Motor Vehicle Sensor Compensation for Tilt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing environment sensor systems in motor vehicles with tilting technology face a significant restriction in their field of vision when cornering, as the detected area in front of the vehicle inclines, limiting the effective detection range and illumination on the outside of the curve.
Innovation Solution
The integration of environment sensors rigidly connected to a movable element within a headlight module, controlled by an actuator system and position sensors, ensures that the sensors maintain a horizontal position relative to the road even when the vehicle tilts, compensating for inclination and other movements to maintain detection range and illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If environment sensors are installed in the front of the motor vehicle to detect objects or road users, then the driver assistance system can adjust speed to maintain safe distance, but the field of vision of the sensors is significantly restricted when the motor vehicle corners due to inclination
Solution Approach 1:
The patent applies the dynamics principle by making the sensor mounting position dynamic rather than fixed. The movable element carries the environment sensors and can be repositioned relative to the vehicle body, allowing the sensor field of vision to adapt dynamically during cornering maneuvers while maintaining reliable detection capabilities.
Solution Approach 2:
The patent segments the sensor system from the fixed vehicle structure by introducing a separate movable element. This segmentation allows the sensors to be independently positioned on the movable element, enabling the detection system to maintain its field of vision during cornering while the vehicle body inclines.
2Speed
If the motor vehicle uses tilting technology to corner analogously to single-track vehicles, then cornering performance is improved, but the area detected by environment sensors inclines and the detection range on the outside of the curve is limited
Solution Approach 1:
The patent maintains high-speed cornering performance through tilting technology while dynamically adjusting the sensor detection area. The movable element carrying the sensors can be repositioned to compensate for vehicle inclination, ensuring the detection area remains adequate and properly oriented during high-speed cornering maneuvers.
Solution Approach 2:
The patent applies preliminary anti-action by using the movable element to preemptively counteract the negative effect of vehicle inclination on sensor detection. Before the inclination severely limits the detection area, the movable element adjusts the sensor position to maintain adequate detection coverage on the outside of the curve.
3Ease of manufacture
If conventional environment sensor systems designed for non-tilting vehicles are used in motor vehicles with tilting technology, then development costs are reduced, but the sensors cannot maintain proper detection range and illumination during cornering
Solution Approach 1:
The patent achieves universality by making the sensor system adaptable to both tilting and non-tilting vehicle operations. The movable element provides multi-functionality by serving as both a mounting structure and an active compensation mechanism, allowing conventional sensors to maintain proper detection range during tilting while preserving compatibility with standard sensor designs.
Solution Approach 2:
The patent dynamically adjusts the sensor position using the movable element to maintain reliable detection range during tilting operations. This dynamic adjustment allows conventional environment sensor systems to be used in tilting vehicles without sacrificing detection reliability, as the movable element compensates for the inclination effects in real-time.

AI summary
The invention relates to a motor vehicle, which is a single-track motor vehicle or a multi-track motor vehicle having tilt technology and which comprises one or more environment sensors (10, 10'), which are installed in the front of the motor vehicle (100) and are designed to sense a region lying in front of the front of the motor vehicle (100). The motor vehicle according to the invention is characterized in that the one or more environment sensors (10, 10') are rigidly connected to a movable element (6), which can be moved by rotation and/or pivoting by means of an actuating system (2), wherein a control unit (4) for controlling the actuating system (2) and a position-sensing system (3) for sensing the position of the motor vehicle (100) in space are provided in the motor vehicle (100). The control unit (4) controls the actuating system (2) during travel of the motor vehicle (100) in accordance with the position of the motor vehicle (100) sensed by the position-sensing system (3) in such a way that, in the case of tilt of the motor vehicle (100) along a plane perpendicular to the longitudinal axis (x) of the motor vehicle, the movable element (6) is moved by means of the actuating system (2) in such a way that the position of each environment sensor (10, 10') with the tilt of the motor vehicle (100) is not rotated with respect to the longitudinal axis (x) of the motor vehicle (100) in comparison with the position of the environment sensor (10, 10') without tilt of the motor vehicle (100).
