The invention discloses a vehicle constant-speed braking method, device and equipment and a readable storage medium, and the vehicle constant-speed braking method comprises the steps that when it is detected that a vehicle runs downhill and a constant-speed function is started, the vehicle speed when the constant-speed function is started serves as the target vehicle speed, and the current vehicle speed of the vehicle is continuously monitored; when it is detected that the difference value between the current vehicle speed and the target vehicle speed within the preset duration is larger than the preset difference value, the vehicle is kept at the constant speed through gear downshift, engine braking and engine accessory braking; and after gear downshift, engine braking and engine accessory braking are executed, if it is detected that the difference value between the current vehicle speed and the target vehicle speed within the preset duration is larger than the preset difference value, braking is conducted through an electronic braking system, and the constant speed of the vehicle is maintained. According to the method, the vehicle is kept at the constant speed by fully utilizing gear downshift, engine braking and engine accessory braking, and if the vehicle is still difficult to keep at the constant speed, the electronic braking system is controlled to intervene in braking, so that the driving comfort is improved, and the braking cost is reduced.
一种车辆恒速制动方法、装置、设备及可读存储介质,车辆恒速制动方法包括:当检测到车辆下坡行驶且恒速功能开启时,以恒速功能开启时的车速为目标车速,并持续监测车辆的当前车速;当检测到当前车速和目标车速在预设时长内的差值大于预设差值时,通过挡位降挡、发动机制动以及发动机附件制动,以供维持车辆恒速;在挡位降挡、发动机制动以及发动机附件制动执行后,若检测到当前车速和目标车速在预设时长内的差值大于预设差值,则通过电子制动系统制动,以供维持车辆恒速。本申请通过,充分利用挡位降挡、发动机制动以及发动机附件制动使车辆维持恒速,如果车辆还是难以维持恒速,则控制电子制动系统介入制动,提高了驾驶舒适性降低了制动成本。
