摘要:
A method and a device for ascertaining the imminence of an unavoidable collision of a vehicle with an object, all locations within a determinable prediction time interval being predetermined as a function of the maximum possible longitudinal acceleration and lateral acceleration of the vehicle and of the at least one object. The imminence of an unavoidable collision between the vehicle and the object may be recognized, also taking into account the extension of the vehicle and of the at least one object.
摘要:
In a method and a device for predicting movement trajectories of a vehicle to prevent or reduce the consequences of an imminent collision, in which for predicting the movement trajectories, only those trajectories are considered for which, because of a combination of steering intervention and braking intervention, the forces occurring at the wheels of the vehicle are within the range corresponding to the maximum force transferable from the wheel to the road. Particularly for systems which provide an automatic braking and/or steering intervention for avoiding a collision or reducing the severity of a crash with another object, an automatic braking and/or steering intervention is carried out as a function of the pre-calculated movement trajectories.
摘要:
A method and a device for controlling deceleration devices of a vehicle during a braking operation, e.g., a vehicle which is equipped with a sensor for adaptive cruise control. During the braking operation, risk dimensions are determined on the basis of driving dynamics models, which are individualized by signals of the surrounding-field sensor system. A first risk dimension is precalculated for the case of continued deceleration and a second risk dimension is precalculated for the case of unbraked further movement of the vehicle. Through the comparison of the two risk dimensions, it is decided whether the automatic vehicle deceleration is to be maintained or whether the braking is to be canceled before the vehicle is brought to a standstill.
摘要:
A method and a device for automatically triggering a deceleration of a vehicle so as to prevent a collision with another object. Objects in the range of the vehicle's course being detected using signals of an apparatus for sending and receiving radar signals or lidar signals, or of an apparatus for receiving video signals. An endangerment potential is determined as a function of the objects detected, and when a predefined endangerment potential theshold value, which may be less than the triggering threshold value for the deceleration, is exceeded, the deceleration means of the vehicle are reset to a state in preparation for braking. Furthermore, additional vehicle functions may be carried out when the endangerment potential threshold value is exceeded, whereby passenger safety in this travel situation is enhanced.
摘要:
A method and a device for automatic triggering of deceleration of a vehicle for preventing a collision, which is accomplished by the fact that a variable, which represents a probability of collision with another vehicle, must exceed a predefinable threshold value, and the threshold value is variable as a function of the driver's response, the current driving situation, or the ambient situation. To determine the change in the threshold value, signals from a steering angle sensor, a brake pedal sensor, an accelerator pedal sensor, a device for determining the speed of the vehicle, a device for determining the uphill or downhill slope of the road, a device for determining the vehicle yaw rate, a device for determining the vehicle float angle or a device for detecting stationary and moving objects in the vicinity of the vehicle, in particular in the area in front of the vehicle, are analyzed.
摘要:
A method and a device for triggering and implementing a deceleration of a vehicle to avoid a collision, in which, using a device for adaptive cruise control, objects in the sensor detection range are detected and measured variables are determined for each detected object. The detected objects are assigned to various object classes on the basis of the determined, associated measured variables, and the movement trajectories of the objects are predicted on the basis of the assignment of the detected objects to the particular class. Furthermore, a collision risk and an injury risk are determined from these predicted movement trajectories of the objects and the associated, detected object classes. In the event of the existence of preselected combinations of collision risks and injury risks, the deceleration devices of the vehicle are activated as a function of the degree of the collision risk.

摘要:
A method and a device for controlling automatic emergency braking of a motor vehicle to reduce the severity of a collision of a vehicle with an object, the position and/or speed of the object with respect to the host vehicle being determined via an object detection device, and this information being sent to a collision detection device which ascertains whether a collision with an object is imminent and, on detecting a collision, triggers emergency braking and ascertains a collision instant, emergency braking being terminated after the period of time until the determined collision instant has elapsed.

摘要:
A device for initiating and implementing a sudden vehicle deceleration, especially for emergency braking situations, the deceleration being initiated by the explosion of at least one propelling charge or explosive charge that acts on at least one component of the deceleration devices. Due to the explosion of the propelling charge or explosive charge, a piston is moved that applies pressure to the brake fluid, or an arrester is destroyed so that the stored energy of an energy-storing apparatus can be released. This device is triggered automatically with the aid of a surrounding-field sensor system when an unavoidable collision is detected based upon the objects in the surroundings of the vehicle and their movement.
