See Fig. 1, a kind of based on dividing the automobile intelligent of domain centralized calculation unit to drive calculating platform terminal, the terminal is by making With a high performance SOC processor and a high safety performance grade MCU processor, it is reconfigured at a series of being used for surrounding ring The sensor of border sensing, gathers peripheral vehicle barrier state, road condition, vehicle body transport condition in real time, carries out sensing data Analysis, decision-making calculate, and realize that FCW (frontal collisions early warning), LDW (lane departure warning), SVM (looking around imaging), AEB are (automatic Emergency brake), LKA (track keep auxiliary), ACC (adaptive cruise control), SAP (automatic parking auxiliary), 360 degree the work(such as look around Can, so as to fulfill intelligent driving.
The terminal include ARM computing units, HMI man-machine interaction units, before ADAS to camera, look around 360 cameras, super Sound radar, 77G millimetre-wave radars equipment, automobile control unit, braking system, dynamical system, steering, VCU.
To camera before ADAS:Before ADAS to camera be using Sony's superelevation sense cmos sensor and collocation image letter Number processor, can export high quality image signal, then can be realized in relatively long distance using the deserializer of a pair of U.S. letter The transmission of high speed, final image signal enter back into the arm processor of high performance SOC, carry out picture signal decoding process extraction The relevant information such as lane line and surrounding failure thing.
Look around 360 cameras:It is to export high quality image signal using OV10640 to look around 360 cameras, then using a pair The deserializer (MAX96705 and MAX9286) of U.S.'s letter can realize the transmission in relatively long distance high speed, so as to four The data of road GMSL serializers enter in MAX9286, and picture signal is inputted at the ARM of high performance SOC by CSI-2 passages Device, then the showing on the display screen 360 degree of surrounding environment by relevant algorithm are managed, so that driver is clearer Understanding automobile surrounding environment, safer parks.
Ultrasonic radar:Ultrasonic radar is that the MCU processors with high-performance safe class by way of LIN communications lead to Letter, ultrasonic radar produces the ultrasonic wave of 40KHz using the supersonic generator in sensor, then is received by receiving transducer through barrier Hinder the ultrasonic wave that thing reflects, the time difference received according to ultrasonic reflections calculates the distance between barrier.Automobile exists Parking stall and barrier persistently can be detected by sensor using 12 ultrasonic radars when parking, be automatically brought into operation steering wheel and braking Device, realizes automatic parking.
77G millimetre-wave radars:77G millimetre-wave radars are communicated by way of CAN communication with automobile control unit, main Point cloud/the obstacle information to be to provide, its information provided are that obstacle object point cloud is free with respect to six to radar its center The information of degree, i.e. positional information and yaw, inclination, pitch information.
HMI man-machine interaction units:HMI man-machine interaction units, which can be realized, to be shown the function of ADAS in display screen, can To realize the display for looking around 360 images, the switching of 360 image frames, and the switching of ADAS functions;
Automobile control unit:Automobile control unit controls the work of dynamical system, steering, braking system, VCU, together When receive dynamical system, steering, braking system, VCU operating condition signals, receive 77G millimetre-wave radars in signal, and will Signal inputs ARM computing units.
Dynamical system:Controlled by automobile control unit, drive motor racing.
Steering:Controlled by automobile control unit, drive motor turning.
Braking system:Controlled by automobile control unit, braking vehicle slows down.
VCU:Coherent signal is inputted into automobile control unit
Above structure, it is possible to achieve following functions
SVM (looks around imaging):When parking or low speed, by automobile, all around four-way CCD camera, synthesis automobile are got a bird's eye view Panoramic view picture, and be shown in automobile HMI man-machine interaction display screens, with monitoring of parking safely.SVM systems and ultrasonic radar data Fusion, more intuitively shows peripheral vehicle obstacle distance.
LDW (Lane Departure Warning System):Aid in driver to reduce automobile by way of alarm to send out because of deviation The system of raw traffic accident.When speed is on certain speed (such as 65km/h), system judges that vehicle is by forward sight camera No unconscious deviation fare, if it find that automobile is just in unconscious deviation fare, by display screen and alarm buzz come Remind driver.
AEB (automatic emergency brake):Using preposition radar and front camera, measure with front truck or barrier away from From, then using data analysis module by the distance measured and alarm distance, safe distance compared with, less than alarm apart from when With regard to carrying out alarm sounds, and when being less than safe distance, in the case that driver does not have enough time stepping on brake pedal, system Also it can start, make automobile automatic braking, so as to escort for safety trip.
FCW (frontal collisions early warning):By way of alarm, when there are driver is warned during potential risk of collision Accuse, for system by preposition radar and forward sight camera, moment monitoring front vehicles, judge the distance between this car and front truck, side Position and relative velocity, when there are during potential risk of collision, driver is reminded by display screen and alarm buzz to driver.
LKA (track keeps auxiliary):Pass through monitoring of the front camera to roadmarking so that vehicle is maintained at original Advance, be unlikely to because being produced across track dangerous in track.Judge that driver after run-off-road, gives such as in the case of unconscious Go out sound early warning, and control direction disk sails go back to former track.
ACC (adaptive cruise control):Front truck state is identified by preposition radar and front camera, and according to itself vehicle body State, calculates after judging, sends and instructs to actuator, to determine the transport condition of oneself, is acceleration or deceleration, still exits Cruise.Front truck can be followed to realize and be to maintain vehicle with car, its most basic function with car, parking, the adaptive cruise restarted Longitudinal driving, when there is risk of collision, vehicle can prompt driver and carry out active brake intervention.
SAP (automatic parking auxiliary):By the ultrasonic radar inductor of vehicle's surroundings, to detect vehicle in the process of parking In, size to the good vehicle of stop over, parking stall and calculated with the distance in roadside, so that by automatically controlling, will Vehicle drives into parking stall.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of changes, modification, replace And modification, the scope of the present invention is defined by the appended.
