Vehicle control system and vehicle control method

A vehicle control method executed by a control device in a vehicle including a drive source that generates a driving force of the vehicle, an accelerator opening degree sensor that detects an accelerator opening degree that is an opening degree of an accelerator pedal included in the vehicle, and the control device configured to control the drive source based on the accelerator opening degree detected by the accelerator opening degree sensor, the method comprising:

• performing a first control that sets a target acceleration that increases in accordance with an increase in the accelerator opening degree and controls a torque of the drive source based on the set target acceleration;
• performing a second control that sets a target acceleration that increases at a rate of change greater than the target acceleration applied in the first control in order to increase a jerk of the vehicle within a range less than a predetermined jerk and controls the torque of the drive source based on the set target acceleration;
• and
• first performing the second control when a rate of change of the accelerator opening degree increases by a predetermined value or more in a state in which the vehicle is not accelerating, and performing the first control after the target acceleration set in the second control reaches a predetermined acceleration.
