Description

A kind of control switch device for vehicle constant speed cruise system

(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 utility models 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.).Present automobile fixed speed cruise system basic functions and operating mode:

(1) speed of a motor vehicle is set: after the speed of a motor vehicle is stable, by hitting 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 removing that key is stepped on clutch pedal, brake pedal or gear level placed " P ", " R ", " N ", " 1 " position can the temporary close system by hitting, remove cruise immediately, still, the above-mentioned speed that arranges continues storage;

(3) restore funcitons: after cruise is removed, possess automatic memory function, recover the former setting speed of a motor vehicle by hitting recovery/accelerator key;

(4) speed fine setting acceleration, deceleration; Under the state of constant speed,, quicken 2 kilometers by hitting recovery/accelerator key at every turn.By hitting 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 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 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 be as Das Gaspedal the flexible control speed of a motor vehicle, cruise do not have yet practical significance on the contrary because remove, setting operation switch motion complexity becomes and bothers more.In addition because master cock recoverys/accelerator key design exists safe potential safety hazard etc. when using restore funcitons, and as if comparing with traffic at that time, the speed of a motor vehicle of cruising of setting is too high, even chaufeur forgotten the speed of a motor vehicle of original setting, then with dangerous.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.

floor key groups

22231,22232,22233, key contacts on 22234 circuit card or the keyboard substrate 9 or plastic film switch 19 are closed simultaneously, depend on the size of thumb by the power of hitting, promptly the work efficiency that changes by the big more regulation and control speed of a motor vehicle of the power of hitting is fast more, otherwise it is slow more then to regulate and control the work efficiency that the speed of a motor vehicle changes.

Because setting/deceleration key 22 is arranged near on bearing circle wheel rim 35 positions, and is near from left hand thumb distance, makes things convenient for the quick flexible operating of left hand thumb; Recovery/accelerator key 23 is arranged on the bearing circle panel 34 near on bearing circle 1 home position, and is far away slightly from left hand thumb distance, the random maloperation recovery/accelerator key 23 of restriction left hand thumb; The layout that is provided with like this meets the human engineering principle, convenient, fast deceleration, and careful, restriction is quickened, and meets the vehicle security drive rule; Owing to can easily realize the control of handcar velocity modulation on bearing circle, chaufeur can free sole to place specially from Das Gaspedal and be in the drag armed state above the brake pedal; Meet one of vehicle security drive three elements, i.e. prevention in advance.

Operating mode: will open the 24 start-up system initialization of constant speed cruising system main switch main switch and await orders;

(1) speed of a motor vehicle is set: after the speed of a motor vehicle is stable, by hitting settings/deceleration key 22, just can stores the moving velocity of this time and set the speed of a motor vehicle, start the cruise function and also can keep at this moment speed to travel;

(2) eliminate function: when by hit remove that key 25 is stepped on clutch pedal, brake pedal or gear level placed " P ", " R ", " N ", " 1 " position touch interlock remove key 15 can the temporary close system, remove cruise immediately, but the above-mentioned speed that arranges continues storage;

(3) restore funcitons: after cruise is removed, possess automatic memory function, recover the former setting speed of a motor vehicle by hitting recovery/accelerator key 23;

(4) speed flexibility adjusting control; Under the state of constant speed, by hitting recovery/accelerator key 23, each unit time is quickened the N kilometer.By hitting SET/+ (setting/deceleration key) 22, each unit time deceleration N kilometer; Continuously by hitting recovery/accelerator key 23n unit time, quicken continuously that (kilometer of N * n) has promptly reset the speed of a motor vehicle constant-speed traveling of this moment after loosing one's grip; Continuously by hitting setting/22n unit time of deceleration key, slowing down continuously, (kilometer of N * n) has promptly reset the speed of a motor vehicle constant-speed traveling of this moment after loosing one's grip.The numerical value of N is along with changing by the size of hitting recovery/accelerator key 23 or setting/deceleration key 22 power, and is big more by the numerical value of the big more N of the power of hitting, otherwise then the numerical value of N is more little.Promptly big more by the long more speed of a motor vehicle variable quantity of regulating and control of the time of hitting, on the contrary the speed of a motor vehicle variable quantity of then being regulated and control is more little; The work efficiency of cart velocity modulation control is fast more more by the power of hitting, otherwise then the work efficiency of speed of a motor vehicle regulation and control is slow more.

When needing the emergency brake braking vehicle, sole can directly firmly be trampled downwards and be entered braking forced stroke braking vehicle fast by the drag armed state; The cruise function is directly removed, and it is minimum that throttle can moment be reduced to, (the fuel-based automobile is reached the engine idle state) thus effective braking vehicle.
