Electronic control system for control of electronic electric shift apparatus for manual transmission
An electrical control apparatus is described for control of a manual transmission apparatus in a motor vehicle having a plurality of transmission states selected by the position of a shift select lever, the electrical control apparatus comprising: a first electric motor; means drive by the first electric motor and operative in response to energization of the first electric motor to move the shift select lever laterally between left, center, and right locations; a second electric motor; means driven by the second electric motor and operative in response to energization of the second electric motor to move the shift select lever longitudinally between forward, neutral, and rearward locations; operator input means operative to generate a desired transmission sate signal corresponding to manual operator input; a first transmission state sensing means for indicating the left, center, or right location of the shift select lever; a second transmission state sensing means for indicating the forward, neutral or rearward location of the shift select lever; and a logic control unit connected to the operator input means and the first and second transmission state sensing means for generation of a sequence of motor drive signals corresponding to the sequence of motions required for movement of the shift select lever from the present transmission state to the desired transmission state when the desired transmission state differs from the present transmission state, the motor drive signals including a clockwise motor drive signal, a counter-clockwise motor drive signal, a shift up motor drive signal and a shift down motor drive signal.
