<P>PROBLEM TO BE SOLVED: To realize a hybrid vehicle which performs an all wheel driving by which a more excellent travel performance is obtained by increasing the degree of freedom by changing torque distributions for the front and rear wheels or the right and left wheels. <P>SOLUTION: The driving force from an engine 1 is transmitted to driving systems 6, 7, 8A and 8B on the front wheel side and driving systems 10, 11, 12, 13, 14A and 14B on the rear wheel side through a center differential gear 4. The torque distribution ratios for the front and rear wheels being set by the center differential gear 4 are set to be eccentric to the front wheel, and a motor/generator 20 is connected with the driving systems on the rear wheel side. A driving force controlling section 30 controls an addition torque of the motor/generator 20 to the driving torque side or the regenerative braking torque side in response to detection signals from various sensors 41 to 44 which detect the travel state. Thus, the torque distribution ratio of the front wheel side and the rear wheel side is changed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
