Evaluation of five major systems: ACC, AEB, LDW, BSD, and APS

On February 6, 2018, China Automotive Engineering Research Institute (hereinafter referred to as “China Automotive Research”) issued a draft of the “China Smart Vehicle Index Evaluation Regulations” (hereinafter referred to as “Procedures”) in Chongqing, from February 6 The system will be consulted on February 28th, and the official version will be released in March, and the test evaluation of the models on the market will be launched.

The “China Automotive Research” program will evaluate more than 25 production models in 2018. The evaluation results will be released on the official website of i-VISTA.

Considering the differences in the functions of ADAS in various vehicle companies, the China Smart Car Index first targets adaptive cruise (ACC), automatic emergency braking (AEB), lane departure warning (LDW), blind zone monitoring (BSD), and automatic parking. Auxiliary (APS) has a total of five systems for independent evaluation, and then gradually transition to the overall evaluation of ADAS products. In the future, the evaluation system will be dynamically updated according to the actual mass production of L2, L3, L4, L5 and other automatic driving technologies. In terms of dimensions, ADAS only evaluates the two dimensions of safety and experience; L2 and L3 autopilot safety evaluates the three dimensions of safety, experience and energy consumption; L4 and L5 autopilot for safety, experience, energy consumption and efficiency Evaluation of dimensions. Evaluation of five major systems: ACC, AEB, LDW, BSD, and APS

The ACC test evaluation procedure mainly refers to the ISO 22179 "Intelligent Transport Systems-Full Speed ​​Range Adaptive Cruise Control (FSRA) Systems-Performance Requirements and Test Procedures" standard. The test conditions include the target vehicle stationary, the target vehicle low speed, the target vehicle deceleration, the stable following, the curve deceleration, and the full acceleration. The ACC performance is evaluated. During the test, data such as the target vehicle speed, the main vehicle speed, the target vehicle acceleration, the main vehicle acceleration, the longitudinal distance of the two vehicles, and the lateral distance of the two vehicles are collected.

The AEB test evaluation procedure mainly refers to IIHS "Autonomous Emergency Braking Test Protocol" Version 1 and other standard regulations and test items. Test conditions are divided into two dimensions: safety and experience. Among them, the safety evaluation is divided into FCW function test and AEB function test, including three types of test conditions: target vehicle static, target vehicle low speed and target vehicle deceleration. The experience evaluation is divided into AEB system action strategy, human-computer interaction and false alarm evaluation.

The LDW test evaluation procedure refers to GB/T 26773-2011 "Intelligent Transportation System Lane Departure Alarm System Performance Requirements and Detection Method" standard, Euro NCAP "Test Protocol-Lane Support Systems" Version 1.0 November 2015 standard and J2808 2007 SAE "Road/Lane" Departure Warning Systems: Information for the Human Interface standard, the safety evaluation consists of two test cases: the straight line dashed repeatable alarm and the curved line dotted line alarm. The experience evaluation mainly includes human-computer interaction and different types of lane line recognition capabilities.

The BSD test evaluation procedure mainly participates in the ISO 17387 "Intelligent Transport Systems-Lane Change Decesion Aid Systems (LCDAS)-Performance Requirements and Test Procedures" standard. Among them, the safety evaluation condition is that the target vehicle straightly exceeds the main vehicle, the main vehicle speed is 60km/h, and the target vehicle exceeds the main vehicle at 70, 80, 90, 100, 110, 120km/h, and the alarm of the BSD system is tested. performance. The experience evaluation mainly includes human-computer interaction and China's unique two-wheeler recognition ability.

The APS test evaluation procedure refers to the ISO 16787 "Intelligent Transport Systems-Assisted Parking Systems (APS)-Performance Requirements and Test Procedures" standard, in which the experience evaluation is divided into a parking space search ability test and a parking capacity test, and the safety evaluation is performed from the vehicle obstacle detection with pedestrians. Two aspects of obstacle detection were tested. In addition, the additional item is a parallel parking space parking function.

Absolute Encoder

Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
