example 1

[0077] On the road segment 10 ahead of the vehicle 5, there is a low degree of congestion and a speed limit of 70 km / h. This situation is figure 1 shown in .

[0078] The road condition information acquired by the road information device 11 indicates an average speed of 70 km / h. Since the average speed is very close to the speed limit, the uncertainty estimate is low. Therefore, a minimum notification time of 1 minute may apply and handover notifications are provided 1.2 kilometers before the upcoming road segment 13 .

example 2

[0080] On the road segment 10 ahead of the vehicle 5, there is a high degree of congestion and a speed limit of 70 km / h. This situation is figure 2 shown in .

[0081] The road condition information acquired by the road information device 11 indicates an average speed of 8 km / h. If the uncertainty is estimated to be low, and if a minimum notification time is to be applied, a handover notification will be provided only 130 meters from the upcoming road segment 13 . However, since the switching device 1 is configured according to the embodiments herein, the uncertainty estimate will be high and the handover notification is provided 400 meters before the upcoming road segment 13 corresponding to 3 minutes before arriving at the upcoming road segment 13 .

[0082] Figures 3a-3d Each shows figure 1 The display unit 17 of the output unit 7 of the switching notification device 1 is shown in . exist Figure 3a with 3b In the embodiment shown in , the output unit 7 is configur...

Abstract

A handover notification arrangement is configured to provide a handover notification in a driver environment of a vehicle having autonomous driving capabilities. The handover notification arrangement includes a road information arrangement configured to acquire road information representative of an upcoming road section at which the autonomous driving is likely to become at least partially disabled. The handover notification arrangement further includes a processing unit configured to calculate an estimated time available for autonomous driving and configured to calculate an uncertainty estimate of the estimated time available for autonomous driving. The handover notification arrangement is configured to cause the output unit to provide the handover notification such that the handover notification is provided earlier in cases of high uncertainty estimates than in cases of low uncertainty estimates. The present disclosure also describes a vehicle and a method of providing a handover notification.

Description

technical field [0001] The present invention relates to a handover notification device configured to provide a handover notification in a driver's environment of a vehicle with autonomous driving capability, a vehicle, and a method of providing a handover notification in a driver's environment of a vehicle. Background technique [0002] Vehicles, especially cars or trucks used in road traffic, are increasingly equipped with driver assistance systems which allow the vehicle to be driven automatically in road traffic, which is often referred to as autonomous driving. This is achieved through the use of remote sensors arranged to acquire information about the vehicle's surroundings to allow steering control and / or speed control based thereon. During autonomous driving, the vehicle's occupants can be at least partially engaged in other activities. However, there are no autonomous vehicle controls available today that are fully capable of performing autonomous driving in all sit...
