Embodiment 1

[0080] Embodiment 1: Realization and control of the high beam function of vehicle headlights

[0081] 1 Analyze the composition of the subsystem Headlight high beam light bulb + headlight controller (located inside the headlight, shared with the low beam, position light, turn signal and electric horn in the headlight) + connecting wire (one J01 signal line, one GDN ground line, one B + Power supply) + connector of headlight and main system (unified 3-port connector) + main controller (common part of VIT system, located in instrument) + control mechanism (located on combination switch, common with traditional system) +Power system (shared by the whole system)

[0082] 2 Analyze the function and power load of the subsystem. The bulb power of the high beam of the headlight is 70W*2 (because the vehicle has two high beams, one on the left and one on the left), and the load of this subsystem is registered in the power load list of the whole system.

[0083] 3 Determine the execut...

Embodiment 2

[0090] Example 2: Design and Implementation of Charging Indication System

[0091] 1 Analyze the composition of the subsystem Generator D+terminal+connector+main controller+connecting wire+instrument indicator system

[0092] 2 Analytical logic function Excite the generator + indicate the working status of the generator through the instrument

[0093] 3 Design the indication condition and indication circuit, and calculate the system capacity as 500mA

[0094] Such as image 3 As shown, the design circuit diagram of the charging indication control circuit:

[0095] The excitation current of the alternator is provided by the 24V port, which is controlled by the ON position of the key door, and the alarm voltage is set by the clamp diode. System alarm.

[0096] 4. Determine the capacity of the control circuit. After calculation, choose 0.5mm2 polyvinyl chloride thin-walled wire, and the standard is VW 603 06.

[0097] 5 Determine the connector model According to the plan, th...

Embodiment 3

[0100] Implementation 3: Realization and control of low beam function of vehicle headlights

[0101] 1 Analyze the composition of the subsystem Headlight low beam light bulb + headlight controller (located inside the headlight, shared with the high beam, position light, turn signal and electric horn in the headlight) + connecting wire (one control wire, one ground wire, one live wire) + the connector between the headlight and the main system (a unified 3-port connector) + the main controller (a common part of the VIT system, located in the instrument) + the control mechanism ( Located on the combination switch, common to the traditional system) + power supply system (shared by the whole system)

[0102] 2 Analyze the function and power load of the subsystem. The bulb power of the low beam of the headlight is 70W*2 (because the vehicle has two high beams, one on the left and one on the left), and the load of this subsystem is registered in the power load list of the whole syste...

Abstract

The invention relates to a VIT hardware cording communication bus control system of a commercial vehicle. The VIT hardware cording communication bus control system of the commercial vehicle is characterized in that: firstly, a communication control part defines three kernel logic modules, namely an encoder, a decoder and a pulse shaft by adopting VIT technology, a V-axis, an I-axis and a T-axis are used for representing voltage, current and time respectively, and the encoder is positioned in a main control mechanism on a dashboard of a vehicle and the decoder is positioned in each electric measuring and executing part and belongs to universal modules; and secondly, corresponding address codes are configured and distributed to all the electric functions of the vehicle by resolving and planning the pulse axis, which means one code corresponds to one specific electric function. The communication of the system bus has the characteristics that: each frame data comprise the state information of all the electric functions inside; and due to a uniform interface, the design of the vehicle electric system is universalized and modularized, the design and maintenance difficulties are reduced, the workload is greatly reduced and the development cycle is shortened, so that a great number of design and after-sale maintenance personnel can be cut and the cost is reduced. Thus, the revolutionary progress is expected to be brought to the electric system design and maintenance in the vehicle industry.

Description

Technical field: [0001] The invention relates to a commercial vehicle VIT hardware coding communication bus control system, which is the application of the VIT three-axis multi-value covariant space three-dimensional coding communication technology in the electrical system of the commercial vehicle. Background technique: [0002] With the development of commercial vehicles in the direction of sedans, the on-board electrical systems are gradually increasing. The existing principles and structures have caused serious bottlenecks in the development of electrical systems. Non-renewable raw materials, and the cost has increased sharply, and the maintainability and safety of the system have also been severely challenged. Invention content: [0003] The purpose of the present invention is to provide a commercial vehicle VIT hardware coding communication bus control system. The electrical system of the whole vehicle adopts the VIT three-axis multi-value covariant space three-dimen...
