In the brake control device for electric vehicles configured as described above, first, the brake command line (8) is passed from the brake controller (1) to the microcomputer (15) in the brake abnormality monitoring device (10A) and the electric brake force generator. A brake command representing the required service braking force amount is given to the device (17) and the air brake force generating device f (18), and is stored in the first storage means (151), and the necessary electric brake force and air brake force are generated. let The electric signals representing the electric brake force and the air brake force actually generated are stored in the second storage means (1
52) and stored in the third storage means (153). Next, when a brake abnormality detection command is issued from the brake controller (1) through the monitoring command line (3), the relay (7) is demagnetized and its a contact (7a) is turned OFF. At the same time, the brake abnormality detection command is sent to the brake abnormality monitoring device (IO).
A) OR circuit (
155c) K is also applied. The calculation means (154) is
The electric brake force amount stored in the second storage means (15F) in the adder (154a) and the third storage means (153)
The subtracter (154b) calculates the sum with the air brake force stored in the first storage means (154b).
1'lK The difference from the required brake force amount, which is the stored brake command, is taken. The amount of braking force shortage, which is the difference when the above-mentioned sum is smaller than the brake command, is compared with a predetermined level in the comparator (155a) in the comparison/output means (155), and in order to prevent malfunction due to transient fluctuations. It is determined by the ON timer (155b) inserted in the ON timer (155b) whether or not it continues for a predetermined period of time.

If the braking force shortage does not exceed a predetermined level, and even if it exceeds it, it does not continue for a predetermined period of time, the excitation continuation pulse continues to be output from the OR circuit (155c), so the excitation circuit (16) The abnormality detection relay (
11) continues to be energized and continues to close its a contact (11a2), and the emergency solenoid valve (6) continues to be energized, so that the emergency brake is not activated.

However, if the braking force shortage exceeds a predetermined level and continues for a predetermined period of time, the output of the excitation continuation pulse is stopped, so the excitation circuit (16) is no longer able to continue excitation. As a result, the abnormality detection relay (11) is demagnetized and opens its a contact (llaz). Therefore, the emergency solenoid valve (6) is also demagnetized, so
Emergency brakes are activated.

In addition, when the braking force shortage does not reach a predetermined level, the excitation continuation pulse continues to be output at fixed cycles.
The abnormality detection relay (11) can be kept in an excited state by the excitation circuit (16), so even if the A contact (7a) is open, the emergency solenoid valve (6) can be kept in an excited state by the A contact (llaz). Needless to say.
