it can be understood that the first preset speed is a preset value, and the specific value thereof is not limited, and can be set according to actual conditions and needs. Preferably, in the present embodiment, the first preset speed is preferably 3 Km/h. Further, after the vehicle starts the engine to enter the initial mode, the vehicle is in a stationary state immediately after the engine is started, or in an initial starting state, and the speed of the vehicle is lower than a first preset speed, generally between 0.5Km/h and 1Km/h, and preferably 0.5Km/h in the embodiment.

and S112, judging whether the running speed of the vehicle in the running mode is changed from being smaller than the first preset speed to being larger than a third preset speed, and executing a step S114 if the running speed of the vehicle in the running mode is changed from being smaller than the first preset speed to being larger than the third preset speed.
Specifically, the step S112 of determining whether the running speed of the vehicle in the running mode changes from being smaller than the first preset speed to being larger than a third preset speed specifically includes:
s1120 detects a traveling speed of the vehicle in a traveling mode;
specifically, the method for detecting the driving speed of the vehicle in the driving mode in this step may refer to the detailed description of step S100, and the method is similar, but is only based on different driving modes, and is not repeated here.
S1122, determining whether the detected driving speed of the vehicle in the driving mode is less than a first preset speed, and if the detected driving speed of the vehicle in the driving mode is less than the first preset speed, performing step S1124.
S1124, continuously detecting the running speed of the vehicle in the running mode;
and S1026, judging whether the running speed of the vehicle in the running mode continuously detected is greater than a third preset speed, wherein the first preset speed is less than the second preset speed and less than the third preset speed, and executing the step S114 if the running speed of the vehicle in the running mode continuously detected is greater than the third preset speed.
It can be understood that, similar to the first preset speed and the second preset speed, the third preset speed is also a preset value, and a specific value thereof is not limited, and can be set according to actual conditions and needs. Preferably, in the present embodiment, the third preset speed is preferably 20 Km/h. Specifically, when the running speed of the vehicle in the running mode is continuously detected and it is determined that the running speed of the vehicle in the running mode continuously detected is greater than a third preset speed, it indicates that the running speed of the vehicle changes from being less than the first preset speed to being greater than the third preset speed, that is, changes from being less than 3Km/h to being greater than 10Km/h, and meets the triggering condition of key search, and executes a key search to avoid the key passing through the window.
S114, executing key search once, and updating the target times m of the vehicle key search in the driving mode;
specifically, after the key search condition is met, a key search is executed, and the target number m of vehicle key searches in the driving mode is updated, where updating the target number m of vehicle key searches in the driving mode specifically includes: and after one key search is executed, circularly adding 1 to the target number m of the vehicle key search in the driving mode, namely the target number m of the vehicle key search in the updated driving mode is the same as the total number of the key search executed in the driving mode, wherein m is 0, 1, 2 and 3.
S116, judging whether the target frequency M of the vehicle key search in the driving mode reaches a second preset search frequency M or not, executing the step S118 if the target frequency M of the vehicle key search in the driving mode reaches the second preset search frequency M, and returning to the step S112 if the target frequency M of the vehicle key search in the driving mode does not reach the second preset search frequency M, wherein M is 0, 1, 2 and 3.
S118, switching the vehicle key searching system from a driving mode to a traffic jam mode, clearing the target number m of vehicle key searching, and suspending the vehicle key searching.
Specifically, when the target number M of times of vehicle key search in the driving mode reaches a second preset number M of times of search, the vehicle key search system is switched from the driving mode to the traffic congestion mode, preferably, in this embodiment, the second preset number M of times of search is preferably 8, and when the number M of times of key search in the updated initial mode is 8, the mode switching condition is satisfied, and the vehicle key search system is switched from the driving mode to the traffic congestion mode. Subsequently, the target number of times 8 of the vehicle key search that is finally updated in the driving mode is cleared.
It can be understood that, in order to more accurately determine that the vehicle is in the traffic jam state, whether the target number M of times of the vehicle key search in the driving mode reaches the second preset search number M may be determined within a certain preset time threshold. Preferably, the preset time threshold is set to 15min, the second preset search frequency M is set to 8, and when the target frequency M of the vehicle key search reaches 8 times within the 15min, it indicates that the vehicle is in a frequent start-stop state, and the vehicle is in a traffic jam mode. Through the limitation of time, the misjudgment of the traffic jam state can be avoided when the vehicle target searching times m reach the second preset time for too long time. It can be understood that, when the vehicle driving state is the traffic jam state, if the key search is still executed, the number of times of triggering the key search is frequent, and the loss of the key electric quantity is easily caused.
Further, step S118, switching the vehicle from the driving mode to the traffic congestion mode, clearing the target number m of vehicle key searches, and suspending the vehicle key search, and then:
s120, detecting the running speed of the vehicle in the traffic jam mode;
specifically, the method for detecting the driving speed of the vehicle in the traffic jam mode in this step may refer to the detailed description of step S100, and the method is similar, but is only based on different driving modes, and is not repeated here.
S122, determining whether the driving speed of the vehicle in the detected traffic congestion mode is greater than a fourth preset speed, and if the driving speed of the vehicle in the detected traffic congestion mode is greater than the fourth preset speed, executing step S124.
And S124, judging whether the time that the vehicle continuously runs at the running speed in the detected traffic jam mode is longer than the preset time or not, if so, executing the step S126 and returning to the step S110. At this time, the vehicle key search system is switched from the traffic jam mode to the driving mode.
And S126, switching the vehicle key searching system from a traffic jam mode to a driving mode.
It is understood that the fourth preset speed is also a preset value, and the preset time is also a preset value, preferably, in this embodiment, the fourth preset speed is preferably 40Km/h, and the preset time is preferably 5min, when the driving speed of the vehicle in the traffic jam mode is detected to be greater than the fourth preset speed, that is, greater than 40Km/h, and the vehicle continues to drive at the detected driving speed for the preset time and for 5min, it indicates that the road is no longer congested, and the frequent starting and stopping states of the vehicle are eliminated, at this time, the vehicle may be switched from the traffic jam mode to the driving mode, and the key search is continuously performed.
It will be appreciated that the method may also be performed from the initial mode after determining that the vehicle has experienced a congestion condition, by shutting down the engine and starting the engine again.
