ROTOTEST CHASSIS DYNAMOMETERSNew Paradigm for “Road Load Simulation Testing”

MINIMUM INFRASTRUCTURE REQUIREMENTSCompared with conventional roller-type chassis dynamometers (CDM), the ROTOTEST Energy system (figure 4a) does not require a large facility such as an underground pit. With a level floor plan (e.g. garage) and power (@400V, 3 phase) being the main requirements, a full battery of tests can be carried out. This dramatically lowers cost and provides flexibility. Please note that additional equipment may be needed to support the ROTOTEST test environment. This includes (but not limited to) cooling and exhaust infrastructure.

MEASUREMENT SYSTEM WITH HIGH ACCURACY AND REPEATABILITY When it comes to conventional roller-type chassis dynamometers, measuring torque directly in the hub position brings many advantages including high accuracy and constant repeatability. With no interference from the automobile’s tires, this system achieves high repeatability, which is important for performing benchmark testing. In addition, this unit can be automatically tilted in order to adjust the torque measurement line.

SUPPORT FOR ELECTRIC AND HYBRID VEHICLESIn addition to supporting automobiles with a gas combustible engine, Rototest dynamometers also support newer electric and hybrid vehicles.

PERFORM AND VALIDATE EPA CERTIFICATION REQUIREMENTS Rototest Dynamometers support EPA driving cycles such as FTP and US06. And the requirements for tolerances and response are also supported. Furthermore, the solution can be used for certification testing according to Federal Regulation 40 CFR Part 86 Section 86.108.

STEERING OPERATION CAPABILITY Due to its unique structure, ROTOTEST Energy provides a bench test with steering operations. This is something not typically achievable with conventional CDM. The steering angle can be rotated to +/- 20 degrees (see figure 5b). You can simulate driving situations including steering operation, evaluate for ADAS, autonomous car, etc.

This system can be used in a climate chamber. The EV performance can be used in very low temperature environments to evaluate how such vehicles respond in such conditions.

ROTOTEST NVH Model

LOW NOISE MODEL FOR NOISE AND VIBRATION TESTROTOTEST Energy NVH can be customized by removing blowers for cooling and covering the blowers with sound insulation boxes. The model can also be installed in semi-anechoic chambers.

ROTOTEST StandardModel

500KW 4WD MODEL FOR ROAD LOAD SIMULATION ROTOTEST Energy 500 4WD each consists of 500kW on each dynamometer axle. It can be used on 4WD and 2WD. Because of its repeatability, accurate results can be obtained from the benchmark test. Several power models are available depending on your specified requirements.

NOISE & VIBRATION TESTEven very low noise levels can negatively impact NVH measurements. Compared with traditional roller type dynamometers, there is next to no tire noise generated by the ROTOTEST units.

In partnership with Iwane, TOYO Corporation engineered the Real Video Drive Player (RVDP), a powerful and unique driving simulator (see figure 6a). It is one of the few professional simulators that incorporates and uses actual road videos (that you per-record ahead of time) (figure 6b) providing a simulation experience that comes very close to actually driving on a real road except it all takes place inside a lab (see figure 6c).

The RVDP has many important capabilities. One key feature is the roving viewpoint. You only need to record a video just once but it is possible to simulate lane changes, turns, height positions and seat positions and have those changes automatically adjusted for. Up to 360 degrees of simulation environment is available on demand.

The RVDP helps reduce the cost and delays associated with automobile development.

MIMO OTA | EVALUATION OF V2X COMMUNICATIONAs typified by the word “connected car”, various functions have come to be realized by the wireless communication of cars. In the concept of Intelligent Transport System (ITS), two wireless communications are assumed. The first is “V2V” (inter-vehicle communication) in which vehicles exchange information by wireless communication at intersections with poor visibility. The second is “V2I” (road-to-vehicle communication), which transmits infrastructure information from a roadside device to a vehicle via wireless communication using radio waves. Information from the infrastructure includes traffic light information, regulatory information, pedestrian information, etc. V2x technology has been developed to support safe driving. By using Multiple Input Multiple Output (MIMO) technology, communication capacity can be increased (multi-stream transmission) and communication errors can be reduced (single stream redundant transmission). Wireless equipment using MIMO technology that allows multiple antennas to transmit and receive communications to form multiple independent propagation paths will be implemented in vehicles from now on. Evaluation of communication quality is extremely important to secure communication performance, and demand is increasing. In particular, when implementing a wireless device intended for autonomous driving, it is necessary to guarantee absolute communication performance in order to directly connect for safety. However, when evaluating the performance of in-vehicle wireless devices, it is not possible to ignore the interference from large metal bodies and other electronic devices mounted in the vehicle. For vehicles equipped with wireless equipment using MIMO technology, it is necessary to evaluate a MIMO OTA (Over The Air) test to evaluate throughput performance (transmission capacity of communication data) by the MIMO function.

RADIATED TWO-STAGE METHOD MIMO OTA MEASUREMENTConnecting and evaluating performance via an antenna of a wireless device is called OTA performance test, but there are several methods for this test. These include the multi-probe method, the reverberation chamber method, and the two-stage method (Conducted Two Stage: CTS method). In the case of the most common multi-probe method, the measurement system is large to accommodate the size of the vehicle and the cost is correspondingly high. Therefore, General Test Systems (GTS) proposes a new automotive MIMO OTA measurement solution that can reduce costs by applying its own-developed Radiated Two Stage (RTS) method to automotive MIMO OTA testing. The RTS method is one of the two-stage methods that improves the CTS method, and is a method that solves the problems while keeping all the advantages of the CTS method. It was proposed by GTS to 3GPP, a standardization body, and was newly added to the standard (TS 37.544 v14.5.0 (2018-03)) in March 2018.

Stage 1: Test the radiation characteristics of multiple antenna branches in a conventional common anechoic chamber. The measurement system must perform a complete three-dimensional antenna pattern measurement for both transmitting and receiving radiation performance and measure two orthogonal linear polarization components (generally θ polarization and φ polarization) . Measure the amplitude and relative phase of the antenna of the DUT to measure antenna patterns independent of each other.

Stage 2: The antenna pattern measured in the first stage is combined with the MIMO propagation channel model. Furthermore, the inverse matrix of the portion corresponding to the RF space from the measurement antenna in the anechoic chamber to the measurement space and the antenna of the DUT is calculated, and a test signal is generated to cancel this RF characteristic. With the DUT fixed in an anechoic chamber (both position and orientation with respect to the transmit antenna), the MIMO channel model is emulated by the channel emulator, and signals are supplied to the transmit antenna to perform a MIMO throughput test.

In a 2 × 2 MIMO throughput test configuration, the horizontal and vertical polarization of one measurement antenna can be used as two independent measurement antennas. By transmitting the test signal through space rather than the RF cable, the antenna of the DUT remains connected, and the MIMO throughput can be measured without interruption to assess the effects of desensitization and self-interference. Because there is no cable connection to the DUT in the second stage, the DUT can be measured as it is located in an anechoic chamber, unaffected by the entire test.

SOURCE RECONSTRUCTION METHOD NEAR FIELD TO FAR FIELD CONVERSIONWhen measuring antenna radiation patterns, it is common to place the antenna of the DUT at the center of rotation of the turntable. However, because the size of the car is large, even if the anechoic chamber equipped with a turntable with a diameter of 6 m, if the antenna is located at the end of the vehicle, it cannot be placed at the center of rotation. In addition, the vehicle height is different between the car and the one box. For this reason, if an antenna is installed on the roof, a lifting function is required. Without the gantry (or arch) lift mechanism used for 3D radiation pattern measurement, it can not be aligned with the elevation center of rotation. In radiation pattern measurement, the premise is that the wave source is at the center of rotation, and the misalignment of these installation positions is a major error factor. The spherical near-field far-field conversion software of the “source reconstruction” method provided by GTS has a function to correct the position of the wave source of the antenna, so it is possible to correct such a positional deviation to obtain an accurate far-field radiation pattern data.

SOURCE RECONSTRUCTION METHOD NEAR FIELD TO FAR FIELD CONVERSIONIn order to obtain sufficient transmission performance of MIMO, it is important to obtain multiple independent propagation paths. No matter how good the performance of a single antenna is, independent propagation paths cannot be obtained if similar signals are received from each antenna. In other words, the correlation coefficient, which is the characteristic between antenna branches, is important. The lower the correlation, the more independent the signal is being received. In addition, if antenna elements are close to each other, they will be mutually affected (coupling) and the efficiency of the antenna will be reduced. The antenna requirements of MIMO require more consideration of the location of each branch and the surrounding environment than the performance of a single unit. In the past, antenna evaluation used to measure the radiation pattern and gain of an antenna in an anechoic chamber that simulates a free space without reflected waves. So what kind of evaluation should we use when using multiple antennas? Whether it is reception diversity or MIMO, it is an antenna system that assumes operation in a multi-path environment where reflected waves exist, so an environment close to that is desirable. In a propagation path where there are no direct waves and the number of reflected incoming waves is large, the I and Q components of the complex received signal have a normal distribution (amplitude fluctuation and phase fluctuation are random). At this time, the amplitude of the received signal has a Rayleigh distribution, which is considered to be an environment created by the synthesis of many scattered waves with almost equal levels. If you place the antenna in a Rayleigh-distributed fading environment and observe the reception level for a sufficient time, the reception level will be low (fading dip) with a certain probability. By graphing and comparing the cumulative probability distribution of the reception level data, it is possible to quantitatively evaluate how much the reception level is improved. By measuring the same set of antennas in different arrangements, the effectiveness of diversity can be evaluated. In other words, even if the performance of a single antenna is the same, the diversity effect greatly changes depending on the placement. This means that in a multi-antenna system, the implementation of the antenna element greatly affects the reception performance.
