Abstract: A method for mitigating dynamic traction events in a vehicle includes detecting a wheel speed increase indicative of a wheel slip event, determining a frequency of a rate of change of the wheel speed during the wheel slip event, comparing the frequency to a threshold, and changing a traction control parameter when the frequency satisfies the threshold. In at least some implementations, the traction control parameter is a setting of a traction control system relating to one or both of throttle reduction and braking.

Abstract: A method for controlling an electro-hydraulic brake system includes the steps of determining an expected pressure of the brake system, determining the actual pressure of the brake system, and comparing the actual pressure to the expected pressure. If the actual pressure is less than the expected pressure by more than a threshold, a brake booster is isolated from a first brake assembly. A subsequent actual pressure is determined and compared to the expected pressure. If the subsequent actual pressure is less than the expected pressure by more than a threshold, a brake booster is isolated from a second brake assembly. A second subsequent actual pressure is determined and compared to the expected pressure. If the second subsequent actual pressure is less than the expected pressure by more than a threshold, a brake booster is isolated from both the first brake assembly and the second brake assembly.
