Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for simulating the operation of a brake control device for controlling a braking force to an optimum state when braking a vehicle.

[0002]

2. Description of the Related Art Conventionally, a vehicle such as a scooter or the like is equipped with an ABS (anti-lock brake system) to stabilize a braking stop distance while preventing wheel lock to secure steering performance. .

[0003] In addition, since the brake operation of a scooter or the like often depends on the operation of the left lever (rear wheel brake) rather than the operation of the right lever (front wheel brake) based on the experience of riding a bicycle, the left lever is operated. A CBS that senses this input and generates braking force on both the front and rear wheels
(Combined brake system).

[0004] Such operation confirmation of the ABS and CBS is performed by, for example, actually running the vehicle when assembly is completed as a completed vehicle to evaluate its performance and feeling.

[0005]

Therefore, for example, ABS
Reaction force of the brake lever when the brake is actuated
Opportunities for experience such as are limited to those who actually drive, the experience range is narrow, and for example, for the durability test of the brake control device, etc., trying to repeat the same brake operation and repeating the same event many times However, road surface conditions and the like constantly change, and it is difficult to faithfully reproduce the event, and it is almost difficult to confirm the limit of durability by relying only on actual running.

Accordingly, the present invention provides a technique that allows the user to experience the feeling associated with the operation of the brake control device without actually driving the vehicle, and to perform a durability test under the same conditions as in actual driving. With the goal.

[0007]

In order to solve the above-mentioned problems, according to the present invention, in claim 1, a vehicle is actually driven to collect predetermined input / output data relating to the operation of a brake control device, and the input / output data is collected. A computer generates a simulated signal by processing, and the simulated signal is reproduced by a computer to simulate actual driving.

Then, a simulation signal is created by a computer such as a personal computer, and this data is stored as necessary, so that, for example, a brake control device of an arbitrary vehicle can be executed at an arbitrary place at an arbitrary time. The same phenomenon as running can be reproduced by a computer, and the performance, feeling, and the like can be evaluated without actually running the vehicle. Here, the brake control device is, for example, an ABS device of an automobile, or an ABS / CB of a scooter or a motorcycle.
Input / output data relating to the operation of the brake control device, for example, the brake operation amount, the wheel speed,
The operation amount of the ABS actuator and the like.

According to a second aspect of the present invention, the simulation result of the actual running is used for experiencing a behavior generated in the brake operation unit when the brake control device is operated. In this case, the brake control device is operated by a simulation signal created by a computer, and the reaction force (kickback) or the like generated in the brake operation unit by this operation is reproduced to give a real experience. Here, the brake operation unit is, for example, a brake pedal, a brake lever, or the like.

According to a third aspect of the present invention, a simulation result of actual running is used for a durability test of a brake control device. Then, a brake control device for a durability test is connected to a computer, and the brake control device is operated by a simulated signal to perform a durability test. At this time, since a certain simulated signal can be input and operation can be performed under the same conditions, a more reliable test can be performed.

The operation simulation method of the brake control device of the present invention is applied, for example, as an operation simulation method of a scooter ABS / CBS device. Before describing the present invention, first, an outline of the scooter ABS / CBS device is shown in FIG. It will be described based on.

In this scooter brake system, the front wheel 1 is of a hydraulic system and the rear wheel 2 is of a cable system, and a right cable damper 5 is arranged in the middle of a right cable 4 extending from a right lever 3 (front wheel brake).

The ECU 18 receives the stroke of the left lever 6. The operation of the ABS / CBS actuator 10 is controlled based on these. An indicator lamp 19 for notifying an abnormality of the control system is connected to the ECU 18.

The ABS / CBS actuator 10
Has a built-in motor (not shown) that can be rotated forward and backward by a control signal, and an electromagnetic brake (not shown) that performs a clutch function for operating the motor.
By operating the motor of the S actuator 10, the hydraulic pressure in the hydraulic pipe 12 is increased or decreased, and the pulling force of the cable 14 is adjusted to control the braking force.

The left and right cable dampers 5, 8 are AB
The reaction force (kickback) applied to each of the levers 3 and 6 when the S / CBS actuator 10 is operated is reduced, and a load switch is provided in each of the cable dampers 5 and 8. When the operation load of the left lever 6 reaches a predetermined value, the load switch in the left cable damper 8 operates the ABS / CBS actuator 10 to operate the hydraulic brake 13 of the front wheel 1 via the master cylinder 11. Like that.

In the above brake system,
When the brake is applied to the rear wheel 2 by operating the left lever 6, the load switch of the left cable damper 8 and the stroke sensor in the ABS / CBS actuator 10 confirm that
When a braking force is generated in conjunction with both the rear wheels (CBS) and one of the front and rear wheels is about to lock, the anti-lock brake system (ABS) is applied to the front and rear wheels by detecting the wheel speed sensors 16 and 17. ) Is activated.

Next, an example of input / output data relating to the CBS operation is as shown in FIG. That is, when the left lever 6 is input, the lever input load and lever stroke are measured by various sensors and the like, and when the load switch of the left cable damper 8 is operated, ON / OFF of the load switch is measured.

The ABS is activated by the operation of the load switch.
