Abstract
A method of controlling actuation of torque transfer devices in a vehicle includes determining that a first torque transfer device and a second torque transfer device that are associated with a vehicle axle are in a disconnected state in which the torque transfer devices are not transmitting torque, comparing a driving parameter to one or more thresholds; and changing the first torque transfer device to a connected state when the driving parameter meets said one or more thresholds.
Claims17
A method of controlling actuation of torque transfer devices in a vehicle, comprising:
- determining that a first torque transfer device that is associated with a vehicle axle is in a disconnected state in which the first torque transfer device is not transmitting torque;
- determining that a second torque transfer device that is associated with the vehicle axle is in a disconnected state in which the second torque transfer device is not transmitting torque;
- comparing a driving parameter to one or more thresholds;
- and
- changing the first torque transfer device to a connected state when the driving parameter meets said one or more thresholds.
2 more elements
An assembly for a vehicle, including:
- a first shaft adapted to be coupled to a first wheel for rotation with the first wheel;
- a first torque transfer device having a connected state in which an input torque is sometimes transmitted through the first torque transfer device to the first shaft, and a disconnected state in which the input torque is not transmitted through the first torque transfer device to the first shaft;
- a second shaft adapted to be coupled to a second wheel for rotation with the second wheel;
- a second torque transfer device having a connected state in which an input torque is sometimes transmitted through the second torque transfer device to the second shaft, and disconnected state in which the input torque is not transmitted through the second torque transfer device to the second shaft;
- an accelerometer having an output that corresponds to a lateral acceleration of the vehicle;
- a control system connected to the accelerometer, the first torque transfer device and the second torque transfer device, wherein the controller controls a change of the state of one or both of the first torque transfer device and the second torque transfer device between the connected and disconnected states, and wherein the controller is responsive to the output of the accelerometer to change one of the first torque transfer device and the second torque transfer device from the disconnected state to the connected state when the output from the accelerometer is greater than a first threshold.
