Generally, the speed change characteristics of a continuously variable transmission are uniquely determined by being controlled mechanically by the profile of a shift cam or electronically using a preset table. and,
For example, in the low range of throttle [7flU], the upper limit of engine speed is suppressed to encourage gear shifting, and the specification prioritizes fuel efficiency.
In the region of high throttle opening, conversely, it is considered to encourage the upper limit of engine rotation to give priority to output. By the way, even if an ideal shift pattern is determined for the continuously variable transmission J3, it does not necessarily match the user's driving preference. Once the shift pattern has been set, there is no room to change it depending on the user's driving.For this reason, it is desired to make the shift pattern variable. Regarding making the 5th speed pattern variable in a continuously variable transmission, for example, Japanese Patent Application Laid-Open No. 60-14648
There is a prior art in Japanese Patent Publication No. 2003-11002, which shows that a shift pattern is selected in relation to the small amount of cargo loaded on a vehicle. [Problems to be Solved by the Invention] By the way, in the method of the above-mentioned prior art, the shift range is shifted to -711 to the low gear side or the high gear side in relation to the small loading amount of the vehicle. become. In this regard, the user's driving habit is that the speed change range is uniformly changed! It is not possible to adapt to this. The present invention has been made in view of these points, and it is an object of the present invention to provide a control method for a continuously variable transmission that allows a shift pattern to be adapted to the knee+7 driving preference. [Means for solving the problem 1] In order to achieve the second objective, the present invention removably attaches an EPROM that stores data of a gear shift pattern to a control unit that controls the gear shift of a continuously variable transmission. However, the EPROM stores data on a speed change pattern specific to each user's driving condition, and the speed change is controlled based on the data in the EPROM. [Function 1] Based on the above method, it becomes possible to control the speed change of the continuously variable transmission in accordance with the preferences of each driver, thereby promoting improved driverability. [Example 1] Hereinafter, an example of the present invention will be described based on the drawings. In FIG. 1, an outline of a transmission system including a continuously variable transmission to which the present invention is applied will be explained.
Connect to. The continuously variable transmission 4 has a subshaft 6 arranged parallel to the main shaft 5, a primary pulley 7 on the main shaft 5, and a subshaft 6 on the main shaft 5.
The secondary pulley 8 is set numbered, and each pulley 7.8
is equipped with hydraulic cylinders 9 and 10 on the movable side, and a drive belt 11 is wound around it. Here, the primary cylinder 9 is set to have a larger pressure receiving area, and due to the primary pressure, the winding of the drive belt 11 around the pulleys 7.8 changes the ratio of diameters so that the speed is continuously variable. Further, the subshaft 6 is connected to the output shaft 13 via a one-phase transmission gear A712, and the output shaft 13 is connected to the final gear 1.
4. The transmission is configured to be transmitted to drive wheels 16 via a differential gear 15. Next, the hydraulic control system of the continuously variable transmission n4 will be described. It has an A-il pump 20 driven by the engine 1, and a line pressure oil passage 21 on the discharge side of the A-il pump 20 is connected to the secondary cylinder 10. Line pressure υ control valve 22. The oil passage 24 communicates with the gear shift control valve 23, and is connected to the gear shift control valve 23).
It communicates with the primary cylinder 9 via. The line pressure oil passage 21 further communicates with the regulator valve 25, and the constant regulator pressure oil passage 2G from the regulator valve 25 is connected to the solenoid valve 27, 28 and the speed change i, II IWJ valve 2.
Connects to one side of 3. Each of the solenoid valves 27 and 28 discharges pressure in response to a duty signal from the control unit 40 to generate control pressure. The control pressure from the solenoid differential 27 then acts on the line pressure control valve 22. On the other hand, the control pressure from the solenoid valve 28 acts on the other shift control valve 23. In the figure, reference numeral 29 is a drain oil passage, 31 is an oil pan, and 32 is a Δ refit. The line pressure control valve 22 controls the line pressure PL with respect to the gear ratio using the control pressure from the solenoid valve 27. The speed change control valve 23 has a regulator pressure and a solenoid valve 28.
Depending on the relationship between the control pressures from the line pressure oil passages 21 and 24, the oil supply position connects the line pressure oil passages 21 and 24, and the oil drain position where the line pressure oil passage 24 is drained. Then, the operating states of the two positions are changed according to the duty ratio to control the amount of oil supplied to or drained from the primary cylinder 9, and the speed change is controlled based on the relationship between the throttle opening degree and the engine rotation. To explain the electrical control system, engine rotation sensor 4
1. Medium speed sensor 42. It has a throttle angle sensor 43 whose respective sensor signals are input to the control unit 1 at 40. The control unit 40 is provided with a ROM 44 in which data of a hypothetical shift pattern is stored, for example, as a table of engine rotation and throttle opening. On the other hand, the speed change ratio is picked up from the table and a corresponding speed change signal is output to the solenoid valve 28. Also, Senna 41.42
A gear ratio is determined based on the engine rotation and medium speed, and a line pressure signal corresponding to this gear ratio is output to the solenoid valve 27. On the other hand, the control unit [-40 has the EP of user C9/Tl.
ROM45 is I III! ROM 44 or E by pressing the select button 46.
PROM45 can be selected. To explain how to input data to the EPROM 45, first, a user actually drives various types of vehicles in a manually-shifted pattern measuring vehicle, and the computer learns the driving patterns shown in FIG. 2 (2) or (2). Then, the user's habits are analyzed in relation to the throttle angle, engine rotation, and gear ratio, and data based on this is stored in the EPROM 45. With the above configuration, the control unit 40 stores two types of shift pattern data in the ROM 44 or the EPROM 45, and when the user selects the EPROM 45 with the select button 46, the continuously variable transmission 4 is activated based on this data. The speed change pattern is set according to the user's preference. Also, if you change the driver and select ROM44, based on this data, 1! ! ! The speed change t will be controlled imaginatively. It should be noted that it is possible to stock various types of shift pattern data in addition to the embodiments, and the control system is not limited to the above embodiments. [Effects of the Invention] As described above, according to the present invention, it is possible to set a shift pattern that suits the user's preference, and driving performance is improved. Since either one is selected, the contents of the shift pattern can be infinitely wide.
