Background technology
Automobile chassis brake module, traditional fuel vehicle, driver's brake pedal, by vacuum booster, it will drive
The power that the person of sailing steps on brake pedal is amplified to promote master cylinder piston, is produced the braking oil pressure in Motor Vehicle Braking Procedure, is realized automobile
Braking；With the development of science and technology, existing new-energy automobile pressurizes to master cylinder according to similar iBooster modes, because pedal is defeated
It is decoupling to enter between bar and master cylinder, and it is no longer to promote master cylinder piston to be pressurizeed to master cylinder that driver, which steps on brake pedal, master cylinder pressurization
Being realized by motor, driver steps on brake pedal and is intended only as a signal, to judge the braking intention of driver, inspection
After the intention for measuring driver, the torque of controlled motor and rotating speed realize the pressurization of master cylinder, realize the braking of automobile；Therefrom may be used
To find out, the braking intention i.e. detection of brake pedal position of driver is detected as the unique signal input of system, keeps inspection
The reliability and accuracy of survey are particularly significant.
That brake pedal position is detected in existing similar iBooster products mainly has two kinds of forms, and the first is that angle passes
Sensor is arranged at brake pedal, and the angular transducer that product is borrowed on brake pedal produces the input of signal, but angle sensor
The installation of device is relevant with the form of brake pedal, and the brake pedal of different automobile types has different requirements to the shape of angular transducer
And the requirement in angular transducer installation process to axiality is also higher, it is soft that the angular transducer of different model also increases the later stage
Debug also bad with the workload in calibration process, the integrality of product in part part.
Another kind is used as magnetic ring induction type displacement transducer, is inputted by detecting the pedal being connected with brake pedal
The displacement of bar is used as the intention for judging operator brake, and the program adds two magnet rings in interiors of products, by sensing two
The change in location of magnet ring detects the stroke of pedal, but which is higher to the status requirement of two magnet rings and sensor, and magnetic
Ring induction type is larger by external interference, and the stability and accuracy of signal input cannot be guaranteed.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to a kind of transmission device using stabilization is now provided by pedal
The displacement of input lever is converted to the change of angle, greatly improve reliability and
The device of preparatory detection brake pedal position.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of device for detecting brake pedal position,
Its innovative point is：Including brake pedal connector, master cylinder push rod device, transmission device, angular transducer connector and angle
Sensor, the brake pedal connector are fixedly connected with master cylinder push rod device, the other end of the master cylinder push rod device
It is fixedly connected with transmission device, the other end of the transmission device is entered by angular transducer connector with angular transducer
Row drive connection.
Further, the master cylinder push rod device includes master cylinder push rod b and housing b, one end of the master cylinder push rod b and system
Dynamic tirasse is fixedly connected, and the other end of the master cylinder push rod b runs through housing b.
Further, the transmission device is rack and pinion drive, and the rack and pinion drive passes for gear
Dynamic device, one end and the housing b of the gear drive are fixedly connected, and the other end of the gear drive passes through
Angular transducer connector is connected with angular transducer.
Further, the gear drive is fixedly mounted on master including rack, gear and connecting rod b, the rack
Cylinder push rod b upper end, the gear are arranged on the upper end of rack, are used cooperatively with rack, the gear passes through company
Extension bar b carries out coaxial transmission with angular transducer connector.
Beneficial effects of the present invention are as follows：The present invention is by using brake pedal connector by brake pedal and master cylinder push rod
It is attached, the motion of brake pedal is converted into the linear motion of master cylinder push rod, the linear motion of master cylinder push rod passes through transmission
Device is converted to the change of angle, so as to by the change of angular transducer detection angles, judge to drive by angle variable quantity
The braking intention for the person of sailing, testing result is more reliable, as a result more accurate.
Brief description of the drawings
Fig. 1 is the structural representation of the device of the detection brake pedal position using rack and pinion drive of the present invention
Figure.
Embodiment
