Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deactivating remote automatic parking mode in vehicles are unreliable, relying solely on user intention and common sense, which can be dangerous in fully automated parking garages where the vehicle may escape automaton control.
Innovation Solution
A method using tire monitoring systems with wheel units equipped with accelerometers to measure radial acceleration, comparing these values with a threshold to detect vehicle movement in a parking garage and automatically deactivate the remote parking mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user-based deactivation methods (button press or phone instruction) are used, then the system remains simple and easy to operate, but the reliability is insufficient because it depends on user intention and common sense
Solution Approach 1:
The system uses the vehicle's own tire monitoring system and accelerometer data to automatically detect parking garage conditions and deactivate remote parking mode without requiring user intervention. The vehicle monitors itself through its existing sensors (wheel speed, acceleration, tire pressure) and autonomously determines when deactivation is necessary, eliminating dependency on user intention while maintaining operational simplicity.
Solution Approach 2:
The system continuously monitors vehicle parameters (wheel speed, acceleration values, tire pressure) and uses this feedback to detect when the vehicle is in a parking garage. Based on this feedback loop, the system automatically deactivates remote parking mode when conditions indicate a parking garage environment, improving reliability through continuous monitoring and automatic response.
2Ease of operation
If remote automatic parking mode is activated in fully automated parking garages, then the user can exit the vehicle, but the vehicle may escape automaton control and cause damage
Solution Approach 1:
The system proactively detects parking garage conditions using accelerometer data and wheel speed information before the remote parking mode could cause harm. By identifying the parking garage environment in advance through monitoring vertical acceleration patterns and wheel behavior, the system deactivates remote parking mode beforehand, preventing potential escape from automaton control and avoiding damage.
Solution Approach 2:
The system performs preliminary detection of parking garage conditions by analyzing acceleration data and wheel parameters before allowing remote parking operation. This preliminary assessment ensures that remote parking mode is deactivated in advance when automaton-controlled parking is detected, preventing harmful situations before they can occur.

AI summary
A method for deactivating a remote automatic parking mode of a vehicle in a parking garage. The vehicle being equipped with a tire monitoring system, including wheel units mounted in each wheel of the vehicle and each being provided with an accelerometer measuring a radial component of an acceleration of the wheel and being dependent on a terrestrial gravitational field. The vehicle being provided with an automatic parking mode remotely controlled by portable equipment carried by a user. The method includes, if the conditions for activating the measurements of the wheel units are verified: each wheel unit measuring acceleration values over time; comparing said values with a threshold value, for each wheel unit; if the acceleration values of at least two wheel units exceed said threshold value, then: detecting any movement of said vehicle in a parking garage; and deactivating the remote automatic parking mode.
