A controller detects partitioning lines OL and BL of a road and a road edge E based on an image taken by a camera, generates a pair of left and right virtual lines ILand ILthat extend from the side to the front of a vehicle along the partitioning lines OL and BL, controls the steering so the vehicle travels between the left and right virtual lines ILand IL, moves the left virtual line ILto a position in proximity to the road edge E and fixes the left virtual line ILto this position, and then, moves the right virtual line ILto a position separated from the left virtual line ILby the width of the vehicle and fixes the right virtual line ILto this position, and controls brakes to stop the vehicle after fixing the left and right virtual lines ILand IL.

Vehicle control system stabilizing behavior of a vehicle moving to a road edge to be stopped

A vehicle control method is applied to a vehiclein which a front wheelis driven by an engine, and the method includes a basic torque setting step of setting basic torque to be generated by the engine, based on an operational state of the vehicle; a deceleration torque setting step of setting deceleration torque, based on an increase in steering angle of a steering apparatusmounted on the vehicle; a torque generation step of controlling the engineso 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 wheeland an operation direction of the steering wheelwhen the steering angle is increased. Thus, vehicle posture control is performed in consideration of the vehicle-width-direction mounting position of the steering wheeland the operation direction of the steering wheel, so that a driver fatigue reduction effect of the vehicle posture control can be secured appropriately.

Vehicle control method, vehicle system, and vehicle control apparatus

A vehicle control method is applied to a vehiclein which a front wheelis driven by an engine, and the method includes a basic torque setting step of setting basic torque to be generated by the engine, based on an operational state of the vehicle; an acceleration torque setting step of setting acceleration torque, based on a reduction in steering angle of a steering apparatusmounted on the vehicle; a torque generation step of controlling the engineso 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 wheeland an operation direction of the steering wheelwhen the steering angle is reduced. Thus, vehicle posture control is performed in consideration of the vehicle-width-direction mounting position of the steering wheeland the operation direction of the steering wheel, so that a driver fatigue reduction effect of the vehicle posture control can be secured appropriately.

A control apparatus of a vehicle includes: a steering apparatus () including a steering wheel () operated in order to turn a vehicle () and a steering angle sensor () that detects a steering angle of the steering wheel (), the steering apparatus () steering a front wheel (steered wheel) () of the vehicle () in accordance with operation of the steering wheel (); and a controller () that sets a steering angle acceleration based on the steering angle detected by the steering angle sensor () and controls vehicle motion when the steering wheel () is operated to be turned. In particular, the controller () suppresses a rise of lateral acceleration of the vehicle () based on the steering angle acceleration in order to control the vehicle motion.
