Problems solved by technology
However, since the vehicle behind cannot distinguish whether the vehicle in front is braking in an emergency, the driver of the vehicle behind must subjectively judge the braking force of the vehicle in front according to the speed change of the vehicle in front, and then control the vehicle behind to perform corresponding braking. Braking has low accuracy. In bad weather such as rain, snow, thick fog, etc., it will be more difficult for the car behind to judge the braking situation of the front car in this way, which may easily cause accidents

Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.
[0031] figure 1 A schematic flow chart of an embodiment of a vehicle brake prompting method is shown in FIG.
[0032] The automobile brake prompting method comprises the following steps:
[0033] S102, obtaining the speed and acceleration of the car;
[0034] S104, judging whether the speed and the acceleration meet a preset emergency braking condition;
[0035] S106, if the emergency braking condition is met, control the exterior warning light of the vehicle to flash at a predetermined frequency.
[0036] By obtaining the speed and acceleration of the car, it is jud...

The invention provides an automobile brake promoting method and system and an automobile with the automobile brake promoting system. The method includes the steps that speed and accelerated speed of the automobile are obtained to judge whether a preset emergency brake condition is met or not; if yes, an outer warning lamp of the automobile is automatically controlled to flash at preset frequency to promote an automobile behind. A driver of the automobile behind can carry out corresponding disposal as soon as he catches sight of flash of the warning lamp without judging whether to brake emergently according to speed change of the automobile ahead, and rear-end collision accidents can be reduced.
Description
technical field [0001] The invention belongs to the technical field of vehicle braking control, and in particular relates to an automobile braking prompting method, an automobile braking prompting system and an automobile. Background technique [0002] In recent years, the road traffic safety situation has become more and more severe. According to statistics, among numerous traffic accidents, accidents caused by rear-end collisions account for the majority, especially rear-end collisions on expressways. However, rear-end collision accidents are mostly due to the fact that when the vehicle in front brakes urgently, the vehicle behind cannot quickly know and judge and deal with it in a timely manner. To ensure the safety of vehicles, yet there is no simple and efficient emergency vehicle braking prompt method so far. [0003] At present, when the vehicle is braking, it is generally adopted that the vehicle body controller BCM controls the high-mounted brake light and the norm...
