[0002] With the continuous development of science and technology, vehicle braking devices have emerged. At present, when the vehicle braking device detects that the distance between the vehicle and the front dangerous obstacle reaches the minimum safety distance in real time, the driver is reminded to brake through an alarm. However, when the driver receives the alarm signal, the distance between the vehicle and the front dangerous obstacle is short, and the user is prone to not braking in time due to a short braking reaction time, or not normally engaging the gear due to panic, thereby reducing the safety of driving. SUMMARY

[0003] The main purpose of the present application is to provide a vehicle braking method, device, electronic device, and readable storage medium, which aims to solve the technical problem of low driving safety in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides a vehicle braking method applied to a target vehicle, which comprises the following steps:

[0005] If it is detected that a preset braking device of the target vehicle is in an activated state, the distance between the target vehicle and an obstacle is detected to obtain a first interval distance;

[0006] If the first interval distance is within a preset first distance limit value, the target vehicle is controlled to send a braking warning signal, wherein the preset first distance limit value is used to ensure the safety of vehicle driving when the user manually brakes;

[0007] If the first interval distance is within a preset second distance limit value, the target vehicle is controlled to brake, wherein the preset second distance limit value is used to ensure the safety of vehicle driving when the vehicle automatically brakes;

[0008] The preset first distance limit value is greater than the preset second distance limit value.

[0009] To achieve the above-mentioned purpose, the present application further provides a vehicle braking device applied to a target vehicle, which comprises the following steps:

[0010] A parameter acquisition module is configured to detect the distance between the target vehicle and an obstacle to obtain a first interval distance if it is detected that a preset braking device of the target vehicle is in an activated state;

[0011] The manual braking module is configured to control the target vehicle to send a braking warning signal if the first interval distance is within a preset first distance limit value, wherein the preset first distance limit value is configured to ensure vehicle driving safety when the user manually brakes.

[0012] The automatic braking module is configured to control the target vehicle to brake if the first interval distance is within a preset second distance limit value, wherein the preset second distance limit value is configured to ensure vehicle driving safety when the vehicle automatically brakes; and the preset first distance limit value is greater than the preset second distance limit value.

[0016] The application provides a vehicle braking method, device, electronic equipment and readable storage medium. Compared with the technical means that a vehicle braking device in the prior art reminds a driver to brake through an alarm when it is detected that the distance between the vehicle and a front dangerous obstacle reaches a minimum safety distance, the application detects the distance between the target vehicle and the obstacle if the preset braking device of the target vehicle is in an activated state, and obtains a first interval distance. If the first interval distance is within a preset first distance limit value, the target vehicle is controlled to send a braking warning signal, wherein the preset first distance limit value is used to ensure the vehicle driving safety when the user brakes manually. If the first interval distance is within a preset second distance limit value, the target vehicle is controlled to brake, wherein the preset second distance limit value is used to ensure the vehicle driving safety when the vehicle brakes automatically. The preset first distance limit value is greater than the preset second distance limit value. In the process of completing the braking of the target vehicle, the application divides the process into a manual braking stage and an automatic braking stage. First, in the manual braking stage, the user is reminded to brake through the braking warning signal. If the user does not complete the braking in the manual braking stage, the automatic braking stage is entered, and the vehicle braking device automatically triggers the braking operation to control the target vehicle to complete the automatic braking, so that the target vehicle brakes under the control of the two stages, the target vehicle can complete the braking within the minimum safety distance, and the technical defects that the driver is prone to brake not in time due to short braking reaction time or abnormal gear shifting behavior due to panic when receiving the alarm signal in the prior art are overcome, and the driving safety is improved.

[0024] In order to make the above object, features and advantages of the present application more apparent, clear and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0025] Embodiment one

[0026] The present application provides a vehicle braking method, in the first embodiment of the clutch closing control method of the present application, applied to a target vehicle, referring to Figure 1 , the vehicle braking method comprises:

[0027] Step S10, if the preset braking device of the target vehicle is in an activated state, detecting the distance between the target vehicle and the obstacle to obtain a first interval distance;

[0028] In the present embodiment, it should be noted that the preset braking device is provided with a preset alarm limit value and a preset emergency braking limit value, the first interval distance is the real-time straight line distance between the target vehicle and the obstacle, and the distance detection method is to use a radar ranging sensor to detect.

[0029] In addition, it should be noted that the working principle of the radar ranging sensor is that the controller controls the radar ranging sensor to emit an ultrasonic signal, when the ultrasonic signal encounters an obstacle, a return signal is generated, the radar ranging sensor receives the return signal and processes the data through the controller to determine the position of the obstacle, thereby obtaining the distance between the obstacle and the vehicle.

[0030] As an example, step S10 comprises: sending a detection signal by the controller to detect whether the preset braking device of the target vehicle is in an activated state; if the preset device of the target vehicle is in the activated state, acquiring a first interval distance between the target vehicle and an obstacle by a radar ranging sensor; if the preset braking device of the target vehicle is not in the activated state, continuously monitoring whether the preset braking device of the target vehicle is activated. The obstacle can be any object that affects the driving of the vehicle, including moving obstacles and stationary obstacles, such as pedestrians, stationary telegraph poles, stationary trash cans, other vehicles, etc.

[0031] Step S20, if the first interval distance is within a preset first distance limit value, controlling the target vehicle to issue a braking warning signal, wherein the preset first distance limit value is used to ensure the driving safety of the vehicle when the user manually brakes.

[0032] In this embodiment, it should be noted that the preset first distance limit value is a preset warning limit value, which is used to ensure the driving safety of the vehicle when the user manually brakes, and the braking warning signal can be an image text prompt signal or an audible and visual alarm signal.

[0033] As an example, step S20 comprises: acquiring a preset first distance limit value, determining whether the first interval distance is within the preset first distance limit value; if the first interval distance is within the preset first distance limit value, controlling the target vehicle to issue a braking warning signal to remind the people in the vehicle to brake; if the first interval distance is not within the preset first distance limit value, continuously monitoring whether the first interval distance is within the preset first distance limit value. For example, it can be assumed that the preset first distance limit value is 20, and the interval distance between the target vehicle and the obstacle at this time is 18. It can be seen that 18<20, that is, the first interval distance is within the preset first distance limit value, and at this time the preset braking device of the target vehicle controls the target vehicle to issue an alarm signal to remind the people in the vehicle to brake.

[0034] Step S30, if the first interval distance is within a preset second distance limit value, controlling the target vehicle to automatically brake, wherein the preset second distance limit value is used to ensure the driving safety of the vehicle when the vehicle automatically brakes; and the preset first distance limit value is greater than the preset second distance limit value.

[0035] In this embodiment, it should be noted that the preset second distance limit value is a preset emergency braking limit value, which is used to ensure the driving safety of the vehicle when the vehicle automatically brakes.

[0036] As an example, step S30 comprises: obtaining a preset second distance limit value, judging whether the second interval distance is within the preset second distance limit value; if the second interval distance is within the preset second distance limit value, triggering the braking operation of the vehicle braking device, and controlling the target vehicle to complete automatic braking; if the second interval distance is not within the preset second distance limit value, continuously monitoring whether the second interval distance is within the preset second distance limit value. For example, it can be assumed that the preset second distance limit value is 10, and at this time the second interval distance between the target vehicle and the obstacle is 9, it can be seen that 9<10, that is, the second interval distance is within the preset second distance limit value, and the vehicle braking device will automatically trigger braking to control the target vehicle to complete automatic braking.

[0037] In the step of detecting the distance between the target vehicle and the obstacle to obtain the first interval distance, the vehicle braking method further comprises:

[0038] Step S11, calculating the difference between the first interval distance and the preset first distance limit value to obtain a displacement difference;

[0039] Step S12, obtaining the maximum acceleration of the target vehicle, and determining the running speed limit value of the target vehicle according to the displacement difference and the maximum acceleration;

[0040] In this embodiment, it should be noted that the running speed limit value is the maximum running speed of the target vehicle after the preset braking device of the target vehicle is activated. The running speed limit value will be adjusted in real time according to the distance between the target vehicle and the obstacle.

[0041] As an example, steps S11 to S12 comprise: subtracting the first interval distance from the preset first distance limit value to obtain a displacement difference; obtaining the running speed of the target vehicle and the power change of the target vehicle, calculating the maximum acceleration of the target vehicle according to the running speed of the target vehicle and the power change of the target vehicle; and calculating the running speed limit value of the target vehicle according to the displacement difference and the maximum acceleration, wherein the final speed is zero by default when calculating the running speed limit value of the target vehicle. For example, it can be assumed that the displacement difference is 50 m, the maximum acceleration is 4 m / s 2 , and the running speed limit value is calculated to be 20 m / s according to the calculation formula of acceleration and displacement difference.

[0042] As an example, the maximum acceleration of the target vehicle is calculated as follows:

[0043] a=ΔP / (mV)

[0044] Wherein, a is the maximum acceleration of the target vehicle, ΔP is the power change of the target vehicle, m is the mass of the target vehicle, and V is the speed of the target vehicle when running at a constant speed.

[0045] As an example, the running speed limit value of the target vehicle is calculated as follows:

[0046] V t 2 = 2as

[0047] Wherein, V t is the running speed limit value of the target vehicle, a is the maximum acceleration of the target vehicle, and s is the displacement difference.

[0048] Step S13, obtaining the running speed of the target vehicle, and judging whether the running speed is within the running speed limit value according to the running speed and the running speed limit value;

[0049] Step S14, if yes, maintaining the running speed of the target vehicle;

[0050] Step S15, if no, adjusting the running speed of the target vehicle.

[0051] As an example, steps S13 to S15 include: obtaining all wheel speeds of the target vehicle, performing average weighted processing on the all target wheel speeds to obtain the running speed of the target vehicle; judging whether the running speed is within the running speed limit value according to the running speed and the running speed limit value; if the running speed is within the running speed limit value, maintaining the running speed of the target vehicle; and if the running speed is not within the running speed limit value, adjusting the running speed of the target vehicle until the running speed is within the running speed limit value.

[0052] The step of adjusting the running speed of the target vehicle includes:

[0053] Step S151, obtaining the current speed of the target vehicle, and generating a speed control signal according to the current speed of the target vehicle and the running speed limit value;

[0054] Step S152, performing speed reduction processing on the current speed of the target vehicle according to the speed control signal to obtain an adjusted running speed.

[0055] As an example, the step S151 to the step S152 include: acquiring all wheel speeds of the target vehicle, performing average weighting processing on the all target wheel speeds to obtain a current rotating speed of the target vehicle; generating a speed control signal according to the current rotating speed and the running speed limit value; and controlling the target vehicle to reduce speed according to the speed control signal until the current rotating speed of the target vehicle is within the running speed limit value, and then stopping the speed control to obtain an adjusted running speed. If there is a wheel speed with a large numerical difference in the all wheel speeds, the wheel speed with the large numerical difference can be discarded so as not to participate in the vehicle speed calculation. The embodiment of the application can adjust the running speed of the target vehicle to be within the running speed limit value, so as to avoid the situation that the target vehicle cannot remain stationary within the interval distance of the target vehicle and the obstacle due to the too long time required for the target vehicle to decelerate to zero after completing the brake operation, and the target vehicle collides with the obstacle.

[0056] After the step of controlling the target vehicle to automatically brake, the vehicle brake method further includes:

[0057] In the step S31, if it is detected that the target vehicle completes the automatic brake of the vehicle, the distance between the target vehicle and the obstacle is detected to obtain a second interval distance, wherein the target vehicle is in a locked state after completing the automatic brake of the vehicle.

[0058] In the embodiment, it is to be noted that the second interval distance is the distance between the target vehicle and the obstacle after the target vehicle is in the locked state; and the locked state of the target vehicle refers to the stationary state of the target vehicle.

[0059] In the step S32, if the second interval distance is within the preset second distance limit value, it is detected whether the user performs a manual cancel brake or gear shifting operation.

[0060] In the step S33, if yes, the locked state of the target vehicle is released.

[0061] As an example, steps S31 to S33 include: after detecting that the target vehicle completes vehicle automatic braking and the vehicle is in a locked state, obtaining a second interval distance between the target vehicle and the obstacle through a radar ranging sensor; if the second interval distance is within the preset second distance limit value, detecting whether the user performs a manual cancel vehicle braking or gear shifting operation; if it is detected that the user performs a manual cancel vehicle braking or gear shifting operation, the locked state of the target vehicle is released, and the vehicle can continue normal driving; if it is not detected that the user performs a manual cancel vehicle braking or gear shifting operation, the locked state of the target vehicle is maintained. For example, it can be assumed that the preset second distance limit value is 10, and the second interval distance is 5. Since 5<10, the user needs to perform a manual cancel vehicle braking or gear shifting operation to release the locked state of the target vehicle. The embodiment of the present application can avoid the situation that the target vehicle collides with the obstacle due to the fact that the user does not properly take over the target vehicle, causing the target vehicle to start again.

[0062] The present application provides a vehicle braking method, device, electronic equipment and readable storage medium. Compared with the technical means in the prior art that the vehicle braking device reminds the driver to brake through an alarm when it is detected in real time that the distance between the vehicle and the front dangerous obstacle has reached the minimum safety distance, if it is detected that the preset braking device of the target vehicle is in an activated state, the distance between the target vehicle and the obstacle is detected to obtain a first interval distance; if the first interval distance is within a preset first distance limit value, the target vehicle is controlled to issue a braking warning signal, wherein the preset alarm limit value is used to ensure the vehicle driving safety when the user manually brakes; if the first interval distance is within a preset second distance limit value, the target vehicle is controlled to brake, wherein the preset emergency braking limit value is used to ensure the vehicle driving safety when the vehicle automatically brakes; and the preset first distance limit value is greater than the preset second distance limit value. The present application divides the process of completing the braking of the target vehicle into two stages, i.e., a manual braking stage and an automatic braking stage. First, in the manual braking stage, the user is reminded to brake through a braking warning signal. If the user does not complete braking in the manual braking stage, the automatic braking stage is entered, and the vehicle braking device automatically triggers the braking operation to control the target vehicle to complete automatic braking, so that the target vehicle brakes under the control of the two stages, ensures that the target vehicle can complete braking within the minimum safety distance, overcomes the technical defects in the prior art that the driver is prone to braking not in time due to short braking reaction time or abnormal gear shifting behavior due to panic when receiving the alarm signal, and improves the driving safety.

[0063] Embodiment Two

[0064] Further, with reference to Figure 2 In another embodiment of the present application, the same or similar content as Embodiment One can be referred to the above description, and will not be repeated hereinafter. Before the step of detecting that the preset brake device of the target vehicle is in an activated state, the vehicle braking method further comprises:

[0065] Step S101, obtaining sound information of an in-vehicle person of the target vehicle, wherein the sound information at least includes one of sound decibel size and voice command;

[0066] Step S102, judging whether to activate the preset brake device according to the sound information.

[0067] As an example, steps S101 to S102 include: obtaining sound information of an in-vehicle person, judging whether to activate the preset brake device according to the sound information; if the sound decibel size in the sound information is greater than a preset sound decibel size limit value, or the recognition result of the voice command in the sound information is a brake command, then the preset brake device is activated. Wherein the sound information of the in-vehicle person at least includes one of sound decibel size and voice command, when one kind of sound information reaches the activation condition, the preset brake device will be activated. For example, it can be assumed that the current sound decibel size is greater than the preset sound decibel size limit value, and the recognition result of the voice command is not a brake command, at this time one kind of sound information reaches the activation condition, then the preset brake device is activated.

[0068] Wherein, the step of judging whether to activate the preset brake device according to the sound information comprises:

[0069] Step A10, judging whether the sound decibel size is greater than a preset sound decibel size limit value;

[0070] Step A20, if yes, then activating the preset brake device;

[0071] Step A30, if no, then not activating the preset brake device.

[0072] In the embodiment, it is to be explained that the sound decibel size can be measured by an integrating sound level meter, wherein the working principle of the integrating sound level meter is that a microphone converts a received sound signal into an electric signal, the electric signal is converted impedance by a preamplifier so that the microphone is matched with an attenuator. An amplifier adds an output signal to a weighting network to perform frequency weighting (or an external filter) on the output signal, and then the output signal is amplified to a certain amplitude by an attenuator and an amplifier, and is sent to an effective value detector (or an external level recorder), and a noise level value is given on an indicator head, so that the sound decibel size is obtained.

[0073] As an example, the steps A10 to A30 include: obtaining a preset sound decibel size limit value in the preset braking device, wherein the preset sound decibel size limit value is a minimum value of the sound decibel of the activated preset braking device; if the sound decibel size is greater than the preset sound decibel size limit value, the preset braking device is activated; and if the sound decibel size is not greater than the preset sound decibel size limit value, the preset braking device is not activated. For example, it can be assumed that the preset sound decibel size limit value is 100 dB, and the detected sound decibel size is 110 dB, and since 110 dB > 100 dB, the preset braking device is activated.

[0074] The step of judging whether to activate the preset braking device according to the sound information includes:

[0075] Step B10, judging whether the voice recognition result of the voice command is a brake command;

[0076] Step B20, if yes, activating the preset braking device;

[0077] Step B30, if no, not activating the preset braking device.

[0078] As an example, the steps B10 to B30 include: identifying the voice command by using a voice recognition technology, obtaining the voice recognition result of the voice command, judging whether the voice recognition result is a brake command; if the voice recognition result is a brake command, the preset braking device is activated; and if the voice recognition result is not a brake command, the preset braking device is not activated. For example, it can be assumed that the current vehicle occupant speaks a voice command containing a brake request, the voice command is extracted by using a voice recognition technology, and the obtained text information contains the word "brake", so the system identifies this voice command as a brake command, and thus the preset braking device is activated.

[0079] The embodiment of the application provides a kind of activation method of vehicle brake device, that is, by obtaining the sound information of the personnel in the target vehicle, wherein the sound information at least includes one of sound decibel size and voice command;According to the sound information, it is judged whether the preset brake device is activated.The embodiment of the application identifies the need of emergency braking of vehicle by the sound information of the personnel in the vehicle, so as to activate the vehicle brake device, so that the vehicle brake device can assist the vehicle to travel in advance, compared with the way of activating the vehicle brake device by the obstacle outside the vehicle, the situation of activating the vehicle brake device is added, so as to increase the driving safety level.

[0082] Parameter acquisition module 10B is used to detect the distance between the target vehicle and the obstacle if the preset brake device of the target vehicle is in activated state, and obtain the first interval distance;

[0083] Manual brake module 20B is used to control the target vehicle to issue brake warning signal if the first interval distance is within preset first distance limit value, wherein the preset first distance limit value is used to ensure the vehicle driving safety when user manually brakes;

[0084] Automatic brake module 30B is used to control the target vehicle to brake if the first interval distance is within preset second distance limit value, wherein the preset second distance limit value is used to ensure the vehicle driving safety when vehicle automatically brakes;The preset first distance limit value is greater than the preset second distance limit value.

[0090] If not, the running speed of the target vehicle is adjusted.
