A method for remote controlling an object with a remote-control unit is provided. At least a first surface S, S, Sis defined in a first coordinate system. At least a first function of the object is associated to the first surface S, S, S. A second coordinate system is defined at the position of the remote-control unit. A static pointing vectoris defined in the second coordinate system. It is then determined whether the pointing vector points towards the first surface S, S, S. If so, the object is enabled to selectively activate the first operation upon receipt of an activation command.

Remote control for automotive applications

Device for control of headlight range of a motor vehicle including a front axle transmitter ( ) and a rear axle transmitter ( ), which generate signals depending on a position of a vehicle chassis relative to a front axle and a rear axle of the vehicle, wherein the device further includes adjustment devices ( ), which can adjust the headlight range of the motor vehicle depending on these signals. The device further includes a speed transmitter ( ) and a terrain recognition unit ( ), with the terrain recognition unit ( ) being connected to the front axle transmitter ( ), the rear axle transmitter ( ), and the speed transmitter ( ). The terrain recognition unit can calculate and store a difference between the signals from the front axle transmitter ( ) and the rear axle transmitter ( ), subtract a previously calculated difference in the signals, divide the signal obtained by this subtraction by a signal corresponding to the speed of the vehicle, and compare the signal obtained by this division with a predetermined threshold value. The terrain recognition unit ( ) decides that a poor road surface is present when the threshold value is exceeded, and possibly deactivates control of the headlight range.
