Description

200538326 V. Description of the invention (1) '[Technical field to which the invention belongs] The present invention is a vehicle-specific collision avoidance early warning and defense system, which uses a radar sensor's induction detection and a CPU's central processing unit to calculate and compare At the same time, a warning can be displayed on the display or the brakes can be activated in time to compare the automatic braking deceleration or start the airbag in the bumper and the airbag in the car and restrain the seatbelt to achieve the purpose of anti-collision warning and protecting the safety of personnel in the car. [Technology] The concept of airbags proposes that when a car is received or biased, but the driver hits the passenger inside the car and the driver is injured, if the car will appear an inflatable and the passenger ’s injury-free will be confirmed by experiments, safety is fully guaranteed, so the United States The full airbags of cars that will be launched after the year roughly include three Crash Sensors. : Package) ° III. The airbag module consists of a full airbag and an outer cover that collide with the vehicle

The earliest Americans] 〇 | 1111161: 1 ^ (1 When a collision occurs in 1953, the car will stop due to a strong impact and the passenger often rushes forward due to inertia, such as a disk or other equipment. As a result, when the driver and passengers are impacted, they can buffer the driver and passengers before the driver and passengers to protect the driver and passengers. The driving rate will be greatly improved. It has been proved that the airbag can indeed provide the driver and passengers with The Life Safety Council passed the FMVSS208 Act, which stipulates that the airbag system must be installed in the driver's seat at the center of the heart. Install a basic component. I. The collision sensor (The I. The detection device (The Diagnostic module) Air Bag Assemblies). Its sir metal can or inflating device and a woven fabric are made of 'inflating devices containing chemicals, which can be selectively pyrolyzed during the formation, and quickly form gas after pyrolysis.

It is full of airbag passengers who are able to analyze and tie in the car while avoiding the tension of the followers. The car, gear, or a few meters down the entire airbag. The safety of the airbag safety model of the vehicle can be compared with the safety of the vehicle. If the safety can be greatly controlled, there is no even a gear, and the vehicle's full airbag hits the head with a very short head. The type of this module is that the full airbag of the bumper can be connected to the belt, which will reduce the occurrence of the car. Only when driving and braking can it be more automatic, making the airbag instantly balloon like a balloon, and it will explode in time. It is a balloon-like way to block the driving f to the front and protect the driver and passengers from the impact of the impact force by the collision sensor. It is a safety measure developed after the impact of the vehicle in a passive situation. An airbag is additionally installed, and the airbag and the seat belt can be exploded immediately before or immediately after the collision through the central processing unit of the CPU, which can not only greatly reduce the force of the vehicle being impacted, but also impact by internal personnel. The damage to the front can even be avoided. The traditional braking system is operated by driving. In an emergency, it is usually because of the driver's failure or because of a short period of time that it is impossible to immediately control the owner due to excessive nervousness. The brake gear is a consequence of serious forward movement. If the brake can be decelerated before the collision or chase, it will greatly reduce the probability of a collision or chase.Based on the existing anti-collision systems and structures of the above vehicles, we can summarize them as follows: (a) Preventive aspects: The airbags and seatbelts of the traditional anti-collision systems are burst and tightened after the vehicle has chased. Occurs instantaneously, and operates completely in a passive situation, that is, in a passive state, it protects the driver and passengers.

200538326 V. The action of invention description (3); Similarly, the current car brake system also depends on the driver's control to perform its proper function, that is, the operation of the car driver can only be produced under the control of the driver. The external braking system, since it can only act in a passive situation, and the reason for ordinary traffic accidents, is that most of them are caused by the car driver's delay or emergency braking. The preventive effect can only be performed in a safety mode, and in a real emergency, it is helpless, so there is no substantial preventive function at all. (b) · Reasonableness: As the vehicle was hit and the passengers and passengers were masses, the body of the car must be the first and it is not normal. The inner body of the car, but the car exploded and was full. Out of the ordinary, tradition

The airbag and seatbelt of the traditional anti-collision system can only be effective under the condition of 4 or strong external force. 2 Since the vehicle has been chased, although the person (driving) in the vehicle is still a short distance from the front and rear of the vehicle Distance, but because the car body is all made of hard, even the bumper is directly fixed to the car body, there is no such thing as shock absorption or anti-impact device design, old people who are flesh and blood are not at all It ’s impossible to be hurt if you are hurt | Reason ^ There is a risk of putting the cart before the horse. In more detail, the queen ’s oxygen bladder bursts when the vehicle hits, and the seat belts tighten the people in the car. Forward rush, if the action is tied tightly, although it has a mode of operation that protects the life of the personnel in the car before bursting and tightening, it will explode on its own when the knife is struck before the impact, and restrain the seat belt. The model must be in shape, and its protection and protection effect will be greatly reduced, due to the explosion of the airbag of the anti-collision system and the tightening of the seat belt.

Page 6 200538326 V. Description of the invention (4) The mode will be classified as (c) • The safety side of the vehicle will act as a restraint when the situation occurs or the sensitivity of the respected personnel will try to prevent the unfortunate occurrence or all moments except tension. This is how the safety aspect is generated. [Invention Summary] On the conventional side: After the impact, it protects all the instantaneous reactions and accidents. Basically, it is doubtful that the design is inferior. 'The airbags in the car only exploded and the safety of the personnel in the car was caused by the seatbelts. Whenever there is a situation between emergencies, it is necessary to rely on the hands and feet of the car to control the car's braking system. It shows that in the event of an emergency situation, most drivers have no time to respond, and the occurrence of accidents also includes the lack of airbags and braking systems of the collision prevention system. Yes, the traditional anti-collision system has the above-mentioned problems. The inventor of the present case is that the airbag and automatic brake and booster are additionally installed in the bumper of the vehicle. The airbag and automatic brake assist are all controlled by the CPU. The control of the device is based on the induction detection of the radar sensor and the calculation analysis of the CPU. After the warning is displayed on the display or the brake assist is activated, the brake is automatically decelerated or the safety inside the bumper is activated. The airbag and the airbag in the car also restrain the seatbelt, so as to achieve the purpose of early warning and defense of the vehicle's defense ability and to protect the safety of the personnel in the car. On the basis of the above-mentioned reasonable automatic braking adjustment of vehicle speed and safety distance, the applicant still hopes to achieve a previously preventive and reasonable control system through a combination of a CPU central processing unit, a radar sensor, and an automatic braking assistant. And security requirements, but ownership in the control system

200538326 V. Description of the invention (5) The adjustment of the function does not currently have a system. Therefore, the wrong trial method must be adopted, which is time-consuming and labor-intensive, and may not achieve the expected results. Nowadays, the academic community has proposed an adaptive control system that can learn and adjust as the system characteristics change. For example, Jang's adaptive network inference control system (ANFIS) (see IEEE Transaction on System, Men and Cybernetics, May 1993, 66 pages 5 to 68 5). This system can realize the functions of non-linear followability control, dynamic system identification and adaptive signal processing. The so-called safe vehicle distance is the shortest distance that can be safely braked to avoid danger in the event of an accident ahead. As shown in Figure 1, the optimal safety distance of the vehicle collision control system is set. For the time ^ = car, half of the value. In principle, the central processing of this system's CPU = Tian takes the safety distance required by traffic regulations as a warning standard, but it can also be used to switch the switch to make it safe for low or traffic jams === to the current vehicle speed The value is one-third or one-fifth. The bursting point of the two full airbags and the reference point of the seat belt restraint are set at 30-50 cm or 0.005_3 seconds before the collision. [Content of the Invention] The radar two sensors use a frequency-modulated continuous wave (FMCW) setter. The sensors are at least relative to each other at the four sides of the vehicle, and are separated by f and inductive @ Ϊ 探 _ 至, j's seat library Analyze the t-speed and other data with the former or the target vehicle as the CPU central processor to calculate the vehicle speed. The car is at the center of Γυ. The timing is controlled by the automatic brake assist. Automatic brake assist, one

200538326 V. Description of the invention (6) This system is a vehicle-specific anti-collision early warning and defense system. Its main components include a radar sensor (1), a switch (2), a CPU central processing unit (3), and a warning display (4). ), Automatic brake assist (5) and safety control (6) 'as shown in Figure 2, where the safety control device (6) includes two parts, such as a safety bag (60) and a safety belt (61), such as Figure 3 shows. The airbag (60) is divided into two devices: the airbag (600) in the bumper and the airbag (= 1) in the seat. The airbag (600) in the bumper is effective. ^ Impact force It is designed with the airbag (601) and safety

: · When the two belong to the same control system and act at the same time, the distance between the forklift of the seat car exceeding the warning range and the safe starting point (about 3; within the range of the male knife, or 0.05 to 3 seconds before the collision) Within seconds), the ϊ ϊ 卩 in the CPU lever is executed by the safety control device (6) and starts the lice (600) such as the insurance (61) and the airbag (601) and seat belt in the seat car. Full airbag irn; make the airbag (600) in the bumper and the safety in the seat car reduce the impact of the car i when the two hit, and simultaneously restrain the seat belt (61),-effective protective measures, as far as possible Possibly let the car :: members within the crew do the best goal without any injuries. To avoid injury by flesh, even [Embodiment] First, infer the four basic cars in simulation to the figure shown.

Page 10 V. Description of the invention (8) At this time, the purpose of setting the system is to start, through the operation of the safety control device (6), start and burst the airbag (600) in the bumper and the seat. The airbag (601), and the restraint seat belt (60), by bursting the air Ϊ (61〇) and the airbag (6〇1) and the beam in the seat car, the seat car was hit by an accident The degree of force loss, etc. is reduced to a minimum, and even the relative distance without any of the above is explained by the absolute distance of the flow to the fixed object, let's take the example of the earthen vehicle. The fixed object or the obstacle is called immobile ^ Due to the operation of this system, whether the vehicle is moving forward or backward, etc., the distance generated by a fixed object at a certain position is the absolute distance, and only the vehicle is the control of the change of fixed objects or obstacles. Therefore, since it is an absolute distance, the front detected by all radar sensors (1) is more suitable for the operation of this system; according to the warning standard set by the CPU central processor to calculate the distance of the target behind the lice Within value, then Following the 77-level comparison, if "not in line with" is set, the warning display (4) shows that the distance is normal, and if "in line with", the banner or the buzzer will be issued at the same time, and or At the same time, a warning is displayed, and the car and the target in front or behind are two tones, etc. to remind the driver to note that if the car is lowered by itself, the distance between the seat and the seat is at this time. When the driver is out of the warning range, Then the distance between the factory and the target is widened and it returns to the normal operating condition, but when the display (4) is turned off, all the distances continue to get closer and enter and merge, and the obstacles in front or behind In the case of temporary conditions, automatic braking is performed through the implementation of w (5) in the stage (automatic braking range):

200538326 V. Description of the invention (9) The vehicle slowly reduces the speed until the distance between the seat vehicle and the obstacle is far from the automatic braking range (that is, the standard value of the safe vehicle distance), at this time everything is again; = normal operating condition When encountering such a phenomenon, such as parking on the side of the road or driving in narrow lanes or traffic jams, etc., the driver can switch to a lower standard value by switching the switch (丨) to make the system work. The data was reduced to meet the needs of the situation. And if unfortunately the car and the front obstacles, or the rear, left and right side obstacles and the car are close to collide, at this time, the setting function of this system will be activated. Explode the airbag (600) inside the bumper and the airbag (601) inside the lever, and restrain the seatbelt (61), by exploding the airbag (600) inside the lever and The airbag (601) and the text belt (6 1) in the seat car are triple-acted at the same time, which can minimize the degree of injury to the personnel in the car after the collision with the helmet, even to the least extent. The purpose of anti-collision warning and defense and protecting the personnel in the car is summarized. Although this system does not dare to call itself the invention of the top, the effectiveness of ί = really has the ability to prevent and defend the vehicle. Auxiliary devices to assist drivers in admiring vehicles include: Progressive cars; Γ in the best state, 'the umtr invention of this system' and 'practicalness granting appropriation to the special spear Milwenti stomach and bureau review and approval , And look forward to the early "in the development of the AirPlus inventor's painstaking efforts", please everyone deserve
