Description

Technical Field

[0001] The present invention relates to a mobility scooter technology, and more specifically, to an intelligent parking assistance system for a mobility scooter and a control method thereof. Background Art

[0002] With the aging of society, more and more elderly people are starting to use mobility scooters to improve the convenience of daily travel. However, while mobility scooters provide convenience, they also bring new problems. Especially for the elderly, the use of mobility scooters is often accompanied by the trouble of parking difficulties.

[0003] At present, many elderly people often face parking inconveniences when using mobility scooters in public places, residential areas or shopping malls. Most traditional parking lot designs do not take into account the parking needs of mobility scooters. Many parking areas lack sufficient space or dedicated parking spaces, which makes it difficult for the elderly to find a suitable place when parking. Especially in crowded areas, the parking of mobility scooters not only occupies public passages, but may also cause inconvenience and safety hazards to other pedestrians.

[0004] In addition, due to the limitations of their physical functions, the elderly need a longer time to complete the parking operation, which further increases the inconvenience. Mobility vehicles are usually large in size and relatively complicated to operate. Especially for some elderly people with limited mobility, inconvenient parking methods may increase their physical burden and even cause accidents.

[0005] Therefore, how to solve the parking problem of the elderly when using mobility scooters and provide a more convenient and safe parking solution has become a social need that needs to be urgently addressed. To this end, it is particularly important to develop an innovative design that can effectively solve the parking difficulties of mobility scooters while taking into account the physical needs of the elderly.

[0029] S11, initializing the sensor unit, the system will perform a self-check on the sensor unit to ensure that all sensors are working properly and are ready to monitor the vehicle's surroundings in real time;

[0030] S12, initializing the vehicle control unit, the system will load historical parking data, driver setting parameters and environmental thematic data as reference, and prepare to process data from the sensor unit;

[0031] S13, initializing the parking execution unit to ensure that the wheel control module, the steering control module and the intelligent brake control module are in a standby state and are ready to receive instructions from the vehicle control unit at any time;

[0032] S2. Check whether parking requirements are met: When the driver starts the intelligent parking assistance system, the system will first detect through the sensor unit to determine whether parking requirements are met. This step includes:

[0033] S21, detecting the size of the parking space, using an ultrasonic sensor or a laser radar to detect the length, width, and height of the parking space, and determining whether the parking space is large enough to accommodate the mobility vehicle;

[0034] S22, detecting obstacle information, detecting whether there are obstacles around the parking space, and whether there are vehicles, pedestrians or other objects that hinder parking;

[0035] S23, detecting the road conditions, using a camera or an environmental sensor to detect the road conditions in front of and around the parking space, to ensure that there are no potholes, debris, or other factors that may affect parking in the parking area;

[0036] S24, detecting the relative position of the vehicle, determining the distance and angle of the mobility scooter relative to the parking space, and ensuring that the current state meets the parking requirements;

[0037] When the system determines that the parking requirements are met, it goes to S3; otherwise, it goes to S4;

[0038] S3, start parking operation: When the system determines that the vehicle surrounding environment meets the parking requirements, the vehicle control unit transmits a control signal to the parking execution unit to start the parking operation, specifically including:

[0039] S31, starting the wheel control module, the vehicle control unit sends out a command, and the wheel control module accurately adjusts the wheel speed so that the vehicle gradually enters the parking space;
