detecting whether the oil pressure in the clutch oil cylinder is normal or not, and when the oil pressure in the clutch oil cylinder is abnormal, clamping the electromagnetic valve of the clutch;
and collecting and displaying fault information, and judging whether the vehicle can stop again.
10. A system for detecting a running fault of a dual-flow transmission vehicle, comprising:
a wheel speed sensor for measuring wheel speed information of the vehicle;
the Hall sensor is used for detecting a reference voltage value of the gear sensor;
the oil pressure sensor is used for detecting numerical values of transmission system oil pressure, gear shifting oil cylinder pressure and clutch oil cylinder oil pressure;
the parameter acquisition module is used for acquiring vehicle wheel speed information measured by the wheel speed sensor and judging fault type information existing in the vehicle;
the sensor fault module is used for acquiring a reference voltage value of the gear sensor detected by the Hall sensor and judging whether the gear sensor is in fault;
the oil pressure fault module is used for acquiring the oil pressure of the transmission system, the pressure of the gear shifting oil cylinder and the oil pressure value of the clutch oil cylinder detected by the oil pressure sensor and judging whether the system oil pressure is too low, the gear shifting solenoid valve is blocked and the clutch solenoid valve is blocked;
and the indicating module is used for displaying a program fault indicating lamp and other fault reason display equipment.
