The invention relates to an automobile electronic control unit. The automobile electronic control unit comprises a first chip; a second chip; and a switching circuit which is configured to connect thefirst chip with the two paths of direct current motor control circuits and disconnect the second chip from the two paths of direct current motor control circuits when the first chip works normally, and thus the parking brake motor corresponding to the two paths of direct current motor control circuits is controlled by the first chip; the switching circuit is further configured to disconnect the first chip from at least one direct current motor control circuit and enable the second chip to be connected with the at least one direct current motor control circuit when the first chip breaks down,and thus the parking brake motor corresponding to the at least one direct current motor control circuit is controlled by the second chip. The invention further relates to an automobile body stabilizing system, an automobile, a control method of the parking brake system and a computer storage medium.

    本发明涉及一种汽车电子控制单元,所述汽车电子控制单元包括:第一芯片;第二芯片;以及开关电路,其中,所述开关电路配置成在所述第一芯片正常工作时,将所述第一芯片与两路直流电机控制电路连接并断开所述第二芯片与所述两路直流电机控制电路的连接,使得由所述第一芯片控制与所述两路直流电机控制电路对应的驻车制动器电机;以及所述开关电路还配置成在所述第一芯片故障时,断开所述第一芯片与至少一路直流电机控制电路的连接,并使所述第二芯片与所述至少一路直流电机控制电路连接,使得由所述第二芯片控制与所述至少一路直流电机控制电路对应的驻车制动器电机。本发明还涉及车身稳定系统、汽车、驻车制动系统的控制方法以及计算机存储介质。
