Abstract
A method for operating a vehicle having an automatic, continuously variable speed transmission comprising at least three control phases. During a first control phase, the engine speed is maintained at a substantially constant value while the transmission gear ratio is increased to the maximum transmission gear ratio. During a second control phase, the transmission gear ratio is maintained at the maximum transmission gear ratio while the engine speed is increased to the maximum engine speed possible at the maximum gear ratio and selected throttle valve angle. During a third control phase, the transmission gear ratio is decreased from the maximum transmission gear ratio, so that higher vehicle traveling speeds may be obtained. During the third control phase the transmission gear ratio may be rapidly changed to a ratio corresponding to maximum engine power when the accelerator pedal is placed in a kickdown position. Increased force on the accelerator pedal may be required to place the accelerator pedal in the kickdown position.
