DETAILED DESCRIPTION OF THE EMBODIMENTS

In the following, the solutions according to the embodiments of the present disclosure will be described clearly and completely with reference to the figures, such that the solutions can be better understood by those skilled in the art. Obviously, the embodiments described below are only some, rather than all, of the embodiments of the present disclosure.

All other embodiments that can be obtained by those skilled in the art based on the embodiments described in the present disclosure without any inventive efforts are to be encompassed by the scope of the present disclosure.

In the related art, in some application scenarios, unmanned vehicles may need to be parked accurately at some specified (or predetermined) positions. However, in these scenarios, there may typically be weak GPS signals or signal interference, such that it would be difficult to achieve accurate position-based parking of unmanned vehicles. In view of this, the embodiments of the present disclosure provide solutions for position-based parking of a vehicle, so as to solve the above problem.

In the solutions according to the embodiments of the present disclosure, a roadside device is provided within a predetermined range from a predetermined position. The roadside device obtains positioning condition data regarding position-based parking of a vehicle at the predetermined position, determines posture data of the vehicle based on the positioning condition data of the vehicle, and transmits the posture data to the vehicle. The vehicle decides whether the posture data satisfies a predetermined positioning rule, and if not, determines posture adjustment data for the vehicle and controls the vehicle to perform a posture adjustment operation based on the posture adjustment data. In this way, the vehicle may be parked at the predetermined position accurately even with a weak GPS signal, thereby solving the problem in the related art that an unmanned vehicle cannot be parked at a specified position accurately in an environment with a weak GPS signal.

The core idea of the present disclosure has been described above. The solutions according to the embodiments of the present disclosure will be described in further detail below with reference to the figures, such that they can be better understood by those skilled in the art and that the above objects, features and advantages of the embodiments of the present disclosure will become more apparent.

The system for position-based parking of a vehicle according to the embodiments of the present disclosure can be applied in various environments such as a coastal port area, a highway port area, a mining area, a warehouse or an industrial park. FIG. 1a is illustrated with reference to an example of a coastal port area. FIG. 1a shows a system for position-based parking of a vehicle according to some embodiments of the present disclosure. The system includes a roadside device 1 and the vehicle 2. The roadside device 1 may be located within a predetermined range B from a predetermined position A. The predetermined position A may be set depending on requirements of application scenarios, e.g., as a loading and unloading position of a crane. The shape and/or size of the predetermined range B may be set depending on requirements of application scenarios, such that the roadside device 1 may monitor the position-based parking condition of the vehicle and communicate with the vehicle 2. The roadside device 1 may be installed at a predetermined height to avoid obstruction by objects or signal interference, thereby monitoring the vehicle 2 or communicating with the vehicle 2 effectively.

FIG. 1b shows a structure of a system for position-based parking of a vehicle according to some embodiments of the present disclosure. As shown, the roadside device 1 includes a sensing device 11, a roadside processing device 12 and a communication device 13. The vehicle 2 includes a vehicle-mounted processing device 21 and a communication device 22.

In the roadside device 1, the sensing device 11 may be configured to obtain positioning condition data regarding position-based parking of the vehicle 2 at the predetermined position A. The sensing device 11 may include at least one camera for obtaining image data of the vehicle and its surrounding environment and/or a laser radar for obtaining point cloud of the vehicle and its surrounding environment. That is, the positioning condition data may include the image data and/or the point cloud data. The sensing device 11 may further include other sensors depending on requirements of specific application scenarios. In this case, the positioning condition data may further include data obtained by the other sensors.

The roadside processing device 12 may be configured to determine posture data of the vehicle based on the positioning condition data of the vehicle. The roadside processing device 12 may process positioning condition data preliminarily to obtain related data, e.g., the posture data of the vehicle, and communicate the related data with the vehicle 2, such that the amount of data to be communicated may be reduced and the processing speed and efficiency at the vehicle may be improved.

The roadside processing device 12 may determine the posture data of the vehicle based on the positioning condition data of the vehicle by performing the following steps.

At step S1, the roadside processing device 12 may simulate a positioning condition of the vehicle on a map based on the positioning condition data of the vehicle.

At step S2, the posture data of the vehicle may be determined based on the positioning condition of the vehicle on the map.

That is, the roadside processing device 12 may locate the image data and/or the point cloud data of the vehicle and its surrounding environment as obtained by the sensing device 11 onto map data, simulate the positioning condition of the vehicle on the map for analysis and obtain the posture data of the vehicle. The specific algorithm used here can be set depending on requirements of specific application scenarios, and the present disclosure is not limited to any specific algorithm.

The posture data of the vehicle may include at least one of: a direction of the vehicle, a position of the vehicle relative to the predetermined position, or a distance between the vehicle and the predetermined position. Depending on requirements of specific application scenarios, the posture data may further include various types of other data, including e.g., a distance between the vehicle body and a lane line, an angle between the vehicle body and a lane line, a tilt angle of the vehicle body, or the like.

The communication device 13 may be configured to transmit the posture data of the vehicle to the vehicle 2. The communication device 13 may use various communication protocols, including e.g., WiFi, 4G or Vehicle to Everything (V2X), to ensure effective communication between the roadside device 1 and the vehicle 2.

In the vehicle 2, the communication device 22 may be configured to receive the posture data from the roadside device, by using the communication protocol corresponding to the protocol used by the communication device 13 in the roadside device.

The vehicle-mounted processing device 21 may be configured to decide whether the posture data satisfies a predetermined positioning rule, and if not, determine posture adjustment data for the vehicle and control the vehicle 2 to perform a posture adjustment operation based on the posture adjustment data. The vehicle-mounted processing device 21 determines that the position-based parking has completed when deciding that the posture data satisfies the predetermined positioning rule.

The operation principles of the vehicle 2 will be explained below.

FIG. 2 is a flowchart illustrating a method for position-based parking of a vehicle according to some embodiments of the present disclosure. The method includes the following steps.

At step 21, during position-based parking of the vehicle at a predetermined position, a communication device of the vehicle receives posture data from a roadside device located within a predetermined range from the predetermined position.

As described above, the communication device of the vehicle may communicate with the roadside device using various communication protocols to obtain the posture data transmitted from the roadside device. The posture data may include at least one of: a direction of the vehicle, a position of the vehicle relative to the predetermined position, or a distance between the vehicle and the predetermined position.

At step 22, a vehicle-mounted processing device of the vehicle decides whether the posture data satisfies a predetermined positioning rule. If so, the method proceeds with step 23; or otherwise the method proceeds with step 24.

For example, the predetermined positioning rule may include:

a) a location of the predetermined position A;

b) a distance between the front of the vehicle and the predetermined position not being larger than 10 cm; and

c) a direction the front of the vehicle faces being within X±Y, where X denotes a direction and Y denotes an offset.

Here, standard positioning data may include: the location of the predetermined position, and the direction the front of the vehicle faces being X.

The posture data of the vehicle may include: the distance between the front of the vehicle and the predetermined position being 1 m, and the direction the front of the vehicle faces being X+Z, where Z is an offset towards a particular direction and Z>Y.

Apparently the posture data of the vehicle does not satisfy the positioning rule.

At step 23, it is determined that the position-based parking has completed and the method ends.

At step 24, posture adjustment data for the vehicle is determined.

Here, the vehicle-mounted processing device 21 may determine the posture adjustment data based on the posture data of the vehicle and the predetermined positioning rule by performing the following steps.

At step Sa, the posture data of the vehicle is compared with the standard positioning data in the predetermined positioning rule to determine a difference between the posture data of the vehicle and the standard positioning data.

At step Sb, the difference is determined as the posture adjustment data for the vehicle.

For example, when the posture data of the vehicle includes the distance between the front of the vehicle and the predetermined position being 1 m and the direction the front of the vehicle faces being X+Z, and the standard positioning data includes the location of the predetermined position and the direction the front of the vehicle faces being X, the posture data of the vehicle and the standard positioning data may be compared to determine the differences between their respective parameters as the posture adjustment data, e.g., the vehicle to move 1 m forward and the angle of the vehicle to be adjusted by −Z.

At step 25, the vehicle is controlled to perform a posture adjustment operation based on the posture adjustment data.

Here, the posture adjustment operation to be performed by the vehicle-mounted processing device may include at least one of: an engine operation, a steering wheel operation, a throttle operation or a brake operation. Other operations can be performed depending on requirements of specific application scenarios.

For example, based on the posture adjustment data including the vehicle to move 1 m forward and the angle of the vehicle to be adjusted by −Z, the posture adjustment operation may include: an engine operation, a steering wheel operation for angle adjustment of −Z, a steering wheel resetting operation, a throttle operation and a brake operation.
