摘要:
A method and a device for operating a motor vehicle in an automated driving mode are proposed, in which a standard trajectory is determined which implements vehicle control in accordance with the target setting process predefined by the driver and the instantaneous situation in the vehicle surroundings, and a safety trajectory is determined which, in the case of an emergency, implements safe stopping of the vehicle as a function of the instantaneous situation in the vehicle surroundings, in which the standard trajectory is also fed to a first control device, by which the signals can be passed on to actuator devices of the vehicle in order to control the vehicle on the basis of the standard trajectory, and the safety trajectory is fed to a second control device, by which signals can be passed on to actuator devices of the vehicle in order to control the vehicle on the basis of the safety trajectory, wherein in the standard operating mode the actuator devices for controlling the vehicle are actuated by the first control device, and in the safety situation, when the automated driving mode cannot be ensured, the actuator devices are actuated by the second control device in order to stop the vehicle without danger.

There are provided a driving support apparatus and a driving support method in which the reliability can be improved. In the driving support apparatus 1, in a traveling direction of the host vehicle and a direction crossing the traveling direction, an intersection where the host vehicle and the moving object cross is predicted; a virtual TTC that it takes for the host vehicle to arrive at the intersection and a virtual TTV that it takes for the moving object to arrive at the intersection when the moving object moves in the direction crossing the traveling direction at a virtual speed which is set virtually, are respectively acquired; and the driving support in the host vehicle is implemented based on the relative relationship between the virtual TTC and the virtual TTV.

An object of the invention is to provide, in a vehicle driving assistance system that provides assistance to avoid a collision between a host vehicle and a three-dimensional object causing an obstruction, a technique for avoiding assistance in which the host vehicle is guided to a region where the presence of a three-dimensional object is unclear. To achieve this object, according to the invention, a grid map, by which an avoidance region in which a three-dimensional object exists, an unclear region in which the existence of a three-dimensional object is unclear, and a safe region in which no three-dimensional objects exist can be distinguished, is created. When the avoidance region exists on the advancement path of the host vehicle, a route that can avoid the avoidance region and passes through the unclear region for a distance not exceeding a threshold is specified, whereupon a steering angle is controlled to cause the host vehicle to travel along the specified route.

A vehicle (1), a vehicle system (2) and a method (100) for increasing at least one of safety and comfort during autonomous driving is provided. The vehicle system (2) comprises an autonomous drive arrangement (3) with a plurality of sensors (5), a vehicle control arrangement (8) and a positioning system (4).The vehicle system (2) is arranged to determine an estimated probability that at least one sensor (5) will become unavailable, or an estimated time/ distance ahead until at least one sensor (5) is determined to become unavailable. The vehicle system (2) is further arranged to activate at least one countermeasure based on at least one of the estimated probability, the estimated time and the estimated distance.

A collision mitigation apparatus includes an object detecting section for detecting a collision object present in front of an own vehicle on which the collision mitigation apparatus is mounted, a drive assisting section that performs drive assist for avoiding a collision between the collision object detected by the object detecting section and the own vehicle or mitigates damage to the own vehicle due to the collision, an operation state detecting section for detecting an operation state of the own vehicle, and a timing setting section for setting start timing to start the drive assist by the drive assisting section in accordance with the operation state detected by the operation state detecting section.
摘要:
The invention relates to a method (100) for avoiding or mitigating a collision of a vehicle (300) with an obstacle (302) in a lane (402) of the vehicle (300) if the obstacle (302) at least partially blocks a planned driving path of the vehicle (300). Said method (100) comprises a detection step (102) and an adaptation step (104). In the detection step (102), a position and/or trajectory of the obstacle (302) is detected. In the adaptation step (104), the driving path (316) is adapted using the position and/or trajectory in order to avoid or mitigate the collision.
