2.1 Basic terms

2.1.1 Advanced driver assistance systems; ADAS

The general term for the various systems that use the sensing, communication, decision-making and execution devices installed on the vehicle to monitor the driver, the vehicle and its driving environment in real time; and use information and/or motion control to assist the driver in performing driving tasks or actively avoid/mitigate collisions hazard.

2.2 Information assistance terms

2.2.1 Driver fatigue monitoring; DFM

Monitor the driver's status in real-time and send out prompts when confirming his fatigue.

2.2.2 Driver attention monitoring; DAM

Monitor the driver's status in real time and send out prompts when confirming that his attention is distracted.

2.2.3 Traffic signs recognition; TSR

Automatically recognize the traffic signs of the road section of the vehicle and send out prompts.

2.2.4 Intelligent speed limit information; ISLI

Automatically obtain the speed limit information that the vehicle shall comply with under vehicle appear at the side and/or behind the vehicle.

2.2.14 Blind spot detection; BSD

Monitor the driver's blind spot of vision in real-time, and send out prompts or warning when other road users appear in the blind spot.

2.2.15 Side blind spot detection; SBSD

Monitor the side and rear blind spots of the driver's field of vision in real-time, and send out prompts or warning when other road users appear in the blind spot.

2.2.16 Steering blind spot detection; STBSD

In the process of vehicle steering, monitor the driver's steering blind spot in real-time, and send out warning when other road users appear in the blind spot.

2.2.17 Rear cross traffic alert; RCTA

When the vehicle is reversing, monitor the other road users approaching the rear of the vehicle laterally in real-time, and send out alert when a collision risk may occur.

2.2.18 Front cross traffic alert; FCTA

When the vehicle is moving forward at a low speed, monitor other road users approaching the front of the vehicle in real-time, and issues alert when a collision risk may occur.

2.2.19 Door open warning; DOW

When the door is about to be opened in the parking state, monitor other road users on the side and behind the vehicle, and send out warning when the door is opened and there is a danger of collision.

2.2.20 Reversing condition assist; RCA

When the vehicle is reversing, monitor the environment behind the vehicle in real-time, and provides the driver with images or warning.

2.2.21 Maneuvering aid for low speed operation; MALSO

When the vehicle is running at low speed, detect the obstacles around it, and provide the driver with images or warning when the vehicle approaches the obstacle.

2.3 Control assistance terms

2.3.1 Advanced/automatic emergency braking; AEB

Monitor the driving environment in front of the vehicle in real-time, and automatically When the vehicle is parking, it automatically detects the parking space and provides the driver with parking instructions and/or direction control and other assistance functions.

2.3.10 Adaptive cruise control; ACC

Monitor the driving environment in front of the vehicle in real-time, and automatically adjust the driving speed within the set speed range to adapt to changes in the driving environment caused by the vehicle in front and/or road conditions.

2.3.11 Full speed range adaptive cruise control; FSRA

Monitor driving environment in front of the vehicle in real-time, automatically adjust the driving speed within the set speed range and have the functions of decelerating to stop and automatically starting from the stopped state to adapt to changes in the driving environment caused by the vehicle in front and/or road conditions.

2.3.12 Traffic jam assist; TJA

When the vehicle passes through the traffic jammed section at low speed, monitor the driving environment in front of the vehicle and the adjacent lane in real-time, and automatically control the vehicle horizontally and longitudinally. The use of some functions needs to be confirmed by the driver.

2.3.13 Anti-maloperation for accelerator pedal; AMAP

When the vehicle starts or is running at a low speed, if the driver accidentally steps on the accelerator pedal to cause emergency acceleration and may collide with surrounding obstacles, the vehicle is automatically restrained from accelerating.

2.3.14 Adaptive driving beam; ADB

The high beam that can automatically adjust the projection range to reduce the dazzle and interfere with the driver of vehicle in front or other vehicles.

2.3.15 Adaptive front light; AFL

The front light that can automatically switch between low beam and high beam or control the projection range, thereby providing different types of beams to adapt to various use environments of vehicles. […]
