Described are a method and a device for activating an electric vacuum pump for a brake booster of a vehicle. The brake booster is supplied with a vacuum from a vacuum reservoir. The vacuum pump is designed to increase the vacuum in the vacuum reservoir as soon as the vacuum drops below a predefinable switch-on threshold. In order to avoid unnecessarily frequent switching on of the vacuum pump, which may irritate the driver, an expected decrease of the vacuum in the vacuum reservoir as a result of an instantaneous braking operation is estimated and the switch-on threshold of the vacuum pump is temporarily reduced if the vacuum instantaneously prevailing in the vacuum reservoir minus the estimated vacuum decrease is greater than a predetermined adjustment point vacuum, below which the brake booster can no longer act in a sufficiently boosting manner.
