摘要： A method and a system to control an auxiliary brake system in a vehicle 100 having a service brake system 150 and an auxiliary brake system 160. Also a system for prevention of wheel lock when braking, which may deactivate a braking action provided by the auxiliary brake system 160 and may actively control a braking action provided by the service brake system 150. The system determines whether the vehicle 100 is in a driving mode for which it is acceptable in terms of safety and/or drivability to block the deactivation of the braking action for the auxiliary brake system 160. If a first manual control 170, which is set up solely for activating braking action for the auxiliary brake system 160, is activated, this means it is acceptable, from a safety and/or drivability point of view, for the driving mode in question, to block the deactivation. Also arranging block deactivation for the auxiliary brake system 160 if it is acceptable in terms of safety and drivability to block it.

摘要： A rotational speed control device maintains a shaft rotation speed. The device includes a housing containing a viscous fluid and a shaft disposed in the housing and rotatable relative to the housing. A rotor is coupled with the shaft for rotation in the viscous fluid. In one arrangement, the rotor is axially displaceable along the shaft between a low-shear position and a high-shear position. A spring mechanism is disposed in the housing and biases the rotor toward the low-shear position. In another arrangement, the rotor may be designed to cooperate with the housing or other nonrotating features within the housing to vary a shear gap according to radially expanding components of the rotor. The rotor, housing and spring mechanism can be designed to cooperate to create large changes in braking torque in response to small changes in shaft rotational speed. This allows the rotation speed to be controlled within a relatively narrow range.

摘要： A hydrodynamic retarder device for installation in a driveline to a vehicle, wherein the retarder device comprises: a blade-equipped stator which, together with a blade-equipped rotor, forms a blade system with a workspace for receipt of an aqueous working medium, and a retarder circuit connected to the workspace to control the inflow of a working medium to the workspace, wherein the retarder circuit is installed to be connected to the vehicle's ordinary cooling water circuit. The retarder circuit comprises valve elements to shut off the flow of working medium to the workspace, and a negative pressure generator is connected in the retarder circuit, which is installed to reduce the pressure in the workspace to or below the vapor pressure for the working medium, so that the workspace is thus evacuated of the liquid working medium. The invention also pertains to a method and a vehicle.
