Abstract: PROBLEM TO BE SOLVED: To suppress an electric motor from being excessively rotated when a vehicle jumps. SOLUTION: In a hybrid car where a first motor, an engine and a drive shaft are connected to a sun gear, carrier and ring gear of a planetary gear mechanism, and a second motor is connected to the drive shaft side, when it is decided that suspension stroke quantity SS has exceeded a threshold, and that a vehicle has jumped, a torque restriction coefficient α is set from 1 to 0 according to the elapsed time t, and the set torque restriction coefficient α is multiplied by request torque Td* requested for the drive shaft, and the calculated torque is set as performance torque T* (S350, S360), and when a predetermined time T1 elapses after the vehicle jumps, the engine independently operates, and the torque restriction coefficient α is set to 0, and the performance torque T* is set to 0 (S370, S380, S360). The engine and the two motors are restricted so that the performance torque T* can be output to the drive shaft. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle for suppressing power consumption while suppressing a shift shock in switching from a power interruption state to a power transmission state. SOLUTION: A hybrid control unit determines whether or not a deviation between the number of rotations Nm of a transmission member and the target number of rotations NmT is smaller than a threshold ΔN (S30) in an N range (YES, in S10). If the deviation between the number Nm and the number NmT is not smaller than the threshold ΔN (NO, in S30), the control unit executes rotation synchronous control (S40). Conversely, if the deviation between the number Nm and the number NmT is smaller than the threshold ΔN (YES, in S30), and the number Nm is within an upper and a lower limit values (YES, in S50), the control unit stops executing the synchronous control (S60).
