| 主权项 | 1. A method for conserving vacuum for a vehicle, comprising: limiting a first brake line pressure increase at a wheel brake in response to a first increase in brake pedal force when the vehicle is stopped; limiting a second brake line pressure increase in response to a second increase in brake pedal force when vehicle speed is non-zero and less than a threshold speed; and decreasing vacuum in a brake booster working chamber via a valve while limiting the first brake line pressure increase while an engine of the vehicle is operating. | ||
