Problems solved by technology

[0004] However, when the external environmental factors such as light and weather are poor, or when the lane lines are worn and polluted seriously, or when the lane lines are blocked by some objects, the quality of the vision sensor's recognition of the lane lines will be reduced, causing the ECU to Wrong control of the lateral state of the body, affecting driving safety

Embodiment Construction

[0061] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0062] Existing lane keeping technology is realized based on visual sensors (such as vehicle-mounted cameras). When an object is blocked, the recognition quality of the lane line by the visual sensor will be reduced, causing the ECU to incorrectly control the lateral state of the vehicle body, affecting driving safety. .

[0063] In the embodiment of the present invention, a corresponding improvement solution is provided for the a...

Abstract

The invention discloses a body transverse control method and an electronic control unit (ECU). The ECU comprises a forward millimeter-wave radar, a road boundary recognition module and a body transverse control module, wherein the road boundary recognition module acquires parameters of at least one target object from the forward millimeter-wave radar, a boundary target object is determined from the at least one target objects according to the parameters of the at least one target object, boundary curve parameters and boundary curve quality corresponding to the current moment are determined according to the boundary target object, and the boundary curve parameters and the boundary curve quality corresponding to the current moment are input into the body transverse control module so that the body transverse control module can perform transverse control on a body according to the boundary curve parameters and the boundary curve quality corresponding to the current moment. The ECU performs transverse control on the body based on the parameters of the at least one target object acquired by the forward millimeter-wave radar; and compared with control based on a vision sensor, the influence of external environment factors is small, and it is guaranteed that the transverse control of the body by the ECU is more accurate.

Description

technical field [0001] The invention relates to the technical field of intelligent driving, and more specifically, relates to a vehicle body lateral control method and an electronic control unit ECU. Background technique [0002] Advanced Driving Assistant System (Advanced Driving Assistant System), also known as intelligent driving system, uses various sensors installed on the car to sense the surrounding environment at any time during the driving process of the car, collect data, and detect static and dynamic objects. The identification, detection and tracking of the system, combined with the map data of the navigator, is used for systematic calculation and analysis, so that the driver can be aware of possible dangers in advance, and the comfort and safety of car driving can be effectively increased. As an important part of the intelligent driving system, lane keeping technology can prevent traffic accidents caused by driver fatigue or distraction. [0003] The existing l...
