The present document relates to a driveline for a vehicle, the driveline comprising a hydrodynamic retarder, a first driveline component such as a transmission input, and a controller configured to activate the hydrodynamic retarder at a point in time which is determined based on a rotational acceleration of the first driveline component. The present document further relates to a method of controlling a hydrodynamic retarder.

A vehicle control device for controlling a vehicle with a drive source, a friction transmission mechanism provided between the drive source and drive wheels and a fluid transmission mechanism provided between the friction transmission mechanism and the drive source includes a suppression unit configured to suppress a decrease of a speed ratio of the fluid transmission mechanism if the speed ratio becomes negative when the vehicle starts.

A thermostatic bypass valve functions to regulate fluid temperature and also to act as a pressure relief valve using a single valve bore. The poppet valve includes a cylinder with a chamber that is thermally immersed in a source passageway such that the valve state is determined by the temperature of the fluid flowing through the source passageway as opposed to the fluid flowing through a return passageway. When the fluid in the source passageway is hot, a poppet is forced against the return passageway side of a valve seat. The poppet may either be rigidly attached to the cylinder or may slide with respect to the cylinder and be forced against the valve seat by a spring. A piston may either be rigidly attached to the housing or may be forced toward the valve seat by a spring.

A drag torque reduction device for an automatic transmission includes a hydraulic controller with a diversion for excess cooling oil into an oil sump that is positioned upstream of a radiator relative to a flow of fluid to the radiator. The diversion includes a temperature-dependent, switchable aperture and a switching valve. The temperature-dependent, switchable aperture is configured to close above a temperature threshold. The switching valve is configured to close above a threshold pressure.
