Automatic Parking Control with Mode-Based Vehicle Behavior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic parking systems do not consider the behavior of a vehicle during the execution of parking, leading to inadequate adaptation to different situations.
Innovation Solution
A vehicle control device that includes an environment recognition unit, a parking route generation unit, and a travel control unit, allowing the vehicle to adjust its behavior based on whether a first or second parking command signal is input, thereby enabling adaptive automatic parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed automatic parking behavior is used, then the system is simple to control, but it cannot adapt to different situations (passenger presence, remote control, etc.)
Solution Approach 1:
The patent implements dynamic behavior adjustment by switching between different operation modes (typical control setting and remote control setting) based on the input signal source. The travel control unit dynamically modifies vehicle behavior parameters such as steering speed, vehicle speed, and acceleration/deceleration rates according to whether the command comes from an in-vehicle button or a remote controller, allowing the system to adapt to different situations without increasing hardware complexity
Solution Approach 2:
The patent changes control parameters based on the operation mode. When a remote control signal is detected, the system adjusts parameters including steering speed (increased), vehicle speed (increased), and acceleration/deceleration rates (increased) compared to typical control mode. This parameter adjustment allows the vehicle to perform faster and more efficient parking when remotely controlled, while maintaining safer, more controlled behavior when a passenger is present
2Productivity
If the vehicle travels fast during automatic parking, then parking efficiency is improved, but safety is reduced when a passenger is present
Solution Approach 1:
The patent implements different speed parameters for different operation modes. In remote control mode, the vehicle speed is increased to improve parking efficiency when no passenger is present. In typical control mode (passenger present), the vehicle speed is reduced to ensure safety and passenger comfort. The travel control unit automatically selects appropriate speed parameters based on the detected signal source
3Reliability
If the vehicle travels slowly during automatic parking, then safety is improved when a passenger is present, but parking efficiency is reduced
Solution Approach 1:
The patent implements different speed parameters for different operation modes. In remote control mode, the vehicle speed is increased to improve parking efficiency when no passenger is present. In typical control mode (passenger present), the vehicle speed is reduced to ensure safety and passenger comfort. The travel control unit automatically selects appropriate speed parameters based on the detected signal source
Data Source
AI summary
This vehicle control device is provided with: an environment recognition unit for recognizing the surrounding environment of a vehicle; a parking route generation unit for generating a travel route to a parking position which is determined on the basis of the recognized surrounding environment; a signal input unit to which a parking command signal is input; and a travel control unit for causing the vehicle to travel along the travel route to the parking position on the basis of the input parking command signal. The vehicle control device drives the vehicle to travel to the parking position for automatic parking while behaving differently depending on whether the parking command signal input to the signal input unit is a first parking command signal or a second parking command signal.
