Embodiment Construction

[0044] In summary, the embodiments herein relate to a method for determining a safe vehicle trajectory for a vehicle 1 equipped with sensors 2 for monitoring the surrounding environment, taking into account sensing constraints, so that the vehicle 1 can Driving with precautions, which are measures taken in advance to prevent dangerous, unpleasant or troublesome things from happening. Thus, a safe trajectory of the vehicle 1 as used herein means a trajectory that allows a relatively safe and / or comfortable ride for the occupants of the vehicle 1 .

[0045] Examples of sensors 2 include, but are not limited to, radio detection and ranging (radar) sensors, light detection and ranging (lidar) sensors, light amplification by radiation (laser) sensors, acoustic navigation and ranging (sonar) sensors ( One or more of, for example, ultrasound), infrared (IR) sensors, image sensors (such as cameras), vehicle location devices (such as global positioning systems), and any combination the...

Abstract

The present disclosure relates to a method and a device for determining a safe vehicle trajectory for a vehicle (1) equipped with a sensor (2) for monitoring the surrounding environment, taking into account sensing constraints, and a vehicle comprising such a device (1). The method comprises the following steps: detecting observable obstacles (3); detecting unobservable areas (4); adding virtual obstacles (5) in unobservable areas (4); making each observable Obstacles (3) and each virtual obstacle (5) are associated with one or more hypothetical events and each combination of obstacles (3, 5) and events is assigned a probability of occurrence; and based on the observable Obstacles (3) and virtual obstacles (5) as well as the occurrence probabilities of each combination of obstacles (3, 5) and events determine the trajectory of the safe vehicle (1).

Description

technical field [0001] Embodiments herein relate to a method and apparatus for determining a safe vehicle trajectory for a vehicle equipped with sensors for monitoring the surrounding environment, taking into account sensing constraints, and to a vehicle comprising such an apparatus. Background technique [0002] Motor vehicles are increasingly equipped with sensors that monitor the surrounding environment. This sensor information can be used to more or less automatically control the future trajectory of the vehicle. The automation can vary from a fully autonomous vehicle to a driver-controlled vehicle where the sensor information is used only to inform the driver. At all levels of automation, safe driving is required, which means in this case designing and implementing a vehicle trajectory with an acceptably low degree of risk. [0003] Where an automation function is responsible for a specific drive task, the automation system must be able to operate with a sufficiently ...
