Background technology
Current self-adaption cruise system is the transport condition by monitoring front car amount mounted in the radar of Chinese herbaceous peony, our vehicle according to the transport condition of front vehicles automatically make accelerations, deceleration, at the uniform velocity, the transport condition braked.Because this kind of self-adaption cruise system detects the running status of front car amount simply by a radar, without the environmental factor in view of driving and the influence that is brought of surrounding vehicle.Therefore, the cruise that current self-adaption cruise system is intelligently used for simple road conditions drives.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided a kind of automobile intelligent cruise control system and its control method.The automobile intelligent cruise control system can be optimized the cruising condition of automobile according to environmental factor and the operation conditions of surrounding vehicle.
The technical solution adopted by the present invention is as follows：
The invention discloses a kind of automobile intelligent cruise control system, including cruise control switch, velocity sensor, Foregut fermenters radar, main controller, throttle actuation module, main controller is connected with signal processing module, cruise control switch, velocity sensor, Foregut fermenters radar, left side detection radar, right side detection radar and rear car detection radar, weather detection module and tire pressure detection sensor are connected with signal processing module；Display screen, throttle actuation module, cruise indicator lamp drive module and voice driven module are all connected on main controller；Main controller is connected with image processing module, and the first camera and second camera are connected on image processing module；
The cruise control switch, is mainly used in starting and stopping cruising condition, and cruise switch is by cruise start button, cruise cancel button, speed confirming button, acceleration button, retard button and recovers what cruise button was constituted；The velocity sensor is used to detect our speed；Front truck checks that radar, rear car detection radar, left side detection radar and right side detection radar are respectively used to detect the running status of other vehicles of four direction all around, and the parameter for predominantly detecting has speed, distance, acceleration；The weather module mainly for detection of weather situation；The tyre pressure sensor is arranged on inside tires is used to detect the pressure condition of tire；The signal processing module is mainly used in receiving and processing the information of cruise control switch, velocity sensor, Foregut fermenters radar, left side detection radar, right side detection radar, rear car detection radar, weather detection module and tire pressure detection sensor, and main controller is sent to after treatment；Synchronous signal processing module also receives and processes brake pedal signal, clutch engagement signal and fault-signal；The throttle actuation module receives the control signal of main controller, the aperture for adjusting air throttle；The cruise indicator lamp drive module receives the control signal of main controller, the on and off for controlling cruise indicator lamp；The control signal that the voice driven module receives main controller is used to control loudspeaker work, the display screen for showing various fault messages and warning message.
Further, first camera and second camera are separately mounted to the right and left on front window top, and with respect to the horizontal plane downward-sloping 3 ~ 5 degree, detect whether road surface ahead has barrier or depression using binocular imaging principle, the information that two cameras will be detected is sent to image processing module, and image processing module is sent to master controller after treatment.
Further, the control method of described control system is as follows：
1）Cruise state is started by cruise control switch, cruising speed is set, cruising speed is 30 ~ 120km/h, and the information that the running status of all detections of radar surrounding vehicles on car will be detected is sent to main controller；
2）If to no in front of our vehicle traveling lane, main controller controls us vehicle at the uniform velocity to be travelled according to the speed of setting to Foregut fermenters detections of radar；If Foregut fermenters detections of radar has vehicle to our vehicle traveling lane front, and the travel speed of the vehicle is less than the travel speed of our vehicle, then main controller controls our vehicle deceleration, it is ensured that safe stopping distance is reached between the vehicle, then uses and follows mode to travel；If there is lane change, or our vehicle lane change in front vehicles so that our vehicle front does not have vehicle to travel, then main controller controls our vehicle to be accelerated at the uniform velocity to be travelled until after the speed for reaching setting；
