What is the best choice for a driverless bus test tool?

Unmanned driving has gradually become a strategic commanding height for OEMs and Internet companies to invest in. Traditional car companies and the Internet are not only competing, but also integrating with each other. At the same time, in the process of networking and digitization, the demand for in-vehicle data recording is increasing. Trends can not only backup critical data, but also reduce and solve occasional failures!

Unmanned driving has gradually become a strategic commanding height for OEMs and Internet companies to invest in. Traditional car companies and the Internet are not only competing, but also integrating with each other. At the same time, in the process of networking and digitization, the demand for in-vehicle data recording is increasing. Trends can not only backup critical data, but also reduce and solve occasional failures!

As a traditional vehicle manufacturer, OEMs have mastered the core from vehicle design, vehicle testing, assembly, and manufacturing. They are system integrators with highly concentrated resources, while Internet companies are uniquely endowed with software, algorithms, and the Internet. The lightweight core is characterized by the concept of running with technology, so unmanned driving is the multi-dimensional data collection, fusion, processing and real-time control of the whole vehicle. The purpose is to free the driver’s hands and make the vehicle the concept of the next home.

data

For unmanned driving, data is the most important product, including vehicle sensors, vehicle communication and cloud communication data. Internet companies use artificial intelligence technology and use unmanned simulators to simulate the actual running conditions of the vehicle. It is to quickly realize the iteration of the algorithm, and the second is to save the time for real vehicle testing. At present, the country is also opening the road test of unmanned vehicles on designated road sections to accelerate the commercialization of unmanned vehicles in the implementation of unmanned vehicles. In the trial phase, ZLG also launched a CAN data recorder for this scenario to meet the data recording needs of multiple scenarios in the vehicle.

Application scenarios

According to the customer’s application scenario requirements, two types of products are launched: local data recording and data uploading server. The hardware interface includes two channels of CAN, one channel of Lin, and two channels of DI and DO as switch input and output, with built-in high precision The RTC clock ensures that the recorded data is highly synchronized with the actual bus transmission data.

The main differences are:

How data is transferred

Local data recording: manual SD card export data; remote data recording: 4G transmission, stored in the designated server, the data format has been opened for upload;

GPS track record

Only remote data recording supports real-time GPS track map recording;

In order to facilitate engineers to follow the test and enhance the versatility and ease of use of the product, the data recording product itself supports two-way USB to CAN real-time data transmission, and the product can be used as a two-way CAN card by logging in to ZCANpro (free host computer software). Use, real-time record CAN communication data of the whole vehicle, complete online data viewing and recording, approaching the new year, ZLG engineers developed new firmware based on CANDTU series products, opened the device Lin interface for real-time data viewing, upgrade the new firmware and download ZCANpro. Experience the Lin card function.

The latest ZCANpro software for high-level protocols also supports online DBC protocol analysis and curve drawing, and can view key parameters such as the current transmitter speed and hydraulic pressure of the vehicle in real time. The recorded data is converted into . ASC, CSV and other formats, compatible with mainstream analysis software, reduce the workload of engineers’ data analysis.
