The invention discloses a clutch control system, a clutch system, an automobile and a TCU of the automobile. The clutch control system comprises a drive mechanism and a work cylinder; the work cylinder comprises a first piston, a second piston and a pressure transmission medium located between the first piston and the second piston, the first piston and the second piston are arranged in a piston cavity, the first piston is connected to the output end of the drive mechanism, the second piston is used for being connected with a clutch, and a reset mechanism is arranged in the piston cavity where the second piston is located; the drive mechanism is used for driving the first piston, the pressure transmission medium and the second piston to move until the clutch is engaged, and is further used for driving the first piston to move reversely, and the reset mechanism is used for driving the second piston to reversely move until the clutch is disengaged. According to the scheme, the clutch control system is simple in structure, static pressure drive of the clutch is achieved, the utilization efficiency of pressure transmission media is high, a precise valve element system is not needed, the machining difficulty is low, the control difficulty is low, and reliability and stability of the clutch control system are improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a clutch control system, a clutch system, an automobile and an electronic control unit thereof. Background technique [0002] Existing clutch control systems include: [0003] Oil supply mechanism, including the oil tank and the oil pump in it; [0004] The solenoid valve of the main oil circuit, its oil inlet is connected with the oil pump; [0005] Clutch pressure solenoid valve, its oil inlet is connected with the main oil circuit solenoid valve; [0006] Clutch working cylinder, its piston cavity communicates with the oil outlet of clutch pressure solenoid valve, piston cavity is provided with piston, and piston is connected to clutch through push rod. [0007] During the clutch engagement process, the oil pump is first controlled to pump oil, the system pressure is established through the main oil circuit solenoid valve, and hydraulic oil is supplied to the clutch pre...
