It should be noted that the driving in the present embodiment latches, controller 200 and the driving hereinafter device that latches are one
It causes.In addition, driving provided in an embodiment of the present invention latches, the executing subject of method can be the integrated embodiment of the present invention and provide
Driving latch the vehicle of functional module, be also possible to driving and latch device, be not especially limited in embodiments of the present invention.
It is understood that above-mentioned scene is only a Sample Scenario provided in an embodiment of the present invention, the embodiment of the present invention
It is not limited to this scene.
With reference to the accompanying drawing, by embodiment come the tool of the present invention will be described in detail embodiment middle rolling car latches method and apparatus
Body implementation.
It referring to fig. 2, is a kind of flow diagram for the method that latches of driving a vehicle provided in an embodiment of the present invention.This method specifically may be used
To include:
Step 201, the current vehicle speed of the vehicle is determined according to the location information of vehicle.
It is understood that the location information of vehicle is the location receivers Real-time Feedback on vehicle, then, a kind of feelings
Under condition, which can be the location receivers with positioning function being directly installed on vehicle；Another situation
Under, the driving which is also possible to be integrated in the vehicle communication positioning with positioning function on device that latches connects
Receive device.
For example, the location information of vehicle can be global positioning system (English: Global Positioning System,
Referred to as: GPS) acquisition, then, the vehicle or driving latch and have corresponding GPS positioning receiver on device.
In some possible implementations, the location information of the vehicle specifically can be the real-time location coordinates of vehicle,
So, the location information in step 201 according to vehicle determines the current vehicle speed of vehicle, specifically can be according to the nearest default of vehicle
The real-time location coordinates of time feedbacking calculate displacement of the vehicle within the unit time, are denoted as the current vehicle speed of the vehicle.Wherein, in advance
If the time can be it is pre-set based on theoretical knowledge or empirical cumulative, such as 5 seconds, then, step 201 specifically can be with base
In the real-time location coordinates of the preceding internal feedback in 5 seconds at current time, the current vehicle speed of the vehicle is calculated.
As an example, in order to which the current vehicle speed of determining vehicle is more accurately and reliable, in conjunction with wheel speed and can determine
Position information, the common present speed for determining vehicle.When specific implementation, as shown in figure 3, step 201 can specifically include:
Step 301, the positioning speed of the vehicle is determined according to the location information.
When specific implementation, according to the real-time location coordinates of the location information of vehicle, such as vehicle, calculates the vehicle and currently exist
Displacement in unit time is denoted as the positioning speed of the vehicle, i.e., the speed determined according to location information.
Step 302, the travel speed of the vehicle is determined according to the current wheel speed of the vehicle.
It is understood that being equipped with wheel speed sensors on vehicle, for acquiring the wheel speed of vehicle tyre, specifically can be
Magneto-electric type wheel speed sensor or Hall wheel speed sensor.
When specific implementation, which latches device can working as by the wheel speed sensors feedback of CAN bus reading vehicle
Preceding wheel speed, and according between wheel speed and speed conversion relation and current wheel speed, calculate the travel speed of the vehicle, i.e. root
The speed determined according to wheel speed.
Step 303, the current vehicle speed of the vehicle is determined based on the positioning speed and the travel speed.
It, can be according to the traveling speed that the positioning speed and current wheel speed that location information is determined are determined when specific implementation
Degree, determines the current vehicle speed of the vehicle jointly.For example, the average value of positioning speed and travel speed can be taken, as working as front truck
Speed.
Such as: assuming that the current wheel speed for obtaining vehicle is A, and location information of the vehicle in nearly 5 seconds is B at current time,
It is possible to determine that travel speed is f (A), positioning speed is g (B), so as to determine the vehicle based on f (A) and g (B)
Current vehicle speed X=h (f (A), g (B)).Where it is assumed that sail speed be f (A)=18,000 m/hour, positioning speed for g (B)=
22000 ms/hour, h () is function of averaging, then, current vehicle speed X=0.5 (f (A)+g (B))=20,000 ms/hour.
In this way, wheel speed and location information can be integrated, comparatively accurate and reliable current vehicle speed is determined jointly, with
It can in time, accurately carry out driving to latch, wheel speed or location information inaccuracy is avoided to cause to be not carried out what driving latched
Problem improves the security performance of vehicle so that reducing vehicle a possibility that security risk occurs.
As another example, on the basis of ensuring the current vehicle speed of determined vehicle, in order to save computing resource, letter
Change driving to latch the operation of middle determining current vehicle speed, the embodiment of the present invention specifically can also be as shown in Figure 4, comprising:
Step 401, judge whether location information meets preset condition, if satisfied, thening follow the steps 402, otherwise, execute step
Rapid 403~step 404.
Wherein, preset condition, specifically can be it is pre-set, for judging the effective critical condition of location information.Such as
Fruit location information meets preset condition, it is believed that the location information of vehicle can accurately determine the current of the vehicle
Speed, i.e., without combining current wheel speed to determine the present speed of vehicle on the basis of location information；If location information is discontented
The foot preset condition can not determine vehicle according to the location information it may be considered that the location information of vehicle is failure state
Present speed, it is possible to determine the current vehicle speed of the vehicle by the current wheel speed for acquiring vehicle.
In an example, which can be the signal strength threshold of pre-set location information, then, step
Rapid 401 specifically may determine that whether the signal strength of the location information of vehicle is greater than signal strength threshold, if it is greater, then thinking
Location information is the stronger available information of signal strength, that is, may be regarded as location information and meet preset condition；Otherwise, if less
In, then it is assumed that location information is the weaker unavailable information of signal strength, that is, may be regarded as location information and be unsatisfactory for preset condition.
In another example, which can also be with pre-set positioning information update threshold speed；So, it walks
Rapid 401 specifically may determine that whether the current renewal speed of the location information of vehicle is greater than renewal speed threshold value, if it is greater, then
Think that location information to update faster available information, that is, may be regarded as location information and meet preset condition；Otherwise, if less
In, then it is assumed that location information be update slower unavailable information (such as be likely to occur Caton or other the problem of)
It is regarded as location information and is unsatisfactory for preset condition.
It should be noted that in some environments, it is also possible to can not be positioned for vehicle, that is, location receivers
The location information of vehicle can not be received, at this point it is possible to which the location information for being regarded as vehicle is unsatisfactory for preset condition, executes step
403~step 404.
Step 402, the current vehicle speed of the vehicle is determined according to the location information of vehicle.
Such as: assuming that the location information of vehicle meets preset condition, and the location information in nearly 5 seconds of current time is
B, it is possible to determine the present speed X=g (B)=22,000 m/hour of vehicle.
Step 403, the current wheel speed of wheel speed sensors acquisition is obtained；
Step 404 determines corresponding travel speed according to the current wheel speed, is denoted as the current vehicle speed of the vehicle.
Wherein, which latches and can be communicated by CAN bus between device and the wheel speed sensors of vehicle, realizes
Collected current wheel speed is sent to the driving by CAN bus by data interaction, the wheel speed sensors that specifically can be vehicle
Latch device.
Such as: assuming that the location information of vehicle is unsatisfactory for preset condition, that is, current location information is unavailable, then, working as
At the preceding moment, the current wheel speed for obtaining the vehicle of wheel speed sensors acquisition is A, may thereby determine that out that the corresponding travel speed of A is f
M/hour, and the current vehicle speed X=f (A)=18,000 m/hour of the vehicle determined by being denoted as (A)=18,000.
It should be noted that when the location information of vehicle is unsatisfactory for preset condition or can not obtain location information, no
The current vehicle speed that the vehicle can be only determined by obtaining the current wheel speed of wheel speed sensors acquisition, can also pass through other and vehicle
The information of the relevant sensor acquisition of speed determines the current vehicle speed of vehicle, is not especially limited in the present embodiment.
It is understood that the current vehicle speed no matter determined according to the corresponding example of Fig. 3, according further to step in Fig. 4
402 or after step 403~step 404 determines the current vehicle speed of vehicle, it can execute following step 202, that is, step
402, after step 404 or step 303, step 202 can be executed.By determining current vehicle speed you can learn that vehicle is worked as
Preceding driving states have accomplished fluently data basis for the subsequent execution driving operation that latches.
Step 202, if the current vehicle speed reaches the default threshold value that latches, the finger that latches is sent to car body control module BCM
It enables, so that BCM control central controlled lock latches to car door.
It is understood that the default threshold value that latches, be it is pre-set, for judge whether to driving latch it is critical
Condition.If the current vehicle speed determined in step 201 reaches the default threshold value that latches, it may be considered that the running speed that vehicle is current
Comparatively fast, it needs to trigger and latch；It, then can be with, whereas if the default threshold value that latches has not yet been reached in the current vehicle speed determined in step 201
Think that the current running speed of vehicle is also slow, latches without triggering.
Wherein, in order to be suitable for different application scenarios, which can be arrived different by flexible setting
Gear (including: 20,000 ms/hour, 30,000 ms/hour, 40,000 ms/hour, 50,000 ms/hour, 70,000 ms/hour etc.), for example, for racing car,
70,000 ms/hour can be set by the default threshold value that latches；For another example have the private car of baby for family, it can be pre- by this
If the threshold value that latches is set as 20,000 ms/hour.It latches existing for the vehicle of function in this way, latching when can make up factory with driving
The problem of condition is single, is unable to satisfy different user demands.
In some implementations, the default threshold value that latches of setting, which specifically may is that be arranged in response to threshold value, instructs, will be described
The target that the carries threshold value that latches is set as the default threshold value that latches in threshold value setting instruction.
In a kind of situation, user, manager or the operation maintenance personnel of vehicle can according to the actual situation, in car-mounted terminal or
In the mobile client that person interacts with vehicle, setting target latches threshold value, then, car-mounted terminal or the movement interacted with vehicle
Client then can be generated carry the target latch threshold value threshold value setting instruction, vehicle by parse the threshold value setting instruction,
It obtains target to latch threshold value, sets the target for the default threshold value that latches of the vehicle and latch threshold value.
In another case, technical staff can be in performance of the server end according to vehicle or vehicle driving region, row
The conditions such as road conditions are sailed, for vehicle is flexible, dynamic setting target latches threshold value, then, which, which then can be generated, takes
It latches the threshold value setting instruction of threshold value with the target, vehicle obtains target and latches threshold value by parsing threshold value setting instruction, will
The default threshold value that latches of the vehicle is set as the target and latches threshold value.
When specific implementation, the current vehicle speed determined by determine reaches the default threshold value that latches, it is believed that vehicle is current
Running speed is very fast, needs to trigger latching, at this point it is possible to generate the instruction that latches, and the instruction that latches is sent by CAN bus
Give car body control module BCM；The BCM is received latch instruction after, according to this latch instruction control central controlled lock car door is fallen
Lock, to ensure the security of the lives and property of driver and passenger.
Conversely, when determining the not up to default threshold value that latches of identified current vehicle speed, it may be considered that the row that vehicle is current
Vehicle speed is slower, and the consumption in order to facilitate user and reduction to lock access times latches without triggering.
In some implementations, in order to improve user experience, if car door has carried out the operation that latches, BCM can also be given birth to
At latch success message and to the driving latch device feedback；When receive BCM feedback latch success message after, may be used also
The success message that latches is fed back to server and/or user client, so that server or user know to work as front truck
Vehicle door status be to latch state.
In addition, accident occurs or car door, the present embodiment can be opened when having specific demand after latching in order to ensure car door
It can also include: the unlocking command in response to server or user client, operation is unlocked to the car door of the vehicle.
In this way, a key can not be carried out when accident occurs by latching when can solve factory with driving existing for the vehicle of function
The problem of unlock, cause driving to latch security risk that function becomes bigger instead.
As it can be seen that through the embodiment of the present invention, the current vehicle speed of the vehicle can be determined according to the location information of vehicle, when true
Determine current vehicle speed and reach the default threshold value that latches, then send the instruction that latches to car body control module BCM, so that BCM controls central controlled lock
It latches to car door.As it can be seen that using the method that latches provided in an embodiment of the present invention of driving a vehicle, it can be for example, by global positioning system
The GPS etc. that unites obtains the location information of vehicle in real time, to determine the current vehicle speed of vehicle according to location information, and to current vehicle speed
Size judgement is carried out with the default threshold value that latches, once current vehicle speed reaches the default threshold value that latches, then it is assumed that it needs to work as front truck
The vehicle of speed traveling carries out driving and latches, to realize latching automatically for vehicle.Thus it is possible, on the one hand, being fallen automatically for not having
The vehicle of lock function, it is easy, effective to provide a kind of function that accurately latches；On the other hand, for having the function that latches automatically
The vehicle of energy can not only read the condition that speed latches as triggering by wheel speed or instrument board, can also be with positioning
The condition that the speed that information determines latches as triggering, is equivalent to and is additionally arranged " dual fail-safe " for the function that latches automatically, when this has
Automatically latch function vehicle latch failure (such as: can not by wheel speed or instrument board reading speed) when, it is ensured that vehicle
The operation that latches still can be completed automatically and accurately, effectively avoid causing since car door does not latch when driving
