Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of a collision avoidance method for an automobile according to the present invention, the collision avoidance method for an automobile includes:
step S100, acquiring a radar signal in the driving process of the automobile through a radar installed on the automobile;
in this embodiment, a plurality of radars can be installed on the car, and the radar can be laser radar, can be microwave radar, also can be ultrasonic radar. In this embodiment, the radar is ultrasonic radar, and in the driving process of car, the radar can be to surrounding environment transmission ultrasonic signal, and if there is the target object to touch radar signal and will reflect the echo, the radar receiver can receive the echo signal, through handling echo signal to obtain the moving speed of distance, the direction of target object and target object of this target object and car.
Step S200, obtaining obstacle information of obstacles on a driving road surface according to the radar signal;
through processing and recognition of the radar echo signals, obstacles which are possibly collided with the vehicle in the automobile running environment are recognized, and obstacle information related to the obstacles is extracted. In this embodiment, the obstacle may be a wooden stake, a large stone block, or the like on the road surface; it can also be a moving animal, a pedestrian. The obstacle information includes the height of the obstacle from the ground, the orientation of the obstacle, the speed of the obstacle, and the like.
In a real worldIn one embodiment, the number of the radars is multiple, wherein a first radar is arranged on a cross beam of the automobile chassis, and the first radar emits outwards within a certain range with the height h from the ground1If the first radar can receive the reflected wave from a direction, the direction is higher than or equal to h away from the ground1Detecting the distance of the object from the first radar and recording as D1(ii) a The plurality of radars further comprise a second radar arranged on a front bumper of the automobile, and the second radar emits outwards within a certain range and has a height h from the ground2Detects the distance of the object from the second radar and records as D2(ii) a The plurality of radars further comprise a third radar arranged on a rear bumper of the automobile, and the third radar emits outwards within a certain range and has a height h away from the ground3The distance of the detected object from the third radar is recorded as D3Wherein h is1Is greater than h2Height of (h)2Is greater than h3If D is1、D2、D3The difference between any two of the three values is within a preset range, so that the object can be identified as an obstacle, and the position of the obstacle is further determined; then, the position change of the object is monitored by utilizing the electromagnetic wave echo signal, and the speed of the obstacle can be calculated by combining the time. If D is1、D2、D3If the difference between the two values exceeds the preset range, the road surface is possibly a rugged road surface such as an uphill slope or a downhill slope, and the road surface is not judged to have an obstacle.
In one embodiment, step S200 includes:
step S210, performing data processing, analysis and identification on the radar signal, and extracting the obstacle information;
step S220, the obstacle information includes the height from the highest point of the obstacle to the driving road surface, the position of the obstacle, and the distance between the obstacle and the automobile.
In the embodiment, whether the automobile collides when passing through the obstacle is judged according to the height of the obstacle from the ground and the height of the automobile chassis; for example, if the highest position of the automobile chassis is 13 cm from the ground and the height of the obstacle is 15 cm, it is determined that the automobile will collide with the obstacle. Judging whether the automobile collides with the barrier or not according to the position of the barrier and the driving direction of the automobile; for example, if an obstacle appears directly in front of the vehicle and the vehicle is traveling forward, it is determined that the vehicle will collide with the obstacle if the traveling direction of the vehicle is not changed. And judging how long the automobile passes through the obstacle according to the distance between the obstacle and the automobile and the running speed of the automobile. For example, if the obstacle is 5000 meters ahead of the vehicle and the vehicle is traveling straight ahead at a speed of 60km/h, the vehicle will pass the obstacle after 5 minutes if the vehicle keeps traveling at that speed.
And step S300, executing a corresponding anti-collision strategy according to the obstacle information.
After the information such as the height of the obstacle from the ground, the distance between the obstacle and the automobile, the direction of the obstacle and the like is acquired, the automobile can adopt different anti-collision strategies according to different conditions, the automobile is controlled to make different anti-collision responses under different conditions, the collision of an automobile chassis caused by negligence or misjudgment of a driver is avoided, and the driving safety is ensured.
For example, when the distance between the automobile and the obstacle is one kilometer, the automobile is controlled to give an alarm, the position of the nearby obstacle is broadcasted in a voice mode, and a driver is prompted to avoid collision with the obstacle by controlling operations such as automobile lane changing and the like; when the distance between the automobile and the barrier is one hundred meters, the automobile is controlled to automatically brake.
In one embodiment, step S300 includes:
judging whether the distance between the barrier and the automobile is smaller than or equal to a first safety distance;
if the distance between the obstacle and the automobile is smaller than or equal to a first safety distance, judging whether the height of the obstacle from the ground is smaller than a first safety height;
and if the height of the obstacle from the ground is greater than or equal to the first safety height, monitoring the change of the spacing distance between the obstacle and the automobile in real time, and executing a corresponding anti-collision strategy according to the change of the spacing distance.
The first safety distance is set manually by a driver, and different values can be set according to the driving speed of the automobile, the road surface condition and the like. When the automobile runs at a higher speed, a longer first safety distance needs to be set than when the automobile runs at a lower speed; when the road surface condition is poor, a longer first safety distance needs to be set than when the road condition is good. For example, when the driving speed of the automobile is 100 km/h, the driving road surface of the automobile is dry asphalt road, and the first safety distance may be set to 1000 m; when the running speed of the automobile is 20 kilometers per hour, the running road surface of the automobile is a wet yellow mud road, and the first safety distance can be set to be 500 meters; when the driving speed of the automobile is 10 km/h, the driving road surface of the automobile is an ice surface, and the first safety distance may be set to 800 m.
If the weather with low visibility such as heavy fog, rain, snow and the like is met, the first safety distance can be set longer than that in sunny days.
If the distance between the barrier and the automobile is larger than the first safety distance, the barrier does not need to be monitored; if the distance between the barrier and the automobile is smaller than or equal to the first safety distance, judging whether the height of the barrier from the ground is smaller than the first safety height;
the first safety height is an obstacle height for ensuring that the automobile can safely pass through the obstacle, and is set by a person skilled in the art according to the chassis structure of the automobile and the chassis height of the automobile. When the height of the barrier is smaller than the first safety height, the automobile can not collide when passing through the barrier; when the height of the obstacle is greater than or equal to the first safety height, the automobile collides with the obstacle when passing through the obstacle.
For example, the first safety height may be set as the height from the lowest point of the chassis of the vehicle to the ground, and if the height of the obstacle is smaller than the height from the lowest point of the chassis of the vehicle to the ground, when the vehicle drives over the obstacle, the obstacle will not collide with the chassis, and the vehicle can pass through safely; if the height of the obstacle is greater than or equal to the height of the lowest point of the vehicle chassis from the ground, the obstacle may collide with the vehicle chassis when the vehicle drives over the obstacle.
When the height of the obstacle is greater than or equal to the first safety height, the distance change between the obstacle and the automobile needs to be continuously monitored, and if the obstacle is monitored to be farther away from the automobile, the monitoring of the obstacle can be stopped until the distance between the obstacle and the automobile is greater than the first safety distance; if the distance between the obstacle and the automobile is monitored to be closer and closer, corresponding early warning measures need to be taken to prevent the automobile from colliding with the obstacle.
In one embodiment, the step of monitoring a change in a separation distance between the obstacle and the vehicle in real time, and executing a corresponding anti-collision policy according to the change in the separation distance includes:
and monitoring the change of the spacing distance between the barrier and the automobile in real time, and controlling the automobile to run in a first early warning mode when the distance between the barrier and the automobile is less than or equal to a second safety distance, wherein the first safety distance is greater than all the second safety distances.
The second safety distance is set manually by the driver, and different values can be set according to the difference of the automobile running speed, the road surface condition and the like. And when the distance between the barrier and the automobile is smaller than or equal to the first safety distance, if the barrier is monitored to be closer to the automobile until the distance between the barrier and the automobile is smaller than or equal to the second safety distance, in order to ensure driving safety, the driver is reminded that the barrier needing to be avoided is nearby, and the first early warning mode is operated. The first early warning mode can be an alarm or a voice broadcast of barrier information.
In another embodiment, the step of controlling the vehicle to operate in the first warning mode when the distance between the obstacle and the vehicle is less than or equal to the second safe distance further includes:
monitoring the distance change between the automobile and the obstacle in real time;
and when the distance between the obstacle and the automobile is greater than a second safety distance, exiting the first early warning mode.
In some embodiments, from the driving path of the vehicle, the vehicle does not go over the obstacle, but only passes by the obstacle, when the vehicle first approaches the obstacle and then leaves the obstacle, the distance between the vehicle and the obstacle may be less than the second safety distance in the process that the vehicle approaches the obstacle, and when the vehicle is controlled to operate in the first early warning mode. And then, the automobile gradually gets away from the barrier until the distance between the barrier and the automobile is greater than the second safety distance, the automobile can be judged to be out of risk, and then the automobile is controlled to exit the first early warning mode.
In one embodiment, the step of controlling the vehicle to operate in the first early warning mode includes:
and controlling a loudspeaker installed on the automobile to send out first prompt information, wherein the first prompt information comprises the position of the obstacle and the distance between the obstacle and the automobile.
When the radar signal detects that the distance between the automobile and the obstacle is smaller than the second safety distance, the information of the obstacle can be transmitted to the central control system of the automobile, the central control system processes the information and then transmits the processed information to the broadcasting system of the automobile, the broadcasting system of the automobile carries out voice reminding on a driver through a vehicle-mounted loudspeaker, and the position of the obstacle and the distance between the obstacle and the automobile are broadcasted through voice. For example, the voice broadcast message may be "there is an obstacle 500 m in front of the vehicle, please take the driver to drive carefully. "can also be" there is an obstacle at 700 meters behind the right of the automobile, please take care to back up the automobile. After receiving the voice prompt, the driver controls the automobile to perform deceleration operation, braking operation or lane changing operation, so as to avoid collision with the obstacle.
In one embodiment, the step of monitoring the change of the separation distance between the obstacle and the vehicle in real time, and when the distance between the obstacle and the vehicle is less than or equal to a second safety distance, controlling the vehicle to operate in a first early warning mode, further includes:
when the distance between the obstacle and the automobile is smaller than or equal to a third safety distance, judging whether the automobile starts a braking system;
and if the automobile does not start the brake system, controlling the automobile to run in a second early warning mode, wherein the third safety distance is smaller than the second safety distance.
The third safety distance is preset by a person skilled in the art, and different values can be set according to different driving speeds and road conditions of the automobile. The third safety distance is less than the second safety distance. In some embodiments, after the vehicle sends the first prompt message, the driver does not notice the first prompt message, and does not control the vehicle to perform corresponding deceleration operation, braking operation or lane changing operation, so that the distance between the vehicle and the obstacle is less than the third safe distance. At the distance, the automobile is very close to the obstacle, the lane change operation cannot be carried out so that the automobile can not avoid the obstacle, and only the automobile can be controlled to carry out the braking operation.
And detecting the state of the automobile, judging whether a driver manually starts an automobile braking system, and controlling the automobile to run in a second early warning mode if detecting that the driver does not start the braking system.
In one embodiment, the step of controlling the vehicle to operate in the second early warning mode includes:
and starting the automobile braking system to control the wheels of the automobile to automatically decelerate.
And when the radar signal detects that the distance between the automobile and the obstacle is smaller than a third safety distance and the driver does not start braking operation, the automobile is controlled to automatically brake through a central control system of the automobile.
