Adaptive Emergency Braking for Motorcycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems in motor vehicles, such as distance control and emergency braking systems, often conflict between ensuring driving safety and providing driving pleasure, particularly in two-wheelers or motorcycles, as they intervene prematurely in sporty driving styles and fail to adapt to individual driver preferences.
Innovation Solution
The system allows drivers to select a driving mode that determines the emergency distance and deceleration rate, using machine learning to optimize emergency braking based on recognized driver profiles and vehicle dynamics, enabling adaptive assistance that prioritizes either safety or sportiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency braking system is activated at a fixed emergency distance threshold, then collision prevention is ensured, but driving pleasure is reduced due to premature interventions in sporty driving styles
Solution Approach 1:
The patent applies dynamics by making the emergency distance threshold adaptive rather than fixed. The system dynamically adjusts the emergency distance based on the recognized driving style (sporty or safe), allowing the threshold to change according to driver behavior patterns. This resolves the contradiction by enabling the system to maintain reliable collision prevention while adapting to different driving preferences, thereby preserving driving pleasure in sporty modes.
Solution Approach 2:
The patent changes the parameter of emergency distance threshold based on driving style recognition. When a sporty driving style is detected, the system increases the emergency distance threshold, allowing the vehicle to approach closer to the vehicle ahead before triggering emergency braking. This parameter adjustment resolves the contradiction by preventing premature interventions that would otherwise reduce driving pleasure while maintaining safety.
2Device complexity
If the emergency braking system uses a fixed deceleration rate, then system simplicity is maintained, but adaptability to different driving styles is reduced
Solution Approach 1:
The patent applies dynamics by making the deceleration rate adaptive based on driving style. The system recognizes whether the driver exhibits sporty or safe driving patterns and dynamically adjusts the deceleration rate accordingly. This allows the braking system to be more gentle for safe drivers and more aggressive for sporty drivers, enhancing adaptability without requiring complete system redesign.
Solution Approach 2:
The patent changes the deceleration rate parameter based on recognized driving style. The control unit adjusts this critical braking parameter dynamically, allowing the same physical braking system to deliver different braking characteristics suitable for different driving preferences. This resolves the contradiction by maintaining system simplicity in hardware while achieving adaptability through software-based parameter adjustment.
3Adaptability or versatility
If machine learning is used to recognize driver profiles, then adaptability to individual driving styles is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical or hardware-based adaptation systems with software-based machine learning algorithms. The driving style recognition is achieved through computational analysis of driving patterns rather than physical sensors or mechanical adjustments. This substitution reduces the type of complexity involved, trading hardware complexity for software intelligence, which can be updated and adapted more easily.
Solution Approach 2:
The system performs self-learning and self-adjustment by automatically recognizing driving styles from observed driving patterns. The machine learning model continuously adapts to the individual driver's preferences without requiring manual configuration or complex external calibration systems. This self-service capability reduces the need for additional complex setup and adjustment mechanisms.

AI summary
The invention relates to a method for operating a motor vehicle (1), wherein the speed of the motor vehicle (1) is set by a distance control system (7) depending on a target distance (Esoll) of the motor vehicle (1) to a road user (9) directly ahead, wherein, in order to maintain the predetermined target distance (Esoll), the speed is reduced by a braking process carried out by the distance control system (7) if the target distance (Esoll) is undershot, and wherein, in order to maintain a predetermined emergency distance (Enot) to the road user (9) ahead, the speed is reduced by an emergency braking process by an emergency braking system (11), wherein the emergency braking process causes a higher deceleration (-ȧ1/-ȧ2) of the motor vehicle (1) than the braking process.It is intended that the emergency distance (Enot) will be predetermined depending on a driving mode selectable by the driver of the motor vehicle (1).
