Ono Sokki Co., Ltd. (President: Yuji Okoshi), a manufacturer and distributor of electronic measuring instruments, will launch its first-ever vehicle measurement data sales business. The first vehicle to be sold will be the "Yuan Plus" (known as the "ATTO3" in Japan), a mid-size SUV from BYD, China's largest EV manufacturer. The company plans to continue selling data from benchmark electric vehicles as needed.
Background of the sale
Currently, leading automakers around the world are fully committed to developing next-generation vehicles in order to realize a decarbonized society. In order to win this fierce development competition, the key factor is none other than benchmark data from competitors' vehicles.
Therefore, we have decided to fully utilize the measurement technology expertise we have cultivated in the automotive industry to measure electric vehicles, which are currently attracting a lot of attention, and to sell the resulting data. We are using our "Acoustics Lab. *1," which can evaluate NVH performance, and our "Automotive Testing Lab. *2," which can comprehensively evaluate power performance, while simultaneously conducting driving tests at the "JARI Shirosato Test Course." The resulting reports are unmatched by those of other companies.

| Test items | Overview and Selling Points | |
| JARI Shirosato Test Course | Motor and inverter vibration | We measured the vibration of the motor and inverter during steady-state and transient operation across the entire range from low to high load. Thirteen 3-axis accelerometers were comprehensively installed and used for measurement, and the results were compiled into vibration levels and contour maps. Characteristic patterns suggesting the intervention of control mechanisms were observed in different regions. |
| Motor inverter sound | Noise data measured simultaneously with the vibration data using six 1/2-inch microphones. The correlation between vibration and noise can be seen. | |
| Power unit mount vibration | We measured the vibrations at the inlet (component side) and outlet (body side) of the power unit mount. By capturing vibrations from three directions using a 3-axis accelerometer, we were able to determine the frequency characteristics input to the body from the mount characteristics. | |
| Car interior noise | Noise levels were measured in both the driver's and passenger's seats. Measurements were taken under a wide range of conditions, including steady-state driving, acceleration, acceleration/deceleration, creep driving, and starting from a stop. The level of quietness was high. | |
| Transmission system vibration characteristics | In addition to normal driving conditions, vibrations from the road surface are captured at the bottom and top of the steering wheel and seat when driving on harsh road surfaces, allowing for confirmation of seat vibration characteristics. | |
| Suspension and tire vibration | Vibrations transmitted from the road surface to the vehicle body were acquired using three-axis accelerometers attached to the lower and upper ends of the suspension. The relationship between the tire pattern and road noise could be inferred from the lower end, and the vibration characteristics transmitted to the body could be determined from the upper end. | |
| alarm bell | Noise levels of warning sounds compliant with the Road Transport Vehicle Act were measured on ISO road surfaces. | |
| Driving resistance | Driving resistance values obtained from coasting time measured on a test course in accordance with UN-GTR No. 15. Can be used as load data for mode-based energy consumption and real-world driving simulations on a test bench. | |
| Ono Sokki Lab | Fuel efficiency and driving range | Results of WLTP mode energy consumption and driving range tests. The 4WD-CHDY vehicle was used, and data was obtained under three ambient temperature levels: normal temperature, below freezing, and high temperature, as well as under conditions with the air conditioning on. The effectiveness of the vehicle's distinctive high-efficiency heat pump was confirmed. |
| Output characteristics | By using the RC-S *3, the drive shaft torque was directly measured with a shaft torque meter. The output characteristics for each drive mode (SPORT / NORMAL / ECO) and the maximum output relative to the State of Control (SOC) were measured. | |
| Power unit efficiency | Efficiency maps of the distinctive 8-in-1 unit were obtained on the RC-S across the entire range of rotational speed and load. A total of 129 points were measured, with power from a high-voltage battery as input and drive shaft output as output. | |
| Output limiting characteristics | Using RC-S, we continuously monitored the maximum power output and maximum speed for each drive mode and observed the situations in which power output limitations were imposed. | |
| Driving force characteristics | A robot was used to acquire the characteristics of the drive shaft output in relation to the accelerator opening for each drive mode. A total of 56 points were measured, from a standstill to maximum speed. | |
| Tip-out characteristics | The deceleration characteristics when the accelerator is tipped out were acquired for each vehicle regenerative braking mode (Standard/Hi). The deceleration and regenerative power were measured for each State of Charge (SOC), including a full charge. | |
| Regenerative characteristics | The amount of regenerative power and the behavior of the mechanical brakes were acquired when the brake pedal was operated using a robot. Since the drive shaft and DY are directly connected, measurements were taken without tire slippage. | |
| Tire rolling resistance | The rolling resistance and rolling resistance coefficient of individual tires were obtained in accordance with JIS D 4234. Measurements were taken simultaneously for both genuine tires for Chinese-spec vehicles and tires for domestically produced EVs. |
