Abstract

The invention can be applied to its specific vehicle types. Control unit (16) adjusts the shaft rotation speed of electric motor 1(13) and electric motor 2(15) in accordance with driving control data (17). While electric motor 1(13) is responsible for forward-backward motion of the vehicle, electric motor 2(15) provides right-left cornering to the vehicle. This cornering is made possible with the change in rotational speed between side wheels (2,3). Directional control via the side wheels (2,3) will not be sufficient for vehicle control at high speeds. For this purpose, a hydraulic system functioning dependent to the side wheels (2,3) is formed. The pulling force generated between the hydraulic cylinder (20) and the end of the hydraulic piston rod (20a) is used to control the direction of the front wheel (1) and/or rear wheel (4) of the vehicle.

Dependent claims

The invention is the full control of the vehicle motion and it has;

electric motor 1 (13) whose main function is to provide forward-backward motion of the vehicle, it has a double shaft, one of which is mounted to speed reducer (12) and the other shaft is mounted to AR input 1 (14a),
electric motor 2 (15) whose main function is to provide right-left cornering of the vehicle and it is mounted on AR input 2 (14b),
Addition reducer (14) which is used to change the side wheel speed in accordance with the speed of electric motor 2 (15),
speed reducer (12) which is used because speed is changed from AR input 1 (14a) to AR output (14c) and it (12) provides the same speed change on the other side wheel, and in addition, it has the same gear ratio as the gear ratio from AR input 1 (14a) to AR output (14c),
control unit (16) that adjusts the speed control of electric motor 1 (13) and electric motor 2 (15) in accordance with driving control data (17),
hydraulic system that is used in the direction control of the front wheel (1) and/or rear wheel (4).
