Description

Technical Field

[0001] This application belongs to the technical field of electric vehicles, specifically relating to warning control methods, devices, and equipment for vehicles. Background Technology

[0002] Currently, the drive motors of electric vehicles are relatively quiet at low speeds. Therefore, electric vehicles must be equipped with low-speed warning devices to alert drivers of moving obstacles around the vehicle when traveling at low speeds.

[0003] In existing technology, when the low-speed alarm mode is activated, the low-speed alarm emits a fixed sound pressure level when the electric vehicle's speed falls below a threshold. In noisy environments, the sound pressure level is too low to effectively warn of moving obstacles around the vehicle. In quiet environments or when there are no pedestrians nearby, the alarm still sounds, resulting in higher power consumption for the vehicle. Therefore, in these situations, the low-speed alarm may not meet actual needs, leading to low warning efficiency. Summary of the Invention

[0074] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0075] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0076] It should be noted that although the terms "first," "second," etc., are used to describe various types of information in the embodiments of this application, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. Optionally, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0077] It should be understood that the terms "comprising" or "including" indicate the presence of the previously mentioned features, steps, or operations, but do not preclude the presence, occurrence, or addition of one or more other features, steps, or operations. The terms "and / or," etc., used in this application can be interpreted as inclusive, or mean any one or any combination thereof. Optionally, "A and / or B" means "any one of the following: A; B; A and B." Additionally, the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0078] Figure 1 This is a schematic diagram illustrating an application scenario provided by an embodiment of this application. Please refer to [link / reference]. Figure 1 , Figure 1 It includes an electric vehicle 100, which includes at least a headlight 101, a taillight 102, and a speaker 103.

[0079] The speaker 103 can be used as a low-speed alarm to amplify the alarm sound and warn of movable obstacles around the vehicle.

[0080] In related technologies, when the electric vehicle 100 travels at a speed below a threshold, the speaker 103 emits an alarm sound at a fixed sound pressure level. In noisy environments, the alarm sound emitted at a fixed sound pressure level is too weak to effectively warn of movable obstacles around the vehicle. Even in quiet environments or when there are no pedestrians nearby, the speaker 103 still emits an alarm sound at a fixed sound pressure level, resulting in higher power consumption for the vehicle.

[0081] In the above process, low-speed alarms may not meet the actual needs, resulting in low warning efficiency.

[0082] To resolve the above technical issues, please refer to [link / reference]. Figure 1 The electric vehicle 100 may also be equipped with a sound pressure sensor 104 and a radar 105.

[0083] The sound pressure sensor 104 can be used to measure the sound pressure level of noise and convert the noise into an electrical signal. The radar 105 can be used to detect objects around the vehicle; the radar 105 can be an ultrasonic radar, millimeter-wave radar, or lidar, and no limitation is made here.

[0084] This application provides a vehicle warning control method, which uses radar 105 to determine whether there are movable obstacles around the vehicle. If so, a sound pressure sensor 104 measures the ambient sound pressure of the vehicle's environment, and controls the speaker 103 to emit sound based on the ambient sound pressure, and / or controls the headlights 101 or taillights 102 to flash, thereby achieving adaptive control of vehicle warning. While achieving the warning effect, this method reduces the vehicle's power consumption and improves warning efficiency.

[0085] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; for the same or similar content, the description will not be repeated in different embodiments.

[0086] Figure 2This is a flowchart illustrating a vehicle warning control method provided in an embodiment of this application. The executing entity in this embodiment can be a warning control device for an electric vehicle, or a warning control unit installed in the electric vehicle. The warning control unit can be implemented through software or a combination of software and hardware. See also... Figure 2 The method includes:

[0087] S201, Obtain the speed of the target vehicle.

[0088] The target vehicle may be equipped with multiple speakers and multiple lights.

[0089] The target vehicle can be an electric vehicle. The vehicle speed can be the speed at which the target vehicle is traveling.

[0090] Optionally, the speed of the target vehicle can be obtained according to a preset period.

[0091] For example, the preset period can be 100 milliseconds, and there is no limit to this.

[0092] Optionally, the speed of the target vehicle can be obtained by: obtaining the warning mode of the target vehicle; when the warning mode is determined to be an adaptive warning mode, obtaining the speed of the target vehicle.

[0093] The warning mode is either an adaptive warning mode or a normal warning mode.

[0094] Optionally, the target vehicle is equipped with a display screen. Before acquiring the vehicle's speed, the vehicle's warning mode can be set in the following ways: displaying a settings page on the display screen; or setting the vehicle's warning mode to adaptive warning mode in response to the selection of the adaptive warning control.

[0095] The settings page includes both adaptive alert controls and normal alert controls.

[0096] Below, in conjunction with Figure 3 The process of setting the vehicle's warning mode is explained.

[0097] Figure 3 This is a schematic diagram of a display screen interface provided in an embodiment of this application. Please refer to [link / reference]. Figure 3 This includes interfaces 301 and 302.

[0098] Please refer to interface 301, which includes settings controls. Users can click the settings controls to display the alert mode settings page on the screen. The alert mode settings page includes: a normal alert control (set to on or off) and an adaptive alert control (set to on or off). Only one of the normal alert control and the adaptive alert control can be enabled at a time.

[0099] Please refer to interface 302. If the user needs to set the alert mode to adaptive alert mode, they can click on the selection control corresponding to adaptive alert mode to set the alert mode to adaptive alert mode.

[0100] S202. When the vehicle speed is greater than 0 and less than or equal to the preset vehicle speed, determine whether there are any movable obstacles around the target vehicle.

[0101] The area surrounding the target vehicle can be a circle with the target vehicle as the center and a preset length as the radius, or it can be a range less than the preset length from the vehicle body. Different preset lengths can also be set for the front, rear, left, and right sides of the vehicle body, creating ranges less than different preset lengths. There are no specific limitations. The preset length can be pre-set according to actual needs.

[0102] Movable obstacles can be obstacles that can move freely, such as pedestrians, pets, etc.

[0103] Specifically, the system determines whether the target vehicle's speed is greater than 0 and less than or equal to a preset speed. If the speed is greater than 0 and less than or equal to the preset speed, the detection device determines whether there are any movable obstacles around the target vehicle. If there are no movable obstacles, the vehicle can be driven normally.

[0104] The detection devices can be installed on the target vehicle. Multiple detection devices can be installed on the exterior of the target vehicle.

[0105] Optionally, the presence of movable obstacles around the target vehicle can be determined by the following feasible methods: obtaining the driving direction of the target vehicle; determining at least one target detection device and the detection area of ​​each target detection device among multiple detection devices based on the driving direction; and detecting whether there are movable obstacles around the target vehicle within the corresponding detection area using at least one target detection device.

[0106] The direction of travel can be either forward or backward.

[0107] If the direction of travel is forward, the target detection device can be multiple detection devices on the front of the vehicle; if the direction of travel is backward, the target detection device can be one detection device on the rear of the vehicle.

[0108] Different detection devices can have different detection areas. For example, when the vehicle is traveling in the forward direction, the detection areas of the detection devices on both sides of the front of the vehicle are smaller than the detection area of ​​the detection device directly in front of the vehicle.

[0109] S203. If there is a movable obstacle, the ambient sound pressure of the target vehicle's environment is obtained, the target power is determined based on the ambient sound pressure, the target speaker is identified among multiple speakers, and the target speaker is controlled to emit sound based on the target power; and / or, the target headlight is identified among multiple headlights, and the target headlight is controlled to flash.

[0110] Ambient sound pressure level (ASPR) can represent the magnitude of sounds in the surrounding environment. ASPR can be obtained from at least one sound pressure sensor. Headlight flashing can be performed in a preset manner; the specific flashing method is not limited here.

[0111] Specifically, the system determines that there are movable obstacles around the target vehicle, obtains the ambient sound pressure of the environment where the target vehicle is located, determines the target power based on the ambient sound pressure, obtains the target detection area where the movable obstacle is located, determines the target speaker among the plurality of speakers based on the target detection area, and controls the target speaker to emit sound based on the target power; and / or, determines the target headlight among the plurality of headlights based on the target detection area, and controls the target headlight to flash to warn of the movable obstacle.

[0112] The vehicle warning control method provided in this embodiment acquires the speed of the target vehicle. When the speed is greater than 0 and less than or equal to a preset speed, it determines whether there are any movable obstacles around the target vehicle. If there are movable obstacles, it acquires the ambient sound pressure of the target vehicle's environment, determines the target power based on the ambient sound pressure, identifies the target speaker among multiple speakers, and controls the target speaker to emit sound based on the target power; and / or, identifies the target headlight among multiple headlights and controls the target headlight to flash. This achieves adaptive control of vehicle warnings, reducing vehicle power consumption and improving warning efficiency while still providing a warning effect.

[0113] Below, in conjunction with Figure 4 The illustrated embodiment provides a further detailed description of the process (S202) for determining whether there are movable obstacles around the target vehicle.

[0114] Figure 4 This is a flowchart illustrating another vehicle warning control method provided in an embodiment of this application. Based on the above embodiments, see also... Figure 4 The method includes:

[0115] S401, Obtain the driving direction of the target vehicle.

[0116] The direction of travel can be forward or backward.

[0117] Optionally, the rotation direction of the drive motor of the target vehicle can be obtained, and the driving direction of the target vehicle can be determined based on the rotation direction.

[0118] If the rotation direction is clockwise, then the travel direction is the forward direction;

[0119] If the rotation direction is reversed, the driving direction is backward.

[0120] Optionally, the driving signal from the microcontroller unit (MCU) of the target vehicle can be acquired, and the driving direction of the target vehicle can be determined based on the driving signal.

[0121] If the driving signal is a forward signal, then the driving direction is the forward direction;

[0122] If the driving signal is a reversing signal, then the driving direction is the reverse direction.

[0123] S402. Based on the direction of travel, determine at least one target detection device and the detection area of ​​each target detection device among multiple detection devices.

[0124] The detection device can be either radar or a camera; there is no limitation on this.

[0125] Multiple detection devices can be divided according to their arrangement, including a front detection device, a left front detection device, a right front detection device, a rear front detection device, a left rear detection device, and a right rear detection device. Different detection devices correspond to different detection areas.

[0126] The detection area can be preset according to actual needs. For example, users can set it in the settings controls on the display screen, or they can set it according to the settings parameters sent from the cloud; there is no limitation here.

[0127] Specifically, the mapping relationship between the driving direction and the target detection device and the detection area is obtained. Based on the mapping relationship and the driving direction, at least one target detection device and the detection area of ​​each target detection device are determined among multiple detection devices.

[0128] For example, the mapping relationship can be shown in Table 1.

[0129] Table 1

[0130]

[0131] S403. Obtain the detection results of each target detection device in the corresponding detection area to obtain multiple detection results.

[0132] The detection results can be used to indicate whether there are movable obstacles in the corresponding detection area.

[0133] Specifically, each target detection device performs detection on its corresponding detection area, obtains the detection result of each target detection device within the corresponding detection area, and obtains multiple detection results.

[0134] Below, taking any one of the multiple detection devices as an example, the corresponding detection area can be detected in the following two ways:

[0135] Method 1: The target detection device acquires multiple detection images, each including a corresponding detection area, and performs obstacle recognition on the multiple detection images.

[0136] Method 2: The target detection device detects obstacles within the corresponding detection area at a preset cycle that are less than or equal to a preset length.

[0137] The preset length can be set in advance according to actual needs.

[0138] Optionally, the detection results of the target detection device in the corresponding detection area can be obtained by the following feasible methods: obtaining the obstacle scanning results of the target detection device in the corresponding detection area; when the obstacle scanning results indicate that there is an obstacle in the corresponding detection area, determining the obstacle type; and determining the detection result based on the obstacle scanning results and the obstacle type.

[0139] The obstacle scan results can be used to indicate whether there are obstacles in the corresponding detection area.

[0140] The obstacle type can be either movable or immovable. The obstacle type can be determined based on the detection results.

[0141] For example, if the detection results include identified pedestrians or pets, the obstacle type can be determined to be movable. If the detection results do not include pedestrians or pets, the obstacle type can be determined to be immovable.

[0142] For example, if the detection results include at least one obstacle with a distance less than or equal to a preset length, the distance trajectory between each obstacle and the target vehicle is determined, and the obstacle type is determined based on the distance trajectory. The distance trajectory includes the straight-line distance between the obstacle and the target vehicle detected in each preset cycle. If the distance trajectory does not conform to the preset type, the obstacle is determined to be a movable obstacle; if the distance trajectory conforms to the preset type, the obstacle is determined to be immovable.

[0143] If the obstacle scan result indicates that there is an obstacle in the corresponding detection area, and the obstacle type is movable, then it is determined that there is a movable obstacle in the corresponding detection area indicated by the detection result.

[0144] If the obstacle scan result indicates that there are no obstacles in the detection area, or the obstacle type is immovable, then it is determined that there are no movable obstacles in the detection area corresponding to the detection result.

[0145] S404. Determine whether there is at least one detection result among multiple detection results that indicates the existence of a movable obstacle within the corresponding detection area.

[0146] If not, proceed with S405.

[0147] If so, execute S406.

[0148] For example, suppose there are 5 detection results. If one of the 5 detection results indicates that there is a movable obstacle in the corresponding detection area, then S406 is executed.

[0149] S405. Determine that there are no movable obstacles around the target vehicle.

[0150] S406. It is determined that there are movable obstacles around the target vehicle.

[0151] The implementation details of each step in this application embodiment can be found in the description of the corresponding steps or operations in the above method embodiments; repeated content will not be repeated.

[0152] The vehicle warning control method provided in this embodiment obtains the driving direction of the target vehicle, determines at least one target detection device and the detection area of ​​each target detection device among multiple detection devices based on the driving direction, and obtains the detection result of each target detection device within its corresponding detection area, resulting in multiple detection results. If at least one of the multiple detection results indicates the presence of a movable obstacle within the corresponding detection area, then it is determined that a movable obstacle exists around the target vehicle. This enables the vehicle to detect surrounding movable obstacles, serving as a prerequisite for adaptive warning control, making the vehicle more intelligent and improving warning efficiency.

[0153] Below, in conjunction with Figure 5 The illustrated embodiment provides a further detailed description of the process (S203) for controlling the speaker of the target vehicle to emit sound and / or controlling the headlights of the target vehicle to flash.

[0154] Figure 5 This is a flowchart illustrating another vehicle warning control method provided in an embodiment of this application.

[0155] See also Figure 5 The method includes:

[0156] S501, Obtain the ambient sound pressure of the target vehicle's location.

[0157] It can acquire the ambient sound pressure transmitted by at least one sound pressure sensor.

[0158] Optionally, at least one detection result indicating the presence of a movable obstacle within the corresponding detection area can be obtained. Based on at least one detection result, at least one target detection area can be determined. Based on each target detection area, a target sound pressure sensor corresponding to the target detection area can be determined among multiple sound pressure sensors, and the ambient sound pressure of at least one target sound pressure sensor can be obtained.

[0159] S502. Determine the target power based on the ambient sound pressure.

[0160] The target power can be expressed as the speaker's sound output power. For example, the target power is 50 dB. The target power can be determined based on the ambient sound pressure level to achieve a warning effect and save energy when the ambient sound pressure level is low.

[0161] Optionally, the target power can be determined based on the maximum ambient sound pressure in at least one ambient sound pressure level.

[0162] Optionally, the target power can be determined in the following feasible ways: if the ambient sound pressure is less than or equal to the preset sound pressure, the target power is determined to be the preset power; if the ambient sound pressure is greater than the preset sound pressure, the target power is determined based on the ambient sound pressure and the preset adjustment value.

[0163] Optionally, when the ambient sound pressure is greater than the preset sound pressure, the target power can be determined in the following feasible way: the sum of the ambient sound pressure and the preset adjustment value is determined to obtain the target sound pressure; if the target sound pressure is greater than or equal to the limit sound pressure, the target power is determined to be the power corresponding to the limit sound pressure; if the target sound pressure is less than the limit sound pressure, the target power is determined to be the power corresponding to the target sound pressure.

[0164] For example, suppose the preset sound pressure level is 40 dB, the preset power is 50 dB, and the preset adjustment value is 10 dB.
