摘要： A cooling system for a vehicle propelled by an electric machine. The cooling system is arranged, when the vehicle is operated in a braking mode, to control a first and a second radiator valve to direct a flow of fluid from a radiator through a first fluid circuit and prevent the flow of fluid from the radiator to enter the second fluid circuit, control a compressor arrangement to flow a refrigerant in a direction from a heat exchanger to a condenser of a third fluid conduit, and control a second circuit valve arrangement to direct a heat source fluid to circulate through a heat exchanger and an electric heat source.

摘要： A braking system for a vehicle at least partially propelled by an electric traction motor electrically connected to an electric power system. The braking system comprises an electric machine configured to be electrically connected to the electric power system, the electric machine comprising a first output shaft and a second output shaft, an air blower controllably connected to the first output shaft by a clutch, the clutch being controllable between an open position in which no power is transmitted from the electric machine to the air blower, and a closed position in which power is transmitted from the electric machine to the air blower, and a fluid pump operatively connected to the electric machine via the second output shaft, wherein the fluid pump is arranged in upstream fluid communication with a fluidly operated member and in downstream fluid communication with a fluid tank.
