DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings. FIG. 1 constitutes a control device of the present invention,
A memory card 1 and a card reader 2 are shown. The memory card 1 is a well-known card-type key in which an IC memory unit 4 is built in a case 3 and a key 5 is detachably attached to a corner portion.

The IC memory unit 4 is provided with a power receiving coil 6, a transmitting / receiving section 7 and a known IC memory 8.
The memory 8 is composed of a CPU and various memories such as a ROM and a RAM.

The memory of the IC memory 8 stores skill level information, which will be described later, and, if necessary, other information such as an ID code.

The card reader 2 has a control unit 11 built in a case 10, a socket 12 to which a power source and various sensors, signal lines, etc. are connected, and a memory card 1 which is not shown in the figure but which is located above the control unit 11. It has a slot on the side for insertion by contact.

The control unit 11 is electromagnetically coupled to the power receiving coil 6 to generate electric power on the memory card 1 side, a transmitting / receiving unit 14 for communicating with the transmitting / receiving unit 7 of the memory card 1, a CPU 15, a RAM 16, and an EEPR.
With OM17.

The transmitter / receiver 14 receives the skill level information and ID code stored in the IC memory 8 from the transmitter / receiver 7 and sends them to the CPU 15, and conversely transmits the skill level information from the CPU 15 to the transmitter / receiver 7. ing.

The CPU 15 initializes the driving characteristics based on the discrimination of the ID code transmitted from the transmitting / receiving section 7 and the skill level information. If there is no skill level information on the memory card 1 side, the setting is predetermined such as for beginners.
Further, the driving pattern during traveling is monitored and quantified in a manner described later, and the skill level is determined based on the actual driving record.

The RAM 16 stores the information transmitted from the transmission / reception unit 7 and the quantified information of the driving pattern which changes during driving.

The EEPROM 17 stores various driving characteristic maps, as illustrated in the enlarged portion of the drawing. In this example, there are a front cylinder ignition timing characteristic a, a rear cylinder ignition timing characteristic b, an exhaust valve opening characteristic c, and a carburetor solenoid operating characteristic d of a V-type engine.

A plurality of patterns are prepared for each of the driving modes described later for these characteristic maps, and the CPU 15 selects and refers to the one corresponding to any one of the modes in accordance with the skill level to show the driving characteristics of the vehicle. Can be set. However, in the following description, only the control of the ignition timing characteristic will be referred to.

The types of operating characteristics to be controlled are not limited to the above, and can be arbitrarily increased or decreased. Further, these characteristic data can be stored in the IC memory 8 on the memory card 1 side.

2 and 3 show two preset ignition timing control modes. Mode 1 is for beginners, and controls changes in ignition timing to a minimum (Fig. 2),
As a result, the maximum output is not obtained, but the transient characteristics are set to be gentle (FIG. 3).

Mode 2 is an expert mode, and is controlled so that the ignition timing changes greatly (FIG. 2). As a result, peaky but maximum horsepower is obtained (FIG. 3). ).

Note that this mode is not necessarily in two stages, and as shown in FIG. 4, it can be set by subdividing into more modes (five stages in this example). In this example, the larger the number of modes from 1 to 5, the higher the skill level.

Next, a method of determining the skill level based on the accelerator opening will be described with reference to FIG. In this example, the skill level is determined depending on the number of accelerator operations for maintaining the accelerator opening of 80% or more for 3 seconds or more.
If the number of times of accelerator operation appears 5 times or more within the traveling distance within m, it is determined to be an expert, and if not, it is determined to be for beginners.

FIG. 5 shows a control method in the CPU 15. In this figure, first, when starting, it is monitored whether or not a case where the accelerator opening is 80% or more appears (S).
1) When it appears, it is measured whether this lasts for 3 seconds or more (S2-4).

When this condition is met, the appearance order N is increased by 1, and N and the current odometer distance L (N).
Is stored in the RAM 16 (S5), and the return number r is set to 1 and the skill level coefficient K is set to 0 (S6).

Next, from the present mileage L (N) to the past 1
It goes up to 00 Km to check whether or not a specific accelerator operation with an accelerator opening of 80% and for 3 seconds or more appears (S7), and each time it appears, the value of the skill level coefficient K and the return number r is incremented by one (S8, 9).

From the above, if the value of the skill level coefficient K is 5 or more within the past mileage of 100 km, it is determined that the user is a skilled person (S10), and the ignition timing is set to the mode 2 for the skilled person (S11). ).

On the other hand, if K is less than 5, it is determined that it is for beginners (S10), and the ignition timing is set to mode 1 for beginners (S12).

If the determined mode is different from the initial setting, the mode is updated to the latest one. The expert information determined at the same time is transferred from the transmitter / receiver 14 to the transmitter / receiver 7 of the memory card 1.
Sent to (S13) and IC memory 8 as skill level information
Is stored in At this time, if there is one stored earlier, it is updated.

Therefore, the driver quantifies the driving pattern on the basis of the accelerator opening degree by the CPU 15, so that the driver's driving skill is automatically discriminated as being for an expert or a beginner, and the boarding vehicle is automatically judged. The driving characteristics are set to match the driving skill.

Since the skill level information recorded in the memory card 1 is updated one after another, it means that the memory card 1 records the skill level based on the latest operation record.

Therefore, once the skill level information is recorded in the memory card 1, the driver only has to insert the memory card 1 into the card reader 2 and read the skill level information from the next run, and the driver can read the boarding vehicle. Can be automatically set to a driving characteristic suitable for one's driving skill.

Further, even when a plurality of drivers use one vehicle jointly, the vehicle is automatically set to the optimum driving characteristics for each occupant by creating a memory card for each person. .

Further, as shown in FIG. 4, if the mode setting is subdivided, the driving characteristics can be set more finely, and the skill level for improving the driving skill is improved, which is registered and updated in the memory card 1. Therefore, it is possible to set the vehicle so that the driving characteristics on the vehicle side seem to evolve as the driving skill grows, following the growth of the driving skill.

The invention of the present application is not limited to the above-described embodiment, but can be modified in various ways. For example, the determination of the driving skill can be made by using the deceleration G during braking as a parameter. In this case,
A person who is able to decelerate with G that is equal to or greater than a predetermined standard is determined to be an expert.

[0033]

According to the present invention, the control unit determines the skill level by determining the driving skill and the optimum driving characteristics can be set based on this skill level, so that the driving skill suitable for the driving skill of the driver can be obtained. It is possible to drive in a vehicle whose characteristics are automatically set.

In addition, since the skill level information determined based on the actual driving pattern is recorded in the memory card,
By reading the proficiency information stored in the memory card with a card reader prior to the start of traveling, the vehicle can be automatically set to the driving characteristics suitable for the driver's driving skill.

Therefore, even when a plurality of drivers share one vehicle, it is possible to drive with optimum driving characteristics for each person.
