A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
As shown in Figure 1, 2, the voice control system closed the door for automobile, including sounding horn, sonification system, master control mould
Block, shutdown state detection module, shutdown state detection module are closed for detecting car door critical localisation whether closed
The critical localisation of door state is the just accessible position of car door and vehicle body at closing time；Shutdown state detection module output end and master control
Module connection, main control module control sonification system according to the shutdown state of detection, then by sonification system driving sounding horn hair
Sound out.Sonification system realizes driving sounding horn using vehicle audio.Main control module is realized using entire car controller.
Entire car controller is when detecting that car door is in shutdown state and reaches the critical localisation of shutdown state, control hair
Sound system driving sounding horn makes a sound.So as to which the sound of car door shutdown is offset or covered by making a sound.Tool
Body can be controlled sounding horn by the modification of software according to actual needs and issue various forms of acoustic signals, thus full
The sound that foot generates closing of the door slackening or covering.
In order to adapt to the car door that is not open to traffic, each car door one sounding horn of corresponding setting and the inspection of corresponding shutdown state
Module is surveyed, each sounding horn corresponding a car door, a shutdown state detection module, entire car controller is according to according to car door pair
The shutdown state detection module answered controls the corresponding loudspeaker of the car door and makes a sound.
Sounding horn is corresponding it can be arranged on B column in two car doors of front door or so, left and right rear door
Corresponding sounding horn is arranged on C column, so that the sound issued is that car door collision place issues for acoustically
's.
Shutdown state detection module includes angular transducer, close to switch, is arranged on the inside of car door close to switch, for examining
For measuring car door at a distance from center body pillar, angular transducer is used for the open and close angle signal of car door, by angle information by greatly to
Small variation is to judge that car door belongs to shutdown state or door opening state.When car door, which is in angle, big become smaller, it may be considered that
Shutdown state.Angular transducer is separately connected entire car controller VCU close to the output end switched, and vehicle VCU passes through angle sensor
When both device, close switches aggregation of data is judged to belong to shutdown state and reach the critical localisation of shutdown, entire car controller is logical
The corresponding loudspeaker of vehicle audio driving car door are crossed to make a sound.This sound can imitate the sound of car door shutdown, provide
The thick and heavy shutdown sound for having texture covers actual door slam, can also be offset by way of reversed sound wave car door noise come
Noise is reduced, NVH quality is improved.
Entire car controller is also connected with the fastening signal that lock catch of door lock is obtained by door lock unit, after the completion of shutdown, sounding list
Member stops occurring, and whether entire car controller detection door lock unit judgement closes the door success at this time, then entire car controller secondary control again
Vehicle audio provides the prompting of shutdown success or not by sounding horn.
That is the application, which offsets by way of making a sound in door closing procedure or covers vehicle itself, closes the door
Sound improve user experience to improve the sound quality of shutdown, the different of sending can be automatically adjusted according to actual needs
Shutdown sound is offset or covered to acoustic signals；And detect whether car door closes success after shutdown, and provide success or not
Prompting, prevent risk caused by failed closed door.
As Fig. 2 includes the following steps: for the control method for the voice control system that automobile is closed the door
Step 1: acquisition vehicle-state, confirmation car door are in shutdown state；
Step 2: judging whether car door reaches shutdown critical localisation using door position signal；
Step 3: when car door is in shutdown state and reaches shutdown critical localisation, that is to say, that car door is in quilt at this time
During closing and position reaches critical localisation, and car door will inherently issue collision at this time, just needs main control module at this time
The corresponding sounding horn of control car door makes a sound signal, to offset or cover car door itself the sound collided.
As shown in figure 3, all around the loudspeaker of two car doors can be set at B column, due in car door collision process
Exactly comprising colliding between B column, therefore setting is best able to imitate actual sound reproduction position here.Equally, left and right rear door is arranged
At corresponding C column.
As shown in figure 4, the entire motion process of closing of the door moment, we determine car door speed of the car door in critical state
For V0, so-called critical localisation is exactly the position that car door can be collided with vehicle body (such as B column) just, at this location backward, vehicle
Door generates sound due to colliding with vehicle body.Critical localisation as long as speed be less than V0 when car door as long as can not close.We are with critical
On the basis of state, car door is tested out in advance from critical state position to the successfully required time of closing the door, it is assumed that time t0, then
When the speed for reaching critical localisation in car door motion process is greater than V0, car door is from critical state to the successfully required time of closing the door
Respectively less than t0, with the time that the t0 time defined above is that subsequent Music centre loudspeaker works, this makes it possible to entire in car door for we
The sound that can all have loudspeaker to issue in collision process is covered or is offset.General t0 all very littles, if can also without test
To select this empirical value of 2s or 1s.
It is the location information to detect car door that we, which increase the effect close to switch, close to switch, on the inside of car door, after being
The work of continuous sound equipment control loudspeaker provides signal and supports.We, which define to work as, under original state moves to critical potential in car door at closing time
When setting, close to switch output signal, signal is passed to the control unit or entire car controller of sound equipment, sound equipment control unit
It receiving close to after the signal of switch, sound equipment control unit controls Music centre loudspeaker and generates sound, and the duration of sound is t0,
Equally we are in a variety of shutdown audios of sound equipment control unit internal reservoir or a variety of information of acoustic wave, so that Music centre loudspeaker issues
Sound be best shutdown sound quality sound or make the sound closed the door capped.
When opening door of vehicle, car door will also pass through critical localisation, can also detect by critical localisation close to switch
Signal, to prevent sound equipment from can generate sound in car door opening, we increase by an angular transducer in car door and body side, and
It is defined in entire car controller, the car door opening stage, the angle signal that angular transducer detects is negative angle signal, and car door closes
The signal of angular transducer, which is positive signal, when closed state and positive signal is has and arrives small angle signal greatly, the signal of angular transducer
Entire car controller is inputed to, thus judges that car door is to carry out section shutdown then in conjunction with the close position signal switched in shutdown state to be
It is no to reach critical localisation, if so, control vehicle audio driving loudspeaker carry out sounding according to preset audio.Preset audio or sound
Wave signal is by being stored in advance in controller, and since the sounding sound wave of the application is adjustable, can change, better adaptability, exploration is more
It is good, various is adapted to, the automatically controlled level of vehicle is improved, improves NVH quality.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
