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.

Support for Various Measurements

Various transducers available for speed, angle, position, temperature, current, voltage, resistance, torque, etc.

Measuring Instruments and Signal Converters

■Outputs measurement data via CAN

■Simultaneous CAN and analog output (16bit) available

■Measurement is possible from 0 Hz

■Alarm signal can be output when the specified rotation speed or temperature is exceeded

Selection Point

Measuring instruments and signal converters

■Fastest 1ms update, CAN output

■Unique Periomatic^TM calculation (SPD), which is strong even at ultra-low rotational speeds. High accuracy from ultra-low speed to high speed. Follows sudden changes and sudden stops.

What is Periomatic^TM?は

■Various products such as rotational speed, angle, temperature, current, voltage, resistance, torque, CAN, etc.
