In one embodiment, the threshold value speed of a motor vehicle is 10 ~ 30km/h; Threshold value deceleration/decel is 0.5 ~ 2m/s
2; Threshold value corner is 150 ~ 250 °.
In one embodiment, vehicle velocity V, deceleration/decel a, brake signal b pass to BCM module by after the process of ABS/ESP module acquires; Steering wheel angle ω passes to BCM module by after the process of EPS module acquires; Judge whether automobile is in curved state of slowing down continuously by BCM module, if be in when slowing down curved state continuously, loudspeaker are controlled.
In one embodiment, the method also comprises the control enable signal T received from controlling enable switch, when controlling enable signal T and existing, judge whether automobile is in curved state of slowing down continuously by BCM module, if be in when slowing down curved state continuously, loudspeaker are controlled, when controlling enable signal T and not existing, BCM module does not control loudspeaker.
In one embodiment, enable master cock is on the steering wheel integrated or be integrated on console or by human-computer interaction interface and provide.
In one embodiment, controlling the default conditions of enable signal T after automobile powers on is do not exist.
In one embodiment, when controlling enable signal T and existing, indicate the existence of described control enable signal T, the mode such as can lighted by the functional indicator light be positioned in instrument is indicated.
The control method of horn trumpet of the present invention provides the Based Intelligent Control for loudspeaker, when judge automobile be in slowed down curved state continuously time, automatically loudspeaker are operated, can without the need to chaufeur interventional procedure again, therefore, it is possible to promote the traveling comfort and safety driven.
Accompanying drawing explanation
The above and other feature of the present invention, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 discloses the control logic schematic diagram of the control method of the horn trumpet according to one embodiment of the invention.
Fig. 2 discloses the schematic diagram of the control logic of the control method for realizing horn trumpet of the present invention.
Detailed description of the invention
Shown in figure 1 and Fig. 2, the present invention proposes a kind of control method of horn trumpet, judge whether automobile is in curved state of slowing down continuously according to vehicle velocity V, deceleration/decel a, brake signal b and steering wheel angle ω, if automobile is in curved state of slowing down continuously, then continue ring loudspeaker.
Regulation according to security civilization is driven: drive a car in road sharp turn traveling, needs the signal of ring loudspeaker.When automobile was in continuously curved state, following condition should be met: automobile is in motoring condition, therefore should possess certain speed of a motor vehicle.Needing when crossing curved to slow down, therefore should there is certain deceleration/decel.The effect of slowing down mainly is provided by brake, therefore should there is brake signal.Meanwhile, under the curved state of mistake, direction is taken inventory at certain corner.
Based on above-mentioned analysis, whether being in the judgement of crossing curved state continuously for automobile can according to following condition, when meeting simultaneously: when vehicle velocity V is not more than the threshold value speed of a motor vehicle, deceleration/decel a is not less than threshold value deceleration/decel, brake signal b exists, steering wheel angle ω is not less than threshold value corner, judge that automobile is in and cross curved state continuously.In one embodiment, the threshold value speed of a motor vehicle is 10 ~ 30km/h, threshold value deceleration/decel is 0.5 ~ 2m/s
2, threshold value corner is 150 ~ 250 °.
Continue with reference to shown in figure 1 and Fig. 2, in one embodiment, vehicle velocity V, deceleration/decel a, brake signal b are by ABS/ESP module acquires, and steering wheel angle ω, by EPS module acquires, judges whether automobile is in the curved state and being performed by BCM module the control of loudspeaker of slowing down continuously.In one embodiment, the method also comprises the control enable signal T received from controlling enable switch, when controlling enable signal T and existing, performed by BCM module and judge whether automobile is in slowed down continuously curved state and the control to loudspeaker, when controlling enable signal T and not existing, BCM module does not control loudspeaker.The object arranging enable signal T makes chaufeur to start loudspeaker Based Intelligent Control according to the needs of oneself or to close the Based Intelligent Control of loudspeaker.As shown in Figure 2, the judgement signal of this control enable signal T and aforesaid vehicle velocity V, deceleration/decel a, brake signal b and steering wheel angle ω, jointly as basis for estimation, forms a discriminant function f (V, a, b, ω, T).Need to meet above-mentioned condition simultaneously, just can start the Based Intelligent Control of loudspeaker.Simultaneously, continue with reference to shown in figure 1 and Fig. 2, loudspeaker are still subject to the control from the routine operation signal C on bearing circle.Routine operation signal C is also provided to BCM, exports final loudspeaker control signal F to control loudspeaker by BCM.Shown in figure 2, at above-mentioned discriminant function f (V, a, b, ω, T) and routine operation signal C between be or, the i.e. relation of " or ", that is, no matter be discriminant function f (V, a, b, ω, T) or routine operation signal C, can both control loudspeaker independently.
In one embodiment, controlling enable signal T is provided by enable master cock, and enable master cock is on the steering wheel integrated or be integrated on console or by human-computer interaction interface and provide.Controlling the default conditions of enable signal T after automobile powers on is do not exist, and is namely in closed condition, just can there is this control enable signal after needing chaufeur manually to open.In one embodiment, when controlling enable signal T and existing, the existence of described control enable signal T is indicated.Such as, the mode that can be lit by the functional indicator light be positioned in instrument indicates the existence controlling enable signal T.
Summed up, when meeting following condition simultaneously: when vehicle velocity V is not more than the threshold value speed of a motor vehicle, deceleration/decel a is not less than threshold value deceleration/decel, brake signal b exists, steering wheel angle ω is not less than threshold value corner, control enable signal T exists, judge that automobile is in curved state of slowing down continuously, control loudspeaker by BCM and continue ring.When above-mentioned condition meets no longer simultaneously, BCM can control loudspeaker and close.
The control method of horn trumpet of the present invention provides the Based Intelligent Control for loudspeaker, when judge automobile be in slowed down curved state continuously time, automatically loudspeaker are operated, without the need to chaufeur interventional procedure again, therefore, it is possible to promote drive traveling comfort and safety.
Above-described embodiment is available to be familiar with person in the art to realize or to use of the present invention; those skilled in the art can be without departing from the present invention in the case of the inventive idea; various modifications or change are made to above-described embodiment; thus protection scope of the present invention not limit by above-described embodiment, and should be the maximum range meeting the inventive features that claims are mentioned.
