1. A method comprising:
monitoring a manually applied braking value based on a displacement of a brake pedal mechanically coupled to brake calipers;
determining that an additional braking value is needed to provide a needed total braking value;
in response to determining that the additional braking value is needed, applying a controller braking value as the additional braking value by actuating an actuator to physically move the brake pedal away from a foot of a driver;
decaying the manually applied braking value while the controller braking value is applied;
detecting, using vehicle sensors coupled to a controller, that application of the needed braking value results in an updated vehicle trajectory that satisfies predetermined braking threshold criteria; and
after detecting that the updated vehicle trajectory satisfies the predetermined braking threshold criteria, incrementally decreasing the controller braking value and incrementally increasing the manually applied braking value such that the brake pedal incrementally returns to the driver's foot.
