Full torque transmission control

In a motor vehicle having an internal combustion engine with a throttle, a transmission with a variable output-to-input speed ratio, and drive wheels coupled to the engine through such transmission, the improvement comprising

• a throttle control means connected to said throttle which puts said throttle in one of two positions, the first fully open and the second an idle position,
• a throttle and transmission control system including
• desired vehicle speed input means responsive to operator input producing a one time selected signal indicative of the drive wheel speed desired by the operator,
• actual vehicle speed means connected to said drive wheels for generating a signal proportional to the drive wheel speed of the vehicle,
• comparing means connected to said desired vehicle speed and actual vehicle speed means and to said transmission for comparing said desired speed means and said actual speed means and, responsive to results from such comparing, generating a control signal changing the output-to-input speed ratio of said transmission, said throttle control means being controlled automatically by the engine, and
• said transmission control system being arranged and connected to be effective independently of the one-time selected signal, when said throttle control means puts said throttle in full open position, to increase the output-to-input speed ratio of said transmission reducing the engine power output whenever said drive wheel speed is more than the indicated desired vehicle speed and to reduce the output-to-input speed ratio of said transmission increasing the engine power output whenever the drive wheel speed is less than the indicated desired speed.
