Conventional automatic headlight devices determine whether to switch vehicle headlights on or off according to the brightness of the environment. These devices cannot automatically switch on headlights during daytime unless the headlights are required in specific road conditions (e.g. mountainous or foggy areas), thus compromising the safety of road users and drivers. This study develops a light-emitting...
Power lithium battery assembly production line adopts the distributed control system based on CAN bus, is divided into two levels, namely the station control layer( lower computer) and the production line management and control layer(IPC). Each station are connected to the CAN bus as a network node. In such multi-node and high load system, the standard CAN communication protocol can only ensure real-time...
The existing worst case response-time analysis for controller area network (CAN) with nodes implementing priority and First In First Out (FIFO) queues does not support mixed messages. It assumes that a message is queued for transmission either periodically or sporadically. However, a message can also be queued both periodically and sporadically using mixed transmission mode implemented by several...
This paper introduces the overall design of vehicle bus data acquisition and fault diagnosis system on the basis of OBD, focusing on its lower computer system and the upper computer system design principles. This system is based on the widely used CAN bus technology, to extract the vehicle's status or fault information. The CAN bus adopts the SAE J1939 protocol standards, maximize the superiority...
Recently, attentions are focused more on bus interior network application and the wireless bus-carry data transmission technology. For developing a remote monitoring system, three aspects of the system are discussed: the vehicle interior network configuration, the CAN/GPRS gateway realization and the remote monitoring server design. Described in the paper are the hardware and software design of the...
This paper propose a scheme of CAN-Bus universal interface module base on USB, The scheme uses USB chip CH375, CAN chip SJA1000, and uses MSP430F449 as control unit to complete USB, CAN interface control, as well as between the data processing and others. This paper also introduces software process and PC application program. In order to record the transmission time interval of the CAN information...

The purpose of this research is to invent a better method and system, which could eliminate the influencing variables caused by conventional method. All the variables will be constant except the kinds of additives which will be the main theme for comparison, through the retrieval of the signal such as speedometer, odometer, engine revolution and the signal from the electronic control unit (ECU) to...
The aim of this research is to develop an intelligent automated online forecasting of a car fuel consumption using neural network and classified it into classes of driving style. A new online monitoring tool was developed to acquire and analyze data collected from a car for the purpose of fuel consumption modelling and forecasting. The data was transmitted via ECU Can Bus attach to the car to the...
The dynamic, comfort and emission performances of vehicle directly dependent on the control of engine. Engine electronic control unit (ECU) receives the signals from the sensors, and gets the current engine status. Then depending on the signals, the ECU calculates fuel injection rate, injection timing and quantity. Accordingly the actuators which are driven by ECU carry out the better fuel control...
The controller area network (CAN) is a field bus that has been widely used in distributed embedded systems due to its inexpensiveness, robustness, guarantee of latency times as well as error detection. However, electromagnetic interference from the operational environment and hardware malfunction may cause short disturbances and permanent failures respectively, inevitably bring on communication errors...
