Vehicle Driving Assistant Overtaking State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle driving assistants cause discomfort to drivers by unnecessarily intervening when they attempt to steer towards obstacles in the posterolateral direction, as these systems fail to differentiate between overtaking maneuvers and obstacle avoidance.
Innovation Solution
A vehicle driving assistant system that includes a side obstacle detector, an overtaking state detector, and a control suppressor, which determines if the vehicle is in an overtaking state and adjusts the obstacle access prevention control accordingly, thereby reducing driver discomfort by suppressing interventions during intended lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If obstacle access prevention control is implemented to prevent the vehicle from accessing obstacles in the posterolateral direction, then safety is improved, but driver comfort deteriorates due to unnecessary interventions during overtaking maneuvers
Solution Approach 1:
The system dynamically adjusts the obstacle access prevention control based on the detected driving state. When an overtaking state is detected, the control is suppressed or deactivated, allowing the driver to steer towards obstacles without unnecessary intervention. When not in overtaking mode, the control remains active to prevent accidental access to obstacles. This dynamic adaptation resolves the contradiction by making the system's behavior context-dependent.
Solution Approach 2:
The system changes the control parameter (obstacle access prevention control activation) based on the driving state parameter (overtaking state detection). By monitoring parameters such as vehicle speed, steering angle, and position relative to obstacles, the system determines whether to activate or suppress the prevention control, thereby balancing safety and driver comfort.
2Ease of operation
If the system suppresses obstacle access prevention control when overtaking state is detected, then driver comfort is improved, but the risk of accidental obstacle access increases
Solution Approach 1:
The system dynamically switches between control modes based on real-time detection of overtaking state. The transition between active control and suppressed control is governed by detected driving conditions, ensuring that safety measures are applied only when appropriate while maintaining driver comfort during legitimate overtaking maneuvers.
Solution Approach 2:
The system continuously monitors driving state parameters (vehicle speed, steering angle, obstacle position) and uses this feedback to determine whether to activate or suppress obstacle access prevention control. This closed-loop feedback mechanism ensures that control suppression occurs only when genuine overtaking is detected, maintaining safety while improving comfort.

AI summary
An overtaking state is detected which is at least one of a first state where an own vehicle (MM) is overtaking an obstacle (SM) in a posterolateral direction of the own vehicle (MM) and a second state where the own vehicle (MM) is estimated to overtake the obstacle (SM). In the implementation of an obstacle access prevention control for preventing the own vehicle (MM) from accessing the obstacle (SM) present in the posterolateral direction of the own vehicle (MM), when a determination that the overtaking state is established is made based on the detecting, the obstacle access prevention control with respect to the obstacle (SM) is suppressed compared with when the determination that the overtaking state is established is not made.
