Abstract:
Creep control is performed, in response to an accelerator-off operation, to control a second motor to cause a predetermined creep torque Tcr to be output from the second motor to a driveshaft. First creep cut-off control is performed, in response to a brake-on operation during the creep control, to control the second motor to cause a torque reduced from the creep torque Tcr at a high rate by a predetermined high variation ΔThi to be output from the second motor to the driveshaft. Subsequent to the first creep cut-off control, second creep cut-off control is performed to control the second motor to cause a torque reduced at a low rate by a predetermined low variation ΔTlow smaller than the predetermined high variation ΔThi to be output from the second motor to the driveshaft.
