[0036] Next, the technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0037] As Figure 1 shown, in one embodiment, the ultrasonic sensor attachment detection method of the present invention includes steps S1 to S4.

[0038] Step S1, obtain the aftershock time and the first apparent distance of the ultrasonic sensor; the first apparent distance is the distance between the ultrasonic sensor and the detected object.

[0039] Specifically, the aftershock of the ultrasonic sensor refers to the time period from when the ultrasonic sensor is powered on until the ultrasonic starts to work stably. It is set that the ultrasonic sensor is in the self-transmitting and self-receiving working mode, and the number of single-wave transmissions is between 10 and 20. Therefore, in actual calculation, the first apparent distance is obtained by dividing the distance traveled by the first echo received after the ultrasonic sensor emits a wave by two. Usually, the distance traveled by the first echo is calculated by the start and end times of the vibration detected by the ultrasonic sensor.

[0040] Step S2: When the aftershock time is less than the first threshold within the first preset duration, it is determined that there is an attachment on the surface of the ultrasonic sensor.

[0041] As Figure 2 shown, when there is no attachment on the surface of the ultrasonic sensor, the aftershock time is usually between 780 us and 820 us. When there is an attachment on the surface of the ultrasonic sensor, the aftershock time is likely to be abnormal. Therefore, the attachment detection can be performed based on the abnormal aftershock time. Preferably, the first preset duration is 15 seconds.

[0042] As Figure 3 shown, in one embodiment, when the surface of the ultrasonic sensor is covered with ice, the aftershock time significantly decreases and is usually between 540 us and 570 us. Therefore, when within a continuous time period, that is, within the first preset duration, the aftershock time is less than the first threshold, it can be determined that there is an attachment on the surface of the ultrasonic sensor.

[0043] In one embodiment, the range of the first threshold is 400 us - 700 us. Preferably, the first threshold is 400 us, 550 us, or 700 us.

[0044] Step S3: When the moving speed of the ultrasonic sensor is greater than the preset speed and the aftershock time is greater than the second threshold within the second preset duration, it is determined that there is an attachment on the surface of the ultrasonic sensor.

[0045] As Figure 4 shown, in another embodiment, when the surface of the ultrasonic sensor is covered with ice and in a moving state, the aftershock time is divided into two levels. One level is between 1500 us and 2000 us, and the other level is around 2500 us. Therefore, when within a continuous time period, that is, within the second preset duration, the aftershock time is greater than the second threshold and the moving speed of the ultrasonic sensor is greater than the preset speed, it can be determined that there is an attachment on the surface of the ultrasonic sensor. Among them, the reason why the ultrasonic sensor needs to be in a moving state is to avoid false alarms of attachments caused by fixed obstacles at close range. Preferably, the second preset duration is 15 seconds. The preset speed is 3 km / h.

[0046] In one embodiment, the range of the second threshold is 1600 us - 2600 us. Preferably, the second threshold is 1600 us, 2100 us, or 2600 us.

[0047] Step S4. When, within a third preset time period, the cumulative time during which the moving speed of the ultrasonic sensor is greater than a preset speed and the first displayed distance is less than a third threshold reaches a fourth preset time period, it is determined that there is an attachment on the surface of the ultrasonic sensor.

[0048] When the surface of the ultrasonic sensor is covered with ice and there is a cavity in the ice, the ice fails to fit closely to the surface of the ultrasonic sensor, resulting in no abnormality in the aftershock time of the ultrasonic sensor. Since there is a gap between the attachment and the ultrasonic sensor, the first displayed distance received by the ultrasonic sensor can be small. Therefore, to avoid missed detection of attachments, the present invention uses the first displayed distance detection of ultrasonic waves to detect attachments.

[0049] As Figure 5 shown, in another embodiment, when the surface of the ultrasonic sensor is covered with ice and the ice has a cavity, the first displayed distance of the ultrasonic sensor is basically within 300 mm and is relatively stable. Therefore, when, within a continuous time period, that is, the third preset time period, the cumulative time during which the moving speed of the ultrasonic sensor is greater than a preset speed and the first displayed distance is less than a third threshold reaches a fourth preset time period, it can be determined that there is an attachment on the surface of the ultrasonic sensor. Among them, the reason why the ultrasonic sensor needs to be in a moving state is to avoid false alarms of attachments caused by fixed obstacles at close range. Preferably, the third preset time period is 15 seconds. The fourth preset time period is 10 seconds. The preset speed is 3 km / h.

[0050] In one embodiment, the range of the third threshold is 150 mm to 550 mm. Preferably, the third threshold is 150 mm, 350 mm or 550 mm.

[0051] In one embodiment, the method for detecting attachments on the ultrasonic sensor of the present invention further includes obtaining the offset of the aftershock frequency of the ultrasonic sensor; when, within a fifth preset time period, the difference between the offset of the aftershock frequency and a preset aftershock frequency offset is greater than a preset threshold, it is determined that there is an attachment on the surface of the ultrasonic sensor. Specifically, under normal circumstances, the aftershock frequency during the aftershock of the ultrasonic sensor generally stabilizes near a specific value. When the attachment is closely connected to the ultrasonic sensor, the aftershock frequency of the ultrasonic sensor will change greatly. Therefore, first calculate the offset of the aftershock frequency compared to the specific value, that is, the aftershock frequency offset, and then obtain the preset aftershock offset recorded at the factory of the ultrasonic sensor. When the deviation between the aftershock frequency offset of the ultrasonic sensor and the preset aftershock frequency offset exceeds a certain range, it can be considered that there is an attachment on the surface of the ultrasonic sensor. Preferably, the fifth preset time period is 15 seconds. Since both the aftershock frequency offset and the preset aftershock frequency offset are recorded as percentages, the preset threshold can be set to 6%.

[0052] The protection scope of the ultrasonic sensor attachment detection method described in the embodiments of the present invention is not limited to the execution order of the steps listed in this embodiment. Any solution achieved by adding or subtracting steps of the prior art and replacing steps according to the principle of the present invention is included in the protection scope of the present invention.

However, the implementation devices of the ultrasonic sensor attachment detection system described in the present invention include, but are not limited to, the structures of the ultrasonic sensor attachment detection system listed in this embodiment. Any structural deformation and replacement of the prior art made according to the principle of the present invention are included in the protection scope of the present invention.

[0054] As Figure 6 shown, in one embodiment, the ultrasonic sensor attachment detection system of the present invention includes an acquisition module 61, a first judgment module 62, a second judgment module 63, and a third judgment module 64.

[0055] The acquisition module 61 is used to acquire the aftershock time and the first apparent distance of the ultrasonic sensor.

[0056] The first judgment module 62 is connected to the acquisition module 61 and is used to judge that there is an attachment on the surface of the ultrasonic sensor when the aftershock time is less than the first threshold within the first preset duration.

[0057] The second judgment module 63 is connected to the acquisition module 61 and is used to judge that there is an attachment on the surface of the ultrasonic sensor when the moving speed of the ultrasonic sensor is greater than the preset speed and the aftershock time is greater than the second threshold within the second preset duration.

[0058] The third judgment module 64 is connected to the acquisition module 61 and is used to judge that there is an attachment on the surface of the ultrasonic sensor when, within the third preset duration, the time when the moving speed of the ultrasonic sensor is greater than the preset speed and the first apparent distance is less than the third threshold accumulates to the fourth preset duration.

[0059] Among them, the structures and principles of the acquisition module 61, the first judgment module 62, the second judgment module 63, and the third judgment module 64 correspond one by one to the steps in the above ultrasonic sensor attachment detection method, so they will not be elaborated here.
