Description
Technical field
The utility model is related to the safe practice of operating passenger car, particularly a kind of Anti-side-turning device of car.
Background technology
Along with developing rapidly for China's economy, auto industry has also obtained significant progress with transportation.City
The tradition car such as public transport, suburb regular bus, tourist bus and school bus, is whether obtained for pole from handling capacity of passengers or ride quality
Big improvement.But, because the automobile travelled on road is more and more；And along with the increasingly perfect of road network, automobile
Travel speed is also greatly improved, and these will all be very likely to and cause motor traffic accidents.At the same time, because operating passenger car car
Type is larger and carrying number often this more special circumstances, would generally cause serious lives and properties when occurring traffic accident
Loss, so the driving safety of operating passenger car is increasingly paid close attention to by people, especially extremely incident car rollover meaning
Outside.At present, most of operating passenger cars are main reduces rollover trend in the way of differential braking, by control checking cylinder oil pressure come
Change the brake force on one or several wheels, so that rollover is prevented, but there is certain unstability in such a method, for
Different cars, structure, the parameter of brakes is different, and easily occurs because brake fluid is not enough in control process,
Or circuit is the problems such as break down.
The content of the invention
To solve the above mentioned problem that prior art is present, the utility model will design a kind of stability and preferably be based on air
Dynamic (dynamical) car Anti-side-turning device.
To achieve these goals, the technical solution of the utility model is as follows：One kind is prevented based on aerodynamic car
Laterally turning-over device, including car running computer ECU, vehicle speed sensor, steering wheel angle sensor, steering wheel angle velocity sensor and car
Disturbing flow device is pushed up, described car running computer ECU passes through data wire and vehicle speed sensor, steering wheel angle sensor, direction respectively
Disk angular rate sensor and the connection of roof disturbing flow device；Described roof disturbing flow device includes left flow-disturbing passage and right flow-disturbing is logical
Road, described left flow-disturbing passage and right flow-disturbing passage are respectively arranged in roof both sides, and flow-disturbing channel interior is some groups of flow perturbation fans
Piece, is conventional spoiler structure.
Method of work of the present utility model, comprises the following steps：
A, identification rollover condition
Wheel speed sensors, steering wheel angle sensor and steering wheel angle velocity sensor continuous firing, by speed, direction
Disk corner and steering wheel angle speed send car running computer ECU to, and the judgement of rollover condition is carried out by car running computer ECU, once
Judge that car has the trend of rollover, then go to step B, otherwise repeat step A.
B, assessment rollover grade
When speed exceedes setting speed V1When, roof disturbing flow device unconditionally will start immediately, to prevent car from turning suddenly
It is curved, occur rollover event.When speed is less than setting speed V1, but higher than setting speed V2When, due to turning on one's side to steering wheel angle
Change is more more sensitive than steering wheel tarnsition velocity, so starting to judge steering wheel angle.Now, if steering wheel angle it is exhausted
When being higher than set angle θ to value, disturbing flow device is just started working.And when speed is higher than setting speed V2, and steering wheel angle is exhausted
Set angle θ is less than to value, car running computer ECU will determine that steering wheel angle speed.As long as steering wheel angle speed is exhausted this moment
To value higher than angular velocity omega is set, then roof disturbing flow device immediately enters working condition.Described setting speed V1More than setting
Speed V2。
Car running computer ECU calculates the transverse load rate of transform LTR of automobile, entered according to the data of the obtained data of step A
And the assessment of rollover grade is carried out, complete after calculating, control instruction is sent to roof disturbing flow device.
C, the on-off action for controlling roof disturbing flow device
Under normally travel state, the left and right flow-disturbing passage of roof disturbing flow device is fully open, to increase lower pressure, improves row
Sail stability；When car is turned, if according to rollover is assessed as after rollover grade evaluation process, opening turning medial
Flow-disturbing passage on the outside of flow-disturbing passage, closing, to provide a tilting moment for offsetting rollover, to maintain car smooth-ride shape
State.
Compared with prior art, the utility model has the advantages that：
1st, the utility model is judged rollover trend by car running computer ECU, is then filled by changing roof flow-disturbing
The left and right flow-disturbing passage switching put offset rollover produce tilting moment, so as to reach the purpose of anti-rollover.
2nd, the utility model is integrated the concept of anti-rollover under traditional concept and hyundai electronicses control system, from vehicle body
Aerodynamics angle carries out anti-rollover control, and control mode is more direct effective.
3rd, the utility model has taken into account the riding stability of high center of gravity car while the purpose of anti-rollover control is reached
Problem, can increase the lower pressure suffered by car under normally travel state, so as to improve ground under the operating mode run at high speed
Face adhesive force.
Brief description of the drawings
Fig. 1 is composition schematic diagram of the present utility model.
Fig. 2 is rollover condition identification process figure.
Fig. 3 is rollover grading flow chart.
Fig. 4 is the front view that single group flow-disturbing passage is onboard installed.
Fig. 5 is the top view that single group flow-disturbing passage is onboard installed.
Embodiment
The utility model is explained below in conjunction with the accompanying drawings.As shown in figure 1, the utility model mainly includes three
Sensor：Vehicle speed sensor, steering wheel angle sensor and steering wheel angle velocity sensor.Three sensors are by respective number
It is believed that number being sent to car running computer ECU, car running computer ECU passes through built-in algorithms, i.e. rollover condition identification module and rollover condition
Module of grading carries out rollover related data LTR calculating, a control signal is exported, so that system is turned on and off, on roof
Flow-disturbing passage be turned on and off therewith.
Fig. 2 is rollover condition identification process figure.If V1=60km/h, V2=20km/h, θ=120 °, ω=200 °/s, when
When speed is more than 60km/h, control system unconditionally will start immediately, to prevent car from turning suddenly, occur rollover event.When
Speed is less than 60km/h, but during higher than 20km/h, due to turning on one's side the change to steering wheel angle than steering wheel tarnsition velocity more
For sensitivity, so starting to judge steering wheel angle.Now, as long as the absolute value of steering wheel angle is higher than 120 °, system is just opened
Beginning work.And when speed is higher than 20km/h, and 120 ° of steering wheel angle absolute value, system will determine that steering wheel angle speed.Only
Will this moment steering wheel angle speed absolute value be higher than 200 °/s, then system immediately enter working condition.
Fig. 3 is rollover grading flow chart, as illustrated, fixed algorithm is by classical Three Degree Of Freedom automobile mechanics model,
The transverse load rate of transform LTR of car is calculated by steering wheel angle and speed, so as to judge visitor by LTR numerical values recited
The rollover grade of car, and then better control over the opening and closing of system.
When control system judges that car has the trend of rollover, normally opened roof flow-disturbing passage natural sciences enter working condition,
System will close the flow-disturbing passage on the outside of turning and keep the flow-disturbing passage of turning medial to open, and produces one and offsets rollover torque
Tilting moment so that reach prevent rollover purpose.
