Abstract:
The present invention provides a method of reducing the output speed of a transmission in a vehicle, whereby the transmission includes a speed sensor and a controller and the vehicle includes a proximity sensor. The method includes measuring the output speed with the speed sensor and comparing the measured output speed to an output speed threshold. The controller receives throttle percentage and compares the throttle percentage to a throttle threshold. The method further includes receiving an input signal from the proximity sensor and comparing the input signal to a signal threshold. The output speed of the transmission can be controlled based on the values of the measured output speed, throttle percentage, and input signal.
