Device and method for navigating and/or guiding the path of a vehicle, and vehicle

A vehicle, comprising:

• a device including;
• at least one first sensor including an inertial navigation which is designed and arranged to detect at least one first body part, including an absolute position and/or position and/or rotation and/or translation, of a passenger of the vehicle and to output first sensor signals;
• at least one second sensor including an image-based sensor which is designed and arranged to detect at least the first body part of the passenger and/or their features, including their absolute position and/or position and/or rotation and/or translation, and to output second sensor signals;
• and
• a control unit designed to;
• (a) receive the first and second sensor signals;
• (b) determine first control signals for controlling the vehicle based at least on the first sensor signals;
• (c) determine whether the first control signals meet at least first reliability criteria based at least on the second sensor signals;
• and
• (d) adopt a safety mode if the control unit determines that the first control signals do not meet at least the first reliability criteria;
• and one or more vehicle actuators including controllable motors, arranged to drive the vehicle and designed to receive and process the control signals of the device;
• wherein the first body part is the passenger's head and
• the control unit determines basic data on the basis of geometric dimensions and/or size ratios and/or features of the face and/or gestures detected by at least the second sensor;
• and
• the first reliability criteria are determined using the basic data.

A method for controlling a device for navigating and/or guiding the path and/or stabilizing a vehicle comprising:

• a) receiving at least first sensor signals comprising inertial navigation-based sensor signals, which describe at least the passenger's head, including its absolute position and/or position and/or rotation and/or translation, of a passenger of the vehicle;
• and
• b) receiving second sensor signals comprising an image-based front sensor, which is designed and arranged to describe at least the first body part or its characterizing features, including their absolute position and/or position and/or rotation and/or translation, of the passenger of the vehicle;
• c) determining basic data on the basis of geometric dimensions and/or size ratios and/or features of the face and/or gestures detected by at least the second sensor;
• d) determining first control signals for controlling the vehicle based at least on the first sensor signals;
• e) determining, via a control unit, whether the first control signals meet at least first reliability criteria based on at least the second sensor signals;
• and
• f) adopting a safety mode when the control unit determines that the control signals do not meet at least the first reliability criteria;
• wherein the first reliability criteria are determined using the basic data.
