Hi everyone. Newby here. I am a novice in electronic circuit design but would love to learn.
I want to create a circuit that can take two ABS sensor outputs, compare them and pass through the higher of the two.
Prior to the comparison the signals are being passed through a reluctor interface that changes it from a magnetic to a hall effect output. This adapter is already in place and working.
I need to take these two hall effect signals and send the ECU the higher of the two. The reason for the circuit is a traction control system on my car. The ecu can only receive one driven and one non-driven input. This has the effect, as the non-driven is on only one front wheel - it causes the traction control to behave differently on left versus right hand turns.
Bosch make the perfect device called the Speed Box 2, but at a cost of 770 Euro, they can go jump......
What I need to know is how to compare two different square wave signals, and output the higher. Any advice on the type of circuit or chip that may do it would be GREAT!
Thanks heaps everyone.
Regards,
Jeff
