Automated Vehicle Gate Passage Control via Target Following
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated driving systems fail to smoothly control vehicles when passing through gates, such as those at toll plazas, due to lack of consideration for gate passage scenarios.
Innovation Solution
A vehicle control system that selects a following target vehicle among nearby vehicles to mimic its passage through a gate, using a gate selector and passage controller to navigate the vehicle through the gate, while acquiring information on other vehicles' routes and gate types to ensure smooth passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving control is implemented using conventional route generation methods, then the system can perform automated driving along current traveling paths, but it cannot smoothly control vehicles when passing through gates such as toll plazas
Solution Approach 1:
The system performs preliminary actions by selecting a following target vehicle in advance before reaching the gate, and generates a route that follows the selected vehicle's trajectory through the gate. This advance preparation enables smooth gate passage control without requiring complex real-time decision-making at the gate itself.
Solution Approach 2:
The system copies the behavior and trajectory of a selected following target vehicle when passing through the gate. By mimicking the target vehicle's route and passage pattern, the automated driving system can navigate gates smoothly without needing to independently solve the complex gate passage control problem.
2Reliability
If the system selects a following target vehicle and follows its route through the gate, then smooth passage is achieved, but the system requires additional information acquisition and vehicle selection capabilities
Solution Approach 1:
The automated driving control unit performs multiple functions: it generates routes for automated driving, selects following target vehicles, acquires information about other vehicles and gates, and controls passage through gates. By consolidating these diverse functions into a single control unit, the system achieves smooth gate passage without significantly increasing overall system complexity.
Solution Approach 2:
The system uses existing automated driving components (route generation unit, vehicle detection capabilities) to serve the additional function of gate passage control. By leveraging existing self-service capabilities rather than adding completely new subsystems, the system maintains relatively simple architecture while achieving the desired functionality.
3Reliability
If the system follows a target vehicle through the gate, then gate passage is smoothed, but the system may need to cancel following control when the target vehicle becomes inappropriate
Solution Approach 1:
The system continuously monitors the state of the following target vehicle and the gate passage situation, and uses this feedback to determine when to cancel following control. When the target vehicle becomes inappropriate (e.g., stops, changes direction, or the gate type changes), the system detects this through feedback and adjusts its control strategy accordingly, ensuring appropriate following control is maintained only when beneficial.

AI summary
A vehicle control system includes a vehicle selector configured to select, from among other vehicles present near an own vehicle, another vehicle that the own vehicle is to follow when traveling in front of a gate as a following target vehicle, and a gate passage controller configured to cause the own vehicle to travel following the following target vehicle selected by the vehicle selector when passing through the gate.
