The invention relates to a control device (HC) for operating one or more foot pedal control devices (26; 26) in a vehicle. According to the invention, the control device (HC) comprises means (11, 20, 22; 11, 21 23) for transmitting the movement and force, exerted by the driver by his/her own muscular strength on the actuator (13) of the control device (HC), hydrostatically to the foot pedal control device/devices (26; 27) of the vehicle. In a preferred embodiment of the invention, the actuator (13) is arranged to act on the brake pedal (16) by means of an independent hydraulic circuit (18, 20, 22) when the driver moves/turns said actuator (13) in a first direction (B), and the actuator (13) is arranged to act on a second independent hydraulic circuit (19, 21, 23) when the driver turns/moves the actuator (13) in the opposite direction (C).
