A method of operating a vehicle having a friction braking system and a regenerative braking system is presented here. The method determines a regenerative torque capacity, calculates a desired regenerative torque amount for the braking system, detects that the desired regenerative torque amount exceeds the regenerative torque capacity by at least a threshold amount, and controls actuation of the friction braking system in response to the detecting. Another operating method determines a coastdown torque capability of the vehicle, calculates a desired coastdown torque amount, detects that the desired coastdown torque amount exceeds the coastdown torque capability by at least a threshold amount, and controls actuation of the friction braking system in response to the detecting.

A method for adjusting braking in a vehicle having wheels and a regenerative braking system is provided. The method comprises the steps of providing regenerative braking torque for the vehicle via the regenerative braking system at a first level if a wheel slip of the vehicle is not present, and providing regenerative braking torque for the vehicle via the regenerative braking system at one of a plurality of modulated levels if the wheel slip is present. Each of the plurality of modulated levels is dependent on a magnitude, a location, or both, of the wheel slip. Each of the modulated levels is less than the first level.

A vehicle brake system and method designed to maximize the contributions from a regenerative braking system, yet still provide adequate safety measures that address potential regenerative braking failure. According to one embodiment, the method determines both a requested deceleration from the driver and an actual deceleration experienced by the vehicle, and uses the difference between these two values to calculate a deceleration error that can be integrated over time and compared to an error threshold. If the integrated or accumulated deceleration error surpasses the error threshold, then the method may reduce or disable the regenerative braking system until it can confirm that it is operating properly.
