains the optimal impact resistance shape during expansion, enabling the flexible buffer layer to form a dynamically adaptable protective interface between the accident vehicle and the following vehicle, significantly improving the vehicle protection efficiency in secondary collisions.

[0028] Figure 5 A schematic diagram of the positioning interaction module of an intelligent vehicle safety warning and collision avoidance device is shown, as follows: Figure 5 As shown, in one possible implementation, the positioning interaction module 5 includes: Positioning and sensing submodule 501, mechanical control submodule 502 and fusion processing submodule 503; The positioning and sensing submodule 501 is electrically connected to the fusion processing submodule 503, the mechanical control submodule 502 is electrically connected to the fusion processing submodule 503, and the fusion processing submodule 503 is electrically connected to the main control module 1. The positioning and sensing submodule 501 is used to scan the laser phase features of the metal structure of the vehicle chassis and output the raw positioning data stream with environmental compensation. The mechanical control submodule 502 is used to control the excitation current of the electromagnet of the telescopic mechanism; The fusion processing submodule 503 is used to perform multi-source fusion calculation on the original positioning data stream to generate the spatial coordinates of the suspension bracket.

[0029] The operation of the positioning interaction module 5 begins with the positioning perception submodule 501 scanning the three-dimensional spatial features of the vehicle chassis. By collecting physical characteristic data of the metal structure and applying an environmental compensation algorithm, it outputs an optimized raw positioning data stream. The fusion processing submodule 503 receives this data stream and performs multi-source fusion calculations to construct a spatial coordinate model of the suspension bracket. Simultaneously, it dynamically allocates system resources according to the instructions of the main control module 1. The mechanical control submodule 502 generates electromagnetic excitation control signals based on the fusion processing results. By adjusting the magnetic strength of the telescopic mechanism, it achieves reliable switching of the suspension state, enabling the mobile platform to autonomously switch between suspended fixed and ground deployment modes.

[0030] This example achieves precise positioning control through a three-tiered processing chain. The environmental compensation mechanism of the positioning perception submodule 501 effectively overcomes the impact of vehicle vibration and weather interference on the scanning data; the multi-source solution of the fusion processing submodule 503 transforms discrete data into high-confidence spatial coordinates; and the electromagnetic excitation adjustment of the mechanical control submodule 502 ensures the stable operation of the telescopic mechanism under different load conditions. Ultimately, a closed-loop positioning service system of "environmental perception → coordinate generation → mechanism control" is formed, establishing a spatial reference for the path planning of the mobile bearing module 2 and the collision protection of the buffer module.
