The present invention is an electrical control apparatus for control of a manual transmission apparatus in a motor vehicle. The transmission state is selected by clockwise or counter-clockwise motion of a shift select lever via a first motor and forward or rearward motion of the shift select lever via a second motor. The electrical control apparatus includes first set of microswitches for indicating the left, center, right location of the shift select lever, and a second set of microswitches for indicating the forward, neutral or rearward location of the shift select lever. A logic control unit generates 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. The control apparatus also includes a motor drive circuit for controlling the first and second motors in response the sequence of drive signals.

Electronic control system for control of electronic electric shift

An electric shift apparatus for controlling a motor vehicle manual transmission. The apparatus includes a power module adapted to be bolted to the housing of the transmission, a control module adapted to be positioned in the passenger compartment of the vehicle, and a gear selector assembly positioned on the steering column assembly of the vehicle. The operator selects a transmission position by movement of an appropriate gear lever on the steering column, a signal corresponding to the selected position is transmitted to the control module, the control module compares this signal to a signal provided by limit switches in the power module indicating the instantaneous position of the transmission, and the control module generates a signal to the power module coded to impart the specific combination and sequence of crossover and shift movements to the transmission select lever required to move the select lever from its indicated crossover and shift position to the crossover and shift positions corresponding to the operator selected position. The required linear movement of the shift lever is provided by a ball screw assembly powered by a first electric motor and the required angular or crossover movement of the select lever is provided by a speed reduction unit driven by a second electric motor.
