The invention discloses an early-warning braking method and a device for an automatic driving vehicle, the vehicle and a storage medium. The method comprises the following steps: detecting an early-warning braking instruction of the automatic driving vehicle; recognizing the target deceleration of the autonomous vehicle according to the current vehicle speed range of the autonomous vehicle and the current active decompression available state of the brake actuator while detecting the early warning braking instruction and performing early warning reminding; and correcting the target pressure of the brake actuator by the target deceleration until the actual deceleration of the autonomous vehicle reaches the target deceleration. Therefore, the problem that in the prior art, an electric brake is selected on a brake actuator for braking, but the problem cannot be achieved for a vehicle without the electric brake is solved, sudden movement of the vehicle or safety accidents are avoided, and the safety of a driver is effectively improved.
本申请公开了一种自动驾驶车辆的预警制动方法、装置、车辆及存储介质,其中,方法包括:检测自动驾驶车辆的预警制动指令;在检测到预警制动指令并进行预警提醒的同时,根据自动驾驶车辆当前所处的车速范围和制动执行器的当前主动减压可用状态识别自动驾驶车辆的目标减速度;由目标减速度修正制动执行器的目标压力,直至自动驾驶车辆的实际减速度达到目标减速度。由此,解决了相关技术中在制动执行器上选择了电动制动器进行制动,而对于未安装电动制动器车辆来说就无法实现的问题,不至于出现车辆突然窜动或者造成安全事故,有效地提升驾驶员的安全性。
