Collision prevention system for vehicles
First Claim
1. A method for preventing a vehicle colliding with obstacles, distance values between the vehicle and obstacles in the surroundings being sensed and the driving space which is available being calculated from these distance values, values relating to the current movement (speed, direction of travel, deceleration etc.) of the vehicle being additionally sensed and the driving space which is required to continue the journey being calculated from these values in conjunction with values of the dimensions of each vehicle, a comparison between the existing driving space and required driving space being subsequently carried out, and measures for preventing collisions being initiated when the required driving space extends beyond the existing driving space, characterized in that the values of the dimensions of the veh Abt-Fulrad-StraBe 4icle are read out of a memory, which is configured in such a way that a plurality of different vehicle contours can be stored in it.

Abstract
The invention relates to a system for preventing collisions of an automobile with obstacles. Sensors mounted in the automobile detect the area surrounding the vehicle. The signals of said sensors are evaluated by a data processing device in order to calculate the available obstacle-free driving space. Other sensors additionally detect the position of all movable vehicle parts (e.g. a trailer) and the dynamic parameters of the current driving situation (e.g. speed, steering angle, etc.). Based on said data, the driving speed required during the following time intervals in order to continue driving is calculated in advance by the data processing device and compared with the actually available obstacle-free driving space that has been detected. Said comparison provides early forecast regarding a possible collision. The driver is warned of a possible collision danger by corresponding warning devices and can consequently react in time. In critical situations (e.g. high driving speed), direct interventions in the control of the vehicle by the data processing device can take place to assist the driver.
