  "textContent": "A control system controls the output of a power source of a vehicle having a continuously variable transmission and a gear ratio to be set by the continuously variable transmission. The control system determines a target driving force on the basis of an output demand and a vehicle speed, and determines a target output of the power source for achieving the target driving force. The control system determines a target output speed preset for the target output, and controls the gear ratio of the continuously variable transmission so that the actual output speed of the power source may become the target output speed. The control system further determines the target output torque of the power source on the basis of the target output and the actual output speed of the power source, and controls the power source to achieve the target output torque. When the gear ratio is to be changed, its changing rate is made different in at least two quick and slow states. Moreover, the target output speed is provided with an upper limit, which is changed.",
