Abstract
本发明公开了一种车辆蠕动噪声的控制方法、系统、装置及存储介质和车辆，控制方法包括：获取车速、制动踏板的踏板行程及对应的主缸压力；根据踏板行程和主缸压力确定目标制动需求力；判断车速是否在各个车轮预设的蠕动噪声车速范围内；若存在车速在预设的蠕动噪声车速范围内，根据目标制动需求力分配各个车轮的制动压力。本发明实施例能够在不改变制动和驱动的情况下，减少车轮蠕动噪声，减低成本和开发周期，可广泛应用于车辆控制技术领域。

The invention discloses a control method, a system and a device for peristaltic noise of a vehicle, a storage medium and the vehicle, wherein the control method comprises the steps of obtaining the speed of the vehicle, the pedal travel of a brake pedal and the corresponding master cylinder pressure; the method comprises the steps of determining target braking demand force according to pedal travel and master cylinder pressure, judging whether the vehicle speed is in a preset creep noise vehicle speed range of each wheel, and distributing braking pressure of each wheel according to the target braking demand force if the vehicle speed is in the preset creep noise vehicle speed range. The embodiment of the invention can reduce the peristaltic noise of the wheels and reduce the cost and the development period under the condition of not changing the braking and driving, and can be widely applied to the technical field of vehicle control.
