The invention relates to the technical field of vehicle intelligent driving, in particular to a vehicle lane changing decision-making method, which comprises the following steps: acquiring actual driving data of a target vehicle driver, and determining a driving style of the driver; obtaining the current following speed of the target vehicle on the original lane, and determining the safe acceleration of the target vehicle according to the driving style; calculating a car-following safe distance between the target vehicle and a front vehicle on the same lane by using a preset car-following safe distance model established based on the safe acceleration; whether the current actual distance between the target vehicle and the front vehicle meets the lane changing requirement or not is judged in combination with the car-following safety distance, and if yes, lane changing is allowed; otherwise, prompting to forbid lane changing. According to the technical scheme, due to the fact that the driving style of the driver is considered, the calculation result can conform to the actual driving condition of the target vehicle, and the driver can be effectively helped to make a lane changing decision.
本发明涉及车辆智能化驾驶技术领域，尤其涉及一种车辆换道决策方法车辆换道决策方法，包括：获取目标车辆驾驶者的实际驾驶数据，确定所述驾驶者的驾驶风格；获取所述目标车辆在原车道的当前跟驰车速，并根据所述驾驶风格，确定所述目标车辆的安全加速度；利用基于所述安全加速度建立的预设跟驰安全距离模型，计算所述目标车辆与同车道前车之间的跟驰安全距离；结合所述跟驰安全距离，判断所述目标车辆与所述前车之间的当前实际距离是否符合换道要求，若是，允许换道；否则，提示禁止换道。本发明的技术方案，由于考虑了驾驶者驾驶风格，使得计算结果较能符合目标车辆的实际行驶情况，从而能够有效帮助驾驶者进行换道决策。
