摘要： A vehicle control method is applied to a vehicle 1 in which a front wheel 2 is driven by an engine 4, and the method includes a basic torque setting step of setting basic torque to be generated by the engine 4, based on an operational state of the vehicle 1; an acceleration torque setting step of setting acceleration torque, based on a reduction in steering angle of a steering apparatus 5 mounted on the vehicle 1; a torque generation step of controlling the engine 4 so that torque based on the basic torque and the acceleration torque is generated; and an acceleration torque changing step of changing the acceleration torque, based on a vehicle-width-direction mounting position of a steering wheel 6 and an operation direction of the steering wheel 6 when the steering angle is reduced. Thus, vehicle posture control is performed in consideration of the vehicle-width-direction mounting position of the steering wheel 6 and the operation direction of the steering wheel 6, so that a driver fatigue reduction effect of the vehicle posture control can be secured appropriately.

摘要： A vehicle control method is applied to a vehicle 1 in which a front wheel 2 is driven by an engine 4, and the method includes a basic torque setting step of setting basic torque to be generated by the engine 4, based on an operational state of the vehicle 1; a deceleration torque setting step of setting deceleration torque, based on an increase in steering angle of a steering apparatus 5 mounted on the vehicle 1; a torque generation step of controlling the engine 4 so that torque based on the basic torque and the deceleration torque is generated; and a deceleration torque changing step of changing the deceleration torque, based on a vehicle-width-direction mounting position of a steering wheel 6 and an operation direction of the steering wheel 6 when the steering angle is increased. Thus, vehicle posture control is performed in consideration of the vehicle-width-direction mounting position of the steering wheel 6 and the operation direction of the steering wheel 6, so that a driver fatigue reduction effect of the vehicle posture control can be secured appropriately.
