The specific embodiment
Embodiments of the invention are described with reference to the accompanying drawings.In the following description, many details have been set forth in order to the person of ordinary skill in the field is more fully understood and realize the present invention.But, the person of ordinary skill in the field is apparent that realization of the present invention can not have some in these details.In addition, should be understood that the specific embodiment that the present invention is not limited to introduce.On the contrary, can consider to implement the present invention with the combination in any of feature described below and key element, and no matter whether they relate to different embodiment.Therefore, following aspect, feature, embodiment and advantage usefulness for illustrative purposes only, and should not regard key element or the restriction of claim as, unless clearly propose in the claims.
Referring now to Fig. 1, at step S100 place, auto meter can be by such as CAN(Controller Area Network, controller local area network) bus obtains the real-time vehicle data from vehicle-mounted sensor or pick up camera.
Above-mentioned one or more sensors or pick up camera etc., obtain the real-time vehicle data of relevant running state of the vehicle by sensing, the for example outer temperature of the speed of a motor vehicle, engine speed, engine condition, oil consumption, Fuel Oil Remaining, tire pressure, leading vehicle distance, water tank temperature, oil circuit flow detection, brake disc situation, brake facing situation, current restriction speed per hour, car light situation, car, level situation, ABS(Anti-lock Braking System, anti-skid brake system) situation, ESP(Electronic Stability Program, electric stabilizing system) situation etc.And obtain the real-time vehicle data of above-mentioned running state of the vehicle when auto meter after, just can carry out follow-up data analysis accordingly, to determine whether need to User Alarms, to point out the unusual of corresponding vehicle situation.
At step S102 place, auto meter is judged corresponding warning message according to the vehicle data that obtains.
Warning message comprises following three types: the mistake that needs sudden stop to handle, the alarm that can handle after a while, and general information indicating.
The mistake that needs sudden stop to handle comprises that engine abnormity, leading vehicle distance are too near, oil circuit Traffic Anomaly, brake disc are malfunctioning etc. needs emergency treatment, not so can cause the situation of life and property damage.
The alarm that can handle after a while comprise oil mass very little, the garage's maintenance maintenances that can continue to travel such as tire pressure is low excessively, brake facing is too thin, antilock system failure, ESP is malfunctioning, car light is bad, storage battery is aging, not so can worsen the situation that causes serious consequence.
General information indicating comprises current restriction speed per hour prompting, car outer temperature prompting, crashproof prompting, changes the information of help driver safety driving such as prompting.
At step S104 place, auto meter can convert warning message to speech data, reports in vehicle-mounted loudspeaker, and vehicle-mounted loudspeaker for example can be auto audio equipment.
In addition, auto meter can also be converted to warning message animation, image or text data, shows in Vehicular display device, and Vehicular display device for example can be the read-out on the auto meter.Based on the auto meter with different display panel type, the display format of different modes can be provided, for example for the auto meter with segment encode screen, can show the warning message of textual form or the warning message of simple image form, and for having the TFT(TFT) auto meter of liquid crystal display, then can show the warning message of various ways such as animation, image, literal.
Alternatively, auto meter can also select needs to show and/or the warning of reporting and the warning of cancelling not needs demonstration and/or reporting according to user preference.For example, the user is for fear of the interference of some warning message or think that some warning message is unnecessary, can cancel demonstration and the report of some warning message, and perhaps the user is for fear of taking sb's mind off sth, only can select to report and warning not, etc.The user for example can by long by or the operation selecting or cancel of the short mode that touches the button, this button can be the OK key that has multi-functional bar in being arranged on the control guidance panel, also can be the OK key on the multifunctional direction dish, perhaps the button portion on the auto meter or the options button on the touch-screen.
When dissimilar a plurality of warning messages take place simultaneously, by control Vehicular display device and/or vehicle-mounted loudspeaker, can preferentially show and/or report mistake, be alarm then, be information indicating again.
Different warning messages to same type also can preestablish different priority, when a plurality of warning messages of same type take place simultaneously, by control telltale and/or loud speaker, can according to priority show in proper order and/or report.
For example, belong to wrong warning message by priority can be arranged in order malfunctioning into brake disc, leading vehicle distance is too near, engine abnormity, oil circuit Traffic Anomaly etc.
For example, the warning message that belongs to alarm can be arranged in order to brake facing is too thin, antilock system failure, ESP is malfunctioning, car light is bad, tire pressure is low excessively, storage battery aging, oil mass waits very little by priority.
For example, the warning message that belongs to information indicating by priority can be arranged in order to crashproof prompting, change that prompting, current restriction speed per hour are reminded, the outer temperature prompting of car etc.
In addition, auto meter also can be according to the motoring condition of vehicle, and demonstration and/or the report mode of warning message arranged.
For example, when vehicle was in halted state, for example during vehicle ignition, Vehicular display device showed and/or vehicle-mounted loudspeaker is reported wrong, alarm and information indicating, and repeating to show and/or report wrong, alarm and information indicating at interval with the very first time, this time gap can be 5 seconds or 10 seconds etc.This repeat to show and/or report help to strengthen the user and remember important information, and avoided because the user is leaked and seen or leak the hidden danger of listening important information to cause.
For example, when vehicle is in the low speed driving state, be lower than 80km/h as speed of operation, Vehicular display device shows and/or vehicle-mounted loudspeaker is reported mistake, alarm and information indicating, and repeat to show and/or report mistake and alarm with second time gap, this time gap can be 20 seconds or 30 seconds etc., wherein second interval greater than the very first time at interval, this be for fear of warning message repeat too frequently to show and/or report in the driving process of vehicle can the dispersion chaufeur attention.
For example, when vehicle is in high-speed travel state, be higher than 80km/h as speed of operation, Vehicular display device only shows and/or vehicle-mounted loudspeaker is only reported mistake and alarm, this is for fear of the demonstration of too much unessential relatively warning message and/or reports the attention that can disperse chaufeur in the process of running at high speed of vehicle, and repeat to show and/or report mistake with the 3rd time gap, this time gap can be 1 minute or 2 minutes etc., wherein the 3rd interval greater than second time gap, and this is to repeat to show and/or report the attention that can disperse chaufeur in the process of running at high speed of vehicle too frequently for fear of warning message.
Fig. 2 illustrates the schematic work block diagram that the car alarming method of using further embodiment of the present invention is carried out the warning of car alarming.As shown in Figure 2, described warning comprises: a plurality of onboard sensor 1-n, auto meter, true man's sound bank 202, auto audio equipment 203.Wherein, auto meter comprises controller (ECU) 201 and auto meter LCDs 204 at least.Link to each other by the CAN bus between controller 201 and onboard sensor.Controller 201 is by CAN bus read sensor 1, sensor 2 ..., sensor n(n is the integer greater than 1) signal, thereby judge corresponding warning message, controller 201 is according to warning message and current language setting (for example English, Japanese, French, German, mandarin etc.), from true man's sound bank 202 of prerecording, read corresponding voice document, in auto audio equipment 203, report warning message.Those skilled in the art will appreciate that true man's sound bank 202 also can replace with synthesis speech database.But, this true man's voice of prerecording with compare based on the synthetic speech of coding, sound clarity nature, the resolution height is conducive to express more accurately warning message, thereby more effectively plays the effect of caution.And, warning on auto meter read-out 204.
Though more than described exemplary embodiment of the present invention, the present invention is not limited thereto.The person of ordinary skill in the field can make various changes and modification, and does not break away from the spirit and scope of the present invention.Scope of the present invention only is defined by the claims.
