Abstract:
A vehicle control system includes an accelerator sensor which detects an accelerator opening, and a processor which sets a target acceleration of a vehicle based on the detected accelerator opening, sets a target torque of a drive source based on the set target acceleration, and controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the processor sets the target acceleration such that the depression-increasing target acceleration and the pedal-returning target acceleration are different from each other in a predetermined range of an upper limit acceleration or less and a lower limit acceleration or greater.
