FIG. 4 is a diagram showing a relationship between a conventional vehicle speed sensor, an electronic control unit, and an instrument. As shown in FIG. 4, the rotation of the crankshaft 8 of the engine 3 is transmitted to the transmission 1 and is appropriately reduced to rotate the rear axle shaft 28 via the drive shaft 27 and the differential gear 7.

【発明が解決しようとする課題】ＪＩＳ規格によれば、

が６３７回転していることが規定されている。According to the JIS standard,
It is stipulated that the speed meter indicates 60 km / h when the shaft 24 rotates at 637 rpm. That is, when traveling 1000 m, the shaft 24
Is specified to rotate 637 times.

リブンギア比＝６３７ となることが必要である。このため、通常は、ドリブン
ギア比を調整することにより上式を満足させている。Here, the radius of the tire is defined as r, and 1000
In order for the shaft 24 to rotate 637 when traveling m, it is necessary that (1000 / 2πr) × differential gear ratio × driven gear ratio = 637. Therefore, usually, the above equation is satisfied by adjusting the driven gear ratio.
【０００７】上式によれば、タイヤの径が異なる車種毎

なる多種類の変速機を用意しておかなければならず、そ
の管理に手間がかかってしまうことが問題となる。According to the above equation, it must be understood that it is necessary to change the driven gear ratio for each vehicle type having a different tire diameter or for each vehicle type having a different differential gear ratio. Therefore, it is necessary to prepare various types of transmissions having different driven gear ratios, and there is a problem that management of the transmissions is troublesome.

出力に補正を行い、所定の車速信号を得る方法も行われ
ている。FIG. 5 is a diagram showing a conventional example using a vehicle speed conversion device. As shown in FIG. 5, the driven gear ratio is kept constant, and the output of the vehicle speed sensor 4 is output using the vehicle speed conversion device 50. A method of performing correction and obtaining a predetermined vehicle speed signal has also been performed.
【０００９】この車速変換装置５０の補正出力を計器６
の車速信号入力として用いることにより、多種類の変速
機を管理する必要がなくなるため、この方法は優れた方
法であるといえる。The correction output of the vehicle speed conversion device 50 is
This method can be said to be an excellent method because it is not necessary to manage various types of transmissions by using the vehicle speed signal as an input.
【００１０】しかし、車速変換装置５０では、車速セン
サ４から出力される車速信号を所定の車速信号に変換す

因する変換遅れ時間が発生する。However, since the vehicle speed conversion device 50 performs a correction operation for converting the vehicle speed signal output from the vehicle speed sensor 4 into a predetermined vehicle speed signal, a conversion delay time due to the calculation time occurs. .
【００１１】したがって、この車速信号を電子制御装置
５に使用することには問題がある。例えば、ＡＢＳ(Ant

制動制御を行う必要がある。このような場合には、変換
遅延の許容時間はごくわずかであり、車速変換装置５０
を経由した車速信号をＡＢＳに適用することはできな
い。Therefore, there is a problem in using the vehicle speed signal for the electronic control unit 5. For example, ABS (Ant
Looking at the ilock Braking System, the vehicle speed changes very quickly in a very short time when the brake is applied suddenly. This vehicle speed signal is taken into the electronic control unit in real time,
It is necessary to perform braking control. In such a case, the permissible time of the conversion delay is very short, and the vehicle speed conversion device 50
Cannot be applied to the ABS.

理に手間がかかってしまう。Alternatively, one method is to make the vehicle speed conversion device 50 a high-performance device whose correction output can be used as an input of the electronic control device from the beginning. However, the type of electronic control unit varies depending on the vehicle model,
Some vehicles do not use an electronic control unit. Therefore,
It is not advisable to mount the expensive high-performance vehicle speed conversion device 50 on all types of vehicles from an economic viewpoint. In addition, if the vehicle speed conversion device 50 having a different calculation speed is installed for each vehicle type, various types of vehicle speed conversion devices are prepared, and the management of the transmission becomes similar to the case where the above-mentioned transmissions become many types. Takes time and effort.
