VEHICLE TRAVEL CONTROL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a vehicle travel control apparatus for implementing travel control such that during acceleration, a predetermined speed is reached without starting the engine, while increasing the amount of regenerative energy collected during deceleration to improve fuel economy.SOLUTION: A vehicle travel control apparatus 100 for controlling vehicle speed mounted on a hybrid vehicle with an engine 107 and a motor 112 as power sources includes: a target vehicle speed computing part 200 for calculating a target vehicle speed; an acceleration command value calculation part 201 for calculating an acceleration command value 211 based on the target vehicle speed; an acceleration limit processing part 203 for calculating a limited acceleration command value 214 by limiting the acceleration command value 211 with a predetermined upper-limit value and a lower-limit value; a torque command value computing part 205 for calculating a torque command value from the limited acceleration command value 214; and a speed-change command value computing part 206 that determines the need for downshift on the basis of the acceleration command value 211 and an upper-limit torque or a lower-limit torque of the motor, and that computes a speed-change command value 215.
