| 20160146336 | APPARATUS AND METHOD FOR GEAR DETECTION - A method and apparatus is disclosed for determining the available gears of a geared vehicle based on the ratios of vehicle speed to engine speed, together with a method and apparatus for determining the current gear in which a geared vehicle is being driven based on the current ratio of vehicle speed to engine speed. | 05-26-2016 |
| 20160146339 | Powertrain Control Based On Bearing Speed - A speed sensor is integrated with a bearing of a transmission. The speed sensor may sense rotation of a bearing cage using a proximity sensor or may sense passage of the rolling elements themselves using an acceleration sensor. The speed of the shaft supported by the bearing is calculated from the speed sensor reading. The shaft speed may be used to control a slipping clutch during a shift event. When the transmission is in a fixed gear ratio, inconsistent speed sensor reading may indicate a preload issue. | 05-26-2016 |
| 20160146340 | AUTOMATIC SHIFT CONTROL SYSTEM - In the event of a failure to detect an operation position Psh, a shift command to a forward gear position (in this embodiment, the second-speed gear position “2nd” and the eight-speed gear position “8th”) established in association with an engagement device (in this embodiment, a brake B | 05-26-2016 |

| 20160159357 | SYSTEM AND METHOD FOR GENERATING VACUUM VIA AN ENGINE - Methods and systems for improving vacuum generation for an engine that may be operated at higher altitudes are presented. In one non-limiting example, a transmission that is mechanically coupled to the engine may be shifted from a gear to neutral in response to an actual total number of times a vehicle brake pedal is applied and partially released while the vehicle is stopped and the brake pedal is applied. | 06-09-2016 |
| 20160159363 | Torque Converter Having Variable Pitch Stator and Bypass Clutch - A transmission includes a torque converter with both a variable pitch stator and a bypass clutch. These are controlled in two modes to maintain a target slip speed. In a first mode, the bypass clutch is fully released and slip is controlled by varying the pitch of the stator blades. In a second mode, the stator is held in the tightest position and slip is controlled by varying the torque capacity of the bypass clutch. The target slip is calculates based on a variety of different input signals depending on what type of vehicle maneuver is being performed. | 06-09-2016 |
