Automotive Traction Control

Hi all,

Currently I am designing a Traction Control System for my car. The system has to periodically cut the ignition of the engine in order to reduce engine power when the driven wheels are slipping. Therefore I am looking for a way to do this. It must be a fail safe design, thus when power off, the ignition signal must be routed through.
Does anyone have some experience in this? Help would be very much appreciated.

Thank you and best regards:

Alex

Maybe some additional information is required:

The primairy side of the ignition coil is on one side connected to the 12V power supply. When the Engine Control Unit(ECU) decides to make the spark plug spark, it connects the other side of the primairy side to ground.

The Traction Control System has to prevent the ECU from grounding the coil, by disconnection the ECU from the coil. There can be quite high voltages on the primairy side of the coil (like 400V) and the high current peaks(like 5A). This makes it difficult to find the right way to disconnect the ECU from the ignition coil.

I hope someone has some suggestions to get this thread started

Best regards

Alex
