<P>PROBLEM TO BE SOLVED: To provide a torque distribution controller for a hybrid vehicle capable of maintaining a stable vehicle behavior when a motor system is turned off, even when a failure of a heavy electrical system is detected during execution of torque distribution control using an output torque of a motor. <P>SOLUTION: This torque distribution controller for the hybrid vehicle provided with the heavy electrical system having an engine and the motor as driving sources, and connected electrically to the motor, and a torque distribution control means for controlling at least one out of a front-rear wheel torque distribution and a right-left wheel torque distribution, using the output torque of the motor, is provided with a heavy electrical system failure detecting means (step S1) for detecting the occurrence of the failure required to prohibit power supply and discharge/charge for the heavy electrical system, and the torque distribution control means (Fig.2) is constituted not to limit the output torque of the motor until a torque distribution difference reaches a specified value or less, when it is necessary to prohibit the power supply and the discharge/charge for the heavy electrical system, by the detection of the failure in the heavy electrical system. <P>COPYRIGHT: (C)2007,JPO&INPIT |
