Abstract
A control device operates a vehicle hydraulic brake system (a) in a fallback mode during which a simulator isolating valve is closed and a brake circuit isolating valve is open, (b) in a simulator mode during which the simulator isolating valve is open and the brake circuit isolating valve is closed, and (c) to transition from the fallback mode to the simulator mode using an intermediate mode in which, at least once, the simulator isolating valve and the at least one brake circuit isolating valve are simultaneously closed for a first time interval, the simulator isolating valve and the at least one brake circuit isolating valve are simultaneously open for a second time interval, and the simulator isolating valve is closed for a third time interval, while the at least one brake circuit isolating valve is open at least part of the time during the third time interval.
