1. A hydraulic module intended to be assembled on a hydraulic hybrid vehicle; the hydraulic module being sized, shaped, and adapted to be mounted beneath the floor of the vehicle; the hydraulic module forming a rigid and compact assembly, and comprising: a body comprising top and bottom surfaces, front and back surfaces, and opposed lateral sides; said body defining a pair of parallel, cylindrical passages extending between the opposed lateral sides;low and high pressure accumulators received in said passages; said low and high pressure accumulators being parallel and adjacent each other when received in said body; said low and high pressure accumulators defining a part of a hydraulic circuit when said hydraulic module is mounted to the vehicle to supply power to a traction motor of the vehicle;a hydraulic command block positioned on one of said opposed lateral sides of said body to be integrated into said module; said command block being directly connected to said low and high pressure accumulators via pressure lines:hydraulic couplings adapted to connect said hydraulic command block to the hydraulic circuit when said hydraulic module is mounted to the vehicle;lids which cover the lateral sides of the hydraulic module and extremities of said low and high pressure accumulators; said command block and said hydraulic couplings being enclosed by one of said lids; andsupports positioned along a periphery of the body, said supports forming substantially horizontal planes for mounting the body under the floor in the rear of the vehicle. 2. The hydraulic module according to claim 1 wherein said cylindrical passages, and hence said low and high pressure accumulators, extend transverse to an axis of said body. 3. The hydraulic module according to claim 2 wherein said high pressure accumulator and said low pressure accumulator are juxtaposed one behind the other in said body. 4. The hydraulic module according to claim 1, wherein the supports comprise discrete support elements, each support element comprising elastic means for fastening to the floor of the vehicle. 5. A hydraulic hybrid vehicle comprising the hydraulic module of claim 1. 6. The hydraulic hybrid vehicle according to claim 5, further comprising an “H” rear axle; said rear axle comprising a crossbeam mounted at opposite ends to longitudinal suspension arms, whereby the hydraulic module is mounted flat under a trunk of the vehicle, just behind the crossmember.
