Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a vehicle 1 according to an embodiment of the present invention, including: automobile body 10, radar 30 and controller 20 all set up in automobile body 10, radar 30 are used for surveying the peripheral object of vehicle, and radar 30 can be laser radar, ultrasonic radar. The controller 20 is connected to the radar 30 and the vehicle body 10, respectively, and the controller 20 is configured to perform processing based on data detected by the radar 30, for example, to control the vehicle body to travel based on the data detected by the radar, to implement automatic driving, and the like.
Referring to fig. 2, the present invention provides a method for detecting an interfering object, which is applied to the radar, and the method includes:
step S101: acquiring the speed and the driving direction of the vehicle;
the vehicle can be a common vehicle, an automatic driving vehicle and the like, and the radar acquires the speed of the vehicle currently running and the passing direction of the vehicle on the current road.
Step S102: acquiring an included angle between the detection target detected by the radar and the driving direction;
the detection range of the radar is a spatial range in which the radar can find a target, and the detection range is mainly related to radar performance, reflection characteristics and other factors, and the detection target can be a driving vehicle on a current running road, a vehicle which is static relative to the ground, a fence and the like. As shown in fig. 3, the included angle is an included angle between the detected target and the radar detection center due to the deviation of the driving direction.
Step S103: calculating radial frequency in the radial direction relative to the detection target according to the speed and the included angle;
as shown in fig. 3, the radial direction of the detection target refers to the direction in which the detection target is perpendicular to the radar. According to the running speed of the current vehicle and the included angle, the formula for calculating the radial frequency is
Figure BDA0003473584100000051
Wherein f is a radial frequency, V is a speed of the vehicle, λ is a wavelength of a transmission signal transmitted by the radar, and θ is an included angle between a detection target measured by the radar and the driving direction.
As can be seen from the calculation formula of the radial frequency, the radial frequency is directly calculated by using the speed of the vehicle, and the speed of the vehicle is the speed of the vehicle corresponding to the ground, and similarly, the speed of the vehicle is the speed of the vehicle corresponding to the stationary object on the ground.
Step S104: acquiring a frequency offset generated by the radar when the detection target is detected;
when the radar is distant from the target, the frequency of the transmitted signal transmitted by the radar and the frequency of the reflected signal reflected by the target will not be the same, and thus the frequency offset is: the doppler difference, in other words, the frequency offset is the subtraction of the frequency of the transmitted signal and the frequency of the reflected signal of the radar. Specifically, referring to fig. 5, the step of acquiring a frequency offset generated by the radar when detecting the detection target further includes:
step S1041: acquiring a first frequency of a transmission signal transmitted by the radar;
step S1042: acquiring a second frequency of an echo signal reflected by the detection target received by the radar;
and S1043, calculating a difference value between the first frequency and the second frequency to obtain the frequency offset.
Calculating the difference between the first frequency and the second frequency specifically includes: f. of1-f2Δ, wherein f1Is said first frequency, f2Δ is the frequency offset for the second frequency.
Step S105: judging whether the difference value between the frequency deviation and the radial frequency is smaller than a first preset threshold value or not;
step S106: if so, determining that the detection target is an interference object;
the first preset threshold is a predefined value, and a specific value for the value can be set according to actual conditions. When the difference between the frequency offset and the radial frequency is smaller than a first preset threshold value, the frequency offset and the radial frequency are close, the radial frequency is calculated according to the speed of the vehicle (the speed of the vehicle is the speed of the vehicle corresponding to a stationary object on the ground), the radial frequency is a comparison object of the frequency offset generated by the radar when the detection object is detected, the comparison object is not a fixed value and is related to the speed and the included angle of the vehicle, and compared with a fixed value method, the error of the comparison method is lower and more accurate.
In the embodiment of the invention, the speed and the driving direction of the vehicle are obtained, the included angle between the detection target detected by the radar and the driving direction is obtained, then the radial frequency relative to the detection target in the radial direction is calculated according to the speed and the included angle, the frequency deviation generated when the radar detects the detection target is obtained, and finally whether the difference value between the frequency deviation and the radial frequency is smaller than a first preset threshold value is judged; and if so, determining that the detection target is an interference object. The radial frequency is calculated according to the speed of the vehicle (the speed of the vehicle is the speed of the vehicle equivalent to a stationary object on the ground), and the radial frequency is a comparison object of frequency deviation generated by the radar when the detection object is detected, so that the comparison object is not a constant value and is related to the speed and the included angle of the vehicle, and compared with a constant value mode, the error of the comparison mode is lower and more accurate.
Referring to fig. 4, fig. 4 is a flowchart illustrating another embodiment of a method for detecting an interfering object according to the present invention, which is different from the above embodiments in that the method further includes:
step S107: acquiring the distance between the radar and the detection target;
step S108: calculating the transverse distance between the detection target and the vehicle according to the distance and the included angle;
according to the distance between the detection target and the radar and the included angle, the transverse distance is the distance between the actual position of the detection target and the radar, and the calculation of the transverse distance specifically comprises the following steps: d-R sin (θ), where d is a lateral distance, R is a distance that a detection target is perpendicular to the radar, and θ is an included angle.
Step S109: and judging whether the transverse distance is greater than or equal to a second preset threshold value, if so, entering the step S106.
When the transverse distance is greater than or equal to a second preset threshold value, it is indicated that the detected target is a target in a static state relative to the ground, and may be determined as an interference target, where the second preset threshold value is an error value of the radar when the transverse distance is actually detected.
Step S110: and if the difference value between the frequency deviation and the radial frequency is greater than or equal to a first preset threshold value, or the transverse distance is smaller than a second preset threshold value, determining that the detection target is other vehicles.
The embodiment of the invention has the beneficial effects that: different from the situation in the prior art, in the embodiment of the present invention, the distance between the detected object and the radar is obtained, then the lateral distance between the detected object and the vehicle is calculated according to the distance and the included angle, and then it is determined whether the lateral distance is greater than or equal to a second preset threshold, if yes, step S106 is performed, so that the interference object that is stationary relative to the ground within the detection range can be effectively determined, and the error is small.
