Description
(1) technical field:
The utility model relates to automobile fixed speed cruise system field.
(2) background technology:
Along with the raising of developing of automobile industry and living standards of the people, automobile pollution constantly increases, and the personnel of corresponding acquisition vehicle drive qualification also constantly increase, yet the great traffic injuries and deaths accident that is caused also increases thereupon.
Although auto-safety mechanism constantly occurs and be constantly perfect in the market, degree of automation improves constantly, as safety strap, safety air bag, ABS antiblock device and constant speed cruising system and intelligent vehicle collision avoidance system.But for a long time, can not stop traffic accident fully.Wherein, since automobile driver can not timely and effective emergency braking in addition the mistake traffic accident of trampling throttle and being caused occupy very high percentage.
Study carefully its cause, still because existing gas control system exists certain contradiction defective to cause with the brake control system.The common three pedal control systems that adopt of domestic and international various automobiles are the '20s American Henry Ford nineteen twenty-eight inventions in last century at present, be pedal of clutch, brake pedal and Das Gaspedal, for these years, remove and removed pedal of clutch from after automatic transmission with hydraulic torque converter occurs, other is not retrofit always.This two control system can not allow chaufeur in driving the way " grasp bearing circle with breathless interest, trample brake pedal wholeheartedly ".The chaufeur right crus of diaphragm must be trampled Das Gaspedal control throttle size all the time when automobile normal running, needs conversion between Das Gaspedal and brake pedal continually simultaneously.When running into emergency situation and need immediately drag, because chaufeur must allow right crus of diaphragm leave Das Gaspedal in advance, and then trample brake pedal brake snub vehicle, the course of reaction and the sole shift action process of the obvious like this human thinking that just has a people, analysis, judgement, since so serial process to little waste 0.5 second time, stopped over the first the most valuable braking time, and can not timely and effective emergency braking automobile, often just be easy to lead to the Traffic Collision accident.Travel for 60 kilometers/hour as automobile speed, 0.5 second time just can be run out of 8.33 meters, was equivalent to prolong the automobile brake distance, thereby had increased danger coefficient.Relatively poor for psychological quality in addition and begin to learn chaufeur, because Das Gaspedal is identical with the trample action of brake pedal, then step on sky often, or mistake is trampled Das Gaspedal suddenly as brake pedal in flurried, the result is just the contrary, make original avoidable Traffic Collision accident take place, slight has become seriously.
Automobile fixed speed cruise system (CRUISE CONTROL SYSTEM is abbreviated as CCS, is called the cruise mobile devices again, automatic speed control system, personal vehicle system etc.).SET/-(setting/deceleration key), the RES/+ (recovery/accelerator key) of at present existing automobile fixed speed cruise system control switch all adopt mechanical switch button or thin-film switch button, and what provide is the switch conduction signal.Existing automobile fixed speed cruise system basic functions and operating mode: will open the initialization of constant speed cruising system main switch main switch start-up system and await orders, and trample the required speed of a motor vehicle of Das Gaspedal adjusting control with right crus of diaphragm;
(1) speed of a motor vehicle is set: after the speed of a motor vehicle is stable, by hitting SET/--(setting/deceleration key), just can stores the moving velocity of this time and set the speed of a motor vehicle, and can keep this speed to travel;
(2) eliminate function: when stepping on clutch pedal, brake pedal or place " P ", " R ", " N ", " 1 " position to remove the cruise function immediately gear level by hitting CAN (releasing key), still, the speed of above-mentioned regulation and control continues storage;
(3) restore funcitons: after cruise is removed, possess automatic memory function, recover the former setting speed of a motor vehicle by hitting RES/+ (recovery/accelerator key);
(4) speed fine setting acceleration, deceleration; Under the state of constant speed,, quicken 2 kilometers by hitting RES/+ (recovery/accelerator key) at every turn.By hitting SET/--(setting/deceleration key), slow down 2 kilometers at every turn;
(5) speed is quickened continuously, is slowed down; Under the state of constant speed, by hitting RES/+ (recovery/accelerator key), quicken continuously continuously, get back to original speed of a motor vehicle constant-speed traveling (using when overtaking other vehicles) after loosing one's grip.By hitting SET/-(setting/deceleration key), to slow down continuously, the back of loosing one's grip is with speed of a motor vehicle constant-speed traveling at that time.
Though existing constant speed cruising system can free right crus of diaphragm from Das Gaspedal, be placed on the brake pedal, can overcome above-mentioned defective, guarantee that right crus of diaphragm can be at effective braking vehicle of the very first time.But, also there is following defective this system in itself: because the speed of a motor vehicle adjusting function of this system control switch device under the cruise state can only be finely tuned the speed of a motor vehicle, after causing this default speed of a motor vehicle, promptly under the state of cruise, the work efficiency of the master cock regulation and control speed of a motor vehicle is too low, even producer simply changes the work efficiency that software improves the master cock regulation and control speed of a motor vehicle, still can not regulate and control the speed of a motor vehicle flexibly, promptly lose speed is finely tuned the acceleration, deceleration function again; So producer is for the sake of security, can only take the design concept guarded, the system that sets when being lower than 60 kilometers of speed per hours automatically terminates the function restriction and uses; And road conditions had harsh restriction, must on express highway or totally-enclosed road, use; Road conditions complexity on non-sealing road, for example on national highway, the influence of some cyclecar under powers, avenue pedestrian's street crossing and traffic lights crossing cause obstacle can for the automobile that cruises.Even this system function restriction of automatically terminating of not having 60 kilometers of speed per hours is at this moment used, can not resemble the flexible control speed of a motor vehicle the Das Gaspedal, cruise do not have yet practical significance on the contrary because remove, setting operation switch motion complexity becomes trouble more.In addition because master cock RES/+ (recoverys/accelerator key) design exists safe potential safety hazard etc. when the use restore funcitons, if compare with traffic at that time, the speed of a motor vehicle of setting of cruising is too high, even chaufeur forgotten the speed of a motor vehicle of original setting, then with dangerous.Although also have automobile intelligent collision avoidance system and constant speed cruising system are combined, can automatic deceleration when running into obstacle or take brake measure, but, because this technical sophistication, poor stability, with high costs, and from the navigating mate psychological application, belong to passive measure and can not allow navigating mate trust.So existing in sum constant speed cruising system Occupation coefficient is not high, can not timely and effective emergency braking in addition the mistake security hidden trouble of trampling Das Gaspedal still follow always and perplex us.
