Abstract

The present invention relates to a brake system, comprising: a brake system in which a front wheel left brake and a rear wheel right brake are connected by a first pipe, and a front wheel right brake and a rear wheel left brake are connected by a second pipe. The pipe is characterized in that the operation means using the torque of the electric motor is mounted so that it can transmit the steering force in the opposite direction of rotation of the vehicle when the pipe bursts.

According to the present invention, when the brake line of the vehicle is ruptured, the torque of the electric motor is adjusted to induce steering in the opposite direction of rotation when the vehicle tries to rotate regardless of the driver's intention to stabilize the vehicle.

Description

Brake system using electric motor torque {Brake system}

The present invention relates to a brake system, and more particularly, in order to prevent one of the hydraulic pipes from rupturing and turning the vehicle to one side during braking, a vehicle is rotated by installing an operation means using electric motor torque in front or rear of the vehicle. It relates to a brake system using electric motor torque to induce steering in the opposite direction.

In general, a brake device of a vehicle is a device that reduces or stops the speed of a running vehicle. The brake generally uses a frictional force generated by a driver's operation force or an auxiliary power to convert a kinetic energy of a vehicle into thermal energy to perform a braking action. It works in a way that causes it.

1 shows a pipe connection structure of a brake system of most passenger cars, in which the brake system 100 is connected to a front pipe left brake 220 and a rear wheel right brake 340 by one pipe 420 through an X pipe. The front wheel right brake 240 and the rear wheel left brake 320 are connected to the other pipe 440.

Such a brake system is characterized in that the force generated by the brake is not directed to one side even if one pipe is ruptured.

However, the brake system as described above has a problem that left and right braking forces are unbalanced due to a difference in braking radius between the front wheel and the rear wheel and the braking radius of the brake disk in a situation in which one pipe is ruptured, thereby causing the vehicle to rotate.

The present invention has been made in order to solve the above problems, one of the hydraulic pipe is ruptured to prevent the phenomenon of turning the vehicle to one side during braking to install the operation means using the electric motor torque in the front or rear of the vehicle It is an object to provide a brake system using electric motor torque which induces steering in the opposite direction of rotation.

In order to achieve the above object, in a brake system in which a front wheel left brake and a rear wheel right brake are connected to a first pipe, and a front wheel right brake and a rear wheel left brake are connected to a second pipe, between the front wheel left brake and the front wheel right brake. When the pipe ruptures it is characterized in that the operating means using the torque of the electric motor is mounted so as to transmit the steering force in the opposite direction of rotation of the vehicle.

According to the present invention, when the brake line of the vehicle is ruptured, the torque of the electric motor is adjusted to induce steering in the opposite direction of rotation when the vehicle tries to rotate regardless of the driver's intention to stabilize the vehicle.

Hereinafter, the configuration of the present invention with reference to the accompanying drawings, Figure 2 is a rear view showing a brake system according to the present invention, Figure 3 is an algorithm showing a brake system according to the present invention.

In the brake system 10 of the present invention, the front wheel left brake 22 and the rear wheel right brake 34 are connected to the first pipe 42, and the front wheel right brake 24 and the rear wheel left brake 32 are connected to the second pipe ( 44).

The vehicle rotates when the pipes 42 and 44 are ruptured between the front wheel left brake 22 and the front wheel right brake 24 or between the rear wheel left brake 32 and the rear wheel right brake 34 or both sides of the front wheel and the rear wheel. The operation means 50 using the torque of the electric motor is mounted so that the steering force can be transmitted in the opposite direction.

Here, the operation means 50 may be made in various configurations, but in the present invention, the hydraulic pressure in the interior according to the operation of the electric motor is transmitted in one direction to the front wheel left brake 22 or the front wheel right brake 24. An example consisting of will be described.

And the operation means 50 using the torque of the electric motor is operated by the signal transmitted through the process as shown in FIG.

First, the master cylinder pressure, the wheel speed, and the HU valve signal input to the electro-hydraulic braking device S10 are received to calculate the pressure value S20 of the individual brake chamber.

In the above state, the braking force is calculated (S30) to calculate the rotation moment value (S40), or the braking force is calculated (S30), and pipes 42 and 44 are inspected for bursting (S30 ?? 1). The rotational moment value S40 is calculated by determining the rotational direction according to the rupture of the first pipe 42 or the second pipe 44 (S30 ?? 2).

Next, the rotation moment value S40 is recognized to calculate the value S50 that cancels the rotation moment value S40 and the steering angle corresponding thereto is calculated and transferred to the electric motor.

And by operating the operation means 50 according to the signal transmitted to the electric motor is to transmit the steering force in the opposite direction of the rotation of the vehicle to prevent the vehicle from rotating.
