The invention relates to an automobile active rear-ending-preventing control system and a control method. The automobile active rear-ending-preventing control system comprises a rear-ending-preventing control unit, an engine management system, a radar system, a steering wheel rotation angle sensor, a wheel speed sensor, a yaw velocity sensor, a safety belt detection unit, a safety belt pretightening control unit and a supplementary restraint system control unit, and the rear-ending-preventing control unit is connected with the engine management system, the radar system, the steering wheel rotation angle sensor, the wheel speed sensor, the yaw velocity sensor, the safety belt detection unit, the safety belt pretightening control unit and the supplementary restraint system control unit. The rear-ending-preventing control unit acquires the speeds of a vehicle behind and a vehicle ahead and the distances between the vehicles and a vehicle provided with the control system by means of the radar system, carries out analysis and calculation according to the speed of the vehicle, and sends a corresponding instruction to a related executing mechanism to control the acceleration of the vehicle, so that the vehicle can be prevented from being rear-ended by the vehicle behind. When rear-ending is unavoidable, an execution scheme which can ensure that the damage caused by collision is minor is chosen, the related safe executing mechanism is started in advance, and thereby the damage caused by rear-ending can be reduced to the max.
Description
technical field [0001] The invention relates to the technical field of automobile safety driving, in particular to an automobile active anti-rear-end collision control system and control method capable of avoiding the automobile being rear-end collision as much as possible and minimizing the possible damage caused by the rear-end collision. Background technique [0002] With the continuous development and progress of high-tech technologies such as network technology, radar detection technology, communication technology, and electronic control technology, the level of automotive electronics intelligence has developed rapidly in recent years, especially in terms of automotive active safety. The introduction of advanced technologies, such as: lane departure warning technology, lane keeping technology, driver fatigue detection system, collision prevention system, run-flat tire control system and so on. However, the current application of these active safety technologies mainly c...
