Transmission ratio adjustment device for continuously variable transmission used for vehicle velocity regulation, has adjustment value provided by velocity regulator corrected by summation with stored value

摘要

The transmission ratio adjustment device is supplied with an adjustment value for the transmission ratio by a velocity regulator (18) comparing the actual and required vehicle velocities, with an adder stage (20) providing a corrected adjustment value, fed to a transmission ratio regulator by combining the initial adjustment value with a stored value for the transmission ratio.
