What are the benefits of retrofitting a test bench for CAN compatibility?

By centralizing analog signals into CAN communication, the effects of noise inherent to analog wiring can be significantly reduced, improving data reliability. Additionally, because the number of wires can be reduced, it simplifies the system configuration and enhances maintainability.

How is support for driving actuators/robots implemented?

A feedback loop is established where the vehicle's speed and rotational data are provided as high-precision CAN data, and the robot operates the accelerator and brakes based on those signals. This enables 24-hour continuous testing and standardizes testing accuracy, making it independent of individual driving skills.

How is Periomatic technology utilized in test bench retrofitting?

With COCORESEARCH's proprietary Periomatic technology, high-speed tracking with 1-pulse response is achievable from ultra-low to high-speed ranges, even during sudden acceleration or deceleration. This supports the real-time, high-precision feedback control required by driving robots.

Modification of Vehicle Test Benches for CAN and Driving Robots

Renovate an existing test bench to support CAN and a driving robot.

Before: Old style test bench

Vehicle information was output via analog signals (speed, temperature, etc.)
→Difficulty in noise immunity

Driving operation by a skilled driver
→Difficult to test for long hours, different skills for each driver, secure highly skilled personnel

Large number of wires
→Large budget required for replacement

After: Example of modification

Convert vehicle information to CAN (speed, temperature, etc.)
→Improvement of noise immunity

Robot operates with signals fed back from PC
→Long-time testing is possible with less manpower, equalization of driving skills, and streamlining of testing.

Coco Research's transducers can be proposed from 50,000 yen per channel, price in Japan. Signal conversion for multiple channels is also available.
→Reduction of replacement cost is possible.

What this case study can do

Reduced wiring and noise immunity

Wiring from the test bed is changed to CAN (3-wire system) to reduce wiring and improve noise immunity.

Reduced manpower and improved reliability

No need for highly skilled operators, long-time testing is possible, and leveling of operating techniques improves test reliability and accuracy.

Low cost

Reasonable transducers reduce refurbishment costs, and operation robots reduce labor costs.
