In this embodiment, the sensing sensor is used to acquire data information required by the vehicle, wherein the sensing sensor may include:

cameras, laser radars, millimeter wave radars, ultrasonic radars, gyroscopes, and accelerometers. For example, the data information of the target parking space is acquired through a perception sensor of the vehicle, so that the vehicle can analyze the data information of the target parking space, and the vehicle is subjected to path planning according to the obstacle data information within the preset range of the vehicle acquired by the vehicle sensor, so that the vehicle can be determined to avoid the obstacle data information or the target parking space is determined again, and further, the vehicle can be guaranteed to smoothly run to the target parking space before the vehicle does not run.

And S102, determining parking position information in the target parking space according to the data information of the target parking space and the data information of the vehicle.

For example, the controller of the vehicle can calculate the parking position information in the target parking space according to a preset algorithm through the data information of the target parking space and the data information of the vehicle itself. In this embodiment, it can be seen from the schematic diagram of the parking position information in the target parking space shown in fig. 2 that the vehicle can acquire the data information of the target parking space in the process of passing through the whole target parking space. For example, in the figure, the vehicle may acquire data information of the target parking space in the process of traveling from point a to point B, and determine parking position information in the target parking space by combining the data information of the vehicle itself.

S103, determining initial parking position information of the vehicle according to the parking position information and the obstacle data information in the preset range of the vehicle.

For example, referring to fig. 2, in a case where parking position information within a target parking space is determined and there is no obstacle information within a preset range of the vehicle, initial parking position information of the vehicle may be determined. If the obstacle data information within the preset range is on the preset parking path of the vehicle, the data information of the new target parking space is determined again.

For example, sensor assembly 914 may detect an open/closed state of device 900, the relative positioning of components, such as a display and keypad of device 900, the change in position of device 900 or a component of device 900, the presence or absence of user contact with device 900, the orientation or acceleration/deceleration of device 900, and the change in temperature of device 900. The sensor assembly 914 may include a proximity sensor configured to detect the presence of a nearby object in the absence of any physical contact. The sensor assembly 914 may also include a light sensor, such as a CMOS or CCD image sensor, for use in imaging applications. In some embodiments, the sensor assembly 914 may also include an acceleration sensor, a gyroscope sensor, a magnetic sensor, a pressure sensor, or a temperature sensor.

The communication component 916 is configured to facilitate communications between the apparatus 900 and other devices in a wired or wireless manner. The apparatus 900 may access a wireless network based on a communication standard, such as WiFi, 2G or 3G, or a combination thereof. In an exemplary embodiment, the communication component 916 receives a broadcast signal or broadcast associated information from an external broadcast management system via a broadcast channel. In an exemplary embodiment, the communication component 916 further includes a Near Field Communication (NFC) module to facilitate short-range communications. For example, the NFC module may be implemented based on Radio Frequency Identification (RFID) technology, infrared data association (IrDA) technology, Ultra Wideband (UWB) technology, Bluetooth (BT) technology, and other technologies.

In an exemplary embodiment, the apparatus 900 may be implemented by one or more Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), controllers, micro-controllers, microprocessors or other electronic components for performing the above-described methods.

In an exemplary embodiment, a non-transitory computer readable storage medium comprising instructions, such as the memory 904 comprising instructions, executable by the processor 920 of the apparatus 900 to perform the above-described method is also provided. For example, the non-transitory computer readable storage medium may be a ROM, a Random Access Memory (RAM), a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like.

A non-transitory computer-readable storage medium, in which instructions are executed by a processor of a terminal device, so that the terminal device can perform the method of initial parking location information determination of the terminal device.
