Problems solved by technology

This can cause automatic deceleration or braking to be performed too late and can therefore be difficult
Thus, to ensure good long-range performance, more complex and thus often more expensive sensors may be relied upon, adding to system cost and complexity

Embodiment Construction

[0043] In general, the examples here relate to the figure 1 A safety device 1 for controlling the autonomous driving of a fully automated vehicle 2 is shown.

[0044] The safety device 1 for controlling the autonomous driving of a fully automated vehicle 2 includes one or more forward-looking detection systems 3 for detecting and ranging objects 4 on the future path of the vehicle 2 .

[0045]In some embodiments herein, the forward-looking detection system 3 includes one or more radio detection and ranging (RADAR, radar) sensors, light amplification by stimulated emission of radiation (LASER, laser) sensors, light Detection and ranging (LIDAR, lidar) sensors, ultrasonic sensors, infrared sensors, image sensors or any combination thereof.

[0046] The image sensor may be a video sensor, for example designed as a Charge Coupled Device (CCD) camera or a Complementary Metal Oxide Semiconductor (CMOS) camera.

[0047] The security device 1 also comprises a control unit 5 configur...

Abstract

Embodiments herein relate to a safety device (1) and a method for controlling the safe autonomous driving (1) of a fully automated vehicle (2). One or more forward looking detection systems (3) are provided for detecting objects (4) on the future path of the vehicle (2). The control unit (5) is configured to determine a detection confidence level with respect to said detection target (4). The control unit (5) is further operable to control the braking system (6) of the vehicle (2) to apply a predetermined limited amount of braking based on a low degree of confidence regarding the presence of the detected object (4) until obtaining information on the front Detect the presence or absence of an object (4) with high confidence. The control unit (5) is then also operable to apply full braking if a high degree of confidence is obtained regarding the presence of the forward detected object (4), and to interrupt if a high degree of confidence is obtained regarding the absence of the forward detected object (4) brake.

Description

technical field [0001] Embodiments herein relate to safety devices for controlling the autonomous driving of a fully automated vehicle. [0002] Embodiments herein relate to methods for controlling the autonomous driving of a fully automated vehicle. [0003] Yet another embodiment herein relates to a motor vehicle comprising safety equipment for controlling the autonomous driving of a fully automated vehicle. Background technique [0004] In a fully automated motor vehicle, the driver no longer performs the task of driving. This increases the demands placed on vehicle systems, especially vehicle sensing systems. The performance of most vehicle sensing systems relied upon today degrades as sensing distance increases. This presents a challenge because the sensors of the sensing system are required to detect all objects present on the vehicle's future path while minimizing the number of unreliable or false detections. [0005] Today's sensor systems have good object classi...
