Below in conjunction with accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.The assembly of the embodiment of the present invention describing and illustrate in usual accompanying drawing herein can be arranged with various different configuration and design.Therefore, below to the detailed description of the embodiments of the invention provided in the accompanying drawings and the claimed scope of the present invention of not intended to be limiting, but selected embodiment of the present invention is only represented.Based on embodiments of the invention, the every other embodiment that those skilled in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Embodiment 1
After deliberation, when vehicle operating, the carelessness of chaufeur and the mistake of vehicular safety distance is estimated it is the key factor causing train operation accident to occur, contriver finds after deliberation, even if chaufeur learns this safety distance, a lot of chaufeur is for pursuing road speed, can take chances, take measures not in time, when it is really taken measures, accident often cannot have been stoped to occur, based on this, as shown in Figure 1, the embodiment of the invention discloses and a kind of automatically control vehicle (operating system) according to safety distance and perform brake instruction, avoid the safe travelling method that vehicle and surrounding objects bump against.
This safe travelling method is applied to vehicle control system, and described vehicle control system comprises harvester and control setup, and be previously provided with the positive braking distance of vehicle in described control setup, described method comprises:
Step S100: control setup obtains the running information of the vehicle current time that harvester collects in real time;
Wherein, running information comprises the road speed of vehicle current time and the distance with vehicle body surrounding objects; Road speed obtains by speed sensor, also the speed in vehicle can directly be obtained, the distance of vehicle and vehicle body surrounding objects obtains by distance measuring equipment (DME), such as: gather vehicle body ambient signals according to ultrasonic equipment, laser radar range equipment, infrared distance measuring equipment etc.
Step S101: according to road speed and the positive braking distance of the vehicle current time obtained, calculate the safety distance threshold value of vehicle current time;
Wherein, positive braking distance is safety traffic braking distance standard value during vehicle release, the vehicle of different automobile types is different in the positive braking distance of same speed, same vehicle is also different in the positive braking distance of friction speed, but their basic brake principle is similar, such as: the positive braking distance of certain car is for maintaining safe distance as the millesimal of the speed of a motor vehicle, if the speed of a motor vehicle is 50km/h, positive braking distance is the 5m that maintains safe distance, and the speed of a motor vehicle is 120km/h, and positive braking distance is the 12m that maintains safe distance.
The account form of safety distance threshold value has multiple, such as: the positive braking safety distance of vehicle and objects in front draws by following formula: s2=s+ (v-s)+(v1-s)+(v2-s), wherein, s2 is the positive braking distance that present speed needs, s is that new car dispatches from the factory the positive braking distance of present speed standard road conditions, v is the positive braking distance of the different load-carrying of same speed road conditions, v1 is the positive braking distance of a certain gradient, v2 is the positive braking distance of vehicle after certain one-phase vehicle abrasion, because of road and vehicle condition reason, s2 is not necessarily very accurate, can s value be tuned up a bit, with guarantee driving safety, but the alerting ability driven can be affected because of the increase of s value.If install friction plate telescoping mechanism on chassis, the positive braking distance of s2 can be shortened, the alerting ability of energy guarantee driving safety and driving like this; Again such as: control setup can record the brake data of vehicle and add up, obtain the brake data (obtaining by data sharing) of all the other vehicles identical with this vehicle vehicle, by the brake data analysis before this vehicle under current line vehicle speed, obtain the safety distance threshold value under current line vehicle speed; Again such as: corresponding threshold value, by large data analysis, by input control device direct when dispatching from the factory, or is inputted by user voluntarily.
Step S102: judge whether the distance of described vehicle current time and vehicle body surrounding objects reaches the described safety distance threshold value of current time;
Step S103: be, controls described vehicle and performs brake operation;
Step S104: otherwise be failure to actuate.
When vehicle judges to show that the distance of vehicle current time and vehicle body surrounding objects reaches safety distance threshold value, control setup directly controls vehicle and performs brake instruction, control vehicle to brake, vehicle and surrounding objects is avoided to bump against, without the need to driver's operation, promptness and the accuracy of emergency handling can be improved, decrease manually-operated uncontrollability, can traffic safety be significantly improved.
Controlling the condition that vehicle carries out brake operation has multiple, can in the following ways according to different situations:
Obtain vehicle and the distance of vehicle front object and the distance of vehicle and vehicle body rear object; Judge whether the distance of vehicle current time and vehicle front object reaches described first safety distance threshold value, and whether reach described second safety distance threshold value with the distance of vehicle body rear object; If the distance of the first safety distance threshold value or vehicle and vehicle body rear object that the distance of vehicle current time and vehicle front object reaches current time reaches the second safety distance threshold value of current time, then the brake gear controlling vehicle performs brake operation.
If execution brake, then explain the situation very critical, in order to ensure the promptness of brake, the electric oil pump that control setup can control vehicle is opened, and controls electric oil pump toward injection brake solution in brake house steward, to complete emergency brake rapidly, avoids accident to occur.
It should be noted that, when reality uses, preferred setting is greater than the alarm threshold value of (emergency brake) safety distance threshold value, when the distance of vehicle and object to be in alarm threshold value but to be less than safety distance threshold value, warning device is reported to the police, chaufeur is reminded to perform the operation such as braking, deceleration, if chaufeur carelessness error, do not perform brake operating, distance is caused to reach (emergency brake) safety distance threshold value, then move device by control setup nonstick system of control and complete emergency brake, the mode of this dual threshold, double insurance, fully can guarantee the safety of driving.
In like manner, alarm threshold value is equally applicable to reverse travel operation, during vehicle forward, rear has object to knock into the back when reaching certain value to be accelerated or lane change by warning reminding chaufeur, emergency handling, if chaufeur is neglected, do not carry out corresponding operating, then automatically performed by control setup, vehicle and rear object are remained on safety distance, to guarantee the safety of vehicle operating.
Wherein, the distance of vehicle front, rear and object is by arranging distance measurement equipment obtain at vehicle front, rear respectively; The method of calculating of the safety distance threshold value of vehicle and front vehicle (object) has multiple, with the safety distance of vehicle front object method of calculating similar, do not do repeat specification at this; When the distance of vehicle current time and vehicle front, rear object all exceedes safety distance threshold value, by driver's operation, more can improve the alerting ability of operation, make chaufeur according to the present situation, empirically sweetly disposition, break away from " predicament ".The safety that different operating effectively can guarantee traveling is performed in a manner described according to different situations.
According to the method described above, control setup can obtain vehicle current time (emergency brake) safety distance threshold value according to running information, automatic sending controling instruction, automatically brake when the distance of vehicle and surrounding objects reaches safety distance threshold value, vehicle and surrounding objects is avoided to bump against, setting like this, substantially increase the accuracy of security management and control during driving and intelligent, reduce manually-operated error, traffic safety accident is strangled before generation, effectively can improve the safety of driving.
In order to " truly " distance making chaufeur can obtain vehicle and surrounding objects in real time, avoid occurring because driving the accident caused with " sensation ", in the embodiment of the present invention, the read out instrument that the safety distance threshold value of the vehicle current time calculated is sent in control system in real time also shows by control setup.According to actual conditions, also can warning device be set, when the distance of vehicle and surrounding objects exceedes safety distance threshold value, controls this warning device and report to the police.
When driving, vehicle and to keep a safe distance between front and rear object be the key factor guaranteeing traffic safety, contriver studies discovery, it is also the another key factor guaranteeing traffic safety that vehicle and both sides object keep a safe distance, and provides wherein a kind of distance controlling vehicle and both sides object and remain on the implementation of safety distance threshold value in the embodiment of the present invention:
Running information also comprises the direction of traffic of described vehicle, is previously provided with effective locking distance threshold of described vehicle and vehicle body both sides object in control setup; According to road speed and the direction of traffic of the vehicle current time obtained, and active distance threshold value, calculate the locking distance threshold of vehicle current time; Judge whether the distance of vehicle current time and vehicle body both sides object reaches locking distance threshold, is, the directional lock locking apparatus controlling vehicle carries out locking to the direction reaching locking distance threshold; Obtain road speed and the direction of traffic in another moment of vehicle, and active distance threshold value, judge whether the distance of another moment of vehicle and vehicle body both sides object reaches locking distance threshold, is keep lockup state, otherwise the directional lock locking apparatus controlling vehicle removes locking.
The locking distance threshold of vehicle current time is obtained according to running information, control setup can automatic sending controling instruction, when the distance of vehicle and either side object reaches locking distance threshold, can to this side to carrying out locking, make chaufeur cannot again to this side direction of operating dish, namely vehicle is made to offset to this side again, effectively ensure that vehicle and both sides object all keep a safe distance, substantially reduce scratch, the accident odds such as shock, the locking distance threshold in vehicle each moment is calculated, after locking action executing, if locking condition ceases, locking can be removed in time, ensure that safety and the alerting ability of driver's operation.
Separately, in order to ensure the accuracy of safety distance threshold value setting, in time setting safety distance, preferably by vehicle load, the information such as road conditions are taken into account, adjust safety distance threshold value and locking distance threshold according to different load-carrying, the gradient, such as: under same speed, load-carrying, distance threshold during descending must be greater than distance threshold during upward slope; Under same speed, different load-carrying, load-carrying is heavier, and distance threshold is larger.
Wherein, vehicle load is by acquisitions such as pressure sensor, electrometer treasures, and the gradient obtains by Slope Transducer.
In said system, distance measuring equipment (DME) can be measured the distance of the headstock of vehicle and objects in front, speed measuring device can be measured the road speed of vehicle, control setup obtains the detection data of speed measuring device, Weight detecting device, slope detection device, and COMPREHENSIVE CALCULATING goes out current (promptly) safety distance threshold value.When implementing, by the Based Intelligent Control to control setup, the safety of driving can be significantly improved, such as: above arrangement vehicle only otherwise the situation of road occupying, just can be avoided getting into an accident, if set sensoring in control setup, the safety distance threshold value of the other side's current vehicle speed can be received, if can pass through to driving the safety distance threshold value receiving the other side, the safety distance threshold value of adjustment (increase) current vehicle speed needs at one-way two.Even if to provisional capital, two chaufeurs do not see that the other side also can not get into an accident in one way only, two equal the safety distance threshold value sum of two cars to the active distance of emergency brake of driving.Control setup, according to the other side's safety distance threshold value obtained, adjusts the safety distance threshold value of oneself, if when reaching (promptly) safety distance threshold value, chaufeur does not control brake, and control setup can control brake equipment sudden stop rapidly.In order to improve traffic safety, when implementing, preferably alarm threshold value is set, before driving reaches safety distance threshold value, first will reach alarm threshold value, control setup can be braked by first alarm chaufeur, if the chaufeur side of execution starts brake equipment automatically, so, greatly can improve the accuracy of security management and control during driving and intelligent, reduce manually-operated error, traffic safety accident is strangled before generation, significantly improve the safety of driving.
