Abstract
A speed ratio control system for a stepless variable speed transmission of vehicles having an electronic fuel injection control system. A speed ratio control signal for controlling the speed ratio of the stepless variable speed transmission is produced from the output fuel injection control signal from the electronic fuel injection control system and a target fuel injection quantity signal from an electronic arithmetic unit which generates the target fuel injection quantity signal in response to a throttle opening indication signal. The output fuel injection control signal is compared with the target fuel injection quantity signal to generate the speed ratio control signal which controls the speed ratio of the stepless variable speed transmission until the fuel injection indicated by the fuel injection from the electronic fuel injection system becomes equal to the target fuel injection quantity.
