The embodiment of the invention discloses an automobile brake torque determining method and device and a computer storage medium, and belongs to the technical field of vehicle engineering. The method comprises the steps that when a braking instruction is received, the carbon loading capacity and a first torque of a GPF in an automobile are obtained, and the first torque is the torque of safe operation of an engine of the automobile in the GPF active regeneration process; when the carbon loading capacity is larger than or equal to a carbon loading capacity threshold value, a second torque is obtained according to the rotating speed of the automobile engine; and the minimum torque in the first torque and the second torque is determined as a brake torque of the automobile, and the brake torque is used for limiting the temperature of the GPF in the regeneration process. According to the embodiment of the invention, when the carbon loading capacity of the GPF exceeds the carbon loading capacity threshold value, the brake torque of the automobile can be limited again, so that the possibility that the GPF is burnt down under the condition of high carbon loading capacity is reduced, and the safety of the GPF and the engine is further protected.

    本申请实施例公开了一种汽车的制动扭矩确定方法、装置及计算机存储介质,属于车辆工程技术领域。所述方法包括:当接收到制动指令时,获取所述汽车中颗粒物捕集器GPF的碳载量和第一扭矩,所述第一扭矩为所述汽车的发动机在所述GPF主动再生过程中安全运行的扭矩;当所述碳载量大于或等于碳载量阈值时,根据所述汽车发动机的转速获取第二扭矩;将所述第一扭矩和所述第二扭矩中最小的扭矩确定为所述汽车的制动扭矩,所述制动扭矩用于限制所述GPF在再生过程中的温度。本申请实施例通过在GPF的碳载量超出碳载量阈值时,能够对汽车的制动扭矩重新进行限制,从而降低高碳载量情况下GPF烧毁的可能性,进而保护了GPF和发动机的安全。
