The invention discloses a brake-by-wire method, device and equipment and a computer readable storage medium, and belongs to the technical field of brake-by-wire. The method comprises the steps that braking information of a vehicle and loads borne by all wheels are obtained; based on the braking information and the load borne by each wheel, the average ideal braking force of each wheel of the front axle and each wheel of the rear axle is determined; the wheels are braked according to the average ideal braking force, and rolling and sliding information of the vehicle is synchronously obtained in the braking process; determining a ground braking force based on the rolling slip information; based on the average ideal braking force and the ground braking force, the final braking force of each wheel is determined; and on the basis of the final braking force, the clamping force of the friction plate on the brake disc is controlled, so that braking speed reduction or parking is realized, the dangerous conditions of sideslip, drifting, steering loss, frequent intervention of an ABS (Anti-lock Brake System) and the like caused by the fact that the front wheel or the rear wheel is locked in advance due to the fact that the brake is attached to an extreme road surface and ground adhesive force is not fully utilized are avoided, and discomfort brought to a user due to braking nodding can be avoided.
一种线控制动方法、装置、设备及计算机可读存储介质,属于线控制动技术领域。其中,方法包括:获取车辆的制动信息和各车轮承载的载荷;基于制动信息和各车轮承载的载荷,确定前轴各车轮和后轴各车轮的平均理想制动力;按照平均理想制动力对各车轮进行制动,在制动过程中同步获取车辆的滚动滑移信息;基于滚动滑移信息,确定地面制动力;基于平均理想制动力和地面制动力,确定各车轮的最终制动力;基于最终制动力,控制摩擦片对制动盘的夹紧力,从而实现制动减速或停车,避免在极限附着路面,未充分利用地面附着力,出现前轮或后轮提前抱死,导致侧滑、甩尾、失去转向、ABS频繁介入等危险情况,且可避免因制动点头给用户带来的不适。
