Patent ID: 8285465

Claim:
A traction control module for a vehicle having a first axle, a second axle, and an engine that produces torque, the traction control module comprising: a first comparator that receives a first-axle, left wheel slip value and a first-axle, right wheel slip value, the first comparator generating a first axle slip value indicative of a greater of the first-axle, left wheel slip value and the first-axle, right wheel slip value; a second comparator that receives a second-axle, left wheel slip value and a second-axle, right wheel slip value, the second comparator generating a second axle slip value indicative of a greater of the second-axle, left wheel slip value and the second-axle, right wheel slip value; a first summing node that receives the first axle slip value and a first axle target slip value and that generates a first slip error; a second summing node that receives the second axle slip value and a second axle target slip value and that generates a second slip error; a first axle controller that generates a first axle torque command output based on the first slip error; and a second axle controller that generates a second axle torque command output based on the second slip error.
