All-wheel drive torque vectoring by electronic brake system control

摘要

A control system to generate a yaw torque of an all-wheel drive vehicle comprises a brake control module 18. The brake control module 18 determines the desired powertrain torque 44 for the vehicle 10 based upon a plurality of factors including available torque from the powertrain. The brake control module 18 determines a first torque 44 and a second torque 26, wherein the first torque 44 and the second torque 26 are combined to provide the total desired yaw torque 49 of the vehicle 10. The first torque 44 is generated between wheels of the vehicle 10 by applying torque 44 from the powertrain 14 to different wheels 21 of the vehicle 10 and the second torque 26 is generated by applying different braking torque from a braking system 16 of the vehicle 10.
