Abstract: A control system of a vehicle comprises a torque sensor, a vehicle direction module, and a control module. The torque sensor determines a driveline torque signal based on a torque produced by a device of a driveline. The vehicle direction module determines whether a vehicle direction includes one of a forward direction and a reverse direction based on the driveline torque signal. The control module controls the vehicle based on the vehicle direction.

Abstract: A system and method for detecting vehicle movement based on the measurement of the torque value on a vehicle drivetrain is disclosed. The system includes a torque sensor for measuring the torque on a vehicle drivetrain. This measured torque is utilized by a control module, with various other measured vehicle parameters, to determine if the conditions are such that vehicle movement may occur or has already begun. Possible vehicle movement is indicated when either the measured torque value exceeds a threshold value and changes towards zero, or big noise spikes are present in the torque sensor output signal.

Abstract: A vehicle powertrain includes an engine capable of being selectively turned on and turned off, a transmission operatively connected to the engine, and a hydraulic control system including a pump in fluid communication with the transmission. The pump is operatively connected to the engine for supplying fluid to the transmission when the engine is on, wherein the pump is idle when the engine is off. The hydraulic control system additionally includes an accumulator arranged to accumulate the fluid when the engine is on. The accumulator is also controlled to accumulate fluid when the engine is on, to retain the fluid when the engine is turned off, and to discharge the fluid to the transmission when the engine is restarted.

Abstract: A method and apparatus provide control of a neutral idle (NI) clutch to allow a vehicle with automatic engine start-stop functionality to utilize the NI state as a transitional shift state, either upon or just prior to engine shutdown, to minimize driveline disturbances. By controlling the NI state, the vehicle driveline is decoupled and torque multiplication is prevented upon engine restart. Execution of an algorithm unloads the engine upon shutdown, and unloads or partially loads the engine as a designated NI clutch reapplies during an engine restart event. The NI clutch may be a component of a multi-speed automatic transmission, e.g., a 6-speed or an 8-speed transmission, having a plurality of torque transfer mechanisms or clutches. One of these clutches is designated as the NI clutch, and this designated NI clutch may be selectively actuated to enter the NI state in conjunction with engine shut down/restart.

Abstract: An assembly for positioning a torque sensor having a receiver and a transmitter is provided. The assembly includes a first annular member, wherein the receiver is coupled to the first annular member. A second annular member is disposed proximate the first annular member. A bearing assembly is disposed between the first annular member and the second annular member. The bearing assembly includes a first race formed to the first annular member, a second race formed to the second annular member, and a bearing disposed between the first race and the second race for allowing the first race and the second race to rotate relative to one another. A radially extending member is coupled to the second race. The receiver is radially displaced from the bearing assembly and the transmitter is mounted to a mounting surface of the radially extending member opposite the receiver at a predefined axial distance.
