To provide a constant speed travel controller for a hybrid vehicle capable of applying constant speed travel control, even when an input and an output for an engine system or a motor strong electric system are limited during the constant speed travel control.
In this constant speed travel controller for the hybrid vehicle having an engine 301 and a driving motor 303 as a driving source, and provided with a constant speed travel control means for traveling while controlling an output torque and a braking torque to maintain a vehicular speed set by a driver, the constant speed travel control means is set to neglect an input and output limit value for the motor strong electric system, when the constant speed travel control is started, and for setting an output torque upper limit value to an engine torque upper limit value.
