## Abstract

Embodiments of the present invention are directed to providing a transmission control system that enables an operator to quickly and effortlessly shift or change gears/selections/modes, in either a sequential or non-sequential manner without incurring the undesired unloading of driveline motion, while retaining consistent launches/start offs. More particularly, an improved transmission control system with an electronic gear shifter is presented for use in a vehicle or machine having an engine and transmission with a plurality of gear ratios or selections. The system allows the operator to shift gears/selections in a normal sequential progression or a progression that skips numerical order. Thus, the vehicle or machine may be accelerated and/or decelerated at a faster and more predictable rate to achieve greater performance in certain operating conditions.

## Claims

### Claim 1

A transmission control system for selecting modes sequentially or non-sequentially based on real-time conditions comprising:
an electronic mode selector;
a controller;
a driver board;
a communications means;
a valve block; and
one or more mode change components selected from the group comprising solenoids, servos, actuators and linkages,
wherein said mode selector, said controller, said driver board, said communications means, said valve block and said one or more mode change components are operably connected to a transmission, and
wherein said controller is configured to:
(1) receive a mode selection signal from said mode selector,
(2) process the mode selection signal as a desired mode change,
(3) actuate the one or more mode changing components which correspond to said desired mode change in order to shift a current mode selection into a different mode selection;
wherein that different mode selection is a sequential/non-sequential mode with respect to the current mode selection.

### Claim 2 (depends on 1)

The system of claim 1, wherein said desired mode is a first gear ratio which is a different gear ratio than the present mode selection, said current mode selection being a second gear ratio.

### Claim 3 (depends on 1)

The system of claim 1, wherein said controller selectively actuates one or more transmission solenoids based, at least in part, on operators manual selection of the mode selector.

### Claim 4 (depends on 1)

The system of claim 1, wherein said controller selectively actuates one or more transmission solenoids based, at least in part, on throttle position.

### Claim 5 (depends on 1)

The system of claim 1, wherein said controller selectively actuates one or more transmission solenoids based, at least in part, on engine rpm.

### Claim 6 (depends on 1)

The system of claim 1, wherein said controller selectively actuates one or more transmission solenoids based, at least in part, on vehicle ground speed.

### Claim 7 (depends on 1)

The system of claim 1, wherein said controller selectively actuates one or more transmission solenoids based on sensor data from the group consisting of, but not limited to, operators manual selection of the mode selector, engine RPM data, throttle position data, ground speed data, current mode ratio, Hall Effect data, torque sensor data, vehicle weight, tire diameter, tire circumference, tire pressure, and any combination thereof.

### Claim 8 (depends on 1)

The system of claim 1, wherein said mode selector is actuated by the operator.

### Claim 9 (depends on 1)

The system of claim 1, wherein said mode selector is manually actuated.

### Claim 10 (depends on 1)

The system of claim 1, wherein said mode selector is manually chosen.

### Claim 11

A transmission control method for selecting different modes sequentially or non-sequentially based on real-time conditions, said method comprising the steps of:
receiving a mode selection signal from a mode selector,
processing the mode selection signal as a desired mode change,
actuating one or more mode change components, selected from the group comprising solenoids, servos, actuators and linkages, which correspond to said desired mode change in order to shift a current mode selection into a different mode selection; and
wherein that different mode selection is a sequential/non-sequential mode ratio move or mode with respect to the current mode selection.
