場合に問題が生じる。 In such a known braking device (DE 2327508), a braking sensation imparting device, called a distance simulator or travel simulator, is combined with a master cylinder and connected to a brake conduit. This prevents the braking pressure from reaching its maximum value immediately after the pedal is depressed, and prevents the servo force from acting until the pedal is depressed to a certain extent. In high-end automobile brake systems, such a braking sensation imparting device is turned off for the brake conduit when a failure occurs in the servo brake system, and the braking medium pushed out from the master cylinder is thereby turned off. It is intended to be used exclusively for emergency braking without being supplied to the sensation-imparting device. In this case, the valve for turning off the brake sensation imparting device is controlled by the accumulator pressure or control pressure of the servo pressure generator. However, problems arise with such control schemes in extreme cases, for example when the servo pressure disappears and/or reappears during braking.
本発明の目的は制動感覚付与装置のオン・オフ
制御が常に確実に行われるようにすることであ

実に制御される。 In order to achieve this objective, the configuration of the present invention includes:
A braking sensation imparting device combined with the master cylinder is connected to the brake conduit, and is controlled on and off for the brake conduit by an electromagnetic device, and is turned on when the servo brake system is normal. , when a failure occurs in the servo brake system, it is turned off. Since the on/off control is performed electromagnetically rather than by pressure, the braking sensation imparting device can always be reliably controlled even if a serious failure occurs in the servo brake system.

When a fault occurs, the braking sensation imparting device is turned off, but even if the fault disappears again in a short time, it is not turned on while the pedal is depressed.

ら信号がインプツトされる。 When the brake pedal 2 is depressed, pressure is created in the tandem master cylinder 1. The braking sensation imparting device 7 allows the driver to reliably sense an increase in brake pressure. The brake pressure developed in brake line 5 is input by pressure measuring device 9 to electronic brake control 11 , where a comparison takes place and is converted into a switching signal for electromagnet 13 . In this case, the electromagnet 13 of the multiposition valve 12 is controlled via an output terminal which is also provided in the brake control device 11 .
Electronic brake control 11 receives an additional switching signal via conductor 27 and switch 26 in the event of a failure of servo pressure generator 17 . The electronic brake control device 11 cooperates with an electronic skid control device 25, by means of which the position of the multi-position valve 12 is controlled for skid control. A signal is input to the skid control device 25 from a wheel sensor (not shown).

リンダの制動圧力が減少せしめられる。 In this way, the multi-position valve 12 is used both for braking force boosting and for skid control. When there is no fault in the servo brake system, the master cylinder pressure only serves as a control pressure. The pressure increase in the wheel cylinders takes place after the pressures before and after the multi-position valve 12 have been compared electronically, optionally in conjunction with a signal from the position switch 28. The signal of the pressure measuring device 9 is then strengthened in accordance with the desired pressure increase.
The control pressure of the master cylinder 1 controls the electromagnet 13 of the multi-position valve 12 through an electronic device, and the control pressure of the master cylinder 1 is controlled by the electromagnet 13 of the multi-position valve 12.
2 supplies pressure from the servo pressure generator 17 to the wheel cylinder 6 until the desired braking pressure is generated in the wheel cylinder 6. When the control pressure from the master cylinder 1 is reduced, the multi-position valve 12 is switched to the fourth position and the braking pressure of the wheel cylinders is reduced.

７のブロツキングは解除されない。 In this case, the braking sensation imparting device 7 is blocked by electronic switching means in the electronic brake control device 11 and the skid control device 25. That is, even if the fault is stored electronically and disappears immediately, the blocking of the braking sensation imparting device 7 will not be released while the brake pedal 2 is depressed.

油を無駄に押し出すことがないようにしなければ
ならない。 Apart from this, if the control of the servo brake system is carried out electronically, it is necessary to be able to block the brake feel-imparting device in this way. This is because even if the servo pressure generator is normal, a failure may occur in the electronic control device or the energy supply system. For example, if there is no fault in the energy supply system and a fault is detected in the control device of the multi-position valve 12, the master cylinder 1 performs an emergency braking function, but in that case the braking sensation imparting device 7 is left in the OFF state. , it is necessary to prevent the master cylinder from pushing out braking oil unnecessarily.

Although the electromagnets 21 of the electromagnetic valve 20 and the electromagnet 21 of the electromagnetic valve 20 are controlled in parallel via the conducting wire 21, it is also possible to control both of these electromagnets separately.
