It should be noted that the roadside parking space detection system may determine whether there is an alternative parking space in the roadside parking area at the current time according to a second preset threshold and a size relationship between lengths of the used parking areas. The length of each roadside parking area can be a fixed value, and the second preset thresholds corresponding to different roadside parking areas can be different. The second preset threshold may be equal to λ times the length of the roadside parking area, λ may be equal to 0.9 or 0.8, and λ may also be determined according to an actual situation.

And S1042, determining the alternative parking space corresponding to the minimum distance smaller than a third preset threshold value in all the distances as the target parking space.
Specifically, the third preset threshold may be a distance between the current position of the vehicle and a preset parking candidate, and the third preset threshold may be determined according to the current position of the vehicle and an actual condition of the roadside parking area. If a plurality of distances in all the distances are smaller than a third preset threshold, the roadside parking space detection system may determine the candidate parking space corresponding to the minimum distance as the target parking space.
In this embodiment, if there are two parking spaces around the vehicle, and there is one parking space in each of the two parking areas, and the distance between the parking space and the current position of the vehicle is equal, the roadside parking space detection system needs to determine the target parking space according to the length of the used parking area in the two parking areas, and may determine the parking space in the roadside parking area with the longer length of the used parking area as the target parking space.
According to the roadside parking space detection method provided by the embodiment, each distance between the current position of the vehicle and each alternative parking space is compared with the third preset threshold value by the roadside parking space detection system, and the target parking space is further determined according to the comparison result.

s1043, sequencing the length of each used parking area in the roadside parking area at each historical moment.
Specifically, the roadside parking space detection system may sort each length of the used parking areas in each of the roadside parking areas at each historical time in a descending order.
And S1044, determining the candidate parking space in the roadside parking area corresponding to the minimum length smaller than the fourth preset threshold value in all the lengths as the target parking space.
Specifically, the fourth preset threshold may be a preset length corresponding to an already-used parking area in the roadside parking area, and the fourth preset threshold may be determined according to the actual length of the roadside parking area, the length of the vehicle itself, and the length of the already-used parking area in the roadside parking area at the corresponding historical time. If a plurality of lengths in all lengths are smaller than a fourth preset threshold, the roadside parking space detection system may determine the candidate parking space in the roadside parking area corresponding to the minimum length as the target parking space.
In this embodiment, if there are two roadside parking areas around the vehicle and the lengths of the used parking areas in the two areas are equal, the roadside parking space detection system needs to determine the current position of the vehicle, the distance between the current position of the vehicle and the nearest candidate parking space in the two areas, and determine the candidate parking space corresponding to the minimum distance as the target parking space.
According to the roadside parking space detection method provided by the embodiment, the roadside parking space detection system compares each length corresponding to the used parking area in the roadside parking area with the fourth preset threshold value at each historical moment, and further determines the target parking space according to the comparison result.
In one embodiment, on the basis of the roadside parking space detection method, the method further includes: and acquiring a navigation route according to the target parking space, wherein the navigation route is used for guiding the vehicle to run to the target parking space.
Specifically, if the roadside parking space detection system can use the determined target parking space as the navigation destination, the vehicle-mounted navigation system automatically replans the navigation route, outputs the updated navigation route, and displays the updated navigation route on the vehicle-mounted navigation touch screen interface so as to instruct the user to drive the vehicle to the target parking space according to the updated navigation route.
According to the roadside parking space detection method provided by the embodiment, the roadside parking space detection system can detect the roadside parking area around the vehicle before the vehicle enters the urban road, and search for the alternative parking space in the roadside parking area, so that the target parking space is determined according to the alternative parking space, and the target parking space is taken as the navigation destination, and the navigation route is re-planned, so that the vehicle enters the urban road according to the navigation route until the vehicle stops in the target parking space, thereby avoiding the situation that no idle parking spaces exist on the two sides of the road after the vehicle enters the urban road, and the vehicle needs to be backed and left, and further improving the parking efficiency and user experience of the user.
