A method for preventing a collision of a vehicle involves continuously detecting an operation of a brake pedal of the vehicle and concluding a risk of collision if the brake pedal is operated quickly. A position and a movement of objects in the vehicle surroundings relative to the vehicle are detected and evaluated regarding the risk of collision. When a risk of collision has been detected, an evasion maneuver of the vehicle is automatically carried out, if the evaluation of the risk of collision reveals that a collision can be prevented by an evasion maneuver but not by a braking manoeuvre.

The invention relates to a method for displaying a perspective image and to a display device for at least one passenger of a motor vehicle. The air of the vehicle is to guarantee by simple means a high road safety that is substantially independent of the knowledge and skills of the driver. To this end, a method for displaying a perspective image (B) with one image element (A toH) for at least one passenger of a motor vehicle is provided, said image (B) representing the view of the passenger. According to the inventive method, the image element (A toH) is changed in at least one size depending on the forward travel way (F), on at least one operational parameter of the motor vehicle and/or on at least one parameter of an object () identified in the range of the travel way (F).

The invention concerns a system for assisting an operator of a technical appliance, with a image display device (), of which the image is in the normal field of vision of the operator, for display of operationally relevant information in the form of images or symbols (). According to the invention, a respective image or symbol is displayed at least once for a brief period of time, of which the duration is below the threshold of conscious recognition and above the threshold of subconscious recognition of the operator.

An apparatus for determining the alertness of a person, especially a vehicle or machine operator, comprises an image pickup system for recording images of the area of at least one eye of the person, and an image evaluating system which evaluates the images detected by the image pickup system and contains means for detecting the shutting of an eye. The image evaluating system has means for determining pupil size and an evaluating apparatus which determines the alertness according to the eye closing state information obtained by the closed-eye detection means, and according to the pupil size information obtained by the pupil size determining means, with classification into one of at least three stages. The apparatus is used, for example, for determining the alertness of drivers of motor vehicles.
