Patent application number | Description | Published |
20120152049 | GEAR ABSOLUTE POSITION SENSOR FOR MANUAL TRANSMISSION - The present invention provides a gear absolute position sensor assembly (GAPS) that senses the current absolute, position of the shift lever of a manual transmission. The sensor assembly provides data to an associated electronic controller such as an engine control module (ECM) regarding the current position of the shift lever, such as an engaged gear. The sensor assembly preferably comprises two Hall effect or other type of magnetic field (proximity) sensors in combination with an application specific integrated circuit (ASIC) which is supplied with data from the sensors, decodes the output of the sensors and provides an output identifying a specific engaged gear or neutral for use by vehicle or engine management electronics. The sensors are mounted proximate the shift linkage at a location where they can sense both rotation and translation. | 06-21-2012 |
20120158270 | ACTIVE FUEL MANAGEMENT SYSTEMS AND METHODS FOR VEHICLES WITH A MANUAL TRANSMISSION - A system for a vehicle includes an active fuel management (AFM) module, an expected engine speed determination module, and a disabling module. The AFM module selectively cuts off fuel to at least one cylinder of an engine and maintains valves of the at least one cylinder in closed positions. The expected engine speed determination module determines an expected engine speed based on a position of a shift lever of a manual transmission measured using a position sensor module. The disabling module selectively disables. the AFM module based on the expected engine speed. | 06-21-2012 |
20120234131 | DUAL-MASS FLYWHEEL LOCK-OUT CLUTCH - A dual-mass flywheel is provided for a vehicle drivetrain having an internal combustion engine and a transmission. The dual-mass flywheel includes a primary mass adapted for connection to the engine and a secondary mass operatively connected to the primary mass and adapted for connection to the transmission. The clutching mechanism is configured to lock the secondary mass to the primary mass up to a threshold speed of the engine to reduce noise, vibration, and harshness (NVH) during start up of the engine. The clutching mechanism is also configured to release the secondary mass from the primary mass above the threshold speed. A motor vehicle employing the disclosed dual-mass flywheel is also provided. | 09-20-2012 |
20130060436 | SYSTEM AND METHOD FOR CONTROLLING LOADS ON A MANUAL TRANSMISSION BASED ON A SELECTED GEAR OF THE MANUAL TRANSMISSION - A system according to the principles of the present disclosure includes a selected gear module and a shift indicator module. The selected gear module determines a selected gear of a manual transmission. The shift indicator module monitors vehicle speed and the selected gear and generates a shift indicator signal based on the vehicle speed and the selected gear, the shift indicator signal indicating when to shift to one of first gear and reverse gear. | 03-07-2013 |
20130080001 | SYSTEM AND METHOD FOR CONTROLLING LOADS ON A DUAL MASS FLYWHEEL ATTACHED TO AN ENGINE BASED ON ENGINE SPEED - A system according to the principles of the present disclosure includes an engine speed module and a downshift indicator module. The engine speed module determines an engine speed when a clutch is engaged with a dual mass flywheel. The downshift indicator module generates a downshift indicator signal when the engine speed is less than a first speed, the downshift indicator signal indicating when to downshift a manual transmission. | 03-28-2013 |
20130240319 | TRANSMISSION CLUTCH WITH IMPROVED COOLING - A clutch for a manual or automatic transmission according to the present invention includes an axial fan or turbine disposed on a shaft extending between the clutch and the transmission. Air is supplied to the turbine through one or more radial passageways between the clutch and transmission housings and is provided through an annular passageway around the shaft. Air from the annular passageway is then dispersed generally radially between the clutch plates or disks and other clutch components to absorb and carry away heat generated during clutch operation. | 09-19-2013 |
20130300403 | GEAR ABSOLUTE POSITION SENSOR FOR MANUAL TRANSMISSIONS - The present invention provides a gear absolute position sensor assembly (GAPS) that senses the current absolute, position of the shift lever of a manual transmission. The sensor assembly provides data to an associated electronic controller such as an engine control module (ECM) regarding the current position of the shift lever, such as an engaged gear. The sensor assembly preferably comprises at least one Hall effect or other type of magnetic field (proximity) sensors in combination with an application specific integrated circuit (ASIC) which is supplied with data from the sensors, decodes the output of the sensors and provides an output identifying a specific engaged gear or neutral for use by vehicle or engine management electronics. The sensors are mounted proximate the shift linkage at a location where they can sense both rotation and translation. | 11-14-2013 |
20130306429 | CLUTCH ASSEMBLY WITH AN ENERGY CONTROL PLATE - A clutch assembly includes a housing, a clutch pack disposed within the housing and concentrically about a shaft, a clutch slave cylinder disposed between the clutch pack and the housing and concentrically about the shaft, and an energy control plate disposed between the clutch slave cylinder and the housing and concentrically about the shaft. The clutch slave cylinder and the energy control plate are generally secured to the housing with a set of fasteners | 11-21-2013 |
20140256509 | REMOTE START FOR MANUAL TRANSMISSIONS - A remote start vehicle system for a vehicle is provided. The system includes a remote start requester configured to request that the engine be started. The remote start requester is operable to request that the engine be started when the remote start requester is located outside of the vehicle. A control module is configured to cause the engine to be started upon request from the remote start requester. A sensor assembly is configured to sense a neutral gear state of the transmission, where the neutral gear state indicates whether the transmission is in neutral. The sensor assembly is configured to communicate the neutral gear state to the control module. The control module is configured to prevent the engine from being started if the neutral gear state indicates that the transmission is not in neutral. A method of remotely starting an engine is also provided. | 09-11-2014 |
