A rolling vehicle comprising:
- a chassis equipped with at least one pair of drive wheels and a system controlling the rotational driving of the drive wheels of the or of at least one of the pairs of drive wheels, said control system having at least two motors and a control device for each motor, said motors being capable of allowing, for one, the rotational driving of one of the drive wheels, and for the other, the rotational driving of the other of the drive wheels of the pair of drive wheels, each control device having a lever controlling the direction of rotation and the speed of rotation of the motor associated with said control device and a first sensor, said lever being a pivoting lever with an active state and an inactive state, said lever being, in the so-called active state, mounted, from a so-called neutral position, to be mobile by pivoting about a first pivot axis in a first, so-called forward direction, for a forward drive control at a variable speed of the associated motor, and in a second, so-called reverse direction, opposite the first direction, for a reverse drive control at a variable speed of the associated motor, this lever being, in the active state and in neutral position, further mounted to be mobile by pivoting about a second pivot axis within a range of displacement, in a way that is guided in displacement over a part of this range of displacement, for the switching of said lever from an active state to an inactive state in which any pivoting displacement of the lever about the first pivot axis is prevented, the first sensor being a sensor for detecting at least one position or range of positions of the associated lever within this range of displacement, this position or range of positions forming a position zone of the lever in which any pivoting displacement about the first pivot axis of the lever, which is guided in displacement, is prevented,
- wherein each control device comprises has a second sensor for detecting the angular position of said associated lever about said first pivot axis, a memory for storing the neutral position of said lever and a control unit configured to acquire the data from said second sensor and to, in the active state of the lever, control the speed and the direction of rotation of the associated motor as a function of the data from the second sensor and of the stored neutral position, and in that the vehicle has at least one operating mode, called calibration, in which the control unit is configured to order a storage of the neutral position corresponding to a datum supplied by the second sensor at least as a function of the data supplied by the first sensor.
