Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart parking assist systems require drivers to manually check surroundings and press buttons multiple times to select an exiting direction, leading to inconvenience and potential errors when exiting a parking lot, especially in tight spaces.
Innovation Solution
A smart parking assist system that uses forward, lateral, and rearward sensors to detect obstacles and calculate distances, determining the optimal exiting mode and adjusting the steering angle to assist the vehicle in exiting efficiently, thereby eliminating the need for manual button presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver manually checks surroundings and presses buttons multiple times to select an exiting direction, then the exiting operation can be performed, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The system enables self-service by allowing the vehicle to automatically detect obstacles, calculate distances, determine the optimal exiting direction, and execute the exiting maneuver without requiring the driver to manually check surroundings or press buttons multiple times. The vehicle's sensor system and control unit perform these functions autonomously based on environmental data.
Solution Approach 2:
The system performs preliminary actions by pre-calculating multiple potential exiting paths and evaluating them for safety and efficiency before the driver initiates exiting. The sensor system continuously monitors the environment and prepares exiting options in advance, so when the driver activates the function, the system can immediately execute the optimal pre-determined path.
2Reliability
If a driver manually checks surroundings to decide exiting direction, then the exiting can be initiated, but errors and time delays may occur
Solution Approach 1:
The system replaces the mechanical system of manual visual checking and button pressing with an automated sensor-based detection and control system. Sensors continuously monitor obstacles and distances, while a control unit processes this data to automatically determine the safest and most efficient exiting direction, eliminating human error and reaction time delays.
Solution Approach 2:
The system implements feedback by continuously monitoring obstacle positions and distances through sensors during the exiting process, and automatically adjusting the exiting path and steering commands based on real-time environmental data. This closed-loop control ensures accurate and safe exiting even in dynamic conditions.
3Adaptability or versatility
If sensors are installed only at the side of the vehicle for parking state detection, then the parking state can be recognized, but the exiting assistance is limited
Solution Approach 1:
The system achieves multi-functionality by using the existing side sensors for both parking state detection and exiting assistance, and by adding front and rear sensors that serve dual purposes for both parking and exiting operations. This universal approach allows a single sensor system to support multiple parking and exiting scenarios without requiring separate dedicated systems for each function.

AI summary
Disclosed herein is a smart parking assist system may include: a forward object sensing unit, a lateral object sensing unit, a rearward object sensing unit, an object distance calculation unit configured to calculate distance from a lateral object and a rearward object, a parking control unit, and a steering angle adjusting unit. The parking control unit recognizes left parallel exiting, right parallel exiting or perpendicular exiting based on a distance from a forward object sensed through the forward object sensing unit, a distance from a rearward object sensed through the rearward object sensing unit, and a distance from a lateral object sensed through the lateral object sensing unit, and controls steering angle adjustment such that the vehicle moves through the recognized left parallel exiting, right parallel exiting or perpendicular exiting. The steering angle adjusting unit adjusts a steering angle according to steering control signal of the parking control unit.
