The invention discloses a long downhill road section truck driving state early warning method and system. The method comprises the steps that the total weight, obtained by a truck weighing unit, of a truck is received; receiving the current speed of the truck acquired by a vehicle speed identification unit; the vehicle speed recognition unit is at least arranged at one position in front of an entrance of the emergency lane by a preset distance; and according to pre-stored risk avoiding basic parameters of a risk avoiding lane, the current speed of the truck and the total weight of the truck, calculating a driving distance when the truck drives into the risk avoiding lane at the current speed and the speed is reduced to 0, recording the driving distance as a first distance, judging whether the first distance is greater than the length of the risk avoiding lane, and if so, outputting early warning information. Through the method, a driver can be prompted to reduce the vehicle speed, and the possibility that the vehicle rushes out of the emergency lane when being out of control suddenly is reduced.
本申请公开了一种长下坡路段货车行驶状态预警方法和系统,包括:接收货车计重单元获取的货车的总重;接收车速识别单元获取的所述货车当前速度;所述车速识别单元设置至少在避险车道入口前预设距离设置一处;根据预先存储的避免车道的避险基本参数、所述货车当前速度以及所述货车的总重计算货车以当前速度驶入避险车道时,速度降为0时行驶的距离,记为第一距离,判断所述第一距离是否大于避免车道长度,若是,则输出预警信息。通过本申请方法,能够提示司机降低车速,降低车辆在突然失控时冲出避险车道的可能性。
