Abstract

PURPOSE:To secure a good running feeling by a method wherein a vehicle speed sensor and an acceleration sensor are connected to a jammed traffic decision means and the median value of an average vehicle speed as well as the acceleration of the vehicle in the advancing direction thereof are operated based on both of the signals in order to decide the jammed traffic. CONSTITUTION:The vehicle speed sensor 400 and the acceleration sensor 500 are connected to the jammed traffic decision means 206 and the median values of the average vehicle speed as well as the acceleration of the veicle in the advancing direction thereof are operated by sampling the vehicle speed signal of the vehicle speed sensor 400 as well as the acceleration signal of the acceleration sensor 500 for a preset period of time. The results of these operations are compared with data memorized previously to decide whether it is the jammed traffic or not. According to this method, the jammed traffic condition may be decided based on the average vehicle speed as well as the cumulative frequency of generation of the acceleration of the vehicle in the advancing direction thereof, therefore, the good running feeling may be secured by a method wherein a speed change diagram is switched to the same in accordance with the jammed traffic when surplus driving power is large enough.

Description

[Detailed description of the invention]

<Industrial Application Field> The present invention relates to a gear shift control (11) device of an automatic transmission, and more specifically, the present invention relates to a gear shift control (11 device) of an automatic transmission. (referred to as running condition)
In this case, the transmission diagram is different from the setting line state) 1!
1) Automatic gear shifting is performed by changing the speed according to the driving condition (11). <Prior art> In general, an automatic transmission has d3 and C1.The shift point is usually set to 4'T to drive fairly smoothly on public roads. ), for example, depending on the engine speed and the engine load condition. 1) It is set at a predetermined point. However, in the above-mentioned conventional system, the slow speed point is fixed at a predetermined point.
- When driving in a different driving condition than the set driving condition, for example, when driving on a steep slope, the required force changes and the shift point changes depending on the driving condition. Therefore, conventionally, Bjjl':356-
393 b As disclosed in Publication No. 3, when driving on a slope, the shift diagram should be changed according to the slope f of the slope. By the way, the required acceleration force (J,
Since it is sticky and small, the shift point does not correspond to the driving condition as in the case of driving on a slope, and the vehicle often runs in first gear, which has the disadvantage of reducing fuel efficiency. (Objective of the invention) Purpose of the present invention (jl, In addition to the speed change diagram corresponding to steady driving, a separate speed change diagram corresponding to heavy driving is provided (J. Shibu? (i) Switching to the one according to the driving condition (from 1), the shift point will correspond to the driving condition in both d3 during steady driving and when driving in traffic jams!
Ensures a good driving feel during steady driving.
Tsutsushibu? 11) J that aims to improve fuel efficiency while driving
: It's about being able to eat sea urchins. Furthermore, if it is possible to change the shift diagram according to such steady driving and Shibu 81) driving,
The cumulative occurrence frequency 11 of the acceleration in the traveling direction of the vehicle shown in FIG. 12! As can be seen from the J property, the solid line -(
・Accepted 1;; 3 runs ++11, vehicle's) 1 line)
While there is a wide range of changes in the acceleration rate (from L' stone value to 0.2'qJ: ri slightly human threshold),
The dashed line indicates that when driving in a traffic jam (this is within a narrow fΦ range of 1.0 and 10), Δ, S, and the traffic jam [(in a traffic jam, the average vehicle speed and the vehicle's forward direction acceleration! Judgment is made based on the cumulative occurrence frequency of 3 Rt. Running (“Keeping the j-feel tilted”

[,-There is. (Part 11 of the present invention) -1-2 To achieve the objective, 1'+1''+4 points of δ0 are
According to Figure 1, in Figure 1 a5, 'L-:/Jin 1' output shaft has 4;
The output shaft (41) of the converter 10 (1, to which the gearboxes 70 are connected, respectively,
^70 is 0q) where the power transmission path is switched by the speed change switching means 75 operated by the hydraulic actuator upstream 78.
The fluid actuator 78 is one in which the supply of fluid is controlled by an electromagnetic means 80. The rotation speed signals a5 and r of the rotation speed sensor 201, which detects the rotation speed of the output shaft of the torque converter 10, and the load signal of the engine load roner 202, which detects the large jaggedness of the load of the engine 1. The first shift 1 to change signal generated from the first shift 1 to change signal determination means 300 and the second shift signal generated from the 22nd shift 1 to change determination means 301 based on the
Is the traffic jam driving determination means 206 1fil? :"When it is not determined that there is ←2 is based on the 1st 1st shift 1-change signal'
Well, when it is determined that it is Shibu Wit again, the second shift 1 ~
The vehicle speed is controlled by a controller m 303 based on the change signal, and the traffic jam determination means 206 receives the vehicle speed signal @ibJ: from the vehicle speed sensor 400 that detects the vehicle speed. The acceleration signal of the acceleration sensor 500 that detects the acceleration Fα in the direction of travel is set for 1 hour → non-pulling, and the acceleration signal is determined based on the average vehicle speed and the median value of the acceleration in the direction of travel of the vehicle. ;1) I'll determine whether or not the vehicle is in a running state. As a result, during steady running, the first shift change determination hand 12300 automatically switches the gearbox IN 70 based on the first shift change determination hand 12300, and automatically shifts the gear according to the shift diagram C corresponding to steady running. (On the other hand, when driving in traffic jams, the second shift 1st shift indicator judgment means 30
11) Driving (Automatic shifting is performed according to the corresponding transmission diagram, so steady driving is achieved) The C shift point is adjusted to suit the driving conditions for both time and driving in traffic jams, and the average vehicle speed A3 and vehicle acceleration in the forward direction of the vehicle are both low <1. At the point in time, the congested driving state is determined by the congested driving determining means 206, and the driving force, which is proportional to the abrasion in the direction (11) of the old vehicle with a low average vehicle speed, becomes low (C) 31 ↓) 11) Switch to the shift diagram according to the driving J: I'm doing it. In addition, in the present invention, instead of the acceleration signal of the acceleration sensor,
car) * By detecting the change in Renri's vehicle speed signal 5.1-, even if the acceleration signal is set to 11V, the car's speed will increase.
, Of course there is C. In addition, to determine whether or not the above-mentioned WTL running state exists, instead of comparing the median values, it is possible to compare the vehicle's progress (the average value or the maximum value of the forward acceleration). Since the above-mentioned average value or maximum value may vary greatly depending on the operating condition of the heavy vehicle, it is desirable to use the median value, which has a small fluctuation range, for statistical processing. (Effects of the Invention) Therefore, according to the present invention, the shift diagram, which serves as a reference for automatic shifting of the gear shift mechanism, is determined based on the determination result of the traffic congestion driving determination means. 1 sea change signal and 2nd shift to 1 change determination means.
2F1~Change (E!J3) is selected as appropriate, so it is possible to use J3 both during steady driving and when driving in traffic jams, and to change the shift point to an appropriate one according to the driving condition. 11) Since the driving judgment means is configured to judge the traffic jam driving condition based on the average 1st speed and the median value of the vehicle's acceleration in the direction of travel, when the required driving force is small, In other words, when the surplus driving force is large, the transmission diagram can be switched to the direction of reducing the surplus driving force, which corresponds to driving in traffic jams, resulting in smooth driving (111 driving while maintaining the driving force). The purpose is to improve the fuel efficiency of the invention. (Example) Example K as a specific example of the technical means of the present invention
