    摘要： An input shaft rotating speed detector detects an input shaft rotating speed Nin of an automatic transmission based on output signals from a resolver within a predetermined time period δt1. An output shaft rotating speed detector calculates the number of pulse signals output from an electromagnetic pickup sensor within the predetermined time period δt1, to detect an output shaft rotating speed Nout of the automatic transmission based on the time length of pulse intervals in the calculated number of pulse signals. With this configuration, the number of pulse signals used for calculating the output shaft rotating speed Nout can be changed, to thereby make a detection period of the output signals from the resolver used for calculating the input shaft rotating speed Nin be consistent with that of the pulse signals used for calculating the output shaft rotating speed Nout.

    摘要： A control system for hybrid vehicles in which an electric prime mover is connected to an output shaft through a transmission, comprising: a running state judging means for judging whether or not a downshifting is being carried out to increase speed change ratio of the transmission while a vehicle is coasting; a creep torque lowering means for lowering creep torque generated by the electric prime mover, in case the running state judging means judges that the downshifting is being carried out; a speed change termination judging means for judging a termination of the downshifting; and a creep restoring means for raising the lowered creep torque to the previous level subsequent to the termination of downshifting, at a timing which is delayed in comparison with a timing when the torque is raised due to a torsional vibration arising from the downshifting.

    摘要： The hybrid vehicle is provided with a power distribution mechanism (20) distributing a power of an internal combustion engine (16) to a wheel side output shaft (6) and a first motor generator (18), and a transmission (14) transmitting a power of a second motor generator (12) to the wheel side output shaft (6). An electronic control unit (30) executes a rotation synchronization control for synchronizing a rotation speed of the second motor generator (12) prior to the gear shift with a rotation speed after the gear shift at a time of gear shift of the transmission (14). In the case that a neutral request for shutting off a power transmission to the wheel side output shaft (6) is executed during an execution of the rotation synchronization control, an execution of the neutral control of shutting off the application of current to the first and second motor generators (18, 12) is inhibited until the execution of the rotation synchronization control is finished. It is thus possible to reliably suppress a shift shock of the transmission (14) generated by the shutoff of the application of current to the second motor generator (12) during the execution of the rotation synchronization control.
