Battery Swap Parking Torque Control for Reverse-Speed Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In manual battery swap parking, vehicles often experience uncontrollable speeds due to uneven driver skills, leading to collisions with battery charging and swap station infrastructure.
Innovation Solution
A battery swap parking control method that determines a parking speed limit threshold based on the vehicle's current position, calculates a torque limit value, and controls the driving torque to maintain safe parking speeds, preventing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual battery swap parking is used, then the vehicle can be parked at the battery charging and swap station, but the driver cannot well control the vehicle speed, leading to collision with the infrastructure
Solution Approach 1:
The patent replaces the purely mechanical manual speed control system with an electronic control system that automatically limits driving torque based on vehicle position. The control system detects vehicle position relative to the battery charging and swap station infrastructure and automatically adjusts torque limits, substituting driver manual control with an automated electronic control mechanism to prevent collisions.
2Ease of operation
If automatic battery swap parking is used, then the battery swap experience is enhanced, but the automatic parking system may fail, requiring switch to manual parking
Solution Approach 1:
The patent changes the control parameter from full automatic operation to position-based torque limiting. When automatic parking fails and manual parking is initiated, the system doesn't return to pure manual control but instead applies automated torque limit parameters based on vehicle position, creating a hybrid control mode that maintains safety while allowing manual operation.
3Ease of operation
If driver manually parks the vehicle, then the vehicle can be positioned at the battery swap station, but uneven driving skills lead to unintended operations and potential accidents
Solution Approach 1:
The patent introduces an intermediary control system that sits between the driver's manual control inputs and the vehicle's drive system. The control system acts as a mediator by monitoring vehicle position and automatically limiting torque output, preventing the driver's unintended operations from causing harmful collisions while still allowing manual parking capability.

AI summary
The disclosure relates to the technical field of battery swapping, and in particular to a battery swap parking control method, a medium, an apparatus, and a vehicle. The disclosure aims to solve the problem in manual battery swap parking that a vehicle speed cannot be well controlled, leading to a collision with an infrastructure of a battery charging and swap station. To this end, the battery swap parking control method of the disclosure includes: obtaining a current position and a current speed of a vehicle when the vehicle is in a reverse gear; determining a parking speed limit threshold based on the current position; comparing the current speed with the parking speed limit threshold; and controlling a driving torque of the vehicle based on a comparison result. According to the control method of the disclosure, the current position of the vehicle in a parking process is obtained, and the driving torque of the vehicle is controlled based on the comparison between the parking speed limit threshold corresponding to the current position, and the current speed. In this way, a parking speed of the vehicle can be controlled in the parking process, thereby avoiding damage to the infrastructure of the battery charging and swap station due to an excessively fast speed, and improving the safety of a manual battery swap parking process.
