Abstract
Description
Technical Field
[0001] This invention relates to the field of safety protection technology for motorized two-wheeled vehicles, and specifically to a collision protection method and system applicable to motorized two-wheeled vehicles. Background Technology
[0002] With the rapid development of the economy, motorcycles have become a major means of transportation, and are loved by the public for their economy, speed and ease of operation. However, because motorcycles are relatively unstable, riding a motorcycle is jokingly referred to as "meat wrapped in iron." In addition, many drivers have a weak sense of safety, so once an accident occurs, it is very easy to cause injury or death.
[0003] For motorcyclists' self-protection, the conventional approach is to use external equipment such as helmets, knee pads, and protective clothing. While these external devices offer some protection, they are not mandatory and are subject to subjective choice; wearing them is optional, leading to inconsistent safety. Another approach relies on the motorcycle's built-in airbags and their control system. This method is mandatory and activates upon impact. However, its current limitation is that it only provides indiscriminate collision protection and cannot adapt to different collision scenarios to provide targeted protection for the motorcyclist, resulting in either over-protection or under-protection. Summary of the Invention
[0004] The present invention aims to provide a collision protection method and system suitable for motorized two-wheeled vehicles, in order to solve the technical problem that existing motorcycle collision protection systems cannot adapt to different collision situations to provide targeted protection for motorcycle drivers, resulting in over-protection or under-protection.
[0005] The basic solution provided by this invention is a collision protection method applicable to motorized two-wheeled vehicles, the method comprising the following steps: S01, Collect collision data, which is used to represent different collision types and different collision degrees; S02, Data Analysis: Based on collision data analysis, determine the possible outcomes of a collision accident, including the impact point and potential injury severity of the occupants of the motorized two-wheeled vehicle. S03, Protection Execution: Based on the possible collision landing point, the corresponding collision sensor is triggered to generate a trigger signal, which is then sent to the main control device via a signal line. After receiving the trigger signal, the main control device, in conjunction with the analyzed possible degree of injury, triggers the corresponding protective equipment to perform differentiated protection based on different collision types and degrees.
[0006] The working principle and advantages of this invention are as follows: it collects collision data representing different collision types and degrees, providing data support for subsequent targeted protection; it analyzes the collected collision data to obtain possible collision accident results, including the collision impact location and possible injury degree of the motor vehicle occupants; it triggers corresponding collision sensors by the collision impact location, and at the same time triggers corresponding protective equipment for differentiated protection in combination with the possible injury degree.
[0007] Compared with existing technologies, this invention links the triggering of the protective device with the collision type and collision severity. It can predict the collision landing point and possible injury level based on collision data, and trigger the corresponding protective device in a targeted manner to provide targeted protection measures for drivers and passengers. This makes the protection more reasonable and proposes a more targeted, safer, more reasonable and more universal safety protection method, thereby reducing the incidence of injuries and fatalities among drivers and passengers.
[0008] Furthermore, the data acquisition in S01 involves first acquiring a first set of data to determine different collision types, and then acquiring a corresponding second set of data based on the determined collision types to determine different collision degrees.
[0009] Beneficial effects: Determining the collision type before conducting targeted data collection can improve the effectiveness and speed of data acquisition, providing a data foundation for subsequent differential triggering protection devices.
[0010] Furthermore, the collision types include single-occupant multi-vehicle collision, single-occupant single-vehicle collision, two-occupant multi-vehicle collision, and two-occupant single-vehicle collision.
[0011] Beneficial effects: The analysis of collisions involving motorized two-wheeled vehicles is more comprehensive, covering the combination of the number of occupants and the collision method. Since two-person driving is more dangerous than single-person driving, the personnel are first distinguished, and then targeted and centralized protection is carried out after being associated with the corresponding protection devices, thereby improving safety protection performance and achieving higher safety protection.
[0012] Furthermore, the first data set includes the load-bearing points of the motorized two-wheeled vehicle, the corresponding load-bearing capacity of the load-bearing points, view data of potential collisions around the vehicle, and the vehicle's speed.
[0013] Beneficial effect: It enables effective collision type differentiation.
[0014] Furthermore, the second data set includes the motorized two-wheeler's speed, direction of fall, collision speed, collision force, collision angle, point of impact, and contact area.
[0015] Beneficial effects: The selected data can effectively predict and analyze the degree of collision.
[0016] Furthermore, in S02, the collision impact point location includes the front side, rear side, left side, and right side of the vehicle; the possible injury level includes first-degree injury, second-degree injury, and third-degree injury; the possible injury level is determined by analyzing the collision data, which initially determines the corresponding level of possible injury based on the collision type, and increases the level of possible injury accordingly when the collision data determining the collision level exceeds a set threshold.
[0017] Beneficial effects: By classifying the potential severity of injury and varying the severity in stages according to the type and intensity of the collision, the protective devices that are ultimately triggered can provide more targeted protection.
[0018] Furthermore, in S03, the collision sensors include front, rear, left, and right side collision sensors, which correspond to and are triggered by the collision impact points on the front, rear, left, and right sides of the vehicle, respectively; the protective equipment includes an on-board protective device and a wearable protective device; the method of triggering the corresponding protective equipment based on the possible injury level determined by the analysis provides differentiated protection based on different collision types and different collision levels, namely, when the analyzed possible injury level is level three injury, the on-board protective device is triggered; when the analyzed possible injury level is level two or level one injury, both the on-board protective device and the wearable protective device are triggered.
[0019] Beneficial effects: By correlating the collision point with the collision sensor, comprehensive and effective control can be achieved, and targeted protection can be provided based on the possible degree of injury.
[0020] Furthermore, when the analyzed possible injury level is level two or level one, the vehicle-mounted protection device and the wearable protection device are triggered as follows: when the analyzed possible injury level is level two, the vehicle-mounted protection device corresponding to the collision point is triggered; when the analyzed possible injury level is level one, the vehicle-mounted protection device corresponding to the collision point and the collision point on both sides is triggered.
[0021] Beneficial effects: Based on the level of potential injury, the corresponding vehicle protection device is effectively triggered, balancing effective protection and reducing the possibility of overprotection or underprotection by the vehicle protection device.
[0022] This invention is based on a collision protection method applicable to motorized two-wheeled vehicles, and also provides a collision protection system applicable to motorized two-wheeled vehicles to solve the technical problem that existing motorcycle collision protection systems cannot adapt to different collision situations to provide targeted protection for motorcycle drivers, resulting in over-protection or under-protection.
[0023] This includes the electrically connected data acquisition end, analysis end, and execution end; The data acquisition terminal is used to collect collision data representing different collision types and different collision degrees; The analysis terminal is used to analyze the collision data to determine the location of the impact point and the possible degree of injury to the driver and passengers of the motorized two-wheeled vehicle. The execution end is used to trigger the corresponding collision sensor according to the possible collision landing point, generate a trigger signal, and send the trigger signal to the main control device through a signal line; after receiving the trigger signal, the main control device, in conjunction with the analyzed possible degree of injury, triggers the corresponding protective equipment to provide differentiated protection based on different collision types and different collision degrees.
[0024] Beneficial effects: The device has a clear control logic and can trigger the corresponding protection devices in a targeted manner according to the actual collision situation to provide more appropriate safety protection for drivers and passengers, avoiding over-protection or under-protection, which could cause secondary injuries to drivers and passengers.

[0025] Figure 1 A flowchart illustrating a collision protection method for motorized two-wheeled vehicles provided in an embodiment of the present invention; Figure 2 This is a schematic diagram illustrating a collision between a motorized two-wheeled vehicle and a car, provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the collision protection system for motorized two-wheeled vehicles provided in an embodiment of the present invention. Detailed Implementation
[0026] The following detailed explanation illustrates the specific implementation methods: The basic implementation examples are as follows: Figure 1 The following is an example of a collision protection method applicable to motorized two-wheeled vehicles, comprising the following steps: S01, Collect collision data, which is used to represent different collision types and different collision degrees; Specifically, the first data set is collected to determine different collision types. Then, based on the determined collision types, the corresponding second data set is collected to determine different collision degrees. By first determining the collision type and then collecting targeted data, the effectiveness and processing speed of data collection can be improved, providing a data foundation for subsequent differential triggering protection devices.
[0027] Collision types include single-occupant multi-vehicle collisions, single-occupant single-vehicle collisions, two-occupant multi-vehicle collisions, and two-occupant single-vehicle collisions. The first data set includes the load-bearing points of the motorized two-wheeled vehicle, the corresponding load capacity of each load-bearing point, the view data of potential collision objects around the vehicle, and their speed. The load-bearing points and their corresponding load capacities can be used to determine whether the vehicle is driven by one person or two people. Specifically, when a passenger sits on the motorized two-wheeled vehicle, the load-bearing points and their corresponding load capacities are detected by a detection device on the seat. If there is one load-bearing point and its corresponding load, it is determined to be single-person driving; if there are two load-bearing points and their corresponding load capacities, it is determined to be two-person driving. The view data and speed of potential collision objects around the motorized two-wheeled vehicle can be used to determine whether a collision is a multi-vehicle collision or a single-vehicle collision. Specifically, if a potential collision object is determined to be moving rapidly towards the vehicle, it is determined to be a multi-vehicle collision; if a potential collision object is determined to be stationary, it is determined to be a single-vehicle collision. This combination of passenger numbers and collision types covers all collision scenarios for motorized two-wheeled vehicles, providing a more comprehensive analysis. Furthermore, since two-person driving has a higher risk factor than single-person driving, the system first distinguishes between passengers and then associates them with appropriate protective devices for targeted and centralized protection, improving safety performance and achieving higher levels of safety protection.
[0028] The second data set includes the motorized two-wheeler's speed, fall direction, collision speed, collision force, collision angle, collision point, and contact area. The collision point is indicated from a directional point, and the contact area is the specific point of contact between the motorcycle and the vehicle. When the collision type is a single-person multi-vehicle collision, the second data set includes the collision speed, collision angle, collision point, and the contact area between the motorcycle and the vehicle. When the collision type is a single-person single-vehicle collision, the second data set includes the motorized two-wheeler's speed, fall direction, collision speed, and collision force. When the collision type is a two-person multi-vehicle collision or a two-person single-vehicle collision, compared to the above single-person multi-vehicle collision and single-person single-vehicle collision, the offset direction of the passengers is added, which can be obtained by collecting and analyzing relevant data through the positioning device on the passengers' helmets.
[0029] S02, Data Analysis: Based on collision data analysis, determine the possible outcomes of a collision accident, including the impact point and potential injury severity of the occupants of the motorized two-wheeled vehicle. Specifically, the collision impact points include the front, rear, left, and right sides of the vehicle. like Figure 2 As shown, when a single-vehicle collision occurs, if the point of impact is at the 12 o'clock position and the contact point is the front wheel of the two-wheeled motorcycle, the driver will be thrown forward by inertia. Based on the analysis of the collision position, the driver will land in front of the two-wheeled vehicle.
[0030] In the event of a multi-vehicle collision, for example, when a passenger car collides with a two-wheeled vehicle at the 3 o'clock position, and the collision angle is 90°, the impact force is determined by the formula F=m The calculation is as follows: a = (v1 - v2) / (t1 - t2), where F represents the collision force, m represents the vehicle mass, and a represents the vehicle acceleration. The acceleration calculation formula is a = (v1 - v2) / (t1 - t2), where v represents the initial velocity and t represents time. The collision velocity calculation formula is: v = (m1 - m2) / (t1 - t ... v1+m2 v2) / (m1+m2).
[0031] When the collision speed is ≥40km / h, the protection device will be triggered to analyze the data and protect the driver of the motorized two-wheeled vehicle.
[0032] The potential injury levels are categorized into Level 1, Level 2, and Level 3, with Level 1 being the most severe. The potential injury level is determined based on collision data analysis. Initially, the potential injury level is determined according to the collision type. For example, when involving single-person driving, the potential injury level is categorized into Level 1, Level 2, and Level 3. When involving two-person driving, the potential injury level is higher than in single-person driving, directly categorized into Level 1 and Level 2, triggering the corresponding protective devices. When the collision data determining the degree of collision exceeds a set threshold, the potential injury level is increased accordingly. For example, in single-person driving, a collision speed of 40-50 km / h results in a Level 3 injury; a collision speed of 50-60 km / h results in a Level 2 injury; and a collision speed greater than 60 km / h results in a Level 1 injury, triggering the corresponding level of protective devices for enhanced protection. The higher the collision speed, the higher the injury level and the higher the protection level. When the collision speed remains constant, in two-person driving, the injury level is increased by one level.
[0033] S03, Protection Execution: Based on the possible collision landing point, the corresponding collision sensor is triggered to generate a trigger signal, which is then sent to the main control device via a signal line. After receiving the trigger signal, the main control device, in conjunction with the analyzed possible degree of injury, triggers the corresponding protective equipment to perform differentiated protection based on different collision types and degrees.
[0034] Specifically, the collision sensors include front, rear, left, and right side collision sensors, which correspond to and are triggered by the collision impact points on the front, rear, left, and right sides of the vehicle, respectively; the protective equipment includes on-board protective devices and wearable protective devices. The on-board protective devices may be front, rear, left, and right side airbags, corresponding to the front, rear, left, and right side collision sensors; the wearable protective devices include airbag-type protective equipment worn by the driver and passengers and helmets with positioning devices.
[0035] Based on the analysis of the potential injury level, corresponding protective equipment is triggered to provide differentiated protection according to different collision types and degrees. Specifically, when the analyzed potential injury level is level three, the on-board protection device is triggered, specifically the on-board protection device corresponding to the collision point location. When the analyzed potential injury level is level two or level one, both the on-board protection device and wearable protection device are triggered to enhance protection. Specifically, when the analyzed potential injury level is level two, the on-board protection device corresponding to the collision point location is triggered. When the analyzed potential injury level is level one, the on-board protection device corresponding to the collision point location and the collision point locations on both sides of the collision point is triggered, expanding the protection range of the protection device and improving safety protection.
[0036] For example, if the collision point is determined to be on the left side of the vehicle, and the potential injury level is Level 2, the left-side airbag and wearable protective device will be activated for protection. If the collision point is determined to be on the left side of the vehicle, and the potential injury level is Level 1, the left-side airbag, the airbags on both sides of the left side of the vehicle (front and rear), and the wearable protective device will be activated for protection. If the collision point is determined to be on the front of the vehicle, and the potential injury level is Level 2, the front-side airbag and wearable protective device will be activated for protection. If the collision point is determined to be on the front of the vehicle, and the potential injury level is Level 1, the front-side airbag, the airbags on both sides of the front side of the vehicle (left and right), and the wearable protective device will be activated for protection.
[0037] This embodiment also provides a collision protection system suitable for motorized two-wheeled vehicles, applying the above-described collision protection method for motorized two-wheeled vehicles, such as... Figure 3 As shown, it includes an electrically connected data acquisition end, analysis end, and execution end; The data acquisition terminal is used to collect collision data representing different collision types and different collision degrees; The analysis terminal is used to analyze the collision data to determine the location of the impact point and the possible degree of injury to the driver and passengers of the motorized two-wheeled vehicle. The execution end is used to trigger the corresponding collision sensor according to the possible collision landing point, generate a trigger signal, and send the trigger signal to the main control device through a signal line; after receiving the trigger signal, the main control device, in conjunction with the analyzed possible degree of injury, triggers the corresponding protective equipment to provide differentiated protection based on different collision types and different collision degrees.
[0038] Specifically, the data acquisition end can be configured using detection devices such as distance sensors, weight sensors, cameras, and positioning devices.
[0039] The specific usage process is as described above and will not be repeated here.
[0040] The collision protection method and system for motorized two-wheeled vehicles provided by this invention links the triggering of the protection device with the collision type and collision degree. It can predict the collision landing point and possible injury degree based on collision data, and trigger the corresponding protection device in a targeted manner to provide targeted protection measures for drivers and passengers, making the protection more reasonable.
