The invention discloses a braking control method, system and device for a commercial vehicle with multiple braking systems, and the method comprises the steps: obtaining the information of the braking state of the vehicle; the information of the vehicle braking state comprises information of a vehicle braking control state and information of a vehicle braking controlled state; according to the braking state of the vehicle, the sub-braking systems in the multi-braking system of the vehicle conduct braking independently or jointly. According to the scheme, the information of the vehicle brake control state is expressed based on the treading state of the pedal, a feedback mechanism is formed corresponding to the information of the vehicle brake controlled state of independent or common braking of the sub-brake systems in the multi-brake system, and brake control and brake response are kept consistent. The auxiliary braking subsystem preferentially outputs the braking torque, the braking duration and strength of the EBS air braking subsystem are reduced as much as possible, the EBS air braking subsystem can be kept effective in long-slope and other long braking scenes, and the braking reliability is improved.

    本申请公开了一种多制动系统商用车制动控制方法、系统及装置,方法包括,获取车辆制动状态的信息;所述车辆制动状态的信息包括,车辆制动控制状态的信息和车辆制动受控状态的信息;根据所述车辆制动状态,车辆的所述多制动系统中各子制动系统单独或共同制动。通过上述方案,基于踏板的踩踏状态表达车辆制动控制状态的信息,对应多制动系统中各子制动系统单独或共同制动的车辆制动受控状态的信息形成反馈机制,使制动控制与制动响应保持一致。以辅助制动子系统优先输出制动力矩,尽量减少EBS气压制动子系统的制动时长和强度,有利于长坡等长制动场景下保持EBS气压制动子系统有效,提高制动可靠性。
