Abstract
A control system for a continuously variable automatic transmission for an automotive vehicle, includes a throttle opening sensor that detects a throttle opening, and a controller that executes a change-speed control in a normal mode in which a desired transmission input speed is determined based on operating conditions of the vehicle and a desired transmission ratio is determined based on the desired transmission input speed when the throttle opening is less than a first value, and that executes the change-speed control in a linear mode in which the desired transmission ratio is fixed to a second value when the throttle opening is greater than or equal to the first value. The second value is set based on the desired transmission ratio used in the normal mode prior to switching to the linear mode.
