发明名称 Apparatus and method for shifting into a lower gear of a manual transmission
摘要 A method and apparatus for controllably shifting into a lower gear of a manual transmission is disclosed. A high downshift speed value is established and stored in a memory. The downshift speed variable of the manual transmission is set equal to the high downshift speed value for a duration time in response to a control signal. The manual transmission is controllably shifted into a lower gear when an engine speed becomes equal to or less than the downshift speed variable.
