摘要: A vehicle including a battery (61) powering an electrical motor (60), the electric motor (60) operating when the vehicle is driving at a nominal speed in order to drive, at a constant speed, a variable displacement hydraulic pump (4) which is connected to at least one variable displacement hydraulic motor (3). The hydraulic motor indirectly drives wheels of the vehicle. The variable displacement pump is electronically controlled and managed by a circuit which monitors, manages and controls (9) an angle of a cam plate which controls variable displacement of hydraulic pump (4).
