ECU design and in-car network

With the use of a large number of electronic control unit (ECU), the communication and coordination between the control modules are becoming an important part of automotive electronic design. In addition to the conventional protocol analyzer, the engineer needs a tool that can simulate signal waveforms at the same time as the transmission protocol and various sensors. RIGOL’s mainstream oscilloscope can provide CAN and Flexray trigger and decoding functions, can be a good way to complete a similar work. The instrument can not only be able to transform the complex waveform signal into data, but also can perform the specific trigger, such as the acquisition of the position sensor at a certain point of view, the change of the state of the bus at the time when the other is different from each other.

Drive system

The size and timing of the ignition pulse are important for the normal operation of the engine. With the high pressure probe, the RIGOL oscilloscope can capture the shape of the ignition pulse of each spark plug, and measure the time interval between them. With current probe, the current output and fluctuation of battery system can be detected. To deal with the development of hybrid and pure electric vehicle technology, RIGOL power analysis software can analyze the driving module and the working state and the loss of the situation, to help engineers to modify the design, improve the driving efficiency.

Vehicle excitation signal simulation

A large number of vehicles with sensors to output a variety of amplitude, frequency and duty cycle of the signal to change the vehicle operating status information. RIGOL arbitrary waveform generator with a large number of motor vehicles in the use of arbitrary waveform, the user can adjust the signal parameters, analog sensor changes, verify the performance of the control circuit. In addition, RIGOL also provides the oscilloscope capture waveform to the seamless output to any waveform generator function, can be perfect simulation of the actual conditions of the situation.

Data acquisition

When the vehicle is running, a number of parameters need to be monitored, such as water temperature, oil temperature, oil pressure, battery voltage, temperature inside the car. RIGOL’s M300 data acquisition system is a good choice if you need a long time to detect multiple signals. M300 has 6.5 digits DMM test capability, single unit can test up to 320 channels, can complete the voltage, current, resistance, frequency, cycle, temperature, etc. Any sensor function can support a variety of sensor output into user habits of data acquisition and record.

Data acquisition

Vehicle radio frequency technology

Many radio frequency technology is used in the automotive electronics, including remote control key / no key entry system, tire pressure detection system (TPMS), reverse radar system, etc. RIGOL RF signal generator and spectrum analyzer is the high performance ratio test scheme for this kind of application. DSG3000 RF signal source supports common ASK/FSK modulation of the RF code type output, with the DSA series spectrum analyzer, you can complete the system test from the transmitter to the receiver.
