Problems solved by technology
However, using the clutch for a long time will cause the driver to experience driving fatigue, resulting in incomplete clutch disengagement or too fast release of the clutch leading to dead fire, and more serious traffic accidents may occur
[0003] In addition, the existing automobile clutch technology fails to realize intelligent identification and adaptation to the driver's own situation, and has strict requirements on the driver's own controllability of the clutch pedal, which may easily lead to driving accidents

Embodiment 1
[0027] Such as figure 2 As shown, the variable pressure automotive hydraulic clutch booster system of the present invention includes a pressure sensor, a microcomputer 12, a motor oil pump 5 and a throttle valve 6, and the pressure sensor is provided with at least two, which are installed under the driver's seat and the clutch respectively. On the pedal 1, the pressure sensor A installed under the driver's seat is connected to the microcomputer through a signal transmission line, and the pressure sensor B installed on the clutch pedal is connected to the microcomputer through a signal transmission line. The throttle valve is installed on the liquid storage tank 4 of the automobile hydraulic clutch, connected with the hydraulic master cylinder 3 of the automobile hydraulic clutch through the oil delivery pipe 9, and connected with the microcomputer through the signal transmission line. The motor oil pump is connected with the microcomputer through the signal transmission line,...

The invention relates to a variable pressure type automobile hydraulic type clutch power assisting system and a variable pressure type automobile hydraulic type clutch power assisting method. The variable pressure type automobile hydraulic type clutch power assisting system and the variable pressure type automobile hydraulic type clutch power assisting method can accurately apply equilibrant forceto a clutch, and prolong use life of the clutch on the premise of improving driving safety. The variable pressure type automobile hydraulic type clutch power assisting system comprises at least two pressure sensors, a controller, a motor oil pump and a throttle valve, wherein the pressure sensors are respectively installed below a driving seat and on a clutch pedal, the throttle valve is installed on a liquid storage tank, and connected with a hydraulic master pump through an oil conveying pipe, the motor oil pump is connected with the hydraulic master pump and the liquid storage tank respectively through another two oil conveying pipes, the pressure sensors below the driving seat collect weight information of a driver, convert the weight information into pressure data, and transmit the pressure data to the controller for the controller to perform comparison and identification between the pressure data and a preset big data range, the pressure sensors on the clutch pedal collect pressure data of the clutch pedal and transmit the pressure data of the clutch pedal to the controller for statistics, and the controller calculates out equilibrant force of the motor oil pump according toa comparison and identification result and a statistical result, converts the equilibrant force of the motor oil pump into a command, and sends the command to the motor oil pump.
Description
technical field [0001] The invention belongs to the technical field of automobile clutch intelligent booster, and in particular relates to a variable-pressure automotive hydraulic clutch booster system and method. Background technique [0002] The clutch is one of the most important parts in the car, and it is also one of the parts that need to be directly controlled by the driver. The structure of the existing clutch is as figure 1 As shown, its function is to temporarily disconnect or gradually combine the engine and transmission according to the driver's needs, so that the car can start smoothly or shift gears. However, using the clutch for a long time will cause the driver to experience driving fatigue, resulting in incomplete clutch disengagement or too fast release of the clutch leading to dead fire, and more serious traffic accidents may occur. [0003] In addition, the existing automobile clutch technology fails to realize intelligent identification and adaptation ...
