DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment will be described based on the drawings. FIG. 1 shows a memory card 1 and a card reader 2 constituting the control device of the present invention. The memory card 1 is a known card type key in which an IC memory unit 4 is built in a case 3 and a key 5 is removably attached to a corner portion.
[0007]
The IC memory unit 4 includes a power receiving coil 6, a transmission / reception unit 7, and a known IC memory 8, and the IC memory 8 is composed of various memories such as a CPU, ROM, and RAM.
[0008]
The memory of the IC memory 8 stores skill level information, which will be described later, and other information such as an ID code, if necessary.
[0009]
The card reader 2 incorporates a control unit 11 in a case 10, and a memory card 1 is inserted in a contactless manner above the control unit 11 with a socket 12 to which a power source, various sensors, signal lines, and the like are connected. Slot on the side.
[0010]
The control unit 11 includes a power transmission coil 13 that electromagnetically couples with the power receiving coil 6 to generate power on the memory card 1 side, a transmission / reception unit 14 that communicates with the transmission / reception unit 7 of the memory card 1, a CPU 15, a RAM 16, and an EEPROM 17.
[0011]
The transmission / reception unit 14 receives skill level information and ID codes stored in the IC memory 8 from the transmission / reception unit 7 and sends them to the CPU 15. Conversely, the CPU 15 transmits skill level information to the transmission / reception unit 7.
[0012]
The CPU 15 initializes the driving characteristics based on the identification of the ID code transmitted from the transmitting / receiving unit 7 and the skill level information. If skill level information does not yet exist on the memory card 1 side, it is set in advance for beginners. Further, the driving pattern during traveling is monitored and quantified as described later, and the skill level is determined based on the actual driving performance.
[0013]
The RAM 16 stores information transmitted from the transmission / reception unit 7 and quantified information of operation patterns that change over time during operation.
[0014]
Various operation characteristic maps are stored in the EEPROM 17 as illustrated in the enlarged portion in the figure. 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.
[0015]
These characteristic maps are prepared for a plurality of patterns for each driving mode, which will be described later, and the driving characteristics of the vehicle can be set by the CPU 15 selecting and referring to the one corresponding to one of the modes according to the skill level. However, in the following description, only the control of the ignition timing characteristic will be referred to.
[0016]
Note that the types of operation characteristics to be controlled are not limited to those described above and can be arbitrarily increased or decreased. Also, these characteristic data can be stored in the IC memory 8 on the memory card 1 side.
[0017]
2 and 3 show two types of preset ignition timing control modes. Mode 1 is a mode for beginners, and is controlled so that a change in the ignition timing is small (FIG. 2), and as a result, the maximum output cannot be obtained but the transient characteristics are gradual (FIG. 3).
[0018]
Mode 2 is a mode for skilled workers, and is controlled so that the change in ignition timing becomes large (FIG. 2). As a result, peak horsepower can be obtained (FIG. 3).
[0019]
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 (in this example, five stages). In this example, as the number of modes increases from 1 to 5, it corresponds to one that requires skill.
[0020]
Next, a method for determining the skill level based on the accelerator opening based on FIG. 5 will be described. In this example, the degree of skill is determined depending on the number of accelerator operations that are maintained for 3 seconds or more at an accelerator opening of 80% or more, and if the number of accelerator operations appears 5 times or more within the travel distance within the past 100 km, If not, it will be judged for beginners.
[0021]
FIG. 5 shows a control method in the CPU 15. In this figure, when starting, it is first monitored whether or not a case with an accelerator opening of 80% or more appears (S1), and if it appears, it is measured whether this lasts for 3 seconds or more. (S2-4).
[0022]
If this condition is met, the appearance order N is incremented by 1 and N and the current odometer distance L (N) are stored in the RAM 16 (S5), the return count r is set to 1 and the skill level coefficient K is set to 0 and each initial value is set. (S6).
[0023]
Subsequently, the current travel distance L (N) is reversed up to the past 100 km and the presence / absence of a specific accelerator operation with an accelerator opening of 80% and 3 seconds or more is checked (S7). The value r is incremented by one (S8, 9).
[0024]
From this, if the value of the skill level coefficient K is 5 or more within the past travel distance of 100 km, it is determined that the person is an expert (S10), and the ignition timing is set to the mode 2 for the expert (S11).
[0025]
Conversely, if K is less than 5, it is determined for beginners (S10), and the ignition timing is set to beginner mode 1 (S12).
[0026]
If this determined mode is different from the initial setting, it is updated to the latest one. The expert information determined at the same time is sent from the transmitter / receiver 14 to the transmitter / receiver 7 of the memory card 1 (S13) and stored in the IC memory 8 as skill level information. At this time, if there is something stored earlier, it is updated.
[0027]
Therefore, the driver quantifies the driving pattern based on the accelerator opening by the CPU 15, so that his / her driving skill is automatically discriminated as an expert or a beginner, and the boarding vehicle automatically becomes his / her driving skill. Appropriate operating characteristics are set.
[0028]
Skill information recorded in the memory card 1, since it is sequentially updated after them, so that the proficiency based on the latest operation records are recorded in the memory card 1.
[0029]
Therefore, once the skill level information is recorded on the memory card 1, from the next run, the driver simply inserts the memory card 1 into the card reader 2 and reads the skill level information. The driving characteristics can be automatically set according to the driving skill.
[0030]
Furthermore, even when a single vehicle is shared by a plurality of drivers, by creating a memory card for each person, the vehicle is automatically set to optimal driving characteristics for each occupant.
[0031]
Also, as shown in FIG. 4, if the mode setting is subdivided, the driving characteristics can be set finely, and the skill level is improved for improving the driving skill, which is registered and updated in the memory card 1. Following the growth of the driving skill, it is possible to make settings that make it appear as if the driving characteristics on the vehicle side evolve as the driving skill grows.
[0032]
The invention of the present application is not limited to the above-described embodiment, and can be variously modified. For example, the determination of the driving skill can be performed by using the deceleration G at the time of breaking as a parameter. The case where the vehicle can be decelerated with G is determined as an expert.
[0033]
【The invention's effect】
According to the present invention, the control unit determines the ripe proficiency based on information satisfies a predetermined condition among the information quantifying the driving technique, it is possible to set the optimum driving characteristics based on the skill level, driving It is possible to run with a vehicle that is automatically set to the driving characteristics that match the driving skill of the person.
[0034]
Further, information that satisfies the predetermined condition is stored in a storage unit, and information that satisfies the predetermined condition in a predetermined travel distance section that goes back to the past from when the information that satisfies the predetermined condition appears after the start of traveling. Since the skill level is determined on the basis of the number of appearances, the optimum driving characteristic suitable for the driving skill of the driver can be set more accurately and automatically.
