Abstract

A non-rail bound vehicle comprising at least two drive electromotors (8), the one thereof being provided for driving a driving wheel (12) on the left side of the vehicle and the other one thereof being provided for driving a driving wheel (12) on the fight side of the vehicle, characterized in that each of the two electromotors (8) has its own motor control (30) associated therewith for presetting the instantaneous nominal power and/or the instantaneous nominal speed of the respective electromotor (8); and that a superior central control (28) connected to the central controls (30) is provided which controls the two electromotors (8) via the motor controls (30) so as to prevent drive slip and/or brake locking and/or to provide a fight/left drive differential that is favourable in terms of movement dynamics, with the central control (28) and/or the motor controls (30) taking into account information on the instantaneous actual electrical power and/or the instantaneous actual speed of the two electromotors (8).
