The invention discloses a warning method for pedestrians outside a vehicle and a related device. The method comprises the steps that the corresponding relation between the bending degree and a sound pressure level adjustment value, the corresponding relation between the vehicle speed and a sound pressure level basic value, the current vehicle speed, the target bending degree and a basic sound source of warning sound for the pedestrians outside the vehicle are obtained; and determining a current sound pressure level adjustment value corresponding to the target bending degree according to the corresponding relationship between the bending degree and the sound pressure level adjustment value. And determining a current sound pressure level basic value corresponding to the current vehicle speed according to the corresponding relationship between the vehicle speed and the sound pressure level basic value. And obtaining a sound pressure level target value according to the current sound pressure level basic value and the current sound pressure level adjustment value. And playing the first warning sound determined by the sound pressure level target value. By combining the sound pressure level basic value with the sound pressure level adjustment value, the vehicle danger degree and the road danger degree are reflected, so that pedestrians outside the vehicle can be effectively reminded to pay attention to the driving vehicle by playing the first warning sound in places with high danger degrees, such as curves and intersections with high bending degrees.
本申请公开了一种车外行人警示方法及相关装置,方法包括:获取弯曲程度与声压级调整值的对应关系、车速与声压级基础值的对应关系、当前车速、目标弯曲程度和车外行人警示音的基础音源。根据弯曲程度与声压级调整值的对应关系,确定目标弯曲程度对应的当前声压级调整值。根据车速与声压级基础值的对应关系,确定当前车速对应的当前声压级基础值。根据当前声压级基础值和当前声压级调整值,得到声压级目标值。播放声压级目标值确定的第一警示音。通过结合声压级基础值与声压级调整值,反应车辆危险程度和道路危险程度,从而能在弯曲程度较大的弯道、路口等危险程度较高的地方,通过播放第一警示音,有效提醒车外行人注意行驶中的车辆。
