摘要： A comprises a vehicle control unit, VCU, and a control module, CM, configured to control the torque actuators. The VCU is configured to send to the CM a parameter request and a desired recuperation power or a desired parameter split ratio. If the CM determines that these are conflicting targets, then based on one or more predefined criteria, the CM will apply a parameter value and allocate a recuperation power or a parameter split ratio such that the applied parameter value is different from the requested one and/or the allocated recuperation power or parameter split ratio is different from the desired one. A method of controlling a wheel is also disclosed.

摘要： A device for enabling SOC estimation of at least one battery cell in an electrical energy storage system of a hybrid electric vehicle. The device initiates charging of the battery cell to a first voltage level. The battery cell is charged by an electric machine powered by a combustion engine. The device detects that the first voltage level is reached, initiates stop of fuel injection to the combustion engine. The device initiates discharging of the at least one battery to a second voltage level. The device detects that the battery cell has been discharged to a second voltage level. SOC estimation of the battery cell is enabled when the second voltage level has been reached.

摘要： The invention relates to an air-actuated vehicle system, comprising an actuating device which houses a pressurizable chamber, a pressurized air source, a conduit extending between the pressurized air source and the actuating device, for enabling the pressurizable chamber of the actuating device to be pressurized with air from the pressurized air source, and a pressure sensing arrangement measuring a first pressure inside the pressurized air source and a second pressure inside the pressurizable chamber, wherein the pressure sensing arrangement is configured to determine that the system has an air leakage when the result of the measurement(s) of said second pressure deviates from an expected result, wherein the expected result is based on the result of the measurement(s) of said first pressure. The invention also relates to a method of leakage detection.

摘要： A method for diagnosing a part of a crank case ventilation system of an engine operable in different engine running conditions, the system comprising an electrically driven crank case ventilation, eCCV, separator. The method comprises determining a compared power consumption of the eCCV separator by comparing a current power consumption indicative value of the eCCV separator with a reference value; determining whether or not the compared power consumption achieved as pre-set criteria; and diagnosing a fault in the system in response to determining that the compared power consumption achieves the pre-set criteria.

摘要： A method for determining a lidar sensor pose with respect to a predefined map image, comprising acquiring a lidar height map; determining an optical flow field, which relates the lidar height map and the map image; and computing a maximum-likelihood/ML estimate of the lidar sensor pose on the basis of the determined optical flow field. The optical flow field may optionally be determined by a regression model, which additionally produces an associated variability tensor to be used in the ML estimation. In particular, the optical flow field may be determined by a trained neural network.
