Patent ID: 7281770

Claim:
A method for braking within a vehicle having a first pair of wheels and a second pair of wheels, a regenerative braking system which selectively provides a braking force to said first pair of wheels and an antiskid braking system which selectively provides a friction braking force to said first and second pair of wheels, said method comprising the steps of: providing an auxiliary bus; selectively and directly coupling said regenerative braking system and said antiskid braking system together by use of said auxiliary bus and an encoded CAN bus, wherein said auxiliary bus is only communicatively disposed between said regenerative braking system and said antiskid braking system and is effective to communicate only unencoded signals between said regenerative braking system and said antiskid braking system; detecting an antiskid braking event; determining whether said antiskid braking event is occurring at either of said first pair of wheels; and transmitting an unencoded signal through said auxiliary bus and said encoded CAN bus to selectively disable said regenerative braking system if said antiskid braking event is occurring only at either of said first pair of wheels such that transmitting said signal through both said encoded CAN bus and said auxiliary bus provides reliability to ensure disablement of said regenerative braking function if one of said encoded CAN bus and said auxiliary bus fails.
