car security system by a mobile

Hi,

I am electronic engineer. I need some technical help to connect between car alaram system and a private mobile to monitor a car status from any palce in the world and control the function of car acion according to that.


Regards

Sabri Fathi

Any idea how you are going to go about this?

Sounds like to need a diagnostic device that can access the vehicle bus and some sort of transmitting device to get it to your phone.

Vehicle bus systems are extremely complicated. Getting the information that you want from the bus will be in itself a very difficult project. You can buy diagnostic tools, but I don't think that they will provide the information that you want. They usually just provide error codes which need to be looked up in the CAN protocol standard, such as ISO 15765 or SAE J1939.

hi my friend

Thanks for your interest.I hope know that i have a good cooperation with a big company in Hong Kong for car alarm system .We have make some success. I am agree with you that this is not easy project. but if you thing if we succeede to find good cooperation with mobile communication companies, i think this will be so good.

There are more and more functions has been defined on SAE-J1939, extermely for emission control. And it is hard to get the staff fully tested with a real car, so our company developed our own SAE-J1939 simulator, and now it is available to the public.

Six editions of Au SAE-J1939 simulator are released:
Engine Basic Edition (H)
Engine Premium Edition (Li)
Vehicle Platinum Edition (Na)
Engine Basic Plus Edition (K)
Engine Premium Plus Edition (Rb)
Vehicle Platinum Plus Edition (Cs)

So will it make my mileage and power better or not?

This one will definitely improve the fuel economy and power. It has been used on a VW Vanagan with Subaru 2008 CAN buses Engine. The Same Subaru Engine can also be used for airplanes and older Subaru vehicles.

Au Group Electronics is also pleased to announce successfully developed an ABS ECU CAN Simulator with Speed input. This device can be used to measure the vehicle wheel speed from the hall sensor and broadcast the speed information in a vehicle (e.g. Subaru) high speed CAN (Controller Area Network). The vehicle CAN speed information (generated by this device) is critical for any modern engine ECU (e.g. Subaru 2.5L, 3.3L engines) emission control strategy and full performance.

I have an aftermarket programmer already that does all that stuff too. Still dont do jack for mileage. Claims its doing it but I never saw a confirm able improvement.
The guys I know also have different programmers from different manufactures and non of them claim any greater mileage gains either.
1999 Ford F250 Super Duty 4WD with Triton V10
Any suggestions other than swap out the engine with my old Big block V8?
Or do a major engine rework?

Our ABS ECU CAN simulator only feed speed info to Subaru Engine ECU through CAN bus communication, this will prevent the Engine from entering limp-home mode. So user can keep the good performance on Subaru engines (many new CAN-bused Subaru engines has been used for VW Vanagan, airplanes, old Subaru Vehicles, etc). Compare with Limp-home mode, keep the engine in normal mode will improve fuel economy, power and the idle is much smoother.

Most of the people doing that for power purpose. There may be a few for fuel economy now due to higher gas price.

Race fans also like to use the newer Subaru engines to boost the power and acceleration performance of the vehicle. The Subaru boxer seems a good fit on VW Vanagan vans.

Ive heard good things about Subaru too! But it doesn't help me out much. All american made vehicles in my family.

Actually there are some good USA made engines too. E.g. GM NorthStar family for Buicks.
Chevy Covert gets a powerful engine too.

Didn't both of those lines get the ax recently? Reliable and efficient was not cost effective for GM to produce.

Still rather impressive stuff you have here! I dont understand most of its purpose but still its impressive.

The J1939 simulator is designed to simulate Engine, ABS, Transmission CAN signal (e.g. Engine RPM, Oil pressure, Vehicle speed, etc). It can be used for incoming inspection (e.g. Instrument panels), odometer durability test, new product development, etc. So no diesel engine need be running for incoming inspection or odometer validation tests.

The ABS ECU CAN simulator is designed to run together with Subaru Engines (05 and later models equipped with CAN bus technology). It will keep the engine running at normal mode for best fuel economy and power.

I believe Buick and Chevy will survive. Fords seem running better with its new well designed products. The 3rd one will probably be gone forever. Dodge uses lots of Cummins diesel for its pick-ups. The industry slow-down makes Cummins laid off many workers too.
