The controller controls the left and right outboard motors and a steering actuator under a second control different from the first control when receiving the bow turning signal after receiving the propulsion signal in the composite operation.
Abstract: A leaning vehicle includes an actuator control unit that causes an actuator to generate an actuator torque in a counterclockwise direction based on a bar-handle-rotation-moment change amount in the case where a bar-handle-rotation-moment change amount in the counterclockwise direction is generated by a rider performing one operation of a right-grip-pushing-force increasing operation, a left-grip-pulling-force increasing operation, a right-grip-pulling-force reducing operation, and a left-grip-pushing-force reducing operation. The actuator control unit causes the actuator to generate an actuator torque in a clockwise direction based on a bar-handle-rotation-moment change amount in the case where a bar-handle-rotation-moment change amount in the clockwise direction is generated by a rider performing one operation of a left-grip-pushing-force increasing operation, a right-grip-pulling-force increasing operation, a left-grip-pulling-force reducing operation, and a right-grip-pushing-force reducing operation.
