The invention discloses a deduction lattice-based bottom line decision-making method and device, and belongs to the technical field of automatic driving. Generating a deduction lattice according to the bottom line rule set; starting from a first sub-node under the deduction lattice root node, judging whether a feature corresponding to the node is true or not; if not, inspecting whether the characteristics corresponding to the adjacent brother nodes of the child node are true until the leaf node is reached; if yes, setting the current rule as a currently matched rule, and executing S1; if not, judging whether default is empty or not; s2, if the current rule is null, generating a new rule on the premise of the matched feature set and any conclusion, setting the current rule as the newly generated rule, and executing S2; if the current rule is not null, setting the current rule as default and executing S1; s1, according to the conclusion of the current rule, evaluating whether a corresponding strategy is satisfied; if not, executing S2; and S2, according to a direct bottom line rule, evaluating whether a corresponding strategy is satisfied according to a sequence.

    本发明公开了一种基于推演格的底线决策方法及装置,属于自动驾驶技术领域。由底线规则集生成推演格;沿着推演格根节点下的第一个子节点开始,判断该节点所对应的特征是否成立;若否,考察该子节点的邻接兄弟节点所对应的特征是否成立直至到达叶子节点;若是,设置当前规则为当前匹配的规则,执行S1;若否,判断default是否为空;若为空,生成一条新的规则,新规则的前提是已经匹配的特征集,结论是任意的结论,并将当前规则设置为新生成的规则并执行S2;若不为空,设置当前规则为default并执行S1;S1根据当前规则的结论评估对应的策略是否满足;若不满足,执行S2;S2根据直接底线规则按照顺序评估对应的策略是否满足。
