Abstract (en)
[origin: WO2010081948A1] Method for controlling a continuously variable transmission mounted between an internal combustion engine (5) of an automotive vehicle and the driven wheels (11), the continuously variable transmission being able to operate in at least one manual mode and an assistance mode. The control method involves the steps during which: - a first torque ratio corresponding to a CVT assistance mode is estimated, - a second torque ratio between the input torque and the output torque of the CVT is calculated at each moment, - the first and second ratios are compared, - from this, a limiting torque of the internal combustion engine is deduced.
