[Prior art] In recent years, in response to the demand for improved vehicle running safety, a system has been developed based on the rotational speed of the driving wheels (hereinafter referred to as driving wheel speed) and the rotational speed of the driven wheels (hereinafter referred to as driven wheel speed). A vehicle that determines whether or not the drive wheels are in a slip state, and when it is determined that the drive wheels are in a slip state, controls the torque transmitted to the drive wheels to prevent slips. Various anti-slip devices have been proposed. Several methods are known for determining whether or not these devices are in a slip state. J, or whether the ratio of the driving wheel speed to the driven wheel speed exceeds a predetermined value. It's too late. In addition, in order to control the torque transmitted to the drive wheels, methods are used to directly control the engine torque by controlling the ignition timing and fuel supply, and methods to control it by using a torque transmission mechanism. It was also there.

However, there are demands from drivers who have acquired sophisticated driving skills to maximize the driving performance of the vehicle such as drifting and spin turns that actively utilize the slip of the drive wheels. There is a possibility that you will have to stop for danger avoidance, and you will be required to drive into Drift 1 or make spin turns.
There was a problem in that vehicles equipped with conventional anti-slip devices were unable to respond.

The judgment at step 100 is "Y"s", that is, switch 3

Ru. The switch 4 is one of the allowable range changing means for slip control, and is used to change the driving wheel speed Vf and the driven wheel speed Vf.
When the speed difference Vf-Va with A exceeds it, it is determined that the ship is in a slip state. .1 is defined so that the range of V[capacity] is increased. Switch 4 is ON (1) 1lij, -)

When the determination at 0 is rNOJ, the process moves to step 150, where Δv is set to 2xva and a variable ΔV representing the T YI tolerance range is created. Here, since k + :>k 2, when switch 4 is ON, △V will be turned white and the other person will be turned on. After the processing in step 1/lo or step 150, the control moves to step 160, where the speed difference between the driving wheel speed Vf and the driven wheel speed va is calculated and created in the preceding step. It is judged whether or not the filling is within △V.The judgment 117i at step 160 is rNOj, that is, Vf-Va.
When ≦△V does not hold, the speed difference between the driving wheel speed J and the driven wheel speed va is not within the allowable range, and the driving wheel is judged to be slipping, so the control is Step 1
70, and outputs the fuel signal to the fuel supply device M6. After that, step 1.
Proceeding to 90, an alarm signal is sent to the alarm device 7. Through the processing in step 170, the fuel supply device i\6 moderately or suppresses the supply of fuel to the engine, thereby reducing the 1-lux transmitted to the drive wheels by reducing the engine 1 herk, thereby reducing the slippage. prevent the occurrence of Also, step 190
As a result of this process, the driver is notified by the warning device 7, for example, by lighting the lamps mounted on the instrument panel 1 or by making a beep sound, n) that the vehicle is slipping. If no slip occurs, or after slip occurs, the above-mentioned steps 170...190 are performed and one of the drive wheels is
- As the torque decreases, the driving wheel speed Vf and the driven wheel speed 1
If the speed difference with a becomes sufficiently small, step 160
The judgment is that IYESJ, that is, Vf-Va≦△V holds true. At this time, driving wheel speed V [and driven wheel speed V
It is determined that the speed difference with a is within the allowable range,
Since the drive wheels are no longer considered to be in a slip state, the control moves to step 1.80 and resets the output of the fuel cut signal to the fuel supply device 6 or maintains the state in which the signal is not output. After performing the processing, the process proceeds to step 200, and processing is performed to cancel the sending of the alarm signal to the alarm device 7 or to maintain the state in which the signal is not output. Through the process of step 180, the amount of fuel supplied to the engine returns to a state where no slip control is performed, the 1 to 1 torque transmitted to the drive wheels is not suppressed, and the slip control υ11 is canceled. Since the output of the warning signal is reset by the process of step 200, the driver can know that the slip control has been canceled or that the slip control is not being performed.

In this embodiment, two manual switches were used as the means for changing the illumination, but in order to achieve the purpose of this investigation, it is acceptable to use only one manual switch. In addition, the switch for setting the large/small allowable range may be a multi-stage switch, or may be set steplessly using a variable resistor or the like. For people in the γ1 volume range, the occurrence of slips is a factor that tends to make the vehicle's running more unstable (for example, it is thought that the driver will often set it due to rain, etc., so this is a means to change the allowable range. Activate the wiper with the manual switch of I) J1'? It is preferable to use the switch also as a switch because switching can be done easily and the number of parts can be reduced.

Further, in this embodiment, the allowable range is calculated as a value proportional to the driven wheel speed Va, but it may be a predetermined value, or it may be calculated as a specific function of the driven wheel speed. good. !・In this embodiment, a fuel supply device is used as the torque control means to control the engine torque.
The torque control means may be replaced with engine torque control using ignition timing control, air-fuel ratio control, etc., or an electromagnetic clamp or the like may be installed to cut off the torque transmitted to the drive wheels. Since it is not possible to change the means, a suitable configuration can be selected depending on the vehicle to which the anti-slip device is applied. Furthermore, although the control routine of this embodiment is a closed loop that only performs slip control, other control routines using a combi coater, such as ignition timing control, are used as the main routine, and from there, the engine is controlled at a predetermined crank angle (for example, The control routine shown in FIG. 3 of this embodiment is started from A at the crank angle interrupt, which is configured to occur every
The main routine may be returned to after the completion of 00, thereby reducing the number of parts. In addition, in this embodiment, step 100 performed at the beginning of the control routine is replaced by step 160 and step 1.
70, and when the switch 3 is OFF, step 170 is not executed and the process moves to step 190. Moderate control such as outputting η is possible without changing the gist of the present invention.

[Effect of the invention 1] The slip prevention device for the center shaft of the present invention detects the driving wheel speed and the driven wheel speed, and determines whether or not there is a slip condition C from the speed difference between the two wheels. The system is equipped with a tolerance range changing means for changing the driving wheel, and determines whether the slip state is present based on the difference in power of the two wheels and the set/changed tolerance range, and controls the torque transmitted to the drive wheels. The vehicle is configured to carry out slip control.

Therefore, it is possible not only to perform normal slip control, but also to cancel slip control in response to the driver's request to maximize the driving performance of the vehicle, and change the state of slip control depending on the situation. It has the excellent effect of being able to cover a wide range of driving performance requirements.
