Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A control method of a vehicle safety light, a control apparatus of a vehicle safety light, a non-transitory computer-readable storage medium, and a vehicle according to embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings and embodiments.
Referring to fig. 1, the present disclosure provides a vehicle control method, where the vehicle includes a safety warning light, and the vehicle control method includes:
s1: acquiring the distance of obstacles around the vehicle;
s2: and controlling the safety warning lamp to be automatically turned on and off according to the distance of the obstacle.
Specifically, the safety warning lamp is mainly used for warning collision risks of other vehicles or pedestrians, can adopt the existing safety lamps of the vehicles such as double-flashing lamps and brake lamps, and can also be specially provided with a lamp for warning collision risks. The distance of the obstacle around the vehicle can be acquired by ultrasonic ranging or laser ranging.
This embodiment of the disclosure's distance through detecting the peripheral barrier of vehicle to according to the automatic switching of the distance control safety warning light that detects, can effectively warn other vehicles or passerby control vehicle distance, suggestion safety risk has realized the intelligent control to opening safety warning light automatically, is of value to driver safety driving.
Referring to fig. 2, in some embodiments, the controlling the safety warning light to automatically turn on or off according to the distance includes:
s21: judging whether the distance of the obstacle is smaller than or equal to a preset distance threshold value or not;
s22: if yes, the safety warning lamp is controlled to be automatically started and in a flashing state.
For example, when other vehicles catch up right behind the vehicle and are less than the safety distance, the safety warning lamp is automatically controlled to be turned on; or when the vehicle turns around and turns around, the vehicle warns when other vehicles are less than the safe distance. Meanwhile, the distance threshold may be set according to the vehicle conditions, for example, the distance threshold may be set to 100m in case of high-speed driving, and the distance threshold may be set to 5m in case of the road conditions of racing vehicles. The driver can also set the distance threshold value according to the actual road condition. The safety warning lamp is in a flashing state when being turned on, and is beneficial to warning surrounding vehicles or pedestrians.
In some embodiments, the vehicle control method further includes: when the distance is reduced, the flashing frequency of the safety warning lamp is improved; when the distance is increased, the flashing frequency of the safety warning lamp is reduced or the safety warning lamp is turned off.
The blinking frequency is adjusted within a range that can be recognized by the naked eye, and a higher blinking frequency means a higher urgency of collision risk indication. Specifically, at the time of high-speed traveling, it is possible to blink at a frequency of 1Hz in a preset distance threshold range, for example, at a distance range of 75m to 100m, at a distance range of 50m to 75m, at a frequency of 5Hz, at a distance range of 25m to 50m, at a frequency of 10Hz, at a distance range of 25m to 10m, at a frequency of 15Hz, and at a frequency of 20Hz in a distance range of 10 m. Meanwhile, when the distance between the safety warning lamp and the vehicle body is increased and exceeds the threshold range, the safety warning lamp plays a warning role, the collision trend disappears at the moment, the safety warning lamp can be controlled to be turned off, and the threshold range of the safety warning lamp which needs to be turned off can be different from the threshold range of the safety warning lamp which is turned on. It is understood that other road conditions, such as racing road conditions, may be more finely divided within a distance threshold of 5m, for example, the flashing frequency of the warning light is adjusted within a distance segment of each meter. The driver can also divide the distance section by himself according to the actual road conditions.
Therefore, the flashing frequency of the warning lamp can be adjusted according to the distance so as to prompt the dangerous emergency degree of other vehicles or pedestrians.
In some embodiments, the vehicle control method further comprises adjusting the color of the safety warning light according to the flashing frequency.
Specifically, adjusting the color of the safety warning light includes adjusting the shade of the color while the color may be changed. For example, the flashing frequency of the warning lamp is f1, f2, f3, f4, f5 and f6 which are arranged from small to large, and when the flashing frequency is f1, the warning lamp is light yellow; when the flash frequency is f2, the warning lamp is dark yellow; when the flash frequency is f3, the warning lamp is light blue; when the flash frequency is f4, the warning lamp is dark yellow; when the flash frequency is f5, the warning light is light red; at a strobe frequency of f6, the warning light is deep red.
Thus, by adjusting the color of the safety warning lamp according to the flashing frequency, the safety risk can be more prominently prompted, and the emergency degree can be more prominently prompted.
In some embodiments, the vehicle control method further includes: detecting the visibility of the surrounding environment of the vehicle; and adjusting the distance threshold value according to the visibility.
When visibility of the surroundings of the vehicle is reduced, collisions are more likely to occur, and therefore the magnitude of the distance threshold is increased to perform safety risk identification in advance. Specifically, the conditions of rain fog and smoke dust in the environment can be measured through a visibility sensor, and basic parameters measured by the visibility sensor are particle size and speed, so that the visibility grade of the environment outside the vehicle, such as particle size distribution, visibility and the like, can be deduced. The visibility sensor may be mounted on the roof of the vehicle body as well as in the rear view mirror. For example, when the visibility is 200m in a rainy and foggy weather environment, the distance threshold is adjusted from 100m to 200 m.
Therefore, by detecting the visibility of the surrounding environment of the vehicle and automatically adjusting the distance threshold value, the safety risk can be identified in advance under the condition of low visibility such as rain and fog weather.
In some embodiments, the safety light further comprises a fog light, and the vehicle control method further comprises: and when the visibility is judged to be less than or equal to a preset visibility threshold value, if so, the fog lamp is controlled to be automatically started.
Specifically, the light penetrating power of the warning lamp is limited compared with that of a fog lamp, and in rainy and foggy weather and under the condition of low visibility, if a driver does not manually and timely turn on the fog lamp, due to the low visibility, other vehicles or pedestrians are difficult to see the warning lamp, and the warning lamp cannot effectively play a role in warning when being turned on. Specifically, the visibility threshold may be set to 200m, and the fog light is controlled to be automatically turned on in rainy and foggy days when the visibility is less than 200 m.
In some embodiments, the distance of the obstacle is obtained by means of ultrasonic ranging or laser ranging.
The ultrasonic wave generating device can be realized by a single chip microcomputer, the transmitting head of the ultrasonic sensor is driven to transmit ultrasonic signals after wave amplification, and the transmitted ultrasonic signals are reflected after encountering obstacles in the corresponding direction and are captured and transmitted by the receiving head of the ultrasonic sensor. When the transmitting head of the ultrasonic sensor transmits an ultrasonic signal, the calculating unit records the transmitting time, when the receiving head of the ultrasonic sensor receives a reflected signal, the calculating unit records the receiving time again, and the distance between the automobile and the obstacle in the preset direction is calculated according to the propagation speed of the ultrasonic wave in the air and the difference time between the receiving time and the transmitting time. Assuming that the time difference between the reception time and the transmission time is t1, and the propagation speed of the ultrasonic wave in the air is v, the distance d between the automobile and the obstacle is (t1 v)/2. The laser ranging measurement is received by the range finder after the emitted laser is reflected by the barrier, and the range finder records the round-trip time of the laser at the same time. Half the product of the speed of light and the round trip time is the distance between the rangefinder and the obstacle.
Therefore, the distance of the obstacle can be acquired by means of ultrasonic ranging or laser ranging.
In some embodiments, the vehicle control method further includes: identifying a position of an obstacle; and prompting to adjust the driving state of the vehicle according to the distance and the direction of the obstacle.
Specifically, the prompt for adjusting the driving state of the vehicle includes adjusting the driving speed and the driving direction. For example, when other vehicles are braked right ahead of the vehicle, the other vehicles right ahead are within the threshold distance range and the distance is reduced, and at the moment, the vehicle is prompted to run in a decelerated mode; and when other vehicles are within the threshold distance range in the left side direction of the vehicle and the distance is reduced, prompting the vehicle to adjust to the right side. It should be noted that the specific orientation of the obstacle can be identified by identifying the reflection direction of the received ultrasonic wave or identifying the direction of the reflected laser light.
Therefore, the driving state of the vehicle is prompted and adjusted according to the distance and the direction of the obstacle, so that the driver can recognize the direction of the obstacle, the driving state is adjusted according to the prompt, and the collision can be effectively avoided.
Referring to fig. 3, the present disclosure further provides a vehicle control apparatus 100 including: the acquisition module 10, the acquisition module 10 is used for acquiring the distance of the obstacles around the vehicle; and the control module 20 is used for controlling the safety warning lamp to be automatically turned on and off according to the distance.
Specifically, the safety warning lamp is mainly used for warning collision risks of other vehicles or pedestrians, can adopt the existing safety lamps of the vehicles such as double-flashing lamps and brake lamps, and can also be specially provided with a lamp for warning collision risks. The acquisition module 10 may obtain the distance of the obstacle around the vehicle by means of ultrasonic ranging or laser ranging.
The vehicle control device 100 of the embodiment of the present disclosure can effectively warn other vehicles or pedestrians to control the vehicle distance by detecting the distance between obstacles around the vehicle and controlling the safety warning light to be automatically turned on and off according to the detected distance, so as to prompt safety risks, realize the intelligent control of automatically turning on the safety warning light, and be beneficial to the safe driving of the driver.
In some embodiments, the control module 20 is further configured to determine whether the distance to the obstacle is less than or equal to a preset distance threshold, and control the safety warning light to automatically turn on and be in a flashing state when the distance is less than or equal to the preset distance threshold.
For example, when other vehicles catch up right behind the vehicle and are less than the safety distance, the safety warning lamp is automatically controlled to be turned on; or when the vehicle turns around and turns around, the vehicle warns when other vehicles are less than the safe distance. Meanwhile, the distance threshold may be set according to the vehicle conditions, for example, the distance threshold may be set to 100m in case of high-speed driving, and the distance threshold may be set to 5m in case of the road conditions of racing vehicles. The driver can also set the distance threshold value according to the actual road condition. The safety warning lamp is in a flashing state when being turned on, and is beneficial to warning surrounding vehicles or pedestrians.
In some embodiments, the control module 20 is further configured to increase the flashing frequency of the safety warning light when the distance is reduced; when the distance is increased, the flashing frequency of the safety warning lamp is reduced or the safety warning lamp is turned off.
The blinking frequency is adjusted within a range that can be recognized by the naked eye, and a higher blinking frequency means a higher urgency of collision risk indication. Specifically, at the time of high-speed traveling, it is possible to blink at a frequency of 1Hz in a preset distance threshold range, for example, at a distance range of 75m to 100m, at a distance range of 50m to 75m, at a frequency of 5Hz, at a distance range of 25m to 50m, at a frequency of 10Hz, at a distance range of 25m to 10m, at a frequency of 15Hz, and at a frequency of 20Hz in a distance range of 10 m. Meanwhile, when the distance of the safety warning lamp is increased and exceeds the threshold range, the safety warning lamp plays a warning role, the collision trend disappears at the moment, and the safety warning lamp can be controlled to be turned off. It is understood that other road conditions, such as racing road conditions, may be more finely divided within a distance threshold of 5m, for example, the flashing frequency of the warning light is adjusted within a distance segment of each meter. The driver can also divide the distance section by himself according to the actual road conditions.
Therefore, the flashing frequency of the warning lamp can be adjusted according to the distance so as to prompt the dangerous emergency degree of other vehicles or pedestrians.
In some embodiments, the control module 20 is further configured to adjust the color of the safety warning light according to the flashing frequency.
Specifically, adjusting the color of the safety warning light includes adjusting the shade of the color while the color may be changed. For example, the flashing frequency of the warning lamp is f1, f2, f3, f4, f5 and f6 which are arranged from small to large, and when the flashing frequency is f1, the warning lamp is light yellow; when the flash frequency is f2, the warning lamp is dark yellow; when the flash frequency is f3, the warning lamp is light blue; when the flash frequency is f4, the warning lamp is dark yellow; when the flash frequency is f5, the warning light is light red; at a strobe frequency of f6, the warning light is deep red.
Thus, by adjusting the color of the safety warning lamp according to the flashing frequency, the safety risk can be more prominently prompted, and the emergency degree can be more prominently prompted.
In some embodiments, the vehicle control apparatus 100 further includes a detection module for detecting visibility of an environment surrounding the vehicle; the control module 20 is further configured to adjust the distance threshold according to the visibility.
When visibility of the surroundings of the vehicle is reduced, collisions are more likely to occur, and therefore the magnitude of the distance threshold is increased to perform safety risk identification in advance. Specifically, the conditions of rain fog and smoke dust in the environment can be measured through a visibility sensor, and basic parameters measured by the visibility sensor are particle size and speed, so that the visibility grade of the environment outside the vehicle, such as particle size distribution, visibility and the like, can be deduced. The visibility sensor may be mounted on the roof of the vehicle body as well as in the rear view mirror. For example, when the visibility is 200m in a rainy and foggy weather environment, the distance threshold is adjusted from 100m to 200 m.
Therefore, the visibility of the surrounding environment of the vehicle is detected through the detection module, and the distance threshold is automatically adjusted through the control module 20, so that the safety risk can be identified in advance under the condition of low visibility in rain and fog weather and the like.
In some embodiments, the safety light further includes a fog light, and the control module 20 is further configured to, when determining whether the visibility is less than or equal to a preset visibility threshold, control the fog light to automatically turn on if the visibility is less than or equal to the preset visibility threshold.
Specifically, the light penetrating power of the warning lamp is limited compared with that of a fog lamp, and in rainy and foggy weather and under the condition of low visibility, if a driver does not manually and timely turn on the fog lamp, due to the low visibility, other vehicles or pedestrians are difficult to see the warning lamp, and the warning lamp cannot effectively play a role in warning when being turned on. Specifically, the visibility threshold may be set to 200m, and the fog light is controlled to be automatically turned on in rainy and foggy days when the visibility is less than 200 m.
In some embodiments, the obtaining module 10 obtains the distance of the obstacle by means of ultrasonic ranging or laser ranging.
The ultrasonic wave generating device can be realized by a single chip microcomputer, the transmitting head of the ultrasonic sensor is driven to transmit ultrasonic signals after wave amplification, and the transmitted ultrasonic signals are reflected after encountering obstacles in the corresponding direction and are captured and transmitted by the receiving head of the ultrasonic sensor. When the transmitting head of the ultrasonic sensor transmits an ultrasonic signal, the calculating unit records the transmitting time, when the receiving head of the ultrasonic sensor receives a reflected signal, the calculating unit records the receiving time again, and the distance between the automobile and the obstacle in the preset direction is calculated according to the propagation speed of the ultrasonic wave in the air and the difference time between the receiving time and the transmitting time. Assuming that the time difference between the reception time and the transmission time is t1, and the propagation speed of the ultrasonic wave in the air is v, the distance d between the automobile and the obstacle is (t1 v)/2. The laser ranging measurement is received by the range finder after the emitted laser is reflected by the barrier, and the range finder records the round-trip time of the laser at the same time. Half the product of the speed of light and the round trip time is the distance between the rangefinder and the obstacle.
In this way, the obtaining module 10 may obtain the distance of the obstacle through an ultrasonic ranging or a laser ranging.
In some embodiments, the vehicle control apparatus 100 further includes an identification module for identifying the orientation of the obstacle; the control module 20 is further configured to prompt adjustment of the driving state of the vehicle according to the distance and the direction of the obstacle.
Specifically, the prompt for adjusting the driving state of the vehicle includes adjusting the driving speed and the driving direction. For example, when other vehicles are braked right ahead of the vehicle, the other vehicles right ahead are within the threshold distance range and the distance is reduced, and at the moment, the vehicle is prompted to run in a decelerated mode; and when other vehicles are within the threshold distance range in the left side direction of the vehicle and the distance is reduced, prompting the vehicle to adjust to the right side. It should be noted that the specific orientation of the obstacle can be identified by identifying the reflection direction of the received ultrasonic wave or identifying the direction of the reflected laser light.
Therefore, the driving state of the vehicle is prompted and adjusted according to the distance and the direction of the obstacle, so that the driver can recognize the direction of the obstacle, the driving state is adjusted according to the prompt, and the collision can be effectively avoided.
