Abstract

A vehicle travel control apparatus is provided that is capable of improving fuel economy by exerting control so as to attain a specified speed without starting the engine during acceleration, and by increasing the regenerative energy recovery amount during deceleration, during the travel control. A vehicle travel control apparatus (100) to control the vehicle speed is mounted in a hybrid vehicle containing an engine (107) and a motor (112) as power sources, and includes: a target vehicle computing unit (200) that calculates a target vehicle speed; an acceleration command value calculation unit (201) that calculates an acceleration command value (211) based on a target vehicle speed; an acceleration limit processing unit (203) that calculates a post-limit acceleration command value (214) that limits the acceleration command value (211) by utilizing a specified upper-limit value and a specified lower-limit value; a torque command value computing unit (205) that calculates a torque command value from the post-limit acceleration command value (214); and a speed-change command value computing unit (206) that determines whether a down-shift is required or not based on the acceleration command value (211) and an upper-limit torque or a lower-limit torque of the motor, and calculates a speed-change command value (215).
