The invention relates to a vehicle braking control method, a device using the same, a vehicle and an ECU. The method comprises the following steps: acquiring current state information of a target vehicle; when the current state information reaches a first preset condition, in-cylinder braking is started, and the in-cylinder braking grade is determined according to engine operation parameters of the target vehicle; and AMT gear shifting is controlled based on the in-cylinder brake grade. Wherein the current state information comprises the current accelerator opening degree of the target vehicle, the gradient of a road where the target vehicle is located currently, the current speed of the target vehicle and the current acceleration of the target vehicle. According to the method, the in-cylinder brake associated AMT gear shifting can be accurately controlled when the target vehicle runs on the downhill complex road, the in-cylinder brake and the AMT brake are controlled according to the current accelerator opening degree of the target vehicle, the gradient of the road where the target vehicle is located currently, the current speed of the target vehicle and the current acceleration of the target vehicle, and accurate control and fine control are achieved.

    本申请涉及一种车辆制动的控制方法及应用其的装置、车辆、ECU。所述方法包括:获取目标车辆的当前状态信息;在所述当前状态信息达到第一预设条件时开启缸内制动,并根据所述目标车辆的发动机运行参数确定缸内制动等级;基于所述缸内制动等级控制AMT变挡。其中,所述当前状态信息包括目标车辆的当前油门开度、目标车辆当前所处道路的坡度、目标车辆的当前速度、目标车辆的当前加速度。本申请能对目标车辆在下坡复杂道路行驶时准确控制缸内制动关联AMT换挡,根据目标车辆的当前油门开度、目标车辆当前所处道路的坡度、目标车辆的当前速度、目标车辆的当前加速度控制缸内制动和AMT制动,实现了精准控制和精细控制。
