Problems solved by technology
While water braking may work well with some types of engines, it may not work well with other types of engines that have low thermal inertia (especially if the cooling circuit does not include the motor) (in which case the water braking can significantly heat the cooling system), which can be challenging
For example, in the case of a fuel cell vehicle, the temperature of the water will be heated well above the recommended fuel cell temperature limit of 80°C, and therefore cannot be used to cool the fuel cell

Embodiment Construction
[0072] figure 1 Shown is a combined cooling and water braking system comprising at least one exemplary embodiment of the present invention ( figure 1 Not shown in the vehicle 1. Although the vehicle 1 is shown in the form of a truck, other types of vehicles may be provided according to the invention, such as buses, construction equipment or passenger cars.
[0073] The truck (vehicle 1 ) comprises a cab 2 in which the driver can operate the vehicle 1 . The vehicle 1 comprises a plurality of road wheels 4, here shown as two pairs of wheels, however in other embodiments there may be a different number of wheels, such as three, four or more pairs of wheels. Vehicles can have propulsion ( figure 1 not shown), the propulsion device is configured to generate propulsion power for the vehicle. The propulsion means may be, for example, an internal combustion engine, a battery powered electric motor, or a fuel cell powered motor.
[0074] will target figure 2 The schematic illust...

There are provided a combined cooling and water braking system for a vehicle, and a method for cooling a propulsion device of a vehicle and water braking a pair of wheels of a vehicle. The system comprises a first water recirculation loop having a first heat exchanger configured to cool water flowing in the first water recirculation loop, the first water recirculation loop comprising a water conduit for transporting heat away from a propulsion device configured to generate a propulsion power for the vehicle. A second water recirculation loop having a second heat exchanger is configured to cool water flowing in the second water recirculation loop. A retarder is configured to be coupled to a pair of wheels of the vehicle. The second water recirculation loop may be selectively used for cooling the propulsion device and for providing water to the retarder for water braking.
Description
technical field [0001] The invention relates to a combined cooling and water braking system for a vehicle. The invention also relates to a vehicle comprising such a system. The invention further relates to a method for cooling a propulsion device of a vehicle and a pair of wheels of a water braked vehicle. The invention additionally relates to a computer program, a computer readable medium and a control unit related to said method. [0002] The invention can be applied to heavy vehicles such as trucks, buses and construction equipment. Although the invention will be described in relation to a truck, the invention is not limited to this particular vehicle, but may also be used with other vehicles such as cars. Background technique [0003] The vehicle industry is working hard to reduce CO 2 emission. Various alternatives to diesel and gasoline have been developed for powering vehicles. One such alternative is battery electric vehicles (BEVs). Another alternative is to ...
