The invention relates to a cooling and lubricating system, an automobile and an automobile control method, is applied to an electric drive system of the automobile and comprises an electric control cooling loop, a first cooling loop and a second cooling loop. The electric control cooling loop comprises an electric control cooling pipeline, a cooling pump and a radiator; the first cooling loop comprises a first cooling pipeline, a first pump motor, a first pump and a first cooler, and the first cooling pipeline communicates with a stator of a driving motor of the electric drive system so as to cool and lubricate the stator; the second cooling loop comprises a second cooling pipeline, a second pump motor, a second pump and a second cooler, and the second cooling pipeline communicates with a rotor of a driving motor of the electric drive system and a speed reducer of the electric drive system so as to cool and lubricate the rotor and the speed reducer. The stator is cooled and lubricated through the first cooling loop, the rotor and the speed reducer are cooled and lubricated through the second cooling loop, the cooling and lubricating efficiency of the electric drive system can be improved, and loss of cooling liquid is reduced.
