The invention discloses a kind of pedestrian's alarm set and EBA for pure electric automobile, including control module, vehicle speed sensor module, radar sensor module, audio storage module, brake pedal, driver's button and accept controller instruction execution module, execution module includes the loudspeaker reminded according to different speeds pedestrian and the motor according to the automatic auxiliary braking of distance objective thing range rate, wherein control module connects with above-mentioned module respectively successively, not only function fully meets car owner's requirement to the present invention, and security is higher, and thoroughly solve pure electric automobile and be not easy safety problem caused by being discovered by pedestrian.
Description
Technical field
The present invention relates to technical field of automobile control, especially a kind of pedestrian's alarm set for pure electric automobile and auxiliary
Help brakes.
Background technology
With the reinforcement of people's environmental consciousness and the progress of auto industry relevant technical, the recoverable amount of pure electric automobile is year by year
Soaring, pure electric automobile already turns into the representative of the green and healthy life style of people.Pure electric automobile is due to conventional fuel oil being driven
It is dynamic to be changed into electric power, it is very quiet in operation there is no obvious sound when it is travelled.Therefore it is in more noisy environment and right
The pedestrian for having dysacousis constitutes certain potential safety hazard.
The content of the invention
The technical problems to be solved by the invention are：A kind of pedestrian's alarm set and auxiliary for pure electric automobile is provided
Brakes, not only function fully meets car owner's requirement for it, and security is higher, and thoroughly solve pure electric automobile be not easy by
Safety problem caused by pedestrian discovers, with overcome the deficiencies in the prior art.
What the present invention was realized in：
A kind of pedestrian's alarm set and EBA for pure electric automobile, including control module, speed sensing
Device module, radar sensor module, audio storage module, brake pedal, driver's button and accept controller instruction perform mould
Block, execution module include the loudspeaker reminded according to different speeds pedestrian and according to distance objective thing range rate from
The motor of dynamic auxiliary braking, wherein control module connect with above-mentioned module respectively successively.
In a kind of foregoing pedestrian's alarm set and EBA for pure electric automobile, the audio storage mould
Block sets speed 40km/h as first threshold, corresponding pedestrian's prompt tone A；Speed 60km/h is Second Threshold, and corresponding prompt tone is
B；Speed 80km/h is the 3rd threshold value, and corresponding prompt tone is C；It is D that driver's button, which corresponds to prompt tone,；EBA is opened
When prompt tone be E.
In a kind of foregoing pedestrian's alarm set and EBA for pure electric automobile, the vehicle speed sensor
Detect and signal is issued into control module after vehicle real-time speed, the threshold value in control module combination audio storage module, to not
Corresponding prompt tone is extracted with speed, and control signal is sent to loudspeaker.Control signal reaches loudspeaker via audio transmission line,
Loudspeaker sends prompt tone.
In a kind of foregoing pedestrian's alarm set and EBA for pure electric automobile, radar sensor module
Get automobile and after the range information of neighbouring pedestrian, if range rate is less than predetermined range rate, controller is sent out
Go out control signal to motor, motor driving brake pedal is braked, and is played simultaneously to deserved prompt tone to driver and row
People is reminded.
In a kind of foregoing pedestrian's alarm set and EBA for pure electric automobile, in driver's button quilt
After triggering, controller suspends the processing to vehicle speed sensor module by signal, directly extracts driver's button to deserved prompt tone pair
Pedestrian is warned.
By adopting the above-described technical solution, compared with prior art, the degree of accuracy is high in use by the present invention, speed
Sensor assembly uses induction.Sensor is arranged on the non-rotating part of wheel set, and with wheel
The permeability magnetic material of rotation is relative.When gear ring relative sensors rotate, due to the change of magnetic resistance, alternation is motivated on a sensor
Voltage signal.The frequency of the signal is directly proportional to vehicle wheel rotational speed, and sensor signal is converted into same frequency by signal transacting
Square wave, then frequency or cycle by measuring square wave can obtain vehicle real-time speed；Sound intermediate frequency memory module storage of the present invention
Various forms of prompt tones.After GES is by accurate gather, control module extracts corresponding prompting according to threshold value respectively
Sound is reminded pedestrian, improves the hommization degree of automobile；It is driver's button list in pedestrian's alarm set in the present invention
Prompt tone solely is provided with, and is preferentially performed, is advantageous to processing of the driver to various emergency cases in driving conditions；In the present invention
The range information that the auxiliary brake system of radar sensor monitors according to radar, determine the open and close of auxiliary brake system.
When EBA is opened, adjoint prompt tone can effectively remind driver to carry out braking and pedestrian and be avoided, and reduce
The generation of traffic accident.
Brief description of the drawings
Accompanying drawing 1 is the principle schematic of the present invention.
Embodiment
Embodiments of the invention：A kind of pedestrian's alarm set and EBA for pure electric automobile, such as accompanying drawing
It is shown, including control module 1, vehicle speed sensor module 2, radar sensor module 3, audio storage module 4, brake pedal 5, drive
The person's of sailing button 6 and controller instruction execution module 7 is accepted, execution module 7 includes according to different speeds reminding pedestrian
Loudspeaker 8 and the motor 9 according to the automatic auxiliary braking of distance objective thing range rate, wherein control module 1 are distinguished successively
Connected with above-mentioned module.
Wherein the audio storage module sets speed 40km/h as first threshold, corresponding pedestrian's prompt tone A；Speed 60km/h
For Second Threshold, corresponding prompt tone is B；Speed 80km/h is the 3rd threshold value, and corresponding prompt tone is C；Driver's button correspondingly carries
It is D to show sound；Prompt tone when EBA is opened is E.
The vehicle speed sensor detects issues control module after vehicle real-time speed by signal, and control module combination audio is deposited
The threshold value in module is stored up, different speeds are extracted with corresponding prompt tone, and control signal is sent to loudspeaker.Control signal is via sound
Frequency transmission line reaches loudspeaker, and loudspeaker sends prompt tone.
The radar sensor module gets automobile with after the range information of neighbouring pedestrian, making a reservation for if range rate is less than
Range rate, then controller send control signal to motor, motor driving brake pedal is braked, and is played simultaneously pair
Deserved prompt tone is reminded driver and pedestrian.
After driver's button is triggered, controller suspends the processing to vehicle speed sensor module by signal, and directly extraction is driven
The person's of sailing button warns to deserved prompt tone to pedestrian.
The present embodiment solves pure electric automobile and leans on driven by power, and traveling is excessively quiet, is not easy caused by being discovered by pedestrian
Safety problem, propose a kind of pedestrian's alarm set and EBA for pure electric automobile.The system includes control mould
