1. A method for braking a vehicle, including:
- raising a supply voltage of an on-board vehicle electrical system from a first voltage level to a second voltage level that is less than or equal to a maximum permissible value; and
applying the supply voltage at the second voltage level to;
1) at least one electrically operated actuator of a vehicle brake system in accordance with a braking request made by a vehicle control system when at least one pre-specified condition is met, such that braking torque is built up at one or more vehicle wheels independently of the driver, and2) at, least one other control device of the on-board vehicle electrical system, the at least one other control device including a microprocessor.

Abstract
The invention relates to a method, wherein an electrically operated actuator of a vehicle brake system is controlled in accordance with a braking demand of a vehicle control system, such as occurs in electronic stability control. According to the invention, a supply voltage of the vehicle electrical system applied to the electrically operated actuator is increased if at least one specified condition is met. Thus, the pressure build-up by a hydraulic pump can e.g. be accelerated during emergency braking.
