Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a real-time display system for vehicle driving status and behavior. Background Technology

[0002] With the increasing intelligence of automobiles, more and more vehicles are equipped with autonomous driving or advanced driver assistance systems (ADAS). In existing systems, vehicles automatically respond to emergencies, such as emergency braking and obstacle avoidance. However, drivers may not be aware of the situation or the vehicle's response, leading to incorrect judgments within the extremely short reaction time. For example, a vehicle's obstacle avoidance maneuver might be misinterpreted by the driver as a loss of control, resulting in unsafe driving. In autonomous driving or ADAS, delayed information transmission hinders driver reaction, especially in emergencies. Effective information transmission, rapid response, and real-time display significantly improve driver safety and experience. Therefore, reducing the latency of real-time data transmission during vehicle operation, enabling rapid transmission and display of vehicle status and behavior to help drivers understand and assess the vehicle's condition, is a crucial technical challenge that needs to be addressed.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Figure 1 This diagram illustrates the structure of a real-time vehicle driving status and behavior display system according to an embodiment of the present invention. Figure 1 As shown, the real-time vehicle driving status and behavior display system of this embodiment includes: a sensor module 11, a response module 12, a central processing module 13, and a display module 14. The sensor module 11, the response module 12, and the display module 14 communicate with the central processing module 13 via optical fiber. The sensor module 11 detects vehicle environmental information and transmits the vehicle environmental information to the central processing module 13 via optical fiber. The response module 12 automatically performs a response action and sends the response action to the central processing module 13 via optical fiber. The central processing module 13 processes the vehicle environmental information to determine the vehicle driving status, generates warning information based on the vehicle driving status and response action, and transmits the warning information to the display module 14 via optical fiber. The display module 14 projects the warning information onto the vehicle's windshield using an augmented reality head-up display (AR-HUD).

[0019] In a specific embodiment, the sensors in the sensor module 11 collect information about the vehicle's surrounding environment, including obstacle information and vehicle driving information, and transmit the collected information to the central processing module 13 via optical fiber. The central processing module 13 analyzes and processes the sensor data to obtain the vehicle's driving status. In vehicles equipped with autonomous driving or advanced driver assistance systems, the response module 12 responds to various driving conditions. In emergency situations, the response module 12 automatically responds, including braking, steering to avoid obstacles, or suspension control, and transmits the response to the central processing module 13 via optical fiber. The central processing module 13 processes the sensor data and response, analyzes and judges the data, generates a warning message image, and transmits it to the display module 14 to display to the driver via AR-HUD, allowing the driver to understand the vehicle's driving status and the response actions being taken.

[0020] The sensor module 11 includes one or more sensors. Depending on the specific structure of the vehicle, multiple sensors supporting fiber optic interfaces are installed. The sensors include radar, cameras, and / or accelerometers. The radar measures speed and detects obstacles, the camera scans the vehicle's surrounding environment in real time, and the accelerometer monitors and provides feedback on the vehicle's movement status in real time, thereby obtaining information about the vehicle's surrounding environment. This information includes vehicle and obstacle information. Distance sensors or speed sensors can be added as needed to collect the distance and speed of obstacles. Sensors with fiber optic interfaces can be directly connected to optical fibers. The sensor module 11 transmits the vehicle's environmental information to the central processing module 13 via optical fibers.

[0021] The response module 12 is a collective term for all parts that respond to various driving conditions in autonomous driving or advanced driver assistance systems. In emergency situations, the vehicle chassis domain control module immediately executes operations to generate control commands, including integrated control of braking, steering, drive, and suspension. The chassis domain control module controls the response module 12 to automatically respond in emergency situations, including braking, steering to avoid obstacles, or suspension control. In emergency situations where there is a risk of collision, braking and steering are used to avoid obstacles. Suspension control refers to adjusting the stiffness and height of the suspension in real time according to road conditions and driving emergencies to achieve a better driving experience. In non-emergency situations, the central processing module 13 generates response information based on the vehicle's driving conditions. The response information includes braking or steering to avoid obstacles. The central processing module 13 sends the response information to the response module 12 via optical fiber. The response module 12 then performs corresponding response actions based on the response information, such as braking or steering to avoid obstacles. The response module 12 returns the response actions to the central processing module 13 in real time, and the central processing module 13 corrects the response information in real time based on the vehicle's driving conditions and the response actions.

[0022] The central processing module 13 and the response module 12 communicate bidirectionally via optical fiber. The central processing module sends response information to the response module 12, the response module 12 takes a response action, and feeds back the response action to the central processing module 13 in real time for correction. For example, if the response information sent by the central processing module 13 to the response module 12 is to turn left to avoid an obstacle, the response module 12 responds by turning left and returns the response status to the central processing module 13 in real time. If the central processing module 13 detects that the vehicle has avoided the obstacle, it corrects the response information to continue straight.

[0023] Before an emergency occurs, the central processing module 13 generates warning information based on the vehicle's driving status. This warning information includes phrases such as "obstacle ahead," "preparing to brake," and "person ahead on the left." The warning information is then sent to the display module 14, which projects it onto the vehicle's windshield via an AR-HUD, alerting the driver to prepare. When the vehicle response module 12 automatically responds to an emergency, the central processing module 13 generates alert information based on the vehicle's driving status and response behavior. This alert information is sent to the display module 14, which projects it onto the windshield via an AR-HUD. The alert information includes phrases such as "braking" and "turning left to avoid an obstacle," thus displaying the vehicle's driving status and behavior to help the driver understand the road conditions and the vehicle's actions. After the emergency ends, the central processing module 13 generates processing information based on the vehicle's driving status. The processing information includes "collision with an obstacle" and "scratching at the rear of the vehicle". The processing information is sent to the display module 14. The display module 14 projects the processing information onto the vehicle's windshield through AR-HUD, which can display the vehicle's handling of the emergency and whether it has scratched any obstacles or caused any damage to the vehicle.

[0024] Displaying too much information on the vehicle's windshield can distract the driver and reduce reaction efficiency. Therefore, information needs to be presented intelligently and reasonably to avoid information overload. The central processing module 13 sets the priority of various warning information. For example, the highest priority is hitting a person, which means that emergency action should be taken first; the medium-high priority is hitting an obstacle; and the low priority is speeding. When multiple warning information exists at the same time, the display module 14 displays the warning information through AR-HUD according to the priority and adjusts the display mode of the warning information. The warning symbols and warning information are set to be simple and eye-catching, so that the driver can easily notice them without being distracted.

[0025] Figure 2 A schematic diagram of the structure of a display module provided in an embodiment of the present invention is shown, as follows: Figure 2 As shown, the display module in this embodiment includes a warning message 21 and a windshield 22. The display module projects the warning message directly onto the windshield 22 of the vehicle via AR-HUD. The driver can see the warning message 21 while observing the road surface, without having to look down at the instrument panel or the central control screen, thus avoiding distraction. AR-HUD displays the vehicle's response behavior, such as braking and obstacle avoidance, in the shortest possible time, relieving the driver's confusion and uncertainty, increasing driver trust and enhancing safety.

[0026] AR-HUD technology refers to the use of a graphic display to generate images, which are then refracted and reflected by an optical projection system and precisely projected onto the windshield 22. Depending on the driver's height, driving habits, and vehicle driving conditions (e.g., uphill and downhill driving will cause the driver's line of sight to be different), AR-HUD technology will dynamically adjust the position, size, and angle of the projected image of the warning information 21 according to the vehicle's driving conditions and the driver's line of sight, so that different drivers can easily see the warning information 21 under different driving conditions, effectively reducing the risk of accidents.

[0027] The real-time vehicle driving status and behavior display system also includes an auxiliary display module, which includes sound and vibration elements. When the driver encounters an emergency while driving, the auxiliary display module will issue an auxiliary prompt, such as an audible prompt "There is an obstacle ahead" while the seat vibrates, reminding the driver to pay attention to driving safety and further reducing the risk of accidents.

[0028] Because vehicles travel at high speeds, there is only a very short time to react to any emergency. To maximize the real-time display of vehicle status and behavior and save driver reaction time, optical fiber is used as the transmission medium between the sensor module, response module, display module, and central processing module. Optical fiber communication has extremely high data transmission rates, supporting the real-time transmission of large amounts of data in this embodiment, ensuring rapid transmission of vehicle status and behavior in emergencies. Optical fiber communication has very low latency, ensuring that the reaction time in this embodiment is not affected by transmission delays. Low latency allows responses such as emergency braking and obstacle avoidance to be transmitted more quickly through the central processing module to the AR-HUD, achieving extremely low-latency real-time display. Compared to traditional copper wires, optical fiber has stronger resistance to electromagnetic interference. During high-speed driving, the risk of electromagnetic interference to the vehicle communication network is high; optical fiber communication ensures the stability of information in complex environments.

[0029] Optical fibers include single-mode fiber and multimode fiber. Single-mode fiber has a single transmission mode, and the optical signal can maintain a high degree of consistency when transmitted in the fiber, thus ensuring signal quality during long-distance transmission. Multimode fiber, on the other hand, allows multiple modes of light to be transmitted in parallel within the same fiber, playing an important role in short-distance communication. Based on the requirements of vehicles for short-distance, multi-channel transmission, this embodiment uses multimode fiber as the transmission medium. Multimode fiber supports multi-channel transmission and can transmit multiple different signals simultaneously, improving information transmission efficiency.

[0030] Specifically, the use of fiber optic communication and AR-HUD is aimed at improving the speed at which drivers can obtain information and reducing latency. Fiber optic communication has the characteristics of high bandwidth, low latency and strong anti-interference. It is used to reduce the latency of real-time data transmission in the vehicle, while AR-HUD is used to reduce the latency of drivers obtaining warning information. The combination of the two allows the vehicle's driving status and emergency response behavior to be displayed with extremely low latency, helping drivers understand and judge the vehicle's condition.
