As Figure 1-Figure 4, first aspect present invention embodiment provides a kind of control method of car key system, application
In car key.
Firstly the need of explanation, key is divided into several different energy saver modes by this programme, is respectively:
Operating mode:Key can respond push button signalling, low frequency signal and detection motor message, simultaneously for low frequency signal energy
Enough feed back high-frequency signal;
First static schema:Key can respond push button signalling, low frequency signal, not detect motor message, while will not be to low frequency
Signal is to feed back high-frequency signal;
Second static schema:Key can respond push button signalling, low frequency signal, not detect motor message, while will not be to low frequency
Signal is to feed back high-frequency signal;
Interior low-power consumption mode:Key can respond low frequency signal periodically, not detect push button signalling and motor message, while not
To low frequency signal to feed back high-frequency signal;
The outer low-power consumption mode of vehicle:Key can detect motor message and push button signalling, not detect low frequency signal, not send high frequency letter
Number.
Super low-power consumption pattern:Key is merely able to detection push button signalling, remaining function is closed.
Its function for reaching of i.e. a variety of different patterns is different, and the power of consumption is also different.
When key is located at car, judge whether to detect the low frequency signal that vehicle control device is sent out;The low frequency signal
Including speed information;
If detecting low frequency signal and speed being not more than given threshold, enter operating mode;
If detecting low frequency signal and speed being more than given threshold, into the car low-power consumption mode;
If can't detect low frequency signal, enter the first static schema;
It is in order to be confirmed whether to have key, i.e., in PKE that wherein vehicle control device, which sends out low frequency signal,(Passive Keyless
Entry:Keyless entry)Or PKS(Passive Keyless Start:No key starts)When, vehicle control device needs to send out
A low frequency signal is sent, a high-frequency signal can be fed back when key receives the low frequency signal, vehicle control device receives this
High-frequency signal confirms there is key, at this time can one-key start or keyless entry.It is to be based on for the considerations of speed
When vehicle is usually that key need not can be made to enter an interior low-power consumption mould at this time using key is arrived in the process of moving
Formula, when speed is less than some velocity amplitude, i.e. the possible This vehicle stops frequently of car owner has demand, i.e., to speed at this point for key
Degree one given threshold of setting, when speed is more than the given threshold, key i.e. low-power consumption mode into the car, when speed is little
When given threshold, key enters operating mode.Wherein low frequency signal is controlled by vehicle control device and is sent, can be by interior antenna
Or it is sent by the vehicle outside antenna of vehicle outer door handle.
When key is located at outside vehicle, judge whether to detect low frequency signal or push button signalling;
If detecting low frequency signal or push button signalling, enter operating mode;
If can't detect low frequency signal or push button signalling, enter the second static schema.
What needs to be explained here is that when needing using PKE functions, vehicle control device can send a low frequency signal, should
Low frequency signal is usually when key is close to door handle for vehicle, and to be incuded by the vehicle outside antenna transmission positioned at door handle for vehicle position
To low frequency signal, then key sends a high-frequency signal and feeds back to vehicle control device, and vehicle control device receives high-frequency signal i.e.
Confirmation has key, at this time unlocks car door, that is, completes keyless entry.So also needing to consider whether when outside vehicle
Low frequency signal can be received, simultaneously, it is contemplated that key usually needs to lock vehicle or unlock vehicle etc. in outside vehicle
Operation, these are usually to need button operation, so when key is in outside vehicle, it is also necessary to push button signalling are detected, if detection
To low frequency signal or push button signalling, then enter operating mode, the second static schema is entered if it both can't detect.
Key is located at both of these case outside interior or vehicle to be distinguish, in the car when, while considering speed
Information, when detecting that low frequency signal and speed are not more than given threshold, into operating mode, when detecting low frequency signal and vehicle
Speed is more than given threshold, then low-power consumption mode enters the first static schema if can't detect low frequency signal into the car,
When for key outside vehicle, while being additionally contemplates that push button signalling.By the comprehensive descision of multi-aspect information, enable its pattern switching
It is enough more intelligent, it is more quick for demand response, while also ensureing to reduce the requirement of power consumption as far as possible.
Further, when key is in car, and into the car after low-power consumption mode, key needs to detect low frequency periodically
Signal, when detecting that low frequency signal and speed be not more than given threshold, then the key enters the first static schema.Work as speed
When more than given threshold, key can low-power consumption mode into the car, close some functions to reduce unnecessary power consumption, work as speed
When being reduced to given threshold, vehicle control device can send low frequency signal, when key receives the low frequency signal and from vehicle therein
When judging that speed has been not more than given threshold in fast information, key switchs to operating mode from interior low-power consumption mode.Here it needs
It is noted that since key at this time is to periodically detect low frequency signal, so the low frequency signal transmitted by vehicle control device
Duration be greater than the period, to ensure that key can receive the low frequency signal.
Further, when key is located at outside vehicle, and key is now in the second static schema, if key is default first
Low frequency signal or push button signalling are detected in time, then enter operating mode;When not detected in the first preset time
Low frequency signal or push button signalling then enter the outer low-power consumption mode of vehicle.
Further, after the key enters low-power consumption mode outside vehicle, when detecting movement in the second preset time
Signal, then enter the second static schema, when detecting push button signalling in the second preset time, then enter operating mode, when
Push button signalling or motor message are not detected in second preset time, then enter super low-power consumption pattern.Here function signal is transported
Whether what is indicated is key just in motion state, such as when car owner's carrying keys move, key is to be kept in motion.Work as
Outside into vehicle after low-power consumption mode, push button signalling either motor message is judged whether there is in the second preset time, if there is
Push button signalling, then it represents that car owner has use demand, then key enters operating mode, when detecting motor message, then it represents that key
It is moving, car owner is at any time there is a possibility that with key, then key enters the second static schema, if both not detected that button was believed
It number does not also detect motor message, then enters super low-power consumption pattern.It is right by accurately simulating scene residing for key as far as possible
Key carries out the switching of different mode to achieve the purpose that preferably to reduce power consumption.
Further, after the key enters super low-power consumption pattern, when detecting push button signalling, then enter Working mould
Formula.Otherwise, key persistently keeps super low-power consumption pattern, until there is push button signalling to wake up key.
In the present solution, for it is various it is different in the case of, the pattern of key is different, wakes up the condition of key
It is also different, by rational wake-up condition, can either ensureing that the while of reducing power consumption also can rapidly reach in time
To the function of key itself.
To solve the above-mentioned problems, second aspect of the present invention provides a kind of car key system, such as Fig. 5 and Fig. 6, including vehicle
Controller 200, the high-frequency signal that vehicle control device 200 is used to emit low frequency signal and receive the feedback of key 100;And
Key 100, key 100 include low frequency detection module 102, high-frequency emission module 103, key-press module 104 and control
Module 101, when key 100 is located at car, low frequency detection module 102 judges whether to detect what vehicle control device 200 was sent out
Low frequency signal, if detecting that low frequency signal and speed are not more than given threshold, control module 101 controls key 100 and enters
Operating mode, if detecting that low frequency signal and speed are more than given threshold, control module 101 controls key 100 and enters vehicle
Interior low-power consumption mode, if can't detect low frequency signal, control module 101 controls key 100 and enters the first static schema;When
When key 100 is located at outside vehicle, low frequency detection module 102 judges whether to detect that low frequency signal or the judgement of key-press module 104 are
No to detect push button signalling, if detecting low frequency signal or push button signalling, control module 101 controls key 100 and enters
Operating mode, if can't detect low frequency signal or push button signalling, it is quiet into second that control module 101 controls key 100
Morphotype formula;High-frequency emission module 103 is used to feed back high-frequency signal to vehicle control device 200 when receiving low frequency signal.
Key 100 is located at both of these case outside interior or vehicle and is distinguish by this programme, in the car when, examine simultaneously
Consider speed information, when detecting that low frequency signal and speed are not more than given threshold, the control of control module 101 enters Working mould
Formula, when detecting that low frequency signal and speed be more than given threshold, then low-power consumption mode into the car, if can't detect low frequency letter
Number, then the control of control module 101 enters the first static schema, when for key 100 outside vehicle, while being additionally contemplates that button is believed
Number.By the comprehensive descision of multi-aspect information, keep its pattern switching more intelligent, it is more quick for demand response, together
When also as far as possible ensure reduce power consumption requirement.
Further, after key 100 into the car low-power consumption mode, low frequency detection module 102 detects low frequency periodically
Signal, when detecting that low frequency signal and speed information be not more than given threshold, then key 100 enters the first static schema.Work as vehicle
Speed has been more than given threshold, and vehicle control device 200 can send low frequency signal, and low frequency detection module 102 receives the low frequency signal
And judge speed information therein, when speed is not more than given threshold, then key 100 enters the first static schema.In order to ensure
Low frequency detection module 102 can receive the low frequency signal, and the duration that vehicle control device 200 sends the low frequency signal is more than low frequency
102 detection cycle of detection module.
Further, after key 100 enters the second static schema, if low frequency detection module in the first preset time
102 detect that low frequency signal or key-press module 104 detect push button signalling, then key 100 enters operating mode, otherwise key
100 enter the outer low-power consumption mode of vehicle.
Further, key 100 further includes having motion detection block 105, enters low-power consumption mode outside vehicle in key 100
Afterwards, when in the second preset time motion detection block 105 detect motor message, then key 100 enter the second static schema, when
Key-press module 104 detects push button signalling in the second preset time, then key 100 enters operating mode, when default second
Push button signalling or motor message are not detected in time, then key 100 enters super low-power consumption pattern.
