[0021] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0023] See also Figure 2 , which shows a flowchart for implementing a vehicle sensor control method provided by an embodiment of the present invention. Applied to a vehicle, for example, the vehicle sensor control method can be executed by a vehicle controller, a sensor controller on the vehicle, or another vehicle controller capable of controlling sensors, without specific limitation. The vehicle sensor can be an onboard lidar, onboard camera, or other sensor.

[0024] The above methods include:

[0025] S101: Acquire sensing data of a target vehicle, and determine whether the target vehicle is on an uphill road section or a downhill road section based on the sensing data;

[0026] Since vehicles usually travel on level roads, the onboard laser radar and onboard camera usually face forward with a fixed pitch angle. Figure 1 When a vehicle approaches the bottom of a slope, the target sensor can only capture information directly ahead. Information about the horizontal section ahead of the downhill section is lost, resulting in a limited field of view and a blind spot. If an obstacle happens to be outside the field of view at this time, excessive speed could cause an accident. This situation does not occur on horizontal sections of road.

[0027] Therefore, in the embodiment of the present invention, it is first determined whether the target vehicle is on an uphill section or a downhill section.

[0028] Specifically, in a possible implementation, the perception data may include: map data, positioning data, network data, image data acquired by a vehicle-mounted camera, point cloud data acquired by a lidar, and at least one of vehicle-mounted level meter data.

[0029] For example, the sensing data is level data collected by a level meter installed on the target vehicle. When the level data shows that the angle between the vehicle and the horizontal plane is greater than a preset angle threshold, it can be determined that the target vehicle is on an uphill or downhill section.

[0030] For another example, it is possible to comprehensively determine whether the target vehicle is on an uphill or downhill section through map data, positioning data, and network data.

[0031] Furthermore, since map data is updated slowly, the map data, positioning data, image data, and point cloud data can be combined to comprehensively determine the target vehicle's body tilt angle, effectively improving the accuracy of detection.

[0032] S102: If the target vehicle is on an uphill or downhill section, determine whether the current field of view of the target sensor meets a preset condition;

[0033] When the target vehicle is detected on an uphill or downhill section, the target sensor may have a blind spot problem. Figure 1 When the target vehicle is on a downhill section, its field of view is limited compared to a horizontal section, and it can only reach point A at most. Road conditions outside the field of view are unknown. This field of view cannot meet the target vehicle's current driving requirements and cannot guarantee safe driving of the target vehicle. Therefore, the embodiment of the present invention determines whether the current field of view meets preset conditions on an uphill or downhill section to determine whether the target vehicle can safely drive under the current field of view.

[0034] S103: If the current field of view does not meet the preset conditions, adjust the pitch angle of the target sensor and adjust the pitch angle of the target sensor to the target angle; wherein the pitch angle of the target sensor before the adjustment is the initial angle;

[0035] The pitch angle is the angle between the X-axis of the target sensor's body coordinate system and the plane of the target vehicle. When the X-axis of the target sensor's body coordinate system points above the plane of the target vehicle, the pitch angle is positive; when the X-axis of the target sensor's body coordinate system points below the plane of the target vehicle, the pitch angle is negative.

[0036] When it is detected that the current field of view does not meet the preset conditions, that is, the field of view is too narrow, if the target sensor detects an obstacle when obtaining the next frame of field of view information, there may not be enough time to brake and avoid it, which may cause a traffic accident.

[0037] Therefore, when the field of view of the target vehicle does not meet the preset conditions, the embodiment of the present invention adjusts the pitch angle of the target sensor to expand the field of view, so that the target sensor can detect farther on uphill or downhill sections, thereby avoiding traffic accidents caused by blind spots in the field of view and effectively improving the safety of the target vehicle.

[0038] For example, when the target vehicle is on an uphill section, the target sensor is tilted upward relative to the horizontal section. Therefore, in order to obtain more ground information, it is hoped that the target sensor will "lower its head", that is, reduce the pitch angle of the target sensor.

[0039] When the target vehicle is on a downhill section, the target sensor is tilted downward relative to the horizontal section. Therefore, it is hoped that the sensor will "raise its head", that is, increase the pitch angle of the target sensor. Figure 3 .

[0040] In a possible implementation, the target sensor may be a vehicle-mounted laser radar or a vehicle-mounted camera.

[0041] It should be noted that an adjustment mechanism is installed below the target sensor, and the pitch angle of the target sensor can be adjusted by controlling the movement of the adjustment mechanism.

[0042] S104: Obtain first field of view information of the target sensor before adjustment and second field of view information of the target sensor after adjustment, perform data fusion based on the first field of view information and the second field of view information to obtain target field of view information; wherein, the target sensor is fixed on the target vehicle, the pitch angle is adjustable, and the field of view of the target sensor is toward the direction of the target vehicle.

[0043] Depend on Figure 1 and Figure 3 As can be seen, because the target sensor's field of view is fixed, increasing the pitch angle, for example when the target vehicle is traveling downhill, can result in loss of some of the lower field of view information. Therefore, the present invention fuses the pre- and post-adjustment field of view information to generate target field of view information. This has a wider field of view and includes more road condition information, further improving driving safety and preventing traffic accidents caused by blind spots.

[0044] It should be noted that when the target sensor is a vehicle-mounted camera, both the first and second field of view information are images. Image fusion technology can be used to fuse the two images to obtain the target image (target field of view information). When the target sensor is a vehicle-mounted lidar, the first and second field of view information are point cloud images. Image fusion technology can also be used to fuse the two point cloud images to obtain the target electric cloud image (target field of view information). Image fusion technology is existing technology and will not be further described here.

[0045] In a possible implementation, S102 may include:

[0046] S1021: Determine the drivable time of the target vehicle in the current field of view;

[0047] S1022: If the drivable time of the target vehicle is not greater than the first preset time, determining that the current field of view does not meet the preset condition;

[0048] S1023: If the drivable time of the target vehicle is greater than the first preset time, it is determined that the current field of view meets the preset condition.

[0049] It takes time for the driver to detect the danger and react accordingly, and it also takes time for the car to respond. Figure 1 When the target vehicle is on a downhill road, the mileage that the target vehicle can travel within the current field of view is L1+L2, and the road conditions outside the field of view are unknown. To ensure safe driving, sufficient reaction time must be reserved, and the target vehicle's drivable time (the time the target vehicle travels L1+L2 mileage) should be long enough.

[0050] Therefore, the embodiment of the present invention determines whether the current field of view meets the preset conditions based on the drivable time of the target vehicle in the current field of view.

[0051] If the target vehicle's drivable time is not greater than the first preset time, there may not be enough time to brake and avoid, which may cause a traffic accident, and the preset condition is not met; if the target vehicle's drivable time is greater than the first preset time, it means that the vehicle has enough time to brake and avoid, and the preset condition is met.

[0052] It should be noted that the first preset time is the time the target vehicle can safely brake to avoid the collision, which is related to human reaction time and vehicle conditions and can be different according to actual application needs. The first preset time will be different depending on the model of the target vehicle.

[0053] Exemplarily, the first preset time may be 15 seconds.

[0054] In another possible embodiment, referring to Figure 1The distance that the target vehicle can travel on the slope is fixed, and whether the preset conditions are met mainly depends on L2. Since the field of view and pitch angle of the target vehicle are fixed, the greater the slope, the smaller the distance, and the smaller the slope, the greater the distance.

[0055] Based on this, in another possible implementation, whether the field of view meets the preset conditions can also be determined based on the target vehicle's body tilt angle, pitch angle, and field of view information under the current field of view. The specific implementation method is not limited here.

[0056] In a possible implementation, S1021 may include:

[0057] 1. If the target vehicle is on an uphill section, the target vehicle's drivable time is determined to be a second preset time; wherein the second preset time is not greater than the first preset time;

[0058] 2. If the target vehicle is on a downhill section, obtain the field of view information of the target sensor in the current field of view, and determine the target vehicle's drivable distance in the current field of view based on the field of view information; determine the target vehicle's drivable time based on the target vehicle's current speed and the target vehicle's drivable distance in the current field of view.

[0059] When the target vehicle is on an uphill section, the field of view is upward, and the drivable time cannot be determined based on the field of view information under the current field of view. In the embodiment of the present invention, it is assumed that the drivable time of the target vehicle on the uphill section is not greater than the first preset time, and the pitch angle of the target sensor is directly adjusted.

[0060] When the vehicle is on a downhill road, the field of vision is downward, refer to Figure 1 , the distance that the vehicle can travel within the currently detectable field of view can be determined based on the field of view information under the current field of view combined with map data, positioning data, etc.

[0061] For example, the position of the target vehicle on the slope is determined based on the positioning data, and the distance L1 from the position of the target vehicle to the bottom of the slope is obtained in combination with the map data. Then, the distance L2 that the target vehicle can travel on the horizontal road section is obtained based on the map data and the field of view information under the current field of view. L1+L2 is the drivable distance of the target vehicle in the current field of view, and the drivable time of the target vehicle can be roughly calculated by dividing it by the driving speed of the target vehicle.

[0062] For example, when the target sensor is a vehicle-mounted laser radar, the field of view information in the current field of view is the point cloud image captured by the vehicle-mounted laser radar at the current pitch angle. When the target sensor is a vehicle-mounted camera, the field of view information in the current field of view is the image captured by the vehicle-mounted camera at the current pitch angle.

[0063] In a possible implementation, the first preset time may be 15 seconds.

[0064] It should be noted that the first preset time is the time the target vehicle can safely brake to avoid the collision, which is related to human reaction time and vehicle conditions and can be different according to actual application needs. The first preset time will be different depending on the model of the target vehicle.

[0065] In a possible implementation, S103 may include:

[0066] S1031: If the target vehicle is on an uphill road, obtain the target vehicle's body tilt angle, determine a target angle based on the body tilt angle, and reduce the pitch angle of the target sensor downward to the target angle;

[0067] When the target vehicle is on an uphill road, the target angle can be determined directly based on the vehicle's tilt angle. For example, if the vehicle's tilt angle is small, the pitch angle adjustment is small; if the vehicle's tilt angle is large, the pitch angle adjustment is large to obtain more road surface information.

[0068] For example, the pitch angle change Δθ = k × α, where k is a coefficient and α is the vehicle body tilt angle. The value of k can be set according to actual application requirements.

[0069] Furthermore, since the field of view is special on an uphill section, the field of view will be blocked by the inflection point after reducing the pitch angle. Therefore, to simplify the calculation, when the target vehicle is on an uphill section, the target angle can be directly set to a preset angle.

[0070] S1032: If the target vehicle is on a downhill section, gradually increase the pitch angle of the target sensor upward according to a preset increment until the current field of view meets the preset conditions, and use the current pitch angle as the target angle.

[0071] When the target vehicle is on a downhill road, the target sensor has a fixed field of view. A large pitch angle can prevent detection of small obstacles close to the road. Therefore, the pitch angle should not be too large. In this embodiment, the target sensor's pitch angle is gradually increased to meet the requirements, avoiding excessive pitch angles that could affect the sensor's perception accuracy.

[0072] In a possible implementation, S104 may include:

[0073] S1041: If the target vehicle is on an uphill road, obtain first field of view information and second field of view information, and fuse the first field of view information and the second field of view information to obtain target field of view information;

[0074] S1042: If the target vehicle is on a downhill section, obtaining the first field of view information and the field of view information of the target sensor after each incremental adjustment, and fusing the first field of view information and the field of view information after each incremental adjustment to obtain the target field of view information;

[0075] The field of view information after the last incremental adjustment is the second field of view information.

[0076] When driving on an uphill road, the pitch angle is directly adjusted to the target angle, so the first field of view information and the second field of view information can be directly fused to obtain the target field of view information.

[0077] On downhill sections, in order to avoid excessive pitch angle affecting the perception accuracy of the target sensor, the pitch angle is adjusted gradually. For example, Figure 4 The pitch angle is adjusted to the target angle after two incremental adjustments. Based on this, in the embodiment of the present invention, the first field of view information before adjustment and the field of view information after two adjustments (including the second field of view information) can be fused to obtain more comprehensive field of view information.

[0078] In a possible implementation, after S104, the method may further include:

[0079] S105: At every preset time interval, the pitch angle of the target sensor is adjusted to the initial angle, and steps S101 to S104 are executed.

[0080] To obtain more road condition information, the target sensor can be switched back to its initial angle at preset intervals, thereby obtaining more road information and improving driving safety. Furthermore, as the target vehicle moves, the field of view changes rapidly. Therefore, the target angle and target field of view information are updated after each switch, improving the real-time accuracy of the target angle.

[0081] Exemplarily, the preset duration may be 1 second.

[0082] Among them, the preset time length can be adjusted according to road conditions and vehicle speed. When the vehicle speed is faster, the preset time length can be reduced to ensure the real-time and accuracy of the target field of view information.

[0083] Specifically, it can be set according to actual application requirements and is not limited here.

[0084] In a possible implementation, after S103, the method may further include:

[0085] S106: Control the target vehicle to decelerate.

[0086] Increasing or decreasing the pitch angle will cause some field of view information to be lost. At the same time, blind spots usually occur near turning points on uphill or downhill sections. If the target vehicle is traveling too fast at the turning point, it is easy to cause an accident. Therefore, after adjusting the pitch angle, the speed of the target vehicle can be appropriately reduced, thereby improving driving safety and avoiding traffic accidents.

[0087] In a possible implementation, the above method may further include:

[0088] S107: If the current field of view meets the preset conditions, or the target vehicle is on a horizontal road section, the pitch angle of the target sensor is adjusted to the initial angle.

[0089] When the target vehicle is on a level road or the field of view meets the preset conditions, there will be no blind spot problem. The pitch angle of the target sensor can be adjusted back to the initial angle to obtain the best field of view and detection accuracy.

[0090] It should be noted that the initial angle can be set according to actual application requirements, which can not only meet the field of view requirements but also obtain higher perception accuracy.

[0091] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
