  • Digital Car Key Authorization with Time and Location Constraints: R&D Project Proposal

    Intelligent Vehicle R&D

    Digital Car Key Authorization with Time and Location Constraints: R&D Project Proposal

    A project proposal template for a digital car key authorization platform using time constraints, geofencing, dynamic risk assessment and secure key management.

    XSD Precision2026-07-07

    Project Overview

    Project nameDigital car key authorization method and system with time and location constraints
    DepartmentR&D Center / Intelligent Automotive Business Unit
    Project cycle2026-X to 2027-X
    Project levelStrategic / key / general project, subject to internal review
    Target outputAuthorization rule engine, geofence decision module, dynamic authorization module and security control module

    Industry Background

    Vehicle access control is moving from mechanical keys to digital key systems based on mobile devices and connected vehicle platforms. Mainstream solutions commonly use NFC, Bluetooth Low Energy (BLE), and Ultra Wide Band (UWB) for authentication.

    • Existing authorization is often too coarse-grained.
    • Permission management can be static and simple.
    • Dynamic risk control is often missing.
    • Shared mobility, fleet, rental and temporary driver scenarios require more flexible rules.

    Target Scenarios

    Family shared vehicleParents authorize children to use a vehicle only within a specified time period and region.
    Enterprise fleetEmployees can use vehicles only during approved working hours or routes.
    Vehicle rentalThe renter receives vehicle access only within the rental term.
    Designated driver serviceOne-time temporary digital key authorization expires automatically after use.

    Technical Objectives

    • Time constraints: fixed time, recurring time and dynamic time windows.
    • Spatial constraints: circular geofence, polygon geofence and multi-layer geofence.
    • Dynamic authorization: real-time permission adjustment, risk scoring and temporary authorization.
    • Data security: end-to-end encryption, dynamic key mechanism and anti-replay protection.

    R&D Work Packages

    Topic 1Time-space authorization model: time constraints, spatial constraints and combined authorization rules; output authorization rule engine.
    Topic 2Geofence control algorithm: GPS positioning, BLE-assisted positioning and UWB precise positioning; output geofence decision module.
    Topic 3Dynamic authorization decision engine: user identity management, permission calculation and risk scoring; output dynamic authorization module.
    Topic 4Digital key security mechanism: key management, identity authentication and data encryption; output security control module.

    Technical Route

    User AppDigital Key Management PlatformTime Constraint Engine / Location Constraint Engine / Risk Assessment Engine / Authorization Decision EngineVehicle T-BOXDoor Controller

    Innovation Points

    • Time-location joint authorization: validates both time and location conditions before access is granted.
    • Dynamic permission adjustment: adjusts permission according to user status, vehicle status and risk level.
    • Multi-level geofence control: unlock, start and re-authorization permissions can use different geofence policies.
    • One-time digital key mechanism: temporary authorization automatically expires after completion.

    IP Planning

    Invention patent 1Digital car key authorization method with time and location constraints.
    Invention patent 2Digital key control method based on multi-level geofence.
    Invention patent 3Dynamic risk-assessment digital key authorization system.
    Software copyrightDigital Key Authorization Management Platform V1.0.

    Advanced Patent Mining Directions

    1. Dynamic time-space authorization engineMove beyond static rules such as 08:00-18:00 and a fixed city boundary. Authorization conditions should change according to user identity, vehicle state, traffic state and risk level. Example rules include full access on normal workdays, no start after 23:00, secondary authentication in remote areas and no re-authorization when battery level is below 15%. Patent focus: digital key authorization decision method based on dynamic risk factors.
    2. Multi-layer geofence authorizationUpgrade from a single geofence to layered zones and permission matrices. Level 1 may allow unlock and start, level 2 may allow unlock but deny start, and level 3 may only allow vehicle viewing. Patent focus: vehicle access control method based on multi-layer geofence.
    3. Route-constrained digital keyMost systems restrict location, but fewer restrict a route. The system can authorize a route from a company location to a customer site; if the vehicle deviates, it can downgrade permission and send an alert. Patent focus: digital key authorization control method based on a preset driving trajectory.
    4. One-time digital keyA one-time key can be valid for a single use, expire after reaching a specified location, or expire after one vehicle start. It is suitable for valet parking, car washing, maintenance and logistics handover. Patent focus: time-space limited digital key generation method with a single-start feature.
    5. AI risk-scoring authorizationBuild user profiles, driving habits and historical location features, then calculate a real-time risk score. Low risk can be automatically authorized, medium risk can require phone confirmation, and high risk can block vehicle start. Patent focus: vehicle digital key dynamic authorization method based on a risk scoring model.
    6. Multi-user shared authorization chainSupport family and enterprise sharing with hierarchical delegation. For example, owner A authorizes spouse B and child C; B may re-authorize once, while C may not re-authorize. Patent focus: digital key management method supporting hierarchical re-authorization.
    7. Vehicle-state-linked authorizationCombine key permission with vehicle conditions such as abnormal battery temperature, maintenance mode, fault codes or low energy. The system can block start, limit speed or allow only maintenance personnel to start. Patent focus: digital key dynamic authorization method based on vehicle operating state.
    8. UWB precise distance authorizationUWB can support not only proximity judgment, but also position angle, movement direction and approach speed. For example, unlocking can be allowed only when the user approaches from the driver's side. Patent focus: vehicle key authorization method based on UWB spatial position features.
