Abstract
A brake system for a vehicle includes a parking brake with an air-quantity-boosting-valve device for aerating and deaerating at least one spring brake cylinder of the parking brake, at least one electrically actuatable control valve for controlling the air-quantity-boosting-valve device, an electrical control device electrically coupled to the electrically actuatable control valve for controlling the electrically actuatable control valve, and an electrical actuating device coupled to the control device for actuating the parking brake. In order to be able to resort to available series-produced components, the air-quantity-boosting-valve device, the control valve, the electrical control device and the actuating device are, in each case, embodied as autonomous components arranged spatially separate from one another.
