The invention provides an automobile collision early warning method and system, a computer and a storage medium, and the method comprises the following steps: obtaining a collision risk in real time based on a collision risk prediction model, and judging whether the collision risk is greater than a preset threshold; if the collision risk is larger than a preset threshold value, whether the vehicle is in a curve driving state or not is judged; if the vehicle is in the curve driving state, whether the front vehicle and the vehicle are in the same lane or not is judged; if the front vehicle and the vehicle are located on the same lane, the expected acceleration is reduced, and collision early warning is given out. Through risk prediction and intervention according to the speed and the distance at the next moment, compared with collision early warning based on current vehicle speed and distance judgment in the prior art, namely a mode that the acceleration of the vehicle is zero by default, the collision risk prediction accuracy is improved, and when the collision risk is larger than the preset threshold value, the risk intervention is performed. By judging whether the vehicle is in the curve driving state or not, the situation of false early warning or even false braking is avoided, and the driving experience is improved.
本发明提供一种汽车碰撞预警方法、系统、计算机及存储介质,该方法包括以下步骤:基于碰撞风险预测模型实时获取碰撞风险,并判断碰撞风险是否大于预设阈值;若碰撞风险大于预设阈值,判断本车是否处于弯道行驶状态;若本车处于弯道行驶状态,判断前车与本车是否处于同一车道;若前车与本车处于同一车道,降低期望加速度并发出碰撞预警。通过根据下一时刻的速度及距离进行风险预测及干预,相对于现有技术中基于当前车速及距离判断进行碰撞预警,即默认本车加速度为零的方式,提高了碰撞风险的预测准确度,当碰撞风险大于预设阈值时,通过判断本车是否处于弯道行驶状态,来避免出现误预警甚至误制动的情况,提高驾驶体验。
