And continuously circulating the steps.
Specifically, the early warning condition is set based on a preset vehicle distance or a safe vehicle distance, for example, when the vehicle speed v is greater than or equal to 100km/h, the safe vehicle distance between a rear vehicle and the vehicle should be controlled to be more than 100m (not including 100 m). For example, if the vehicle speed sensor of the vehicle detects that the actual vehicle speed v is greater than or equal to 100km/h, and the rear-view radar detects that the actual vehicle distance L between the rear vehicle and the vehicle is less than or equal to 100m, the actual vehicle distance is less than the safe vehicle distance, and at this time, if the early warning condition is set that the vehicle speed v is greater than or equal to 100km/h and the vehicle distance L between the rear vehicle and the vehicle is less than or equal to 100m, the above example meets the early warning condition, the early warning function is activated, an interactive early warning image is generated, and the interactive early warning image is displayed on the signal lamp at the tail part of the vehicle, as shown in fig. 5-9, the warning information such as ' keeping the vehicle distance ' and slow down ' is transmitted to the rear-coming vehicle image text, the graphic warning with characters has definite meaning, so that the understanding ambiguity caused by the cognitive deviation of the rear-vehicle driver can be effectively avoided, and, the risk of collision of the two vehicles is killed in the bud state, the driving safety is greatly enhanced, and the active safety performance of the vehicles is improved.
The early warning condition is changed along with the change of the actual speed v of the vehicle, for example, when v is more than or equal to 80km/h, the safe distance between the rear vehicle and the vehicle should be controlled to be more than 80m, at this time, the early warning condition can be set to be that the speed v of the vehicle is more than or equal to 80km/h and the distance L between the rear vehicle and the vehicle is less than or equal to 80 m. By analogy, different early warning conditions can be preset according to different vehicle speeds, so that safety early warning can be effectively provided under different driving states. The early warning conditions can be pre-stored in the interactive control unit in two parts, wherein the first part is the speed of the vehicle, the second part is the safe distance, the corresponding early warning conditions can be called according to the comparison result of the actually measured speed v and the first part, if the actually measured speed of the vehicle is 100km/h, the early warning condition with the speed v of the vehicle being more than or equal to 100km/h is correspondingly called in the first part, the distance L between the rear vehicle and the vehicle is less than or equal to 100m in the second part of the early warning conditions, if the actual distance L between the rear vehicle and the vehicle is less than or equal to 100m, the early warning conditions are fallen into, so that the early warning function is activated, and if the actual distance L between the rear vehicle and the vehicle is more than 100m, the early warning conditions are not fallen into and the early warning function is not activated.
The vehicle provided with the rear vehicle collision prevention interactive early warning system has higher active safety obviously than a vehicle only provided with a traditional signal lamp, the early warning system and the traditional signal lamp can be integrated, the whole volume of the signal lamp cannot be increased, and the active safety function is improved greatly.
