Abstract

The invention belongs to the technical field of automobiles, and particularly relates to a steering wheel follow-up millimeter-wave radar. The radar comprises a corner sensor, a follow-up controller,a stepping motor, a connecting rod and a millimeter-wave radar body. The corner sensor is mounted at the lower end of a steering wheel; the follow-up controller is mounted in an instrument board; thestepping motor is mounted on a front bumper; the millimeter-wave radar body is mounted on a bumper bracket; the corner sensor is connected with the follow-up controller; the follow-up controller is connected with the stepping motor; an output shaft of the stepping motor is meshed with the connecting rod; one end of the connecting rod is in sliding fit with a sliding groove of a shell of the stepping motor, and the other end is connected with a shell hook of the millimeter-wave radar body through a ball head. According to the millimeter wave radar, follow-up steering of the millimeter wave radar in the curve self-adaptive cruise process can be achieved, the accuracy of target recognition is improved, safety and reliability are achieved, and the problems that an existing millimeter wave radar is delayed in response, mistakenly recognizes a target object of an adjacent lane and causes emergency braking are solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a steering wheel-following millimeter-wave radar. Background technique [0002] With the advancement of technology and the development of society, cars have been widely used, and more and more cars are equipped with adaptive cruise control (ACC), in which target recognition mainly relies on millimeter waves installed on both sides of the front bumper radar. Conventional millimeter-wave radar has the following problems: [0003] When the vehicle is cornering, the ACC function may misidentify the target in the adjacent lane due to the delay of the millimeter-wave radar response, causing emergency braking. [0004] Therefore, how to develop a millimeter-wave radar that can follow the steering control has become an urgent problem to be solved. Contents of the invention [0005] The present invention provides a steering wheel follow-up millimeter-wave radar with a...
