Vehicle brake control with torque imbalance compensation

摘要

The left and right rear brake systems of a vehicle each are controlled by a respective electric torque motor. A rear wheel braking system controls the current to each of the torque motors so that each rear wheel is controlled to a speed having a predetermined relationship to the corresponding front wheel. The relationship between the motor currents when each wheel speed has been established at the predetermined relationship is used to determine a bias current value used to equalize the gains of the left and right rear brake systems.
