The invention relates to a method for controlling a driveline (10) of a vehicle (1), wherein the driveline (10) at least comprise a clutch (12) and a transmission (13), where the clutch (12) is adapted to connect the transmission to an propulsion unit (11). The method comprises the steps of;—estimating (105) an upcoming clutch temperature at least dependent on an imminent drive route, and if (106) the estimated upcoming clutch temperature is above a threshold value (T);—controlling (107) the driveline (10) in a critical heat mode, wherein in the critical heat mode the transmission (13) is controlled such that a clutch temperature increase is lower in comparison to a normal driveline control mode.

A system and method are arranged to provide recommendations to a user of a vehicle. In one aspect, the vehicle navigates in an autonomous mode and the sensors provide information that is based on the location of the vehicle and output from sensors directed to the environment surrounding the vehicle. In further aspects, both current and previous sensor data is used to make the recommendations, as well as data based on the sensors of other vehicles.

The invention relates to a method for a control unit (10) for stopping a vehicle (1) when stopping at different types of stop positions (2, 3, 4), the method comprising the following steps: —(S1) the control unit receiving input about a specific stop position for the vehicle, associated with when the vehicle is about to stop during a stopping sequence, the input being indicative of whether the specific stop position requires a high-precision stop or if a stop with a lower precision can be used; and —(S2) when the stop position requires a high-precision stop, the control unit controlling the stopping sequence such that the vehicle stops with a first stopping precision level with respect to the specific stop position, and when a lower precision can be used for the stop, the control unit controlling the stopping sequence such that the vehicle stops with a second stopping precision level which is lower than the first precision level. The invention further relates to a control unit and to a vehicle comprising the control unit.

An apparatus including a transmission mechanism in a power transfer path between a drive source and wheels; an oil pressure control device supplying lubricating oil to the transmission mechanism; and a control part outputting an electrical instruction to increase a flow rate of the supplied lubricating. When the control part outputs an electrical instruction to the oil pressure control device to increase a flow rate of lubricating oil supplied to the transmission mechanism, and determines that the flow rate of lubricating oil supplied to the transmission mechanism from the oil pressure control device does not increase as indicated by the electrical instruction (time t1), the control part considers that the oil pressure control device is in an abnormal state, and can impose a limitation that an absolute value of torque of the transmission mechanism transferred between the wheels and the drive source be reduced (time t1-t5).

Systems and methods for operating a vehicle that includes an engine and an electric machine are described. In one example, torque requests are aligned in time to compensate for a delay that may be caused by broadcasting one or more torque commands over a controller area network or another type of communication link. The torque requests may be aligned via delaying an engine torque request and predicting an electric machine torque.

A smart driveline disconnect assembly having a torque coupling assembly, an actuator, at least one sensor and a controller is provided. The torque coupling assembly is configured to selectively couple torque between a transmission and a final drive assembly. The actuator is configured to activate the torque coupling assembly. The at least one sensor is used to generate sensor information. The controller is configured to control the actuator based at least in part on the sensor information. The controller is further configured to determine at least a thermal energy level associated with the torque coupling assembly based on the sensor information and at least in part control the actuator based on the determined estimated thermal energy level.

A vehicle control system that ensures a sufficient distance to empty in the event of a failure of a clutch for changing an operating mode of a vehicle. The control system is configured to: determine a reduction in performance of the clutch based on a value of a parameter for determining a performance of the clutch; and select the operating mode in which a distance to empty is longer and inhibit to actuate the engagement device, when a reduction in performance of the engagement device is determined.

The disclosure relates to a method for controlling a driveline (10) of a vehicle (1), wherein the driveline (10) at least comprises a transmission (13) and a clutch (12), wherein the clutch (12) is adapted to be provided between the transmission (13) and a propulsion unit (11) of the driveline (10), wherein the method comprises the steps of; predicting an imminent drive route, identifying if the imminent drive route comprises any clutch severity classification (CSC), and if the imminent drive route comprises a clutch severity classification (CSC)—estimating (103) an expected clutch temperature (Tic) dependent on at least the clutch severity classification (CSC) and one vehicle parameter (Vp), wherein, the clutch severity classification (CSC) is at least dependent on an inclination of the imminent drive route, and if (105) the expected clutch temperature (Tic) is above a clutch temperature threshold value (Tt); controlling (106) the driveline (10) in a critical heat mode, wherein in the critical heat mode the transmission (13) is controlled such that a clutch temperature increase is lower in comparison to a normal driveline control mode.

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.
