The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, Fig. 2, a kind of controllable type pedal sense simulator, including pedal push rod 6, for pushing the pedal to push away
The brake pedal 1 of bar 6 and signal gear component 8 with the pedal push rod 6 cooperation, when manual braking, the signal gear
Component 8 is used to detect the stroke of the pedal push rod 6 and is provided according to the stroke of the pedal push rod 6 to the pedal push rod 6
Reaction force, reaction force here, which refers to, provides a power opposite with 6 direction of motion of pedal push rod.For example, position shown in Fig. 1
It sets, when brake pedal 1, brake pedal 1 will push pedal push rod 6 and move downward, at this point, reaction force is to pedal
Push rod 6 applies power to the right.When unmanned braking, the signal gear component 8 is for pushing the pedal push rod 6 to be made
Dynamic, pushing the direction of pedal push rod 6 is to illustrate to the left.
The signal gear component 8 includes the motor 10 and use of signal gear 81, the control rotation of signal gear 81
It is offered and the signal in the detection unit for the stroke for detecting the pedal push rod 6, affiliated push rod 6 along its length
The rack gear 11 that gear 81 is meshed, the motor 10 are electrically connected to the entire car controller of automobile with the detection unit.Here
Working principle be: detection unit is used to detect the stroke of pedal push rod 6 and will test to judge the brake applications of driver
The pedal travel information conveyance arrived controls motor 10 according to the travel information received to entire car controller, subsequent entire car controller
Work, the output torque size of motor 10 are then determined according to the relation curve of the pedal displacement of setting and pedal force.According to
The different brake feel demand of driver, can be set the relation curve of different pedal displacement and pedal force.
In the present embodiment, the detection unit is the rotary angle transmitter for detecting 81 rotational angle of signal gear
83.During pedal push rod 6 moves downward, the rotation of signal gear 81, the letter that rotary angle transmitter 83 will test will drive
For the rotational angle information conveyance of number gear 81 to entire car controller, driving motor 10 exports corresponding torque.
The present embodiment is directly pushed away in the way of detection 81 rotational angle of signal gear of rotary angle transmitter 83 to obtain pedal
The stroke of bar 6 carries out the stroke detection of pedal push rod 6 without being further added by other structure, so that whole mechanism is more simple.
It is worth noting that be only a kind of preferable embodiment by the way of rotary angle transmitter 83, technology effect to realize the present invention
Fruit can still detect the stroke of pedal push rod 6 using other detection modes, such as setting stroke sensor is direct
The stroke of pedal push rod 6 is detected, function of the invention still may be implemented in this mode, and difference is only that and can add
More auxiliary element, specific structure are not described herein.
It is improved as preferable, the signal gear component 8 further includes being set to the signal gear 81 and rotation angular sensing
Magnet 82 between device 83, the rotary angle transmitter 83 detect the angle of rotation of the signal gear 81 by the magnet 82
Degree.The principle of this mode is set using Hall effect, and rotary angle transmitter 83 reads signal teeth based on Hall effect
The angle of rotation angle value of wheel 81.
The controllable type pedal sense simulator further includes the reduction gearing 9 engaged with the signal gear 81, the electricity
Machine 10 couples with the reduction gearing 9.The output shaft of the motor 10 is connect with 9 interference of reduction gearing.Motor 10 it is defeated
Torque is exported by reduction gearing 9 to signal gear 81 out.
The controllable type pedal sense simulator further includes connector 3, one end of the connector 3 and the pedal push rod
6 connections, the other end are connect with the brake pedal 1.Specifically, the connector 3 be U-shaped button, the open end of the U-shaped button with
The pedal push rod 6 is threadedly coupled, shown referring to Fig.1, is connected in one end of U-shaped button and pedal push rod 6 by locking nut 4
It connects, the closed end of the U-shaped button is coupled by a fulcrum post 2 with the brake pedal 1.It is sliding that bar shaped is offered on brake pedal 1
Slot, 2 activity of fulcrum post pass through the bar shaped sliding slot and can slide in the bar shaped sliding slot.
The controllable type pedal sense simulator further includes shell 7, and the pedal push rod 6 runs through the shell 7 and can edge
Through direction sliding, the signal gear component 8 are set in the shell 7.Shown position referring to Fig.1, pedal push rod 6 is from outer
The enclosure interior of shell 7 passes through, and there are two places intersected in diagram left and right with shell 7, is arranged on the shell of the shell 7
There are axle bush sleeve 5, the pedal push rod 6 and 5 transition fit of axle bush sleeve.Pedal push rod 6 and shell 7 is arranged in axle bush sleeve 5
Pedal push rod 6 can guarantee that rack gear 11 and signal gear 81 on pedal push rod 6 are kept with 5 transition fit of axle bush sleeve by intersection
Correct meshing relation.Motor 10 is set on the shell of the shell 7.
The signal gear 81 is located at the lower section of the pedal push rod 6.
Working principle to the present embodiment under manual braking's mode and unmanned braking mode below.
When manual braking's mode, 10 output torque of motor can carry out deceleration torque increase by reduction gearing 9 and signal gear 81,
And it is transferred to the rack gear 11 on pedal push rod 6, corresponding resistance is generated to pedal push rod 6.When manpower brake pedal 1,
It can overcome resistance that pedal push rod 6 is pushed to move forward, 6 stroke of pedal push rod is bigger, and the output torque of signal gear 81 is also corresponding bigger,
The damping force of generation is also bigger, and by providing pedal sense to driver in U-shaped button feedback to brake pedal 1.Pedal travel
With the corresponding relationship of pedal force, can be changed by controlling the output torque of motor and realizing.
When unmanned braking mode, brake signal is exported by entire car controller, 10 output torque of motor can be by slowing down
The rack gear 11 that gear 9 and signal gear 81 carry out deceleration torque increase, and be transferred on pedal push rod 6, generates accordingly pedal push rod 6
Thrust, push pedal push rod 6 move forward, generate brake force.
The stroke of detection unit detection pedal push rod 6 of the present invention can control motor 10 according to the stroke of pedal push rod 6
Suitable torque is exported, so that signal gear 81 applies the power opposite with its stroke to pedal push rod 6, the size of this power can be with
It is set, it can realize that same vehicle provides different pedal senses for driver；Also, the present invention also have its second
A function, i.e., unpiloted braking, unpiloted mode of braking are directly to pass through entire car controller driving motor 10, benefit
Pedal push rod 6 is pushed directly on signal gear 81 to be braked.Overall structure of the invention is simple, popularization easy to produce.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
