An electric brake booster vacuum pump of a vehicle has a deactivation level determined according to a percentage of maximum available vacuum at the instant altitude of the vehicle. The activation level may be determined in the same way. The invention provides for earlier on-switching of a vacuum pump at altitude, while ensuring that the off-switching value is achievable at low atmospheric pressure.
