A method is provided for operating a hybrid electric vehicle including an internal combustion engine and an electrical system, which electrical system includes at least one electronic control unit, an engine-driven electric machine (operable as a motor for driving the vehicle or as a generator for supplying power to one or more electrical loads via a high voltage traction bus, and a high voltage battery pack coupled to the high voltage traction bus by at least one contactor arranged to connect the battery pack to the high voltage traction bus. If it is determined that the at least one parameter indicates a condition preventing the battery pack from being connected to the high voltage bus, the electric machine is operated in voltage control mode during operation of the vehicle until the condition is eliminated, whereafter the high voltage bus is pre-charged and the high voltage battery pack reconnected.

Method and system are provided for vehicle route planning based on adaptive model predictive control. In one example, a method may include real-time online identification of the vehicle model base on the vehicle inputs and outputs; compression of the input space to increase the optimization efficiency; and optimization of the route planning based on the model parameter of the vehicle and the known road grade.

A vehicle safety assist system is configured to detect vehicles travelling ahead of a host vehicle and determine a relative kinematic property between a detected vehicle and the host vehicle and a relative kinematic property reliability measure indicative of a reliability of the determined relative kinematic property. The system is also configured, on the basis of host vehicle state information, a number of detected vehicles, the relative kinematic property and the reliability of the relative kinematic property of each detected vehicle, determine a host vehicle impact consequence level and an impact consequence level reliability measure indicative of a reliability of the determined host vehicle impact consequence level. On the basis of the host vehicle impact consequence level and the impact consequence level reliability measure, the system is further configured to determine whether the vehicle safety assist system should issue a warning signal and/or an autonomous braking signal.

A bicycle motor control system, configured to control a drive motor that is provided on a bicycle, comprises a controller configured to control a drive motor that is configured to selectively output driving force in accordance with a manual drive force, and cause the drive motor to stop when a detected manual drive force, sensed by a manual drive force sensor, falls below a predetermined force threshold value, which is set in accordance with a crank angle of a crankshaft.
