Valet Parking Activation via Proximity Detection and Keyless Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valet parking systems for motor vehicles are complex and inconvenient, requiring users to carry multiple keys or remote control devices to limit access to certain vehicle functions, particularly the trunk.
Innovation Solution
A method and device for activating and deactivating a valet parking function using a simple control element, such as a button or softkey, with authorization via input/output devices, allowing users to block and unblock lockable areas, including the trunk, through code input or biometric authentication, integrated into the vehicle's infotainment system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional valet parking systems use separate keys or remote control devices to limit access, then access control security is improved, but device complexity and user convenience deteriorate
Solution Approach 1:
The patent merges the valet parking activation function into the existing keyless entry system by utilizing the proximity detection capability already present in the vehicle. The control unit detects when a second keyless entry device (valet device) is in proximity to the vehicle and automatically activates the valet parking mode, eliminating the need for separate physical keys or complex remote control systems while maintaining security.
Solution Approach 2:
The patent makes the keyless entry device multi-functional by enabling it to serve both as a normal access key and as a valet parking activation device. The same type of device (keyless entry device with proximity detection) performs multiple functions: normal vehicle access, valet mode activation, and the system automatically manages trunk access restrictions without requiring additional specialized devices.
2Reliability
If conventional systems require carrying multiple keys or devices, then access control security is improved, but ease of operation deteriorates
Solution Approach 1:
The system combines multiple functions into a single keyless entry device type. Users carry only their normal keyless entry device, and the system automatically distinguishes between personal use and valet activation based on proximity detection and control unit logic, eliminating the need to carry separate valet keys or remote devices.
Solution Approach 2:
The system provides self-service functionality where the control unit automatically detects the presence of the second keyless entry device and autonomously activates the valet parking mode without requiring manual intervention, button pressing, or complex user actions. The trunk release function automatically becomes restricted, providing convenient automatic security management.
3Reliability
If valet parking function is activated with key switch, then access control is improved, but ease of operation deteriorates due to complex activation procedure
Solution Approach 1:
The control unit automatically performs the activation function by detecting when the second keyless entry device is in proximity to the vehicle. The system self-activates the valet parking mode without requiring the user to manually operate a key switch or perform any complex activation sequence, making the process as convenient as simply approaching the vehicle with the valet device.
Solution Approach 2:
The patent replaces the mechanical key switch system with an electronic proximity detection system. Instead of requiring physical manipulation of a key switch, the control unit uses electronic sensors to detect the presence of the keyless entry device and automatically activates the valet function, substituting mechanical operation with electronic automation.

AI summary
A method and device for activating and deactivating a valet parking function for a motor vehicle is provided. An activated valet parking function prevents access to one or more lockable areas in the motor vehicle. The method including the steps of checking whether a freely operable control element has been actuated. If the actuation of a control element has been detected, the valet parking function is activated to prevent exclusively the access to the lockable area in the motor vehicle, particularly to a trunk.
