<p>The invention describes a vehicle comprising an internal combustion engine, one or more hydraulic control circuits operatively connected to the internal combustion engine, wherein each hydraulic circuit is configured for controlling one or more devices of the vehicle and comprises at least one hydraulic pump capable of transforming the mechanical energy drawn from the internal combustion engine into hydraulic energy, the mechanical energy consisting of a variable amount of the drive torque absorbed by the hydraulic pump, and an electronic control unit capable of managing and/or calculating a plurality of information and parameters regarding the operation of the on board vehicle devices, wherein the information and the parameters are detected by a plurality of sensors present on board of the vehicle and are thus sent to the electronic control unit through corresponding communication channels. At least one of the hydraulic circuits is provided with at least one block valve group capable of converting a part of the kinetic energy of the vehicle into hydraulic energy, through the pressure control exerted by the hydraulic pump on the fluid circulating in the hydraulic circuit, wherein the controlled variation of the pressure exerted by the hydraulic pump on the fluid circulating generates an amount of resistant torque applied to the internal combustion engine, converting the hydraulic energy into heat energy and thus determining a braking action of the vehicle, and at least one heat exchanger operatively connected to the hydraulic circuit, capable of dissipating the heat energy generated by the braking action caused by the block valve group.</p> |
