Modern automotive industry in the electronic part of the proportion of more and more high, many vehicle control, driving safety, communication interconnection and comfort equipment are inseparable from the powerful automotive electronic systems. Suitable for the automotive electronics industry applications of electronic test equipment has become an essential tool for automotive engineers.
ECU design and in-vehicle networks
With the use of a large number of electronic control unit ECUs, the communication and coordination between various control modules has become an important part of automotive electronic design. In addition to conventional protocol analyzers, engineers need a tool that can simultaneously observe the transmission protocols and analog signal waveforms of various sensors, and RIGOL's mainstream oscilloscopes, which can provide triggering and decoding functions for CAN and Flexray, are well suited for similar work. The instrument can not only convert complex waveform signals into data, but also perform specific triggering, such as capturing the bus state of the throttle position sensor at a specific angle and the changes of other signals at this time.
The size and timing of the ignition pulses are important for proper engine operation. Together with the high voltage probe, RIGOL oscilloscopes can capture the shape of the ignition pulse of each spark plug and precisely measure the time interval between them. Together with the current probe, the current output and fluctuation of the battery system can also be detected. Responding to the development of hybrid and pure electric vehicle technology, RIGOL's power analysis software can analyze the working status and loss of the drive module, helping engineers to modify the design and improve the drive efficiency.
Vehicle Excitation Signal Simulation
A large number of automotive sensors are capable of outputting signals of various amplitudes, frequencies and duty cycles to convey information about the vehicle's operating status, and RIGOL's Arbitrary Waveform Generator has built-in a wide range of arbitrary waveforms used in automotive electronics, which allows users to simulate changes in the sensors by adjusting the parameters of the signals and verifying the operating characteristics of the control circuits. In addition, RIGOL also provides the function of seamlessly outputting the waveforms captured by oscilloscope to the arbitrary waveform generator, which can perfectly simulate the various situations occurring under real road conditions.
data acquisition
Numerous parameters need to be monitored when the vehicle is running, such as water temperature, oil temperature, fuel pressure, battery voltage, interior temperature, etc. RIGOL's M300 data acquisition system is a good choice if multiple signal changes need to be detected for a long time. If you need to test the changes of multiple signals for a long period of time, RIGOL's M300 data acquisition system is a good choice.M300 has the testing capability of 6 ½-bit DMM, and it can test up to 320 channels on a single machine, which can complete the testing of voltage, current, resistance, frequency, cycle, temperature and other information. The Arbitrary Sensor function supports the conversion of various sensor outputs into data acquisition records that users are accustomed to.
Automotive RF Technology
There are many applications of RF technology in automotive electronics, including remote key/keyless entry system, tire pressure detection system (TPMS), reversing radar system, etc. RIGOL's RF signal source and spectrum analyzer is a cost-effective test solution for this kind of application. DSG3000 RF signal source supports common ASK/FSK modulation RF code output, together with the DSA series of spectrum analyzers, you can complete system testing from transmission to reception.
