And S11, acquiring a vehicle distance display request, and acquiring lane information, the current speed and vehicle distance information from a vehicle sensor according to the vehicle distance display request, wherein the vehicle distance information comprises the distance between the vehicle body and the surrounding obstacles.

The user can set the function on the vehicle display screen, start the anti-collision function and the distance display function, the vehicle will obtain the vehicle state information including the location of the vehicle, the speed of the vehicle and the information of the obstacles around the vehicle, etc. from a plurality of sensors of the vehicle in real time at a fixed frequency according to the set distance display request.

The sensors used are mainly cameras, radars, lasers, ultrasonic waves, etc., which can detect light, heat, pressure or other variables for monitoring the state of the vehicle, and are usually located inside the front and rear bumpers, side-view mirrors, steering columns or on the windshield of the vehicle.

The vehicle-mounted radar is mainly located at the positions of a front bumper, a rear bumper, a left rear mirror and a right rear mirror of the vehicle, and obtains distance information of the front bumper, the rear bumper, obstacles in the front and the rear of the vehicle and distances between the left rear mirror and the right rear mirror and the obstacles on the left and the right sides of the vehicle through the vehicle-mounted radar. Obstacles include vehicles, roadblocks, pedestrians, railings, and the like.

The method comprises the steps of obtaining an image of a lane where a vehicle is currently running through a camera arranged on a windshield of the vehicle, and analyzing a lane line and the number of lanes where the vehicle is located from the image of the lane.

The vehicle speed at which the vehicle is currently running is measured by a vehicle speed sensor located at the wheel.

And S12, visually displaying the lane information and the vehicle distance information on a vehicle display screen.

And transmitting the vehicle, the lane information and the vehicle distance information to a vehicle-mounted central control according to the acquired lane information and the distance information between the vehicle and the surrounding obstacles, and displaying the data on a vehicle display screen in a visualized manner. The lane form, lane line, current lane position and distance between the vehicle and the surrounding obstacles are displayed. The display screen can mark the distance of the vehicle through lines so as to be simpler and easier to understand by users.

And S13, determining the warning distance between the vehicle body and the surrounding obstacles according to the lane information and the current vehicle speed, correspondingly marking the vehicle distance information on the vehicle display screen when the vehicle distance information reaches the warning distance in the corresponding direction, and sending out safety early warning.

When the distance between the vehicle and the surrounding obstacles is smaller than the warning distance in the corresponding direction, the vehicle is easy to have an accident.

For example, the warning distance of the front and rear cars may be set as: driving at high speed, namely when the speed is more than 100km/h, the warning distance is more than 100 meters; driving fast, namely when the speed is above 60km/h, the warning distance is numerically equal to the speed; the vehicle speed is 80km/h, and the warning distance is 80 meters. And when the vehicle is driven at a medium speed, namely the vehicle speed is about 50km/h, the warning distance is not less than 50 meters. When the vehicle is driven at a low speed, namely the vehicle speed is below 40km/h, the warning distance is not less than 30 meters. When the vehicle speed is below 20km/h, the warning distance is not less than 10 meters.

The left and right side warning distances of the vehicle can be determined according to whether the current driving lane is located on an outer lane or a central lane, and the optimal vehicle distance is further determined by carrying out multiple experimental measurements in combination with the vehicle speed. When the vehicle is located outside the lane, the warning distance will be greater than the warning distance located in the center lane.

When the vehicle speed is slow, the warning distances of the left side and the right side of the vehicle can be short, and the lateral distance is increased along with the acceleration of the vehicle speed. The warning distance is generally determined according to the vehicle speed and the difference of lanes. When the vehicle runs at a high speed, the warning distance can be 1.8 meters, when the vehicle runs at a high speed, the warning distance can be 1.6 meters, and when the vehicle runs at a low speed, the warning distance can be 1.2 meters. Further, if the vehicle is on the outer lane, the warning distance to the roadside, the railing, or the running vehicle is 1.4 meters, and if the vehicle is on the center lane, the warning distance to the vehicle may be 0.7 meters, and the warning distance between the vehicle and the sidewalk is 0.6 meters.

When the distance between the vehicle and the surrounding obstacles reaches the warning distance in the corresponding direction, the vehicle distance information in the corresponding direction is marked on the vehicle display screen, for example, the currently displayed vehicle distance is marked in red, the marked vehicle distance is displayed on the vehicle head-up display, safety early warning is sent out, a user is reminded to adjust the driving state of the vehicle, and the direction is decelerated or rotated so as to avoid accidents.

Example two

Referring to fig. 2, a vehicle distance warning method according to a second embodiment of the present invention includes steps S21-S26.

And S21, acquiring a vehicle distance display request, and acquiring lane information, the current speed and vehicle distance information from a vehicle sensor according to the vehicle distance display request, wherein the vehicle distance information comprises the distance between the vehicle body and the surrounding obstacles. The user can set the function on the vehicle display screen, start the anti-collision function and the distance display function, the vehicle will obtain the vehicle state information including the location of the vehicle, the speed of the vehicle and the information of the obstacles around the vehicle, etc. from a plurality of sensors of the vehicle in real time at a fixed frequency according to the set distance display request.

And S22, visually displaying the lane information and the vehicle distance information on a vehicle display screen.

And S23, respectively determining a first warning distance between a front bumper and a rear bumper of the vehicle body and a front obstacle and a second warning distance between the left rear-view mirror and the left obstacle and the right obstacle according to the lane information and the current vehicle speed.

According to the obtained lane position information and the current running speed of the vehicle, the warning distance between the vehicle and the surrounding obstacles is determined, the warning distance between the front bumper and the rear bumper of the vehicle body and the surrounding obstacles is determined as a first warning distance, the warning distance between the left rear-view mirror and the right rear-view mirror of the vehicle and the left and right side obstacles of the vehicle is a position warning distance, the warning distances between the vehicle and the front and rear obstacles can be set to be the same, and the warning distances between the vehicle and the left and right side obstacles can be set to be the same. When the distance between the vehicles is less than the warning distance, the vehicle is easy to have accidents.

For example, the first alert distance may be set to: driving at high speed, namely when the speed is more than 100km/h, the first warning distance is more than 100 meters; driving fast, namely when the speed is above 60km/h, the first warning distance is numerically equal to the speed; the vehicle speed is 80km/h, and the first warning distance is 80 meters. And (4) driving at a medium speed, namely when the speed is about 50km/h, the first warning distance is not less than 50 meters. When the vehicle is driven at a low speed, namely the vehicle speed is below 40km/h, the first warning distance is not lower than 30 meters. When the speed is below 20km/h, the safe distance is not less than 10 meters.

The second warning distance can be measured in a plurality of experiments according to the fact that the current driving lane is located on the outer side lane or the center lane, and the optimal vehicle distance is further determined by combining the vehicle speed. When the vehicle is located outside the lane, the warning distance will be greater than that located in the center lane. When the vehicle speed is slow, the warning distances of the left side and the right side of the vehicle can be short, and the lateral distance is increased along with the acceleration of the vehicle speed. The warning distance is generally determined according to the vehicle speed and the difference of lanes. The second warning distance may be 1.8 m when driving at a high speed, 1.6 m when driving at a high speed, and 1.2 m when driving at a low speed. If the second warning distance to the roadside, the balustrade, or the running vehicle is 1.4 meters in the outside lane, the second warning distance may be 0.7 meters when the vehicle is located in the center lane, and the second warning distance between the vehicle and the sidewalk is 0.6 meters.

In the actual driving process, the first warning distance and the second warning distance can be set by comprehensively considering the condition limit of the vehicle speed and the lane information.

Optionally, in some other optional embodiments, the maximum vehicle speed limited by the current driving lane may be determined according to the current driving lane, or the maximum vehicle speed may be obtained through a GPS, and the first warning distance and the second warning distance may be determined according to the maximum vehicle speed and the current driving lane. The method is the same as the method for determining the warning distance according to the vehicle speed and the driving lane.

And S24, correspondingly marking the vehicle distance information on the vehicle display screen when the vehicle distance information reaches the warning distance, and sending out safety early warning.

The first warning distance and the second warning distance can be limited according to the actual state and the actual running environment of the vehicle. When any distance information between the front bumper and the rear bumper of the vehicle body and the front obstacle and any distance information between the left rear view mirror and the right rear view mirror of the vehicle and the left obstacle and the right obstacle of the vehicle reach the second warning distance, the distance information in the corresponding direction is marked on the vehicle display screen, for example, the currently displayed distance is marked by red, the marked distance is displayed on the vehicle head-up display, safety early warning is sent out, a user is reminded to adjust the running state of the vehicle, and the speed is reduced or the rotating direction is changed, so that accidents are avoided. The early warning mode includes that setting up vibration sensor respectively in the direction all around of vehicle seat cushion, steerable sensor vibration in the direction that corresponds during the early warning. And the sound device for controlling the corresponding direction of the vehicle body can also give out sound warning during early warning.

And S25, fitting to form a lane curve according to the lane information, determining lane curvature, and judging whether the lane curvature is higher than a preset curvature threshold value.

If the lane curvature is higher than the preset curvature threshold, step S26 is executed.

And extracting lane lines according to the lane images, fitting to form a lane curve, and determining the curvature of a lane in front of the vehicle in driving from the lane curve, wherein optionally, the distance of 1-2m can be selected as a reference. And judging whether the curvature of the lane in front is higher than a preset curvature threshold value or not. The preset curvature threshold value marks that the vehicle is about to turn, when the curvature of a lane is too large, the vehicle is easy to have a rollover accident, and if the distance between the vehicle and surrounding obstacles is too small, the vehicle is easy to have an accident.

And S26, respectively adjusting the first warning distance and the second warning distance into a third warning distance and a fourth warning distance according to the lane curvature and the current vehicle speed.

And when the curvature of the lane is higher than the preset threshold value, correspondingly adjusting the first warning distance to a third warning distance according to the curvature of the current lane and the vehicle speed, and adjusting the second warning distance to a fourth warning distance. The greater the lane curvature, the greater the warning distance will be, the greater the vehicle speed, and the greater the warning distance will be. Wherein the third warning distance is greater than the first warning distance and the fourth warning distance is greater than the second warning distance. The specific warning distance adjustment can be carried out through a specific practical test to obtain the optimal warning distance, and the linear relation between the lane curvature, the vehicle speed and the third warning distance and the fourth warning distance is obtained through the practical situation.

Further, when the vehicle is located in the inner lane, the warning distance between the vehicle and the obstacle in the inner direction can be correspondingly increased. For example, at high speed, when the curvature of the lane is higher than a preset curvature threshold, the warning distance of the vehicle from the inside direction can be increased from 1.8 meters to 2 meters.

The display screen is updated at the same time when the adjusted warning distance is adjusted, when any vehicle distance information between the front bumper and the rear bumper of the vehicle body and the front and rear obstacles reaches a third warning distance, or any vehicle distance information between the left rear-view mirror and the right rear-view mirror of the vehicle and the left and right side obstacles of the vehicle reaches a fourth warning distance, the vehicle distance information in the corresponding direction is marked on the display screen and projected onto the head-up display of the vehicle, and the collision risk in the specific direction around the vehicle is reminded.

S27, judging whether the lane curvature is continuously lower than a preset curvature threshold value within a preset time;

if the lane curvature is continuously lower than the preset curvature threshold, returning to execute the step S23;

if the curvature of the lane is not continuously lower than the preset curvature threshold, step S28 is executed.

And S28, continuously determining a third warning distance and a fourth warning distance according to the lane curvature and the current vehicle speed.

When the vehicle continuously runs on the curve, the vehicle warning distance is determined according to the strategy of the step S26, and the collision warning is carried out on the vehicle by keeping the third warning distance and the fourth warning distance. After the vehicle has traveled away from the curve and reached the smooth section, the process may return to step S23, where the third warning distance is adjusted to the first warning distance, and the fourth warning distance is adjusted to the second distance.

Specifically, within a preset time period, whether the lane curvature is continuously lower than a preset curvature threshold value is judged, if yes, the mark vehicle is driven out of the curve area, and the vehicle continuously runs on a gentle straight road. When the vehicle runs on a road section with many curves on the mountain road, the strategy of step S26 can be continuously used for carrying out collision early warning, and when the vehicle leaves the road section, the strategy of step S23 is used for determining the warning distance and carrying out collision early warning.
