Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is CAN/LIN bus transmission circuit figure mono-in the utility model;
Accompanying drawing 3 is CAN/LIN bus transmission circuit figure bis-in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
Embodiment of the present utility model: the method for designing of the distributed motor vehicle door arrangement of a kind of anticollision, the method adopts and arranges inductor at tail of the body, when vehicle stops preparing door opening, sensor is automatically opened measuring ability and is collected the mobile message being positioned at vehicle body mobile object below, and data are sent to control system, control system passes in and out Treatment Analysis to data and determines whether to control Vehicular door.
Wherein control system is ECU, the mode that this ECU realizes carrying out car door distributed AC servo system is the mixed network structure adopting CAN and LIN, namely the control signal of ECU is transmitted by CAN, control device on car door adopts distributed LIN web frame, connection between CAN and each car door adopts CAN-LIN gateway node to realize connecting and Signal transmissions, arrange in car warning lamp with buzzer and this warning lamp be connected with control system by CAN with buzzer, realize warning lamp and buzzer and opening/closing door of vehicle to carry out simultaneously, this inductor adopts ultrasonic sensing device, its detection range is the fan-shaped range of rear view of vehicle 15-25 °, detection maximum distance is 8-15m.
The distributed motor vehicle door arrangement of a kind of anticollision constructed by said method, as shown in drawings, comprise the control system ECU1 be arranged in car, at least 2 ultrasonic sensing devices 2 are symmetrical arranged at car body tail end, ultrasonic sensing device 2 is connected with control system ECU1 by data wire, the detection range of this ultrasonic sensing device 2 is the fan-shaped range of rear view of vehicle 15-25 °, detection maximum distance is 8-15m, vehicle window Controlling vertex 3 on each car door of car body, door lock Controlling vertex 4 and switch input control node 5 place arrange LIN node 6, above-mentioned LIN node 6 is in distributed network structure, total node of this LIN node 6 is connected by CAN 7 with between control system ECU1, total node of LIN node 6 adopts CAN-LIN gateway node 10 to be connected with CAN 7 junction, arrange in car warning lamp 8 with buzzer 9 and this warning lamp 8 be connected with control system ECU1 respectively by CAN 7 with buzzer 9, realize warning lamp 8 and buzzer 9 and opening/closing door of vehicle to carry out simultaneously.
During use, as shown in Figure 1, when the car is stopped, sensor group 2 opens measuring ability automatically, and the mobile object information 16 of inspection vehicle after one's death in setting range, when sensor group 2 collects the mobile message of mobile object, and is sent to ECU1 data, ECU1 processes according to the program of setting, CAN 7 is delivered to after the information such as the current location of rear object and speed being judged, if judge, mobile object and vehicle body distance are less than 1 meter, then send CAN control signal, realize left front door 12 car door lock and close (the vehicle window Controlling vertex 3 namely on car door, door lock Controlling vertex 4 and switch input control node 5 controlled), then all the other closing of the doors (i.e. left back car door 13 is controlled, right front car door 14 and right back car door 15, its controlled principle is consistent with left front car door), the buzzer 9 being simultaneously arranged in car 11 sounds, if now car door is opened, (the vehicle window Controlling vertex 3 namely on car door, door lock Controlling vertex 4 and switch input control node 5 are not controlled by releasing vehicle door lock for signal in CAN, by driver's Self-operating), in flicker car 11 car door early-warning lamp 8 and the buzzer 9 that sounds, report plays the effect of driver and front vehicle in alarm car.
Specifically, for left front door 12, CAN node adopts Freescale MC9S08DZ60 single-chip microcomputer as main control chip, CAN transceiver is integrated with the partial function of physical layer in CAN protocol, it adopts TJA1040 transceiver, each node is physically connected to CAN circuit by transceiver, and transceiver can drive the big current needed for CAN, and has the current protection to fault CAN or malfunctioning node; LIN is the low cost serial communication network of automotive development specially, usually used as the expansion of CAN network, for LIN node, due to the serial communication SCI module support LIN2.0 agreement of the MC9S08DZ60 chip that left front door node uses, can directly use MC9S08DZ60 as LIN master node control, as shown in Figure 3;
Device in each car door adopts distributed LIN web frame, each function is made independent node, namely independent rearview mirror control node, vehicle window Controlling vertex, door lock Controlling vertex, switch input control node, this switch input control node can simultaneously as the host node of LIN, the host node of each car door is CAN-LIN gateway node simultaneously, and ECU is connected by CAN net with four car doors; Secondly left front car door can obtain the state of other nodes in real time by the communication of LIN line, confirms actual condition.
Owing to being be based upon on the hybrid network of CAN and LIN to the control of whole car door dcs, being very easy to the transmission of the information that realizes and sharing, than traditional design, easily can provide more intelligent and function that is hommization.
