Abstract:
1. A vehicle travel control device that performs velocity following control so as to converge a velocity of a vehicle operated by a driver to a preset first target velocity, the device comprising: a designating unit that designates a reduction range in the velocity based on information obtained in advance related to the driver's operation if the velocity of the vehicle at start of the velocity following control is higher than the first target velocity; and a setting unit that sets a second target velocity lower than the first target velocity based on the reduction range designated by the designating unit and the first target velocity, wherein the information related to the driver's operation includes information related to at least one of an operation amount of a brake pedal, an operation change amount of the accelerator pedal, and a steering angle operation amount of a steering, the designating unit is configured to designate a small value for the reduction range if the operation amount of the brake pedal is large, designate a large value for the reduction range if the operation change amount of the accelerator pedal is large, and designate a large value for the reduction range if the steering angle operation amount of the steering is large, and the velocity following control is performed such that, if the velocity of the vehicle at start of the velocity following control is higher than the first target velocity, the second target velocity is set by operation of the designating unit and the setting unit, and the velocity of the vehicle is converged to the second target velocity and then converged to the first target velocity.
