The invention provides a quick starting system for an automobile, and belongs to the technical field of automobiles. The quick starting system comprises a controller, a 48V BSG motor and a 48V battery, the controller is reused as a controller of the engine control unit, and the controller is used for sending a starting instruction to the 48V BSG motor and the 48V battery according to an obtained starting request; the 48V battery is used for supplying power to the 48V BSG motor according to the received starting instruction; the 48VBSG motor is used for dragging the engine to rotate according to the received starting instruction; the controller is further used for controlling the engine to conduct oil injection ignition when the rotating speed of the engine reaches a first set value. According to the quick start system, the information amount of CAN communication interaction is reduced, and the bus load rate is reduced, so that signal delay and error frame generation caused by CAN communication are eliminated.
本公开提供了一种用于汽车的快速启动系统,属于汽车技术领域。所述快速启动系统包括控制器、48VBSG电机和48V电池,所述控制器复用为所述发动机控制单元的控制器,所述控制器用于根据获取到的启动请求向所述48VBSG电机和所述48V电池发送启动指令;所述48V电池,用于根据接收到的启动指令,为所述48VBSG电机供电;所述48VBSG电机,用于根据接收到的启动指令,拖动发动机转动;所述控制器还用于当所述发动机的转速达到第一设定值时,控制所述发动机进行喷油点火。该快速启动系统减少了CAN通讯交互的信息量,降低了总线负载率,从而消除了CAN通讯带来的信号延迟和错误帧的产生。
