Autonomous Vehicle Power-On Timing for On-Time Parking Departure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic parking systems face challenges in ensuring smooth departure of autonomous vehicles from parking spaces to pickup areas due to the time required for departure preparation, such as charging backup power sources for brakes, which can cause delays.
Innovation Solution
An automatic parking system is configured with an on-control time setting unit that establishes a power-on state for the autonomous vehicle prior to the departure time, allowing for pre-departure preparation and determining this time based on the departure preparation required time to ensure timely and smooth departures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the autonomous vehicle waits until the departure time to start preparation, then the power consumption is reduced, but the departure is delayed due to insufficient preparation time
Solution Approach 1:
The system performs departure preparation in advance by setting the power switch timing to turn on the power before the actual departure time. This preliminary action allows the vehicle to complete necessary preparations (such as charging backup power source for brake) before departure, eliminating delays while managing power consumption through precise timing control
2Ease of operation
If the power is turned on earlier to complete preparation, then the departure smoothness is improved, but the power consumption increases
Solution Approach 1:
The system determines the optimal power switch timing based on the relationship between departure time and preparation time requirements. By calculating when power should be turned on to complete preparation exactly before departure, the system achieves smooth departure while avoiding unnecessary extended power-on periods that would waste energy
Solution Approach 2:
The system dynamically adjusts the power switch timing parameter based on varying preparation time requirements for different departure scenarios. By changing this temporal parameter optimally, the system balances departure smoothness with power consumption efficiency

AI summary
An automatic parking system configured to cause an autonomous vehicle to travel autonomously from a parking space to a pickup area based on a parking space departure time determined such that the autonomous vehicle arrives the pickup area at a scheduled pickup time that is predetermined. The automatic parking system includes an on-control time setting unit configured to set an on-control time at which a state of the autonomous vehicle is controlled to be a power-on state based on the parking space departure time, and a power-on control unit configured to control the state of the autonomous vehicle to be the power-on state based on the on-control time that is set. The on-control time setting unit is configured to set the on-control time such that the power-on state is established prior to the parking space departure time.
