Idea details
Horch
Horch has many possible modes, however the main/important ones are as follows:-

1) Help Mode: Horch works rather like Shazam, it listens to “strange” car sounds and compares them with a database of typical fault sounds for each car model, e.g. the ticking sound of a worn transmission CV Joint, or high or low frequency “clonk” from worn small/big end bearings in the engine. In this mode the customer no longer has to say to the service dept “my car’s not working properly, it’s making a strange new sound…..”. As more sounds are capture, verified and added to the database, the App becomes more accurate at diagnosing faults automatically. Pictures and video can also be captured and uploaded to assist the diagnosis. Once diagnosed this information can be sent to the local service agent to help them prepare a rapid repair.
2) Pro-mode: As above, but aimed less at private car users, rather at the second hand car dealer market, or any used car private purchaser: In this mode, the dealer inspecting a prospective purchase captures sounds from around the car following a specific work flow. These sounds are then cross-correlated with the database and a report is generated which identifies possible car defects.
3) Fun: Horch plays a random car (engine) sound and then asks the user to guess which car the sound belongs to.

Why is the App called Horch? Horch is the imperative form of the German verb hören, to hear i.e. “LISTEN”.

Good idea X-by-light!! I really like fun mode :) User2830
Please don't check all my typos - one might question my Englishness. User3194
Yes thats true, as you said, this app is more for a smartphone than in an in-car-app! By the way, sorry for my typos! I like the contribution! User2815
Yes Sorry, I assumed folks here would know something of the VW group history. Horch is of course an historical car brand that gave birth to the Audi name (latin for listen). User3194
The interference isn't a big issue for state of the art digital signal processing techniques. In fact you are capable of differentiating a specific sound from high levels of background noise. I bet if you were in a very load city market place you could tell if someone started to play violin. It has a characteristic audio signature and if you know it you "focus" in on it filtering out all the other background noise. A skilled mechanic can easily recognise the signature sound of typical faults, even if you as a non-specialist do not recognise the sound. I think it would be too expensive for the car manufacturers to install microphones and cameras all around the vehicle to cover every possible fault location. Thus a movable device (any smart phone) allow us non-specialists to give a more intelligent fault description to our friendly VDub service technician. User3194
I think the problem is that you have many intereference sounds within the car, plus the Car System itself should detect errors instead of an app. Even though i this idea would be useful in older cars where it is more likely that problems occur. You could use some frequence analyser and A.I. to even assume and guess where the sounds could be from. Whether it is proportional to the number of revolutions, the velocity or the turn signal.

Good idea. And don't forget to mention the logo is some historic car brand. User2853
Very goog idea! I know there is a company which has recorded engine sounds of many cars with different kilometer reading, and stored them in a database. This company is able to detect the de facto kilometer reading of cars with the help of these sound. So I'm sure your app idea could work properly! User2858

Hi X-by-light ... sorry the time was to short to implement some idea of you as an app! Today I uploaded my last app. It is not perfect but I hope you like it anyhow! Thanks for your comments it was a nice time with you at the contest! User2858
Hi my frnd, Thx for ur support & valuable comments. Wish u all the success & good luck. User3148
Hello, thanks for the comment and the link to recaro web site. I really don´t know a existence of a simmilar product like my idea....but i´m glade to have the same idea....:) User2852
I will have a look at your ideas but I am afraind that the time is to short now because there are just three days left :-( User2858
Thanks for your comments!! it was intense, several sleepless nights in between work and watching football lol. User3237
Hi Lars, I've added a few new ideas, any chance of throwing your coding skills at some of them? If I tried myself, I think we would all get a "blue screen" experience :-) User3194
Hi X-by-light! Thank you very much for your detailed comments on my apps! - SpeedLimit: you are absolutely right that actual navigation system are able to show me the speed I am allowed to drive but this was my very first app in flash and I just arrived at home from a trip to Prague and my "old" navigation system didn't have this feature ;-( so that idea came up. - AffectiveMusicPlayer: I implemented a protoype of such a system in my master thesis which has an accuracy of over 90 percent for music genre classification and over 80 percent for emotion classification, but this app just uses "pre-tagged" songs to generate the playlist. My plan for the automode is similar to your suggestion. I hope I will find time to finish it, because I was waiting for the new driving profiles a long time and now I am very busy :-( - FuelStations: max-e made a nice fuel gauge app. (http://www.app-my-ride.com/flash-app/load-in-player/appId/59) Do you mean something like that? I think you don't want to know how much the government is subsidising in fuel tax for each litre or do you want to get very angry at every tank stop :-) Perhaps I should combine my FuelStation app with my AffectiveMusicPlayer app -> if(fuelstop == true) then MusicEmotion = Pleasure ---------------------------- P.S.: No I am not working for Apple :-) User2858
Hi X-by _light, Thx for ur visit & thx for ur valuable comments & suggestions.Thx very much my frnd User3148
Hi X-by-light! Thanks for your comment :). Your idea about donor card rocks! I like it and when I finish my exams, I'll implement it. Thanks!! :). Tonight I'll see your latest works ;) User2830
Hi max-e Thanks for the clarification. Clearly some ideas are better suited to deployment on the car's OEM equipment, especially where there may be some safety-related aspect. Although there are also advantages to having an off-boardable solution. Access to vehicle data shouldn't be a big technical challenge, or even iPhone dependant (via dock connector). Data could be transfered via Bluetooth (not very stable or secure though), WiFi (better) or when UWB starts appearing on phones that would be the best wireless connectivity. User3194
About the in App System: the idea of this contest is, that you have an iphone like App operating system, just not on the actual iphone, but within your car! You can open the APPs in your VW Golf, where also your navigation system runs. The advantage of this is that you can receive car specific data (e.g. is your car light switched on) that you cannot get with your phone. Do you get the idea? User2815
I just added a selection step! Know you can start my app with one ball ;-) User2858
Hi x-by-light, thx or visitng my profile, expecting ur valuable comments too User3148
Hi X-by-light! Thanks for your comment. I will add a configuration step in my app where you can choose how many balls will appear ;-) User2858
Welcome to the contest x-by-light! Hope you like the platform! Cheers! User2776
For those into gaming consoles you could take the (iPhone) interface and play with vehicle dynamic settings at home then when you find the ones that work the way you like, store and take them to the real car. User3194
My wife asked me if it could emulate a break-down (clutch failure etc)! Well of course you could choose any British classic car for that! But seriously, programming in various system failures could help driving instructors teach people how to react under such conditions, with actually having to break the car. The possibilities are endless. User3194
