Fig. 1 shows a flowchart of a vehicle search method applied to a vehicle starting device according to an aspect of the present application, and the method includes: step S11 to step S15,
in step S11, determining a first position of the vehicle in the parking lot by the vehicle-starting device positioning; here, the vehicle starting apparatus has a positioning function, for example, the current position of the vehicle starting apparatus can be determined by GPS of the vehicle starting apparatus, and in a preferred embodiment, the vehicle apparatus is a vehicle key, and when the user gets off the vehicle, the vehicle key is used to lock the door and position the vehicle at the parking lot as the first position of the vehicle.
In step S12, determining a second position where the vehicle starting apparatus is currently located; here, when the user leaves the parking lot with the vehicle startup device, the second location may be a location where the user last stopped or a location where the user returns to the parking lot again, such as a location where the user arrives at a company at a location of the company after parking or a location where the user arrives at an entrance of the parking lot when returning to the parking lot.
Next, in step S13, a moving path of the vehicle starting device from a first position of the vehicle in the parking lot to a second position where the vehicle starting device is currently located is obtained, and a distance between the vehicle starting device and the vehicle is determined based on the moving path of the vehicle starting device; the moving path from the second position to the first position is determined according to the first position where the vehicle is located when the user gets off the vehicle and the second position where the vehicle starting device is located after the user leaves the parking lot, and therefore the distance between the vehicle starting device and the vehicle is calculated based on the moving path, and the path from the current position to the vehicle parking position is planned for the user.
Subsequently, in step S14, a vehicle finding path is generated based on the distribution information of the parking lot and the distance between the vehicle starting apparatus and the vehicle; here, the distribution information of the parking lot may include parking distribution information of current vehicles of the parking lot and structural distribution information of roads and buildings of the parking lot, such as the number and locations of entrances of the parking lot, passable path information of the interior of the parking lot, and the like. And generating a vehicle searching path from the current position to the vehicle parking position for the user according to the distribution information of the parking lot and the determined distance between the vehicle starting equipment and the vehicle.
Finally, in step S15, in response to the vehicle-starting apparatus moving along the vehicle-finding path, a real-time distance between the vehicle-starting apparatus and the vehicle is prompted. The vehicle starting device can prompt the user through voice, the user moves according to the vehicle searching path prompted by the voice, the vehicle starting device can prompt the current distance between the user and the vehicle in real time, and the user can conveniently and quickly search the vehicle.
In an embodiment of the application, parking places where vehicles are parked are different, methods for determining the first position of the vehicle in the parking lot are different, and a calculation mode corresponding to the parking places is adopted for specific parking places, so that the problem of searching the vehicles in complex environments is solved.
Specifically, in step S11, when the parking lot is a first parking lot, the vehicle is located at a first position of the first parking lot based on the door lock instruction information sent to the vehicle by the vehicle starting apparatus. Here, when the parking lot where the vehicle is located is the first parking lot, which is the ground parking lot, the GPS signal is present. When a user parks the vehicle in an overground parking lot, the door is locked after getting off, the current position of the user is determined by the vehicle key through GPS positioning, and then the first position where the vehicle is parked is recorded. When the user enters the parking lot again, the second position where the current vehicle key is located by the GPS, and the distance between the vehicle key and the vehicle is determined according to the second position and the originally recorded first position of parking. When a user gets off the vehicle, the parking lot parking position number can be obtained through the vehicle key, so that a data basis is conveniently provided for the follow-up generation of the vehicle searching path, the more accurate vehicle searching path is generated, and the user can find the vehicle parking position more accurately.
In step S15, the vehicle-starting apparatus transmits ultrasonic information to the vehicle; and receiving ultrasonic information fed back by the vehicle, and prompting the real-time distance between the vehicle starting equipment and the vehicle. The vehicle starting device sends ultrasonic information to the vehicle when the vehicle is continuously moved to the vehicle according to the generated vehicle searching path, the vehicle returns ultrasonic waves to the vehicle starting device to measure the real-time distance between the vehicle starting device and the vehicle, the relative orientation information of the vehicle relative to the vehicle starting device can be determined through the ultrasonic waves, for example, when a user enters a parking lot through different parking lot inlets, the generated vehicle searching path is different due to the fact that the relative orientation of the vehicle is different, the vehicle searching path can be continuously adjusted and the user is prompted to move by combining the ultrasonic information, and the current orientation and the distance between the user and the vehicle are prompted in real time.
Continuing with the above embodiment, in step S15, in response to the vehicle-starting apparatus moving, movement change information and relative orientation information between the vehicle-starting apparatus and the vehicle are determined; and prompting the real-time distance between the vehicle starting equipment and the vehicle according to the movement change information and the relative direction information. The distance between the vehicle starting device and the vehicle is determined according to the parking position (first position) of the vehicle and the current position (second position) of the vehicle starting device, the relative orientation information of the vehicle starting device and the vehicle can also be determined, the current position of the vehicle starting device and the original parking position of the vehicle are determined through GPS, and the generated vehicle searching paths are different because a user enters through different entrances when possibly entering the parking lot again. And continuously updating the real-time distance between the vehicle starting device and the vehicle by combining the relative orientation information so as to generate an optimal vehicle searching path.
In still another embodiment of the present application, in step S11, when the parking lot is a second parking lot, the first position and parking floor information of the vehicle in the second parking lot are determined by the vehicle starting apparatus. Here, the second parking lot is an underground parking lot, and when the vehicle is parked in the underground parking lot, it is necessary to determine position information (latitude and longitude information) of the vehicle and parking floor information (vertical height information) to determine a parking position condition of the vehicle in the underground space.
Specifically, when a vehicle is parked in an underground parking lot, a first position of the vehicle and parking floor information are determined, and a current second position of the vehicle starting equipment can be determined through positioning; determining a moving path of the vehicle starting device from a vehicle parking position to the second position where the vehicle starting device is located currently based on the gyroscope of the vehicle starting device; determining the distance between the vehicle starting device and the vehicle according to the moving path of the vehicle starting device; determining a first position of the vehicle in the second parking lot based on a second position where the vehicle starting device is located currently and a distance between the vehicle starting device and the vehicle; the parking floor information of the vehicle at the second parking lot is determined by analyzing the moving path of the vehicle starting apparatus. After the user arrives at the ground space, the vehicle starting device determines the last stopping position at the last stopping position of the user by using GPS positioning, namely, the second position where the vehicle starting device is located is determined by positioning, and the gyroscope of the vehicle starting device records the position moving path from the vehicle parking position to the second position of the user, so that the distance between the vehicle starting device and the vehicle can be calculated. Then, the GPS position of the vehicle is calculated according to the second position where the vehicle starting device is currently located and the moving path, and the moving path is analyzed to determine specific parking floor information of the vehicle parked in the parking lot, for example, the specific parking floor information can be determined according to a vertical movement track of a gyroscope.
In connection with the above embodiment, the vehicle starting device may further send ultrasonic information to the vehicle through the vehicle starting device when the vehicle starting device reaches the parking floor in response to the vehicle starting device moving along a vehicle finding path; and receiving ultrasonic information fed back by the vehicle, and prompting the real-time distance between the vehicle starting equipment and the vehicle. When the user returns to the parking lot, the vehicle starting device can prompt the user of the parking floor where the vehicle is located, the user can arrive at the vehicle parking floor according to the indication, when the user arrives at the parking floor, the vehicle starting device sends ultrasonic waves to the vehicle, the vehicle returns the ultrasonic waves to the vehicle starting device, and the distance between the vehicle starting device and the vehicle is measured so as to adjust the real-time distance. The gyroscope and the ultrasonic wave can record the three-dimensional position of the vehicle and the travelling path of the user, the vehicle starting equipment integrates the travelling path and the position of the vehicle to obtain the optimal vehicle searching navigation path of the user, and the vehicle can be quickly searched. In addition, when the user returns to the underground parking lot, a plurality of entrances may exist, the relative orientation information between the vehicle starting device and the vehicle when the user arrives at the underground parking lot needs to be determined, the relative orientation can be judged according to the ultrasonic waves, and therefore the optimal vehicle searching path can be generated according to the determined distance between the vehicle starting device and the vehicle and the relative orientation information.
