Technical Field

[0002] The present application relates to, but is not limited to, the field of automobile safety technology, and in particular to a device and method for reminding a deceleration signal for an automobile. Background Art

[0003] Rear-end collisions are inevitable when cars are driving. A rear-end collision is when two vehicles traveling in the same lane collide with each other.

[0004] In actual vehicle driving, rear-end collisions are likely to occur due to the following distance being less than the minimum safe distance and the driver's slow reaction. Summary of the Invention

[0005] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0006] The present invention provides a vehicle deceleration signal reminder device and method. The following describes various aspects of the present invention.

[0007] In a first aspect, the present application provides a deceleration signal reminder device for an automobile, comprising: a throttle signal detection unit, which generates a monitoring circuit connection signal in response to detecting that the automobile driver's foot has left the accelerator pedal; a signal sensing unit, which controls the real-time collection of the monitoring circuit connection signal; and a signal feedback unit, which controls the output of a deceleration signal based on the collected monitoring circuit connection signal to remind other vehicles.

[0008] In one embodiment of the present application, the throttle signal detection unit includes: a position detection mechanism, which is installed on the accelerator pedal and forms an attraction circuit when the foot leaves the accelerator pedal, generating a monitoring circuit connection signal; and an electrical signal output unit, which collects the monitoring circuit connection signal when the attraction circuit is formed and transmits it to the signal sensing unit.

[0009] In one embodiment of the present application, the throttle signal detection unit further includes: a vehicle speed monitoring unit, which monitors the vehicle speed signal when the vehicle is in an accelerating or constant speed state, and controls the start position detection mechanism according to the vehicle speed signal.

[0010] In one embodiment of the present application, the position detection mechanism is a position sensor.

[0011] In one embodiment of the present application, the position detection mechanism includes: an attraction circuit; and an attraction switch, wherein the attraction switch is electrically connected to the attraction circuit to disconnect the attraction circuit when the foot steps on the accelerator pedal, and connect the attraction circuit when the foot leaves the accelerator pedal.

[0012] In one embodiment of the present application, the signal sensing unit is an electrical signal sensor.

[0013] In one embodiment of the present application, the signal feedback unit includes: a deceleration signal transmitting unit, which controls the issuance of a deceleration signal for a deceleration reminder; and a signal output control unit, which is electrically connected to the deceleration signal transmitting unit to control the circuit closing and opening of the deceleration signal transmitting unit according to the monitoring circuit connection signal collected by the signal sensing unit.

[0014] In one embodiment of the present application, the signal output control unit is a relay.

[0015] In one embodiment of the present application, the deceleration signal transmitting unit is a deceleration signal light.

[0016] In a second aspect, the present application provides a deceleration signal reminder method applied to the aforementioned automobile deceleration signal reminder device, comprising:

[0017] Controlling a monitoring circuit that reflects changes in the accelerator pedal position when the foot is released from the accelerator pedal;

[0018] Collecting a monitoring circuit connection signal when forming a monitoring circuit;

[0019] According to the monitoring circuit connection signal, the control outputs a deceleration signal to alert other vehicles.

[0020] The present application provides a deceleration signal reminder device and method for an automobile. When an emergency situation requires deceleration or braking during vehicle travel, the device and method collects a signal when the foot is released from the accelerator pedal via a position detection mechanism. Based on the collected signal, the device controls the vehicle to output a deceleration signal to the following vehicle, enabling the following vehicle to promptly decelerate or brake upon receiving the deceleration signal. This increases the reaction time of the following vehicle before deceleration or braking, thereby reducing the incidence or severity of rear-end collisions. When the position detection mechanism collects the signal when the accelerator pedal is lifted, the accelerator pedal contacts the pull-in switch, forming a pull-in circuit between the pull-in circuit and the pull-in switch. Furthermore, a signal sensing unit collects a monitoring circuit connection signal when the pull-in circuit is formed, and a signal output control unit controls the deceleration signal transmitter to output a deceleration signal to alert the following vehicle. This deceleration signal reminder method ensures that the circuit for detecting the accelerator pedal position when the accelerator pedal is lifted and the circuit for generating the deceleration signal output operate independently and without interference. Moreover, when outputting a deceleration signal, the deceleration signal light outputs a clear warning color to prompt deceleration, which is easy to observe.

DETAILED DESCRIPTION

[0030] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0032] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0033] Rear-end collisions are common in the automotive industry. A rear-end collision occurs when two vehicles traveling in the same lane collide with each other. These collisions are primarily caused by following a vehicle below the minimum safe distance, slow driver reaction, or poor braking system performance.

[0034] In actual vehicle driving, for example, when the vehicle in front suddenly brakes, the vehicle behind brakes only after seeing the brake lights of the vehicle in front, which results in insufficient reaction time and insufficient braking distance, easily causing a rear-end collision.

[0035] In response to the above problem, please refer to Figure 1. The present application provides a deceleration signal reminder device for a car, including: a throttle signal detection unit 1, which generates a monitoring circuit connection signal in response to detecting that the car driver's foot leaves the accelerator pedal 4; a signal sensing unit 2, which controls the real-time collection of the monitoring circuit connection signal; and a signal feedback unit 3, which controls the output of a deceleration signal based on the collected monitoring circuit connection signal to remind other vehicles.

[0036] From the above, it is easy to see that during vehicle travel, when the driver needs to decelerate, their foot will first leave the accelerator pedal 4 and move to the brake pedal to apply braking measures. When the driver's foot leaves the accelerator pedal 4, the accelerator signal detection unit 1 is used to connect the monitoring circuit and generate a monitoring circuit signal when the foot leaves the accelerator pedal 4. Similarly, during acceleration or constant speed driving, the foot will always remain on the accelerator pedal 4. However, due to the foot's depressing of the accelerator pedal 4, the accelerator signal detection unit 1 is unable to generate a corresponding monitoring circuit connection signal. When the accelerator signal detection unit 1 detects the monitoring circuit connection signal, the signal sensing unit 2 receives the monitoring circuit connection signal from the accelerator signal detection unit 1 and quickly transmits it to the signal feedback unit 3. Based on the sensing signal (i.e., the monitoring circuit connection signal) from the signal sensing unit 2, the signal feedback unit 3 further controls the vehicle to output a deceleration signal to alert the following vehicle, indicating that the vehicle has released the accelerator pedal 4 and that the upcoming operation may be deceleration or braking. The deceleration signal can be a deceleration signal light, voice, text prompt, etc. Through the above method, it is achieved that before the vehicle decelerates or brakes, the accelerator is released (i.e., the foot leaves the accelerator pedal 4) to remind the following vehicle, which increases the reaction time given to the following vehicle before deceleration or braking. Specifically, before the vehicle decelerates or brakes, the foot will leave the accelerator pedal 4 and move towards the brake pedal. Under normal circumstances, the time it takes for the following vehicle to decelerate or brake in response to the same deceleration or braking action of the leading vehicle is the time it takes for the following vehicle to observe the braking reminder given by the leading vehicle (such as the brake signal light) and take action based on the braking reminder. In the present application, by issuing a deceleration reminder to the following vehicle as soon as the leading vehicle's foot leaves the accelerator pedal 4, the following vehicle can react earlier based on the deceleration signal when the leading vehicle's foot leaves the accelerator pedal 4. This increases the braking distance, avoids rear-end collisions, reduces the incidence of rear-end collisions, or mitigates the severity of rear-end collisions.

[0037] As shown in Figure 2, the throttle signal detection unit 1 includes: a position detection mechanism 11, which is installed on the accelerator pedal 4 and forms an attraction circuit when the foot leaves the accelerator pedal 4, generating a monitoring circuit connection signal; and an electrical signal output unit 12, which collects the monitoring circuit connection signal when the attraction circuit is formed and transmits it to the signal sensing unit 2.

[0038] In one embodiment of the present application, when the throttle signal detection unit 1 detects the monitoring circuit connection signal when the foot leaves the accelerator pedal 4, the position detection mechanism 11 is used to detect the action of the foot leaving the accelerator pedal 4. Specifically, when the foot leaves the accelerator pedal 4, the angle of rotation of the accelerator pedal 4 will change, that is, it will rotate counterclockwise from the direction in which the foot stepped on the accelerator pedal 4 and return to the original position. When returning to the original position, the position detection mechanism 11 will be triggered to form an attraction loop. After the attraction loop is formed, the electrical signal of the attraction loop (i.e., the monitoring circuit connection signal) is transmitted to the signal sensing unit 2 through the electrical signal output unit 12, and the signal feedback unit 3 is further controlled by the signal sensing unit 2 to send a deceleration signal to alert the rear vehicle. Specifically, the electrical signal output unit 12 is a signal transmission line.

[0039] The throttle signal detection unit 1 further includes a vehicle speed monitoring unit 13 , which monitors the vehicle speed signal when the vehicle is in an accelerating or constant speed state, and controls the start position detection mechanism 11 according to the vehicle speed signal.

[0040] In one embodiment of the present application, while the position detection mechanism 11 is used to detect the position of the accelerator pedal 4 before and after rotation, the vehicle speed monitoring unit 13 monitors vehicle speed changes in real time. Specifically, when a speed signal indicating acceleration or a constant speed is collected, the position detection mechanism 11 is activated to detect the position of the accelerator pedal 4. When the vehicle is stopped or parked, the position detection mechanism 11 is deactivated.

[0041] Optionally, the position detection mechanism 11 is a position sensor.

[0042] In one embodiment of the present application, a position sensor monitors the position change of the accelerator pedal 4 in real time and generates an electrical signal (i.e., a monitoring circuit on signal) when the foot leaves the accelerator pedal 4. The signal sensing unit 2 collects the monitoring circuit on signal in real time and, upon collecting the signal, controls the signal feedback unit 3 to output a deceleration signal to alert the following vehicle of the impending deceleration or braking action.

[0043] Furthermore, the position detection mechanism 11 includes: an attraction circuit 111; and an attraction switch 112, the attraction switch 112 is electrically connected to the attraction circuit 111 to disconnect the attraction circuit when the foot steps on the accelerator pedal 4, and connect the attraction circuit when the foot leaves the accelerator pedal 4.

[0044] In one embodiment of the present application, during the process of forming a pull-in circuit using the position detection mechanism 11, a circuit connection is established between the pull-in circuit 111 and the pull-in switch 112. Furthermore, when the accelerator pedal 4 is stepped on, the accelerator pedal 4 rotates and changes position. At this point, the pull-in switch 112 causes the pull-in circuit 111 to be disconnected, and no monitoring circuit on signal is generated. The vehicle may be accelerating or traveling at a constant speed at this time. Furthermore, since the pull-in circuit 111 is disconnected, the signal sensing unit 2 is unable to detect the monitoring circuit on signal, resulting in no deceleration signal and no need to alert the following vehicle. When the foot releases the accelerator pedal 4, i.e., when the accelerator pedal 4 returns to its original position, the vehicle may further decelerate or brake. The pull-in switch 112 contacts the accelerator pedal 4, which has returned to its original position, and closes the pull-in switch 112, thereby forming a pull-in circuit with the pull-in circuit 111 and generating a monitoring circuit on signal. The monitoring circuit connection signal is collected by the signal sensing unit 2, which controls the signal feedback unit 3 to output a deceleration signal to warn the following vehicle to slow down. Specifically, the pull-in circuit 111 can be a power supply circuit that is independently powered by a power supply or connected to the vehicle's power supply, and its electrical signal output end is electrically connected to the two ends of the pull-in switch 112. The pull-in switch 112 can be installed in the contact area corresponding to the return of the accelerator pedal 4 to its original position.

[0045] Optionally, the signal sensing unit 2 is an electrical signal sensor. This electrical signal sensor enables the position detection mechanism 11 to detect a change in the position of the accelerator pedal 4, i.e., a signal indicating that the accelerator pedal 4 has returned to its original position, when the foot leaves the accelerator pedal 4. This sensor collects the electrical signal from the accelerator pedal (i.e., a monitoring circuit on signal) when forming a pull-in circuit. This in turn controls the signal feedback unit 3 to output a deceleration signal to warn the following vehicle to slow down.

[0046] As shown in Figure 3, the signal feedback unit 3 includes: a deceleration signal transmitting unit 31, which controls the deceleration signal for issuing a deceleration reminder; and a signal output control unit 32, which is electrically connected to the deceleration signal transmitting unit 31 to control the circuit closing and opening of the deceleration signal transmitting unit 31 according to the monitoring circuit connection signal collected by the signal sensing unit 2.

[0047] In one embodiment of the present application, after the signal sensing unit 2 collects an electrical signal (i.e., a monitoring circuit connection signal), the signal feedback unit 3 is controlled to output a deceleration signal by first sending the signal to the signal output control unit 32. The signal output control unit 32 then controls the circuit of the deceleration signal transmitting unit 31 to be connected (closed), thereby enabling the deceleration signal transmitting unit 31 to output a deceleration signal to alert the vehicle behind. When the deceleration signal transmitting unit 31 is not issuing a deceleration signal, the signal output control unit 32 controls the circuit of the deceleration signal transmitting unit 31 to be disconnected. In other words, it controls the power on or off of the deceleration signal transmitting unit 31.

[0048] Specifically, the signal output control unit 32 is a relay.

[0049] It is worth noting that when the foot leaves the accelerator pedal 4, the position detection mechanism 11, that is, the position sensor, collects the signal when the accelerator pedal 4 returns to its original position. However, the voltage and current of the control circuit output by the relay to the deceleration signal transmitting unit 31 do not match the voltage and current detected by the position sensor. Therefore, when the foot leaves the accelerator pedal 4, the accelerator pedal 4 is lifted, and a closed circuit is formed by the position detection mechanism 11 alone, thereby generating an electrical signal (that is, a monitoring circuit connection signal) and being detected by the signal sensing unit 2. When the signal sensing unit 2 detects the electrical signal, it will further control the circuit closing and opening of the deceleration signal transmitting unit 31 through the signal output control unit 32, that is, the relay.

[0050] Furthermore, the deceleration signal transmitting unit 31 is a deceleration signal light.

[0051] In one embodiment of the present application, the deceleration signal light can be installed at the rear of the vehicle as part of the taillight system. To clearly distinguish the deceleration signal light from the brake signal light, the deceleration signal light can be defined with a distinctive warning color, distinguishing it from the colors already defined in existing vehicle lighting regulations. For example, a rose red can be used. The deceleration signal transmitter 31 can also have other structures to provide deceleration signal reminders. For example, a voice announcement device can be used to provide a deceleration signal reminder, or a display can be used to display a text message indicating deceleration, alerting vehicles behind to decelerate.

[0052] Please refer to Figure 4. This application provides a specific example of a deceleration signal reminder device for an automobile. By installing a position detection mechanism 11 on the accelerator pedal 4, it is achieved that when the foot leaves the accelerator pedal 4, that is, the accelerator pedal 4 is lifted, the accelerator pedal 4 will contact the position detection mechanism 11, or the position detection mechanism 11 detects a position change signal of the accelerator pedal 4 being lifted. Specifically, when detecting the position change signal, an attraction loop is formed by the position detection mechanism 11, and the monitoring circuit connection signal when the attraction loop is formed is sent to the signal sensing unit 2 through the electrical signal output unit 12, that is, the signal sensing unit 2 collects the monitoring circuit connection signal in the attraction loop. The signal sensing unit 2 then controls the deceleration signal transmitting unit 31 to output a deceleration signal through the signal output control unit 32. The deceleration signal transmitting unit 31 can be selected to light up or not light up in the form of two sets of deceleration signal lights to prompt the following vehicle to decelerate or brake accordingly.

[0053] Referring to Figure 5 , during vehicle acceleration or constant speed driving, the foot remains on the accelerator pedal 4. At this point, the position detection mechanism 11 is not in contact with the accelerator pedal 4, meaning it does not detect any position change signals from the accelerator pedal 4. This means the position detection mechanism 11 does not form a pull-in circuit. Consequently, the signal sensing unit 2 and the signal output control unit 32 do not control the deceleration signal transmitting unit 31, i.e., the deceleration signal light, to illuminate. This means the deceleration signal light is not illuminated.

[0054] Please refer to Figure 6. When an emergency occurs in front of the vehicle, the driver's foot needs to leave the accelerator pedal 4 and move to the brake pedal. In the process of the foot leaving the accelerator pedal 4, the accelerator pedal 4 is lifted to the original position, and when it reaches the original position, it will contact the position detection mechanism 11, that is, the position detection mechanism 11 detects the position change of the accelerator pedal 4. The position detection mechanism 11 forms an attraction circuit. The electrical signal output unit 12 transmits the monitoring circuit connection signal to the signal sensing unit 2. The signal sensing unit 2 further controls the deceleration signal transmitting unit 31 through the signal output control unit 32, that is, the deceleration signal light is turned on. Even if the deceleration signal light is in the lit state.

[0055] As shown in FIG7 , the present application also provides a method for reminding a deceleration signal for an automobile, comprising:

[0056] Controlling the formation of a monitoring circuit that reflects the change in the accelerator pedal position when the foot leaves the accelerator pedal 4;

[0057] Collecting a monitoring circuit connection signal when forming a monitoring circuit;

[0058] According to the monitoring circuit connection signal, the control outputs a deceleration signal to alert other vehicles.

[0059] In one embodiment of the present application, during the driving of the vehicle, for example, by stepping on the accelerator pedal 4, the vehicle is in a state of acceleration or constant speed. When an emergency situation occurs and deceleration or braking is required, the foot will leave the accelerator pedal 4, and the accelerator pedal 4 will automatically rebound. When the accelerator pedal 4 rebounds, a monitoring circuit capable of generating a monitoring circuit connection signal is formed by controlling the accelerator pedal 4 to return to its original position. By collecting the monitoring circuit connection signal when the monitoring circuit is formed, and based on the monitoring circuit connection signal, the vehicle is controlled to output a deceleration signal, for example, the deceleration signal light outputs a clear warning color to indicate deceleration, the vehicle outputs a voice broadcast that the vehicle is about to decelerate, and the rear display screen of the vehicle plays a text reminder of deceleration information, so that the rear vehicle can take timely deceleration or braking measures according to the deceleration signal. This reduces the incidence of rear-end collisions or reduces the severity of rear-end collisions.

[0060] In summary, the present invention utilizes a position detection mechanism 11 to collect signals when the foot is released from the accelerator pedal 4 during vehicle operation, and based on the collected signals, controls the vehicle to output a deceleration signal to the following vehicle. This allows the following vehicle to promptly decelerate or brake upon receiving the deceleration signal, thereby increasing the reaction time of the following vehicle before deceleration or braking, thereby reducing the incidence or severity of rear-end collisions. When the position detection mechanism 11 collects signals when the accelerator pedal 4 is lifted, the accelerator pedal 4 contacts the pull-in switch 112, thereby forming a pull-in circuit between the pull-in circuit 111 and the pull-in switch 112. Furthermore, the signal sensing unit 2 collects the monitoring circuit connection signal when the pull-in circuit is formed, and further controls the deceleration signal transmitting unit 31 to output a deceleration signal via the signal output control unit 32 to alert the following vehicle. This deceleration signal alerting method ensures that the circuit for detecting the position of the accelerator pedal 4 when the accelerator pedal 4 is lifted and the circuit for generating the deceleration signal output operate independently and without interference. Moreover, when outputting a deceleration signal, the deceleration signal light outputs a clear warning color to prompt deceleration, which is easy to observe. Therefore, the present application effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0061] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
