Control device and method for controlling a hydraulic auxiliary brake arrangement
A control device (100) and a method for controlling a hydraulic auxiliary brake arrangement (8, 9) of a vehicle powertrain (2) are provided. The hydraulic auxiliary brake arrangement (8, 9) comprises a rotatable first shaft (20) connectable to a second shaft (24) of the vehicle powertrain onto which...

| description | A control device (100) and a method for controlling a hydraulic auxiliary brake arrangement (8, 9) of a vehicle powertrain (2) are provided. The hydraulic auxiliary brake arrangement (8, 9) comprises a rotatable first shaft (20) connectable to a second shaft (24) of the vehicle powertrain onto which a braking torque is to be exerted by the hydraulic auxiliary brake arrangement. The hydraulic auxiliary brake arrangement further comprises a rotor (30), connected to the first shaft, and a stator (32). The rotor (30) and the stator (32) jointly form a toroidal volume (33). The hydraulic brake arrangement further comprises a hydraulic circuit (40) connected to the toroidal volume (33), a reservoir (36) for hydraulic fluid, a pump (34) configured to transfer hydraulic fluid from the reservoir to the hydraulic circuit, as well as a control valve (50) configured to control the hydraulic pressure in the hydraulic circuit. In accordance with the method, the pump is activated based on a predicted future driverinitiated demand for brake torque and the control valve is controlled so that a hydraulic pressure in the hydraulic circuit is lower than a preselected threshold value. A computer program, a computerreadable medium and a vehicle (1) are also disclosed. |
