Embodiment Construction

[0028] figure 1 is a schematic flowchart of an automatic emergency braking method according to an embodiment of the present invention. Such as figure 1 As shown, the automatic emergency braking method provided by an embodiment of the present invention includes the following steps:

[0029] Step S101: sending a first deceleration request at a first rate;

[0030] Step S102: Realize automatic emergency braking according to the above-mentioned first deceleration request.

[0031] In the prior art, when the automatic emergency braking system is triggered, the automatic emergency braking system directly sends out a step-type deceleration request, causing the vehicle to generate a huge deceleration in an instant, up to 8m / s in an instant 2 , and the huge deceleration will cause extremely uncomfortable feeling to the occupants in the car, and may even cause injury accidents; while the embodiment of the present invention sends the deceleration request of the first rate when the aut...

Abstract

The invention provides an automatic emergency brake method and device. The automatic emergency brake method comprises the following steps of transmitting a first deceleration request of a first rate; and realizing automatic emergency brake according to the first deceleration request. According to the embodiment of the invention, when the automatic emergency brake is triggered, the deceleration request of the first rate is transmitted, so that the deceleration is gradually increased from zero, people in a vehicle can be reminded that an automatic emergency brake system is started, and fright caused by the sudden deceleration of the vehicle is reduced; A buffer process is achieved in the early stage of the vehicle deceleration, so that the comfortability of people in the vehicle can be effectively improved in the process that the automatic emergency brake is triggered, and the automatic emergency brake becomes a comfortable and safe active safety function.

Description

technical field [0001] The invention relates to the field of vehicle emergency braking, in particular to an automatic emergency braking method and device. Background technique [0002] Automatic emergency braking is an active safety system that can automatically brake the vehicle to avoid or slow down the collision when there is a potential collision dangerous vehicle on the path ahead of the vehicle. It can actively avoid accidents, so automatic emergency braking systems have become more and more widely used. [0003] The automatic emergency braking system is mainly composed of a ranging module, a control module and a braking module. The ranging module can be an environmental sensor, microwave radar, millimeter wave radar, laser radar or video system, etc., to provide comprehensive and accurate information on the road ahead. , Real-time image and road condition information to detect the distance and relative speed of the vehicle in front or obstacle and the vehicle, and th...
