Parking Assist Engine Control Based on Parking Space Volume

The maximum permissible period for drive unit operation is made dynamic rather than static. The control device calculates this period based on real-time sensor data about the parking space volume, adjusting the shutdown timing to match the actual hazardous conditions. In large outdoor spaces, the drive unit can run longer, while in small enclosed spaces, it shuts down sooner, optimizing both safety and convenience for each situation.

The system changes the parameter of operation duration based on the detected parking space characteristics. By measuring the volume of the parking space using sensor data, the control device adapts the maximum permissible operation period accordingly. This parameter adaptation resolves the contradiction by allowing longer operation in safe environments while maintaining short operation periods in hazardous environments.

The system performs self-measurement of the parking space volume using its own sensor devices rather than relying on predefined standard volumes. The sensor system automatically detects the actual space characteristics, and the control device calculates the appropriate operation period based on this self-acquired data. This eliminates the need for user input while providing accurate, situation-specific timing.

The patent replaces the mechanical assumption of standard volumes with an optical/electronic measurement system. Instead of using fixed predefined values, the system uses sensor devices to optically or electronically detect the actual parking space dimensions and calculates the volume, thereby substituting a dynamic measurement approach for a static assumption approach.
