An internal combustion engine for a motor vehicle includes a crankshaft, a camshaft, a cylinder, a piston movably disposed in the cylinder and coupled to the crankshaft for driving the crankshaft, a first gas exchange valve which is assigned to the cylinder, a first valve clearance compensation device, where via the first valve clearance compensation device the first gas exchange valve is displaceable between a first open position and a first closed position by a first cam of the camshaft, and a control unit. The control unit is configured to align the camshaft such that the first valve clearance compensation device is pressure-loaded in the idle state of the crankshaft by a plateau area assigned to the first cam to hold the first gas exchange valve in the first open position.

An internal combustion engine for a motor vehicle includes a combustion chamber with a gas exchange valve which is movable between an open position and a first closed position. The gas exchange valve is movable on its path from the open position in a direction of the first closed position into an intermediate position located between the open position and the first closed position and is holdable in the intermediate position at least during a part of a compression cycle of the combustion chamber following the open position of the gas exchange valve and is movable into a second closed position following the intermediate position. The part comprises more than a half of the compression cycle and less than a whole of the compression cycle. The gas exchange valve is an inlet valve via which the combustion chamber is supplyable at least with air.

A system, vehicle and method are provided that automatically activate and deactivate a driver assistance system. The automatic activation and deactivation depend on predefined criteria such as brake or gas pedal release, current vehicle velocity, and the presence of a lead vehicle.

Implicit activation and control of driver assistance systems

A method to control functions in a vehicle using gestures carried out in three-dimensional space. When it is determined that a first gesture carried out in three-dimensional space is detected by an image-based detection procedure, it is determined whether the first gesture is a gesture directed towards a virtual object superimposing a real environment around the vehicle. If it is determined that the first gesture has been detected, it is determined whether a second gesture carried out in three-dimensional space is detected by the image-based detection procedure. If so, it is determined whether the detected second gesture is a gesture allocated to a manipulation of the virtual object, and the virtual object is manipulated accordingly.
