摘要:
The invention relates to a driver assistance system for displaying an image of the surroundings and to a corresponding method. A plurality of cameras captures images of the surroundings, and said images are combined in a data processing unit to form an image of the surroundings of the vehicle. An associated region of interest (ROI) is processed adaptively, e.g. by highlighting, for at least one object contained in the image of the surroundings.

The present disclosure relates to an apparatus (1) for estimation of a vehicle state. The apparatus (1) includes a controller (21) configured to determine a first estimation of the vehicle state in dependence on at least one first vehicle dynamics parameter. A filter coefficient (FC) is calculated based on a first vehicle operating parameter. An operating frequency of a first signal filter (35) is set in dependence on the determined filter coefficient (FC) and the first estimation is filtered to generate a first filtered estimation of the vehicle state. The present disclosure also relates to a vehicle; and to a method of estimating a vehicle state.

A method for determining road bank angle in a vehicle inlcludes a lateral acceleration sensor (22) that generates a lateral acceleration signal. A yaw rate sensor (18) generates a yaw rate signal. A roll rate sensor (24) generates a yaw rate signal. A controller (14) coupled to the sensors calculates a first roll angle signal in response to the roll rate signal and calculates a second roll angle signal corresponding to a suspension reference roll angle in response to the lateral acceleration signal. The controller calculates a bank angle signal in response to the lateral acceleration signal, the yaw rate signal, the steering wheel signal and the speed signal. The controller sums the first roll angle signal, the second roll angle signal and the bank angle signal to obtain a final roll angle estimate.
摘要:
A method and an apparatus for controlling an engine clutch are provided. The method includes determining whether an engine start condition is satisfied when an engine is stopped and performing an engine cranking operation by operating a hybrid starter & generator (HSG) when the engine start condition is satisfied. Whether an engine speed is greater than or equal to a first reference speed is determined to thus reduce an HSG torque. Then, whether the engine speed is greater than or equal to a second reference speed is determined to thus calculate a target speed of the engine. A speed control of the engine is performed using the target speed of the engine while determining whether an engine clutch engagement condition is satisfied. An engine clutch is engaged when the engine clutch engagement condition is satisfied.
