Abstract
The utility model relates to a bus-based vehicle body control device. Control signals of the vehicle body control device are output to corresponding vehicle elements via a vehicle CAN (controller area network) bus, an LIN (local interconnect network) bus, a power cord, an earth wire and various input and output nodes. Data transmission and share among devices are realized by the buses, wire harness of a vehicle body is simplified, reliability of a system is improved, and automation level of the devices of the vehicle body is increased.
Description
Technical field
The utility model relates to electronic control device for vehicle, particularly relates to a kind of vehicle body control based on bus.
Background technology
Auto-industry are intensive capital, technology-intensive, the intensive industry of the talent, are to support China progressive backbone industry and important point of economic increase.Along with the widespread use of Eltec on automobile, vehicle electronics has become the important propelling thrust of automobile industry development.According to statistics, from 1989 to 2009, the ratio that on average the electronics installation cost accounts for whole auto cost on each car increased to 40% by 16%.On some Pullman saloons, nearly 90 of vehicle electronic control unit (ECU, Electronic Control Unit) quantity, the cost that accounts for car load has reached 50%.Therefore, the safety of the function of automobile ECU and performance and car load, reliability and traveling comfort are closely related.Vehicle body control is important automobile ECU, is directly connected to safety, the comfort feature of driving and the traveling comfort of taking.But existing body control system can't satisfy fast-developing automotive performance requirement.
Summary of the invention
Based on this, be necessary to provide a kind of vehicle body control based on bus.
A kind of vehicle body control based on bus, its control signal output to cooresponding automotive components through automobile CAN-bus, LIN bus, power lead and ground wire and each input and output node respectively.
In a preferred embodiment; Said input and output node comprise with operator platform switch, panel leds and remote control receiver module at least one major joint that links to each other; With at least one the instrument node that links to each other in instrument indicating device, text prompt module and the voice cue module; With at least one the left-hand door node that links to each other in left side anti-pinch automatic window, driven rearview mirrors and the electric control door lock; With at least one the right door node that links to each other in right side anti-pinch automatic window, driven rearview mirrors and the electric control door lock; With at least one front nodal point that links to each other in preceding lighting, loudspeaker and the wiper, and with back lighting, wiper, Reverse Sensor and tail-gate lock at least one posterior nodal point that links to each other.
In a preferred embodiment, said CAN bus links to each other with major joint.
In a preferred embodiment, said LIN bus, power lead and ground wire all link to each other with posterior nodal point with said major joint, instrument node, left-hand door node, right door node, front nodal point.
The vehicle body control based on bus of the utility model realizes equipment room through bus data transmission is simplified body harness with shared, improves system reliability and vehicle body equipment automatization level.
Description of drawings
Fig. 1 is the bus of vehicle body control among the embodiment and the circuit connection diagram of each node.
The specific embodiment
To combine specific embodiment and accompanying drawing that the vehicle body control of the utility model based on bus described in further detail below.
The vehicle body control of the utility model mainly comprises existing common circuit modules such as micro-control unit, power circuit, signal conditioning circuit, no longer these common circuit modules is given unnecessary details at this.Specifically, the vehicle body control of the utility model links to each other with each input and output node with ground wire through automobile CAN-bus, LIN bus, power lead, and each input and output node links to each other with each element of automobile again, transmission automobile each element state signal and control signal.Thereby the simplification body harness improves system reliability and vehicle body equipment automatization level.
As shown in Figure 1, above-mentioned input and output node comprises major joint, instrument node, left-hand door node, right door node, front nodal point and posterior nodal point.Wherein, major joint links to each other with the CAN bus.LIN bus, power lead and ground wire all link to each other with all nodes.
In major joint and operator platform switch, panel leds and the remote control receiver module at least one links to each other.In instrument node and instrument indicating device, text prompt module and the voice cue module at least one links to each other.In left-hand door node and left side anti-pinch automatic window, driven rearview mirrors and the electric control door lock at least one links to each other.In right door node and right side anti-pinch automatic window, driven rearview mirrors and the electric control door lock at least one links to each other.In front nodal point and preceding lighting, loudspeaker and the wiper at least one links to each other.In posterior nodal point and back lighting, wiper, Reverse Sensor and the tail-gate lock at least one links to each other.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
