Embodiment Construction

[0021] In a first step, the vehicle state of the first vehicle is ascertained (2) by the control unit of the first vehicle.

[0022] Depending on the vehicle state determined in (2) and the speed of the first vehicle, a range with a minimum distance M is defined. (4) An existing vehicle, in particular a second vehicle, is ascertained within a defined range.

[0023] Next, the first vehicle transmits within a minimum distance M data concerning its vehicle state (6). The ascertained data about its vehicle state ( 6 ) can be sensed or received by all vehicles within the minimum distance M. In particular, vehicle data for planning prudent driving behavior can be sent as a warning or vehicle data for planning a speed adaptation and / or trajectory adaptation into the minimum distance M. In this case the second vehicle can respond with an acknowledgment. For this purpose, the second vehicle can, for example, transmit its vehicle state to the first vehicle.

[0024] The vehicle sta...

Abstract

The invention relates to a method for triggering an evasive maneuver by means of at least one first autonomous or semiautonomous vehicle, wherein a vehicle state of the at least one first vehicle is determined by means of a control unit of the at least one first vehicle, vehicles within a minimum distance are determined by means of the at least one first vehicle, the determined data of the at least one first vehicle are transmitted within the minimum distance to determined vehicles by means of the at least one first vehicle in order to trigger an adjustment of a trajectory and / or a speed of the determined vehicles, and the at least one first vehicle is put into a safe state. The invention further relates to a system.

Description

technical field [0001] The invention relates to a method and a system for arranging an evasive maneuver by at least one first autonomous or partially autonomous vehicle. Background technique [0002] An autonomous vehicle can itself control its trajectory, speed and braking behavior by, for example, autonomously recognizing the course of the road, other road users or obstacles and calculating corresponding control commands in the vehicle and forwarding the control commands to actuators in the vehicle , thereby correctly affecting the direction of travel of the vehicle. Fully autonomous vehicles require no driver intervention. But both partially autonomous vehicles and autonomous vehicles can break down during driving. In the event of a failure, the autonomous or partially autonomous vehicle is transferred to a safe state. A safe state may include limiting speed or driving to a side street or nearby parking lot. [0003] Vehicle-to-X communication is now used in many vehi...
