The invention belongs to the technical field of auxiliary parking, and provides a parking stall release method and system considering the parking success rate and an intelligent parking method in order to improve the parking success rate. The minimum reserved safety distance capable of meeting the parking success rate set value is obtained through matching according to the incidence relation between the parking success rate and the reserved safety distance; a parking safety frame is calculated according to the vehicle body size and the minimum reserved safety distance; selecting a parking space which can meet the parking safety frame as a candidate parking space; a parking path is planned according to the candidate parking spaces, a plurality of point positions are taken on the parking path, parking safety frames are sequentially distributed on the point positions in the tangential direction of the parking path, and the space formed by overlapping the parking safety frames on the parking path serves as the minimum parking safety space; when it is sensed that no obstacle exists in the minimum parking safety space, the candidate parking space is released to serve as a target parking space.
本发明属于辅助泊车技术领域,为提高泊车成功率,提供了一种计及泊车成功率的车位释放方法、系统与智能泊车方法,建立泊车成功率与预留安全距离的关联关系,设置泊车成率,并根据泊车成功率与预留安全距离的关联关系匹配出能够满足泊车成功率设定值的最小预留安全距离;根据车身尺寸与最小预留安全距离计算泊车安全框;选择能够满足泊车安全框的车位作为候选车位;根据候选车位规划泊车路径,在泊车路径上取若干点位,并在点位上沿泊车路径的切线方向依次分布泊车安全框,泊车安全框在泊车路径上叠加而成的空间作为最小泊车安全空间;当感知到最小泊车安全空间内没有障碍物时,释放所述候选车位作为目标车位。
