A method and apparatus are provided for optimizing one or more object detection parameters used by an autonomous vehicle to detect objects in images. The autonomous vehicle may capture the images using one or more sensors. The autonomous vehicle may then determine object labels and their corresponding object label parameters for the detected objects. The captured images and the object label parameters may be communicated to an object identification server. The object identification server may request that one or more reviewers identify objects in the captured images. The object identification server may then compare the identification of objects by reviewers with the identification of objects by the autonomous vehicle. Depending on the results of the comparison, the object identification server may recommend or perform the optimization of one or more of the object detection parameters.

Operating a drive train of a vehicle having a clutch assembly, wherein the clutch assembly is actuatable via an actuating device for the switchable transmission of a torque, wherein a first state of the actuating device, and thus a second state of the clutch assembly, is settable via a position of a drive unit of the actuating device, comprises: a) determining that a first torque request to the clutch assembly is constant; and b) determining that a first position of the drive unit is constant within the interval; and then c) controlling the drive unit with a dither function, wherein a position of the drive unit is continuously varied about the first position; and d) ending the dither function when the conditions stated in steps a) and b) are no longer met.

A wheel loader includes a forward clutch, an accelerator pedal, a brake pedal, and a controller configured to control hydraulic pressure of hydraulic oil supplied to the forward clutch. The controller performs clutch hydraulic pressure control for reducing the hydraulic pressure of the hydraulic oil supplied to the forward clutch according to an operation amount of the brake pedal on condition that at least the brake pedal is operated while the accelerator pedal is being operated. The controller continues the clutch hydraulic pressure control even after the clutch shifts from a complete engagement state to a semi-engagement state by the clutch hydraulic pressure control.

A method for operating a drive device for a motor vehicle, which has an internal combustion engine and an electric motor. A drive shaft of the internal combustion engine can be coupled to a motor shaft of the electric motor by a shift clutch. The shift clutch is adjusted to a desired clutch torque over a dragging period for startup of the internal combustion engine. Prior to the startup, a quantity of heat that is expected to accrue in the shift clutch during the startup is predicted and, when the predicted quantity of heat exceeds a limit value, at least one operating parameter of the drive device that influences the startup is chosen in such a way that the quantity of heat expected to accrue is reduced.

A method for controlling a hybrid vehicle may include detecting, in a controller, a circumstance that a vehicle is rapidly decelerated and then rapidly accelerated; confirming that a transmission clutch slipped in the controller as a result of performing the detecting; reducing a driving torque and a motor speed while minimizing a hydraulic pressure of the transmission clutch in the controller, in the case that the transmission clutch has slipped as a result of performing the confirming; determining when the transmission clutch is available for synchronization in the controller while performing the reducing; and normalizing the hydraulic pressure of the transmission clutch and the driving torque in the controller, in the case that it is determined that the transmission clutch is available for synchronization as a result of performing the determining.

The present disclosure relates to a hybrid vehicle and a method of controlling the same. The hybrid vehicle includes a battery configured to store electrical energy, a motor configured to rotate using the electrical energy, a transmission including a first clutch and a second clutch that are connectable to the motor, and a controller configured to control rotation of the motor to cool the transmission when the transmission is determined to be in an overheated state.
