Abstract: A number N of position sensors, each associated with one of N shift rails in a shift rail transmission system, wherein the set of N sensors is divided into subsets and each subset is provided a common reference from a control module; and a processing component that determines from data from each sensor whether the shift rail associated with that sensor is in a position of engagement of a first gear, a position of engagement of a second gear, or in a neutral position. Further, providing a first common reference to a first set of shift rail position sensors; providing a second common reference to a second set of shift rail position sensors; receiving sensor data from each position sensor; determining that the data from the first set of position sensors is unreliable; and operating a transmission using only the gears related to the position sensors in the second set.

Abstract: An exemplary transmission system includes a plurality of sensors each configured to output a signal at least partially representative of a speed of at least one of a first transmission input shaft, a second transmission input shaft, a transmission output shaft, and an engine. A transmission control module is in communication with the plurality of sensors and is configured to identify at least one of the plurality of sensors as a failed sensor and another of the plurality of sensors as a working sensor. The transmission control module is further configured to estimate the signal of the failed sensor based on a predetermined relationship between an expected signal from the failed sensor and the signal received from the working sensor.

Abstract: A method is disclosed for controlling engine braking horsepower for a power transmission mechanism in a vehicle powertrain. The transmission mechanism has multiple-ratio gearing and a continuously variable transmission unit arranged in parallel disposition. A target engine speed during an engine braking mode is maintained by controlling the ratio of the continuously variable transmission unit.

Abstract: A system, storage medium, and method for controlling an engine in a vehicle which provides the operator with a particular operating capability for a specified time period, which time period is reestablished at a predefined interval, including determining whether the operator has tampered with the engine control system clock to obtain additional time for the particular operating capability. The system, storage medium, and method monitor the system clock and utilize one or more criteria to determine whether tampering has occurred. If the system clock has been tampered with, one or more additional steps are taken, including logging the tampering event, suspending any steps which would provide the particular operating capability to the operator for any additional time until the next interval, or until the engine has been returned to personnel authorized to reprogram the engine control.

Abstract: A method and system for detecting tampering with a vehicle speed sensor by calculating an average speed based upon global positioning system data. A first position of a vehicle is learned from a global positioning system at a first time. After a time interval the system learns a second position from the GPS at a second time. Based on this information, the average speed is calculated and is then compared to a maximum speed limit value. The system checks to determine if anyone has tampered with the GPS if no over speed condition is detected. If an over speed condition is detected or if there is an indication of tampering with the global positioning system, the system integrates a vehicle speed sensor tampering system that is either logged in memory or may be used to limit engine speed by controlling the engine control module.

Abstract: A method of acquiring population data from engine control modules provided with a memory for storing data relating to parameters of engine operation. The method includes the steps of downloading stored data from a plurality of engine control modules when the engine control modules are reprogrammed. A set of population data is developed and communicated to a central database. The population data is statistically analyzed when a statistically significant portion of the population is obtained. The statistical analysis of the population data is then used to make engine design modifications, provide warranty problem analysis, and analysis of optional feature acceptance.

Abstract: A system and method for controlling an engine in a vehicle which allows the vehicle operator to manually request a vehicle speed in excess of the established vehicle speed limit that includes establishing a normal vehicle speed limit, establishing a passing duration period, establishing a passing override reset interval, and controlling the engine in response to operator input to provide a greater vehicle speed for a cumulative period not greater than the passing duration period at any time during the passing override reset interval. The system and method may include the capability of establishing a passing speed increment and controlling the vehicle speed during passing to limit the vehicle to a speed not exceeding the normal vehicle speed limit plus the passing speed increment.

Abstract: A supported transition metal composition is obtained by suspending a support material in an inert liquid medium, spraying the suspension, collecting a solid material and contacting the sprayed solid with a transition metal compound. The support material may be a metal halide such as magnesium chloride or an inorganic oxide such as silica or alumina. In addition to being contacted with the transition metal compound, the support material may be contacted either before or after the spraying step with other reagents such as organo metallic compounds, halogen compounds, or Lewis Base compounds. The product obtained after contacting with the transition metal compound may be used as a component of a polymerization catalyst system to polymerize an unsaturated monomer such as ethylene or propylene.

Abstract: A solid material which is a transition metal composition, or a support for a transition metal compound, is suspended in a liquid medium, the mixture is subjected to mechanical action and the treated mixture is spray-dried. If the solid is a support material, it is subsequently contacted with a transition metal compound. The mechanical action can be a grinding process or a process providing simultaneous vigorous agitation and a shearing action. The transition metal composition may be used with an organic metal compound to polymerize an unsaturated monomer to give a polymer of good particle form.
