The invention provides an automobile speed limiting and safe automobile distance control system and method, and relates to the technical field of automobile control. Comprising a controller used for judging whether the distance between a vehicle and a front vehicle is too close or not, and if yes, a speed reduction instruction is sent to a vehicle speed control device; whether the distance between the vehicle and the rear vehicle is too close in the speed reduction process or whether the distance between the vehicle and the front vehicle is still too close in the process of reducing the vehicle speed to a set value is judged, and when at least one is met, a reminding signal is sent to remind a driver to stop speed reduction and change lanes; and the vehicle speed control device is used for receiving the speed reduction instruction and carrying out speed reduction operation. According to the method, the safety distance between the vehicle and the front vehicle, the road environment and the safety distance between the vehicle and the rear vehicle are comprehensively considered, when it is detected that the vehicle is too close to the front vehicle, speed reduction processing is conducted firstly, and when the speed is reduced to a set value and then is still too close to the front vehicle or it is detected that the vehicle is too close to the rear vehicle in the speed reduction process, speed reduction processing is conducted. And at the moment, the driver is reminded to stop decelerating and change lanes.

    本发明提出汽车限速和安全车距控制系统及方法,涉及汽车控制技术领域。包括控制器,用于判断自身车辆与前车距离是否过近,若是,则发送降速指令至车速控制装置;判断降速过程中与后车距离是否过近、或将车速降低至设定值的过程中与前车距离是否仍然过近,当至少其中之一满足时,发出提醒信号,提醒驾驶员停止减速、进行变道处理;车速控制装置,其用于接收降速指令,进行降速操作。本发明综合考虑自身车辆与前车的安全距离、道路环境、与后车的安全距离,当检测到与前车距离过近时,首先进行降速处理,当速度降低到设定值后仍然与前车距离过近、或在降速过程中检测到与后车距离过近的情况时,此时提醒驾驶员停止减速、进行变道处理。
