Detailed description of the invention
For convenience of to understanding of the present utility model, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of accessory system structured flowchart during for automobile up slope, this system comprises information acquisition system, letterBreath treatment system, control system and initialization button;
Information acquisition system comprises trailer-mounted radar device (3), vehicle speed sensor and vertical gyroscope sensor; Information gatheringSystem is for being obtained from the range information of car and front barrier, from car speed information and from car vehicle body angle of pitch information, andSend the information collecting to information processing system;
The information that information processing system is obtained information acquisition system is processed, obtain front barrier relative distance, fromThe car speed of a motor vehicle and from the car vehicle body angle of pitch;
Whether the data that control system obtains information processing system are further processed, analyze from the distance of car and barrier and locateIn safe condition, if dangerous, start electric brake brakes, the air throttle of close the throttle control system simultaneously,Make air throttle lose acceleration capacity, alarming device is opened;
Display unit shows the intervention operation of electric brake brakes and air throttle control system;
Initializing button is the order of assigning for stopping this system operation process deactivation system, when electric brake starts, and jointWhen valve loses acceleration capacity, automobile stops, and now presses initialization button, electric brake brake off, and air throttle recoversAcceleration capacity, accessory system returns to original state; In the time not needing accessory system, the long 5s shutdown system of pressing, system can beAutomatically open when automobile starting next time.
As shown in Figure 2, three trailer-mounted radars lay respectively at left side 1, centre 2, the right side 3 of chassis front end, are used for visitingWhether Suo Qianfang has barrier and the range information with barrier, and sends the information collecting to information processing system.Fig. 3 is the example sketch of the utility model in upward slope process, and first vertical gyroscope sensor is collected once every 0.05sFrom car vehicle body angle of pitch information, and three angle of pitch information in adjacent 0.15s are compared, if at adjacent 0.15sThe angle of pitch information of interior collection is all greater than 6 °, and system just judges that automobile is in upward slope process. And in upward slope process, ifThe luffing angle of collecting in 0.15s is between 6 °～10 °, and system judges that automobile is in slight gradient upward slope process; ThisIn time, records from the car speed of a motor vehicle by vehicle speed sensor, if the speed of a motor vehicle is greater than 50km/h, starts electric brake and slows down, if carSpeed is less than 50km/h, and automobile moves ahead as usual; Owing to not setting safe distance, system is judged safety, and automobile balance crosses upward slopeRoad. If the luffing angle of collecting in 0.15s is between 10 °～20 °, system judges that automobile is in moderate gradient upward slope processIn; Now record from the car speed of a motor vehicle by vehicle speed sensor, if the speed of a motor vehicle is greater than 30km/h, starts electric brake and slow down,If the speed of a motor vehicle is less than 30km/h, automobile moves ahead as usual; If trailer-mounted radar detects from car and front obstacle distance little simultaneouslyIn 10m, start electric brake brakes and make air throttle lose acceleration capacity, thereby making car deceleration until stop; WhenPress while initializing button, electric brake brake off, air throttle recovers acceleration capacity, and automobile balance crosses upward trend. IfThe luffing angle of collecting in 0.15s is between 20 °～30 °, and system judges that automobile is in heavy grade upward slope process; NowRecord from the car speed of a motor vehicle by vehicle speed sensor, if the speed of a motor vehicle is greater than 10km/h, starts electric brake and slow down, if the speed of a motor vehicleBe less than 10km/h, automobile moves ahead as usual; If simultaneously radar detection is in the time that car and front obstacle distance are less than 2.5m,Start electric brake brakes and make air throttle lose acceleration capacity, thereby making car deceleration until stop; Initial when pressingWhile changing button, electric brake brake off, air throttle recovers acceleration capacity, and automobile balance crosses upward trend. If at 0.15sThe luffing angle of interior collection is greater than 30 °, and system judges that automobile is in dangerous gradient upward slope process, and warning lamp is bright and startup oftenElectric brake brakes is braked.
