Description

Vehicle storm prevention device

The invention belongs to the field of vehicles, and particularly relates to a vehicle surge prevention device that accurately judges a driver's mistaken stepping on the accelerator and can immediately block a large amount of fuel supply to prevent the vehicle from rushing, thereby maintaining traffic safety.

Vehicle storm usually refers to the unintentional acceleration behavior that occurs when the car is stationary and ready to start. Because the vehicle storm is not the state expected by the driver, it often becomes the cause of a traffic accident.

The most common causes of vehicle rush are due to improper operation of the driver, because the accelerator pedal and the brake pedal of a general vehicle are usually arranged next to each other to facilitate the driver's control. When the driver is slightly inadvertent or nervous In the state, it is possible to accidentally step on the accelerator pedal when you want to brake, resulting in a sudden accident.

In order to avoid accidental impulses caused by improper operation, China ’s patent No. M425811 provides a patented design of “auto riot impulsive device”, which is provided with a sensing element at the dead point under the accelerator pedal operating stroke. A damper is arranged between the accelerator pedals, so that the sensing element of the inductive element ends after the accelerator pedal completely compresses the damper, the feedback control signal is connected to a controller, and the controller is connected to a line of computer, and future The detection signal from the sensor element instructs the trip computer to interrupt the fuel supply, so that the engine cannot obtain a large amount of fuel to suppress the occurrence of storms.

However, the design of the conventional patent is not proper, so the following problems still need to be resolved: 1. The conventional patent considers that the crash accident mainly comes from the driver's action of stepping on the brakes, which is different from the throttle when driving. The pedal will only be pressed lightly; so judge whether a rush occurs? The reason is that the accelerator pedal must be fully depressed to fully compress the damper; however, this test method is obviously not objective. Depending on the driver ’s body shape, experience, habits, and response, it is still possible to press the accelerator pedal without pressing it to the end. A rush accident occurred; conversely, the problem of vehicle stall caused by accidentally touching the damper due to pressing the accelerator pedal too deep during normal acceleration cannot be ruled out; 2. The conventional patent must be connected to the trip computer, so it needs The manufacturer of the driving computer cooperates, but the design of the driving computer of each brand is not the same, and the hardware and software configuration in the driving computer usually needs to match the vehicle model. It is not easy to change the design and it is difficult to require the full cooperation of the vehicle manufacturer. , So it's actually not feasible.

It can be seen that the conventional technology still has problems in preventing the induction or implementation of the vehicle's storm, rather than a good design, which needs to be overcome by the industry.

In view of the various problems generated by the conventional technology, the inventor of this case has been eager to improve and innovate. After years of painstaking and meticulous research, he finally successfully developed this vehicle storm prevention device.

The main object of the present invention is to provide a vehicle burst prevention device, which uses By sensing the time difference of the change in the accelerator pedal distance, judging whether the driver's stepping behavior is abnormal, you can accurately identify whether the driver has stepped on by mistake, and then performing anti-violent shock treatment, which can effectively reduce the occurrence of vehicle sudden shock.

Another object of the present invention is to provide a vehicle storm prevention device, which is designed without changing the main structure of the vehicle and without requiring a trip computer to cooperate, so the cost is low and the power is powerful.

It is still another object of the present invention to provide a vehicle storm prevention device, which is fast and easy to install, and whether a new car leaves the factory or an old car is maintained, a safety protection can be added in a short period of time, and traffic safety is greatly improved.

The invention provides a vehicle overburden prevention device, which includes an induction switch, a control unit, and a release unit.

The principle of the present invention is to sense the time difference between depression of the accelerator pedal by the induction switch, calculate the depression speed of the accelerator pedal, and compare it with a preset abnormal time. If the speed is faster than the abnormal time, the It was confirmed that the driver depressed the accelerator pedal to behave abnormally, and then issued an abnormal signal.

Therefore, the inductive switch device is used to sense the pedaling speed of the accelerator pedal of a vehicle. The inductive switch includes a plurality of inductive points, and the inductive points are distributed on the moving path of the accelerator pedal to obtain different values. The sensing point can detect whether there is an abnormality by detecting the time difference of the accelerator pedal.

The control unit is used to receive the abnormal signal from the inductive switch, and then sends a control signal to the brake that controls the engine's oil injection to intercept a large number of oil injection actions to limit the engine's power and prevent the vehicle from rushing.

When the brake cuts off a large amount of oil, it still maintains a small amount of oil to maintain the normal operation of the engine.

At the same time, the control unit is connected with a warning unit. When the control unit sends out a control signal, it also sends a warning signal to the warning unit to remind people to pay attention. The warning unit is mainly a horn, which can remind the driver or surrounding personnel to pay attention.

The release unit is installed on the gear lever to sense the gear position of the gear lever. The setting method of the present invention is to release the gear when the gear lever is in the P position (parking position) or N position (neutral position). The unit will send a release signal to the control unit to release the control signal and resume normal operation of the vehicle.

On the other hand, when the position of the gearshift lever is in the P or N position, the release signal sent by the release unit will make the control unit unaffected by the control signal, allowing maintenance or test personnel to step on the force. The accelerator pedal is used to test the performance of the engine.

Furthermore, the sensing point can be a mechanical, magnetic or optical sensor. The mechanical type will sense when it comes into contact with the accelerator pedal, and the optical type uses a non-contact method to perform the sensing function.

For different types of vehicles or the driver, the sensor switch can adjust the depression speed of the accelerator pedal detected when an abnormal signal needs to be issued.

Moreover, the warning unit may also be a light or other warning method, and is mainly the original equipment of the vehicle, or the warning unit may be additionally installed.

FIG. 1 is a block diagram showing the structure of a vehicle surge prevention device according to the present invention; and FIG. 2 is a schematic operation diagram of the vehicle surge prevention device.

In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

Please refer to FIG. 1 and FIG. 2. The present invention provides a vehicle surge prevention device, which mainly includes an induction switch 1, a control unit 2, and a release unit 3.

The sensor switch 1 is installed on an accelerator pedal 11 of a vehicle 100, and is used to sense the depression speed of the accelerator pedal 11 to determine whether there is an abnormality in the depression action of the accelerator pedal 11. If it is abnormal, an abnormal signal is issued.

The aforementioned basis for judging whether the abnormality occurs is to consider the cause of the storm. The main reason is that the driver 110 mistakenly depresses the accelerator pedal 11 as a brake, and the driver 110 must be a forceful rapid pedaling action when the brake pedal is pressed. , And the more nervous you step on the more nervous. Therefore, as long as the time difference between stepping on the accelerator pedal 11 is sensed by the induction switch 1, it is possible to effectively determine whether the driver 110 is abnormal in stepping on the accelerator pedal 11 and then take measures.

The structure of the induction switch 1 further includes a plurality of induction points 10, each of which is distributed on the active path of the accelerator pedal 11, and the elapsed time of the accelerator pedal 11 on the active path is recorded one by one, and then different The sensing point 10 detects the time difference between the accelerator pedal 11 and calculates the depression speed of the accelerator pedal 11 and compares it with a preset abnormal speed. If the speed is faster than the abnormal speed, the driver can be confirmed 110 stomp on the throttle The operation of the pedal 11 is abnormal, and an abnormal signal is further issued.

The induction point 10 may be a mechanical, magnetic or optical sensor. The difference is that the mechanical point is in contact with the accelerator pedal 11 to generate induction. The magnetic type is that the induction point 10 and the accelerator pedal 11 are magnetically attracted. The optical function is a non-contact method that uses the accelerator pedal 11 to block light to perform the sensing function.

In addition, depending on the type of the vehicle 100 or the operation mode of the driver 110, the time when the accelerator pedal 11 is used to determine whether it is a storm behavior may be slightly different, so the sensor switch 1 can be adjusted to be issued The depression speed of the accelerator pedal 11 is detected during the abnormal signal.

The control unit 2 is used to receive the abnormal signal from the inductive switch 1 and then send a control signal to the brake 12 that controls the oil intake of the engine 13; the brake 12 has an oil control motor. When controlling the signal, the brake 12 restricts the fuel injection action, that is, when the accelerator pedal 11 is generally depressed, a large amount of fuel should be performed to increase the power of the engine 13 and allow the vehicle 100 to accelerate. When receiving the control signal, it will cut off a large number of fuel injection actions, so that the power of the engine 13 can be restricted, the vehicle 100 cannot be accelerated normally, and the effect of preventing storms is achieved.

In addition, when the brake 12 cuts off a large amount of fuel, it will still leave small holes to facilitate a small amount of fuel. Because most of the actions of the vehicle 100 require the power of the engine 13, if the fuel is completely blocked, the engine will be caused. 13 flameout, on the contrary, will make the vehicle 100 uncontrollable, including braking, etc., but it will cause a safety hazard, so it is necessary to maintain a small amount of fuel injection to maintain the normal operation of the engine 13.

In addition to the control signal, the control unit 2 is connected with a warning unit 15, When the control unit 2 sends out a control signal, it also sends a warning signal to the warning unit 15 to remind people to pay attention; the warning unit 15 can be the original equipment of the vehicle 100, mainly a horn, which can remind the driver 110 or surrounding personnel , To reduce the occurrence of accidents; of course, the warning unit 15 may also be a light or other warning method, and the warning unit 15 may be additionally provided.

The release unit 3 is installed on the gearshift lever 14 to sense the gear position of the gearshift lever 14. The setting method of the present invention is when the gearshift lever 14 is in the P position (parking position) or N position (neutral position). When in the position, the release unit 3 will send a release signal to the control unit 2 to release the control signal and resume normal operation of the vehicle 100.

The principle of lifting the control signal in the present invention is that when the driver 110 is aware of his abnormal behavior, he will inevitably stop the vehicle 100 first for treatment, and therefore the position of the gearshift lever 14 will be switched to P position or The N position, which indicates that the dangerous state has been lifted, and the normal state of the vehicle 100 can be restored.

In another case, when the position of the gearshift lever 14 is in the P position or the N position, the release signal issued by the release unit 3 will cause the control unit 2 to release the control signal and the brake 12 will work normally. It is at this time that stepping on the accelerator pedal 11 does not drive the vehicle 100 to travel. On the other hand, maintenance or test personnel may be allowed to step on the accelerator pedal 11 to test the performance of the engine 13.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should all be covered by the scope of patent application of the present invention. Within the scope of protection.
