Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, the gear determination device for the intelligent driving test system provided by the invention comprises a microprocessor, and an angular acceleration sensor 3 and a linear acceleration sensor 4 which are arranged on a shift lever 1, wherein the angular acceleration sensor 3 and the linear acceleration sensor 4 swing together with the shift lever 1, so that a series of angular acceleration information and linear acceleration information of the shift lever 1 in a shifting action can be obtained, and thus the motion track information of the shift lever 1 is obtained; the microprocessor stores a plurality of shift track threshold data, each shift track threshold data corresponds to a shift operation, and is obtained by combining standard track data of the shift operation with a set allowable deviation degree, for example, deviation values are respectively arranged on two sides of the standard shift track data, and the shift lever 1 track threshold data is the superposition of the standard shift track data and the deviation values on the two sides. When the motion trail information meets any one of the shifting trail threshold data, the gear of the shifting rod 1 is judged to be the gear corresponding to the shifting trail threshold data, and finally the microprocessor outputs the judgment result to the driving test system.
As can be seen from the above, in the gear determination device according to the embodiment of the present invention, the actual shift trajectory information of the shift lever 1 is monitored by the angular acceleration sensor 3 and the linear acceleration sensor 4 which are arranged on the shift lever 1, and the shift trajectory information is compared with a plurality of shift trajectory threshold values by the microprocessor, so as to determine the shift process, thereby eliminating the technical problem that the final position of the shift lever 1 is determined only by the gear sensor in the conventional gear determination, so that the gear shift misdetermination is caused by a large gear gap of the driving test vehicle.
In some embodiments, the plurality of shift trace threshold data may be manually written into the microprocessor, and for a certain fixed vehicle type, the shift motion and the standard motion trace of the shift lever 1 are substantially consistent, so that a deviation value may be manually set on the basis of the standard motion and the motion trace, so as to uniformly write various shift trace threshold data into each vehicle in advance before the driving test vehicle is put into use, so that the auxiliary determination of the gear may be directly performed after the driving test vehicle is put into use.
In some embodiments, the shift trajectory threshold data is acquired by the microprocessor through the angular acceleration sensor 3 and the linear acceleration sensor 4, and since the gear panel is not worn before the new driving test vehicle is put into use, the gear clearance and the motion trajectory of the shift lever 1 at this time are still relatively standard, so that the motion trajectory information of each shifting process of the shift lever 1 at this time can be acquired by the microprocessor, and on the basis of the motion trajectory information, preset running deviation degree information is automatically added, and finally the shift trajectory threshold data is set and formed. The method has the advantages that gear shifting track threshold data do not need to be calculated in advance for each vehicle type, and design cost is saved. In addition, even if the same type of vehicle exists, the actual gear shifting tracks of all vehicles are different, so that gear shifting track threshold value data are formulated according to the actual motion tracks of the vehicles at the beginning of use, and the formulated gear shifting track threshold value data can be more accurate.
The angular acceleration sensor is preferably a gyroscope, and the gyroscope can acquire not only angular acceleration information of the shift lever 1, but also speed information of the shift lever 1 in horizontal, vertical and pitching directions, so that the real-time posture of the shift lever 1 can be accurately acquired, and the movement track of the shift lever 1 can be more accurately recorded.
In some embodiments, the gear determination device may further include a limiting frame 2 sleeved outside the gear shift lever 1 and connected to the vehicle body, and a shape of an inner frame of the limiting frame 2 is adapted to a shape of an inner frame of the gear shift panel to limit a movement track of the gear shift lever 1. For a driving test vehicle with a gear panel which is worn out greatly, after the gear judging device is added, gear shifting track threshold data cannot be formulated through the angular acceleration sensor 3 and the linear acceleration sensor 4 which are arranged on the gear shifting rod 1. After the limiting frame 2 is additionally arranged, on one hand, the movement track of the gear shifting rod 1 is limited from the mechanical structure, so that the movement track of the gear shifting rod 1 is more standard, and therefore, the judgment of the gear sensor on the gear is facilitated, and the correct judgment of a driving test person on the gear is also facilitated.
On the other hand, after the limit frame 2 is additionally installed, since the shift trajectory of the shift lever 1 becomes standard, the shift trajectory threshold data can be acquired and calculated by the angular acceleration sensor 3 and the linear acceleration sensor 4 which are arranged on the shift lever 1, so that the gear determination device can be implemented on a driving test vehicle which is worn.
Furthermore, the connection can be dismantled with the automobile body to above-mentioned spacing frame 2 preferred, because spacing frame 2 also can take place wearing and tearing after using a period, when the great back of spacing frame 2 degree of wear, the fender position panel of changing the vehicle is compared with the movement track of standardizing gear level 1 to removable new spacing frame 2, and it is more convenient, the cost is lower to change spacing frame 2.
In some embodiments, the gear determination device further comprises a magnet 5 arranged on the shift lever 1, and further comprises a plurality of magnetic induction sensors 6 arranged on the vehicle body and located on the lateral side of the magnet 5 and distributed at intervals, wherein the plurality of magnetic induction sensors 6 are respectively connected with a driving test system, specifically, a hall sensor can be adopted, and the driving test system obtains the gear information of the shift lever 1 through the distance induction between the plurality of magnetic induction sensors 6 and the magnet 5.
Specifically, taking the configuration shown in fig. 2 as an example, three magnetic induction sensors 6 are provided on the left side or the right side of the shift lever 1, the middle one of the magnetic induction sensors 6 corresponds to the neutral position of the manual gear, the front one of the magnetic induction sensors 6 corresponds to the left-right positions of the reverse gear, the first gear, the third gear, and the fifth gear of the manual gear, and the rear one of the magnetic induction sensors 6 corresponds to the left-right positions of the second gear and the fourth gear of the manual gear; because the gear level 1 is respectively when reversing gear, first gear, third gear and five keep off (or two keep off, fourth gear) positions, magnet 5 on the gear level 1 is different with corresponding magnetic induction sensor 6's distance, consequently the fender position that gear level 1 place is judged to the distance information that three magnetic induction sensor 6 sensed.
It should be understood that the plurality of magnetic induction sensors 6 are not limited to be disposed on the left or right side of the shift lever 1, but may be disposed on the front or rear side of the shift lever 1, and the principle is the same as the above-mentioned arrangement, and thus, the description thereof is omitted.
Furthermore, this keep off position decision device preferably still includes non-magnetic metal cavity 7, and a plurality of magnetic induction sensor 6 set up in non-magnetic metal cavity 7, and non-magnetic metal cavity 7 can shield the interference of other electromagnetic signal on the automobile body, also can prevent that personnel in the car from touching magnetic induction sensor 6.
The invention further provides a driving test vehicle which comprises the gear determination device for the intelligent driving test system, and the driving test vehicle can more accurately acquire gear engagement information of driving test personnel through the gear determination device and give accurate determination, so that the intelligent application of the driving test system is improved, and the accuracy and the use experience of the intelligent driving test vehicle are improved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
