On the other hand, millimetre-wave radar 3 is added in the utility model, and the signal and automobile energy of the millimetre-wave radar 3 return
It is mutually electrically mated to present module.Existing entire car controller mainly judges to drive by acquisition driver, the relevant information of vehicle itself
The intention for the person of sailing, so that vehicle be made to be in certain working condition, and it is different according to different driving conditions to be in vehicle
Energy feedback state is limited and is driven since current BMS system recovers energy to maximum to reach certain energy-saving effect
The driving habit for the person of sailing, uncertain, this energy-saving effect and the not up to optimal state of the operating status of other vehicles of road.
And the utility model introduces millimetre-wave radar 3 and goes to judge that front vehicles on road surface, the motion state of pedestrian (accelerate, slow down, movement
Direction).To be adjusted in advance to the motion state of vehicle, and carry out relevant energy feedback.Such as: it is currently marketed
Vehicle, since driver is unable to judge accurately whether front truck is in deceleration regime, driver often just steps on when close to front truck suddenly, at this time
Energy payback time it is short, physics brake loss energy it is more, the comfort of vehicle is also poor.After using this controller, control
It is deep by adjust automatically energy feedback when device processed determines the front vehicles speed of service lower than this vehicle by acquiring sensor information
Degree is to reduce speed.The frequency that driver touches on the brake is reduced, entire vehicle is made to be in stable operating status.To promote energy
The comfort of the rate of recovery and vehicle.3 major function of millimetre-wave radar be transmitting millimeter-wave signal, detection objects in front and this vehicle it
Between spacing, preceding vehicle speed.The relevant information detected is sent to single-chip microcontroller by differential signal line, single-chip microcontroller passes through correlation
Algorithm calculate preceding following distance, front truck and this vehicle relative velocity, whether safety, if preceding vehicle speed be less than this vehicle speed pacifying
Under the premise of full spacing, battery capacity is converted by braking energy while appropriate increase energy feedback dynamics reduces speed.
Stop energy regenerating when speed is consistent with front truck.When Ben Che and leading vehicle distance are less than safe spacing, increase back energy feedback
Dynamics allows this vehicle speed lower than front truck to widen the safe spacing between two vehicles.Be added millimetre-wave radar 3 for vehicle amount safety,
Energy-saving efficiency is improved.
On the other hand, six axle sensor modules 2 are added in the utility model, and solve vehicle amount and ran vehicle attitude variation
When, range tie and chassis related Control System are accurately adjusted, driving comfort is improved.
Six axle sensor modules, 2 major function is to judge the vehicle body state of vehicle, can by acceleration level sensor,
To judge whether the acceleration-deceleration of vehicle in the process of moving meets comfort requirement.It is to accelerate according to vehicle with this acceleration
Degree is adjusted to enhance the comfort of vehicle.It can be additionally used for collision detection, pass through the acceleration of detection level axis X-direction
The whether hurried increase of degree is to judge whether vehicle crashes.When detecting collision alarm, full-vehicle control is immediately to vehicle
Safety block issues action command to protect the safety of passenger.Y-axis acceleration transducer can be used for judging vehicle
Transverse movement state, for judging whether vehicle has the movement of lane change, turn.Turned by the way that Y-axis signal is sent to automobile chassis
To system, turn instruction system in the same direction.The speed and comfort level that can be turned round, can also be by being electrically connected turn signal before lane change
Achieve the effect that automatically turn on dynamic side marker light, and completes safe lane change.Z axis acceleration transducer is hanging down for detecting vehicle
Histogram to motion state, lead to detection Z-direction acceleration variable condition, by whether may determine that vehicle after calibration algorithm
In top dustpan road traveling, the top dustpan state of vehicle is sent to automobile chassis suspension, automobile chassis suspension passes through
The top dustpan degree of adjust automatically reduction vehicle.Simultaneously can also active control energy feedback dynamics reach reduction speed, make vehicle can be with
The road surface of safe out-of-flatness.
The entire car controller system of the utility model.The controller will lead to external sensor, vehicle signal tighter integration
Cross specific software and hardware method processing, the ability for making vehicle have intelligent control.FlexRay bus 1 has expanded the prior art
The communication modes of big bandwidth high speed have been introduced into entire car controller by communication interface, increase the real-time of data transmission,
Accuracy.Serious forgiveness is greatly improved.Millimetre-wave radar 3 increase to outside vehicle environment (nearby vehicle speed, safe distance,
Surface conditions etc.), the energy recovery rate of vehicle is promoted by the judgement to external signal, is reduced vehicle energy consumption, is promoted simultaneously
Vehicle safety in the process of moving and comfort.
The utility model can be used for the technical field of intelligent automobile full-vehicle control.
