CONTROL METHOD FOR VEHICLE, VEHICLE SYSTEM, AND VEHICLE CONTROLLER

In a control method for a vehicle and a vehicle controller that add deceleration to a vehicle so as to control a vehicle posture when a turning operation of a steering system is performed, the deceleration is appropriately set on the basis of an operation of a single pedal. The control method for the vehicle includes: a step of adding the deceleration that corresponds to an accelerator pedal depression amount to a vehicle when the accelerator pedal depression amount is smaller than a specified value A that is larger than 0; a step of determining whether the turning operation of the steering system is performed on the basis of a steering angle detected by a steering angle sensor ; a step of adding the deceleration to the vehicle so as to control the vehicle posture when it is determined that the turning operation of the steering system is performed; and a step of setting the deceleration added to the vehicle to a smaller value when the accelerator pedal depression amount is smaller than the specified value and is a first value than when the accelerator pedal depression amount is smaller than the specified value and is a second value (>the first value).
