Problems solved by technology

Moreover, when the speed of the vehicle is high, the car radar may not even detect the vehicle ahead on the curve at all. If the driver drives the vehicle according to the signal detected by the car radar, it is easy to collide with the car in front or the obstacle ahead.

Embodiment Construction

[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] In the present invention, unless stated to the contrary, the used orientation words such as "front, rear, left, right" usually refer to the direction of the vehicle relative to the driver when the vehicle is running normally.

[0030] figure 2 It is a flowchart of a control method for a vehicle radar provided by an embodiment of the present invention. The vehicle-mounted radar is rotatably mounted on the vehicle through a driving device. Preferably, the vehicle radar can be installed at the front end and / or rear end of the vehicle through the driving device, such as figure 2 As shown, the control method includes the following steps.

[0031] Step S1...

Abstract

The invention discloses a control method, a control device and a system used for a vehicle-mounted radar. The vehicle-mounted radar is rotationally installed on a vehicle through a drive device. The control method includes the steps that a signal used for presenting the rotation angle of a steering wheel is received; according to the rotation angle of the steering wheel, a target angle of the vehicle-mounted radar is determined; according to the target angle of the vehicle-mounted radar, the drive device is controlled to work, and accordingly the vehicle-mounted radar rotates to the target angle. By means of the control method, a detection area of the vehicle-mounted radar is controlled according to the current rotation direction of the vehicle, so that the detection area of the vehicle-mounted radar adapts to the rotation direction of the vehicle. Thus, when the vehicle runs at a bend, the vehicle-mounted radar can flexibly and accurately detect the distance between the vehicle and a front vehicle or the distance between the vehicle and a rear vehicle or the distance between the vehicle and surrounding obstacles, and accordingly accidents are reduced.

Description

technical field [0001] The present invention relates to the field of automotive electronics, in particular to a control method, control device and system for vehicle radar. Background technique [0002] With the advancement of science and technology, various vehicle control systems are gradually developing in the direction of self-adaptation, and are becoming more and more intelligent. In the ACC system (Adaptive Radar Cruise Control) widely used at present, an on-vehicle radar installed at the front of the vehicle can detect the distance to the vehicle in front. The ACC system can automatically adjust the accelerator and brake according to the preset vehicle speed threshold and the distance to the vehicle in front detected by the vehicle radar, so as to maintain a safe distance from the vehicle in front and improve driving safety. [0003] However, when the vehicle is driving on a curved road, the area detected by the vehicle-mounted radar installed at the front of the veh...
