The invention discloses an active safety vehicle forward early warning analysis system. An information acquisition module acquires vehicle driving data through a steering sensor, a speed sensor and a camera, calculates the speed, the acceleration and the driving direction of a vehicle, obtains a plurality of images of the camera in a period of time, analyzes the speed of the vehicle and the relative distance between the vehicle and a roadside obstacle, and analyzes whether the vehicle is collided at the existing speed or not according to the ratio of the speed to the distance, and an early warning module carries out voice indication of acceleration, deceleration and emergency braking on a driver, and carries out early warning in advance; when the driver does not operate according to instructions or an opposite vehicle runs too fast, a control module conducts forced mechanical braking, changes the running direction and speed of the vehicle, avoids accidents or reduces the damage degree as much as possible. Through the system, early warning can be conducted in advance in the running process, the driver is assisted in coping with crisis situations through mechanical braking, and the driving safety is improved.
本发明公开了一种主动安全车辆前向预警分析系统，所述信息采集模块通过转向传感器、速度传感器和相机对车辆行驶数据进行采集，计算出车辆的速度、加速度以及行驶方向，相机在一段时间内的多张图像，可以分析出来往车辆的速度和与路边障碍物的相对距离，根据速度和距离的比，可以分析出车辆保持现有的速度是否会发生撞击，所述预警模块对驾驶员进行加速、减速和紧急刹车的语音指示，提前进行预警，当驾驶员没有按指示操作或对方车辆行驶过快时时，所述控制模块进行强制机械制动，改变车辆的行驶方向和速度，避免事故发生或尽量减小损坏程度，通过上述系统，在行驶时可以提前进行预警，并通过机械制动辅助驾驶员应对危机情况，提高了驾车安全。
