It should be considered that they are only exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application.

[0052] Obviously, the described embodiments are some embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0055] With the progress of society and the development of automotive technology, especially the application and popularization of autonomous driving technology, the driving collision safety and alarm facilities of low-speed driverless logistics vehicles are important parameters that users highly concern. How to accurately calculate and calibrate the vehicle's low-speed collision safety device and provide practical test schemes and equipment is crucial for vehicle design and development, and is also an important content for improving the vehicle's driving safety performance.

[0056] Regarding low-speed driverless logistics vehicles, how to configure and develop the vehicle's collision alarm device is a new field in the current industry. Especially, how to test and calibrate such devices is still blank in the industry. The development and calibration schemes of collision alarm devices in related technologies are all methods based on manual experience, which can neither ensure the effectiveness of the collision alarm device nor have a unified quantifiable evaluation standard. This leads to uncertainties in the actual utility of the collision alarm device of driverless logistics vehicles and poses great potential hazards to the safe driving of the corresponding vehicles.

[0057] The current method based on manual experience is arbitrary, unable to form mature and quantifiable technical indicators, and unable to ensure the effective triggering of the collision alarm device of driverless logistics vehicles when a collision occurs.

[0058] Therefore, there is an urgent need for a test method for vehicle collision alarms to ensure the effectiveness of the vehicle collision alarm device, thereby ensuring the safety and reliability of vehicle driving.

[0059] Please refer to Figure 1 , which shows a schematic flowchart of a test method for vehicle collision alarms provided by an embodiment of the present application. This test method for vehicle collision alarms can be applied to a test system for vehicle collision alarms. The test system for vehicle collision alarms includes a collision simulation unit, a collision alarm device, and a vehicle control unit, and specifically may include:

[0060] Step 101, the vehicle control unit obtains the deformation data of the collision alarm device and the vehicle state data; the deformation data is determined based on the speed of the vehicle, the speed and weight of the collision simulation unit.

[0061] Step 102, the vehicle control unit determines whether the vehicle state data meets the first safety collision condition.

[0062] Step 103: In response to the vehicle state data satisfying the first safety collision condition, the vehicle control unit calibrates the deformation data as the alarm parameter of the collision alarm device.

[0063] Step 104: In response to the vehicle state data not satisfying the first safety collision condition, based on the vehicle state data, the vehicle control unit uses a preset adjustment strategy to adjust the deformation data, and calibrates the result of the adjustment process as the alarm parameter of the collision alarm device.

[0064] It should be noted that the vehicle state data may include the vehicle appearance condition in the assembly area of the collision alarm device. The first safety collision condition may be that the vehicle appearance condition in the collision alarm device area is not damaged.

[0065] It should be noted that the deformation data may include at least one of the air pressure change rate corresponding to the collision alarm device and the voltage change rate corresponding to the collision alarm device.

[0066] In this way, through the collision simulation unit, a collision test can be performed on the collision alarm device to obtain the deformation data of the collision alarm device and the vehicle state data. Then, based on the relationship between the vehicle state data and the first safety collision condition, the alarm parameter of the collision alarm device can be more effectively calibrated, ensuring the accuracy of the alarm parameter of the collision alarm device, and thus ensuring the reliability of the collision alarm of the low-speed unmanned vehicle.

[0067] Optionally, in a possible implementation manner of this embodiment, the vehicle collision alarm test system further includes a test control unit and an actuator. Before step 101, first, the test control unit sends the speed and weight of the collision simulation unit to the actuator. Second, based on the speed and weight of the collision simulation unit, the actuator controls the collision simulation unit to perform a collision test process on the collision alarm device of the vehicle. Third, the collision alarm device generates the deformation data of the collision alarm device based on the collision test process.

[0068] In a specific implementation process of this implementation manner, first, the test control unit can obtain the configuration operation data of the operator. Second, based on the configuration operation data, the test control unit obtains the speed and weight of the collision simulation unit. Third, the test control unit sends the obtained speed and weight of the collision simulation unit to the actuator.

[0069] In a specific implementation process of this implementation manner, first, the vehicle control unit can determine whether the deformation data is successfully obtained. Secondly, in response to the failure to successfully obtain the deformation data, the vehicle control unit sends an adjustment request to the test control unit. Thirdly, based on the received adjustment request, the test control unit adjusts the speed and weight of the collision simulation unit, so as to send the adjusted speed and weight of the collision simulation unit to the actuator. Thirdly, based on the adjusted speed and weight of the collision simulation unit, the actuator controls the collision simulation unit to perform a collision test on the collision warning device of the vehicle. Thirdly, based on the result of the collision test, the collision warning device determines the adjusted deformation data. Thirdly, the vehicle control unit obtains the adjusted deformation data and vehicle state data.

[0070] In one case of this specific implementation process, the relative speed of the vehicle and the collision simulation unit can be determined based on the speed of the vehicle and the speed of the collision simulation unit. Based on the relative speed and the weight of the collision simulation unit, the kinetic energy of the collision simulation unit colliding with the collision warning device is calculated, and the deformation data is calculated based on the kinetic energy.

[0071] Exemplarily, the speed of the vehicle can be 0 meters per second (m / s), and the speed of the collision simulation unit can be 3 m / s. The weight of the collision simulation unit can be 10 kilograms. After the collision simulation unit performs a collision test on the collision warning device, the determined deformation data is zero. The collision simulation unit can be adjusted. The speed of the vehicle can still be 0 m / s, and the adjusted speed of the collision simulation unit can be 4 m / s. The adjusted weight of the collision simulation unit can be 12 kilograms, and the determined deformation data can be 5%.

[0072] In one case of this specific implementation process, the vehicle control unit can determine that the deformation data has not been successfully obtained in response to the obtained deformation data being a preset value. Furthermore, the vehicle control unit can determine that the deformation data has been successfully obtained in response to the obtained deformation data being greater than the preset value.

[0073] In the specific implementation process, the preset value can be zero.

[0074] It can be understood that when the deformation data of the collision warning device is zero, it can indicate that the collision warning device has not deformed after the collision simulation unit collides with it.

[0075] Optionally, in a possible implementation manner of this embodiment, after step 101, further, first, the vehicle control unit may further obtain the initial alarm parameters of the collision alarm device. Secondly, the vehicle control unit determines whether the deformation data and the initial alarm parameters meet the second safety collision condition. Thirdly, in response to the deformation data and the initial alarm parameters not meeting the second safety collision condition, the vehicle control unit performs calibration processing on the initial alarm parameters based on the deformation data. Thirdly, the vehicle control unit uses the result of the calibration processing as the alarm parameters of the collision alarm device.

[0076] In this implementation manner, the second safety collision condition may be that the deformation data is greater than or equal to the initial alarm parameters.

[0077] In a specific implementation process of this implementation manner, in response to the deformation data and the initial alarm parameters meeting the second safety collision condition, the vehicle control unit may use the initial alarm parameters as the alarm parameters of the collision alarm device.

[0078] In this implementation manner, the initial alarm parameters may be the alarm deformation threshold of the collision alarm device pre-configured when the vehicle leaves the factory.

[0079] It should be noted that the specific implementation process provided in this implementation manner may be combined with the multiple specific implementation processes provided in the foregoing implementation manner to implement the vehicle collision alarm test method of this embodiment. For a detailed description, reference may be made to the relevant content in the foregoing implementation manner, which will not be elaborated here.

[0080] Optionally, in a possible implementation manner of this embodiment, in step 104, in response to the vehicle state data not meeting the first safety collision condition, the vehicle control unit adjusts the deformation data based on the vehicle state data according to a preset adjustment coefficient, and calibrates the result of the adjustment processing as the alarm parameters of the collision alarm device.

[0081] In a specific implementation process of this implementation manner, the preset adjustment coefficient may be multiplied by the deformation data to obtain the result of the adjustment processing.

[0082] Here, the preset adjustment coefficient may be determined according to the actual installation position of the collision alarm device. The value range of the preset adjustment coefficient is [0, 1].

[0083] It can be understood that when the vehicle state data does not meet the first safety collision condition, the deformation data may be adjusted to a value smaller than the deformation data, that is, the deformation data is adjusted downward.

[0084] For example, when the deformation data is 5%, and the vehicle state data does not meet the first safety collision condition, the deformation data can be adjusted to 3%. In this way, the deformation sensitivity of the collision warning device can be improved.

[0085] Figure 2 is a schematic structural diagram of a vehicle collision warning test system provided by another embodiment of the present application, as Figure 2 shown. In this embodiment, the vehicle collision warning test system can be used to execute the vehicle collision warning test method in the foregoing embodiment.

[0087] The collision simulation unit can be used to perform a collision test process on the collision warning device.

[0088] The collision warning device can be used to send the deformation data of the collision warning device to the vehicle control unit.

[0090] Optionally, in a possible implementation manner of this embodiment, the vehicle collision warning test system further includes a test control unit and an actuator, and the test control unit is communicatively connected to the actuator. Among them,

[0091] The test control unit can be used to send the speed and weight of the collision simulation unit to the actuator.

[0095] Optionally, in a possible implementation of this embodiment, specifically, the vehicle control unit may also be used to determine whether the deformation data is successfully obtained, and in response to the failure to successfully obtain the deformation data, send an adjustment request to the test control unit.

[0096] The test control unit may also be used to perform adjustment processing on the speed and weight of the collision simulation unit based on the received adjustment request, so as to send the adjusted speed and weight of the collision simulation unit to the actuator.

[0097] The actuator may also be used to control the collision simulation unit to perform a collision test on the collision warning device of the vehicle based on the adjusted speed and weight of the collision simulation unit.

[0098] The collision warning device may also be used to determine the adjusted deformation data based on the result of the collision test.

[0099] The vehicle control unit may also be used to obtain the adjusted deformation data and vehicle state data.

[0100] Optionally, in a possible implementation of this embodiment, the vehicle control unit may also be used to obtain the initial alarm parameters of the collision warning device, determine whether the deformation data and the initial alarm parameters meet the second safe collision condition, and in response to the deformation data and the initial alarm parameters not meeting the second safe collision condition, perform calibration processing on the initial alarm parameters based on the deformation data, and the vehicle control unit uses the result of the calibration processing as the alarm parameters of the collision warning device.
