Problems solved by technology
And in order to adapt to the small space of the low-floor vehicle, the hydraulic brake system does not have the same configuration as the air brake system, that is, there is no separate anti-skid control unit and anti-skid valve in the air brake system, so the braking of the air brake system is the same as that of the air brake system. The anti-skid mechanism cannot be applied to low-floor vehicles, so it is particularly important to design a braking and anti-skid solution suitable for low-floor vehicles

The application discloses a hydraulic braking method for a low-floor vehicle, which includes: receiving a braking command from a train and analyzing the braking command to obtain the current braking condition; according to the current braking condition, calculating the current braking condition as follows: The target value of the first hydraulic braking force of the car; determine whether to start the hydraulic brake anti-skid control; if not, control the electromagnetic valve in the electro-hydraulic control unit to perform hydraulic braking according to the first hydraulic braking target value; if so, correct the first A second hydraulic braking force target value is obtained from a hydraulic braking force target value, and the solenoid valve is controlled to perform hydraulic braking according to the second hydraulic braking force target value. The hydraulic braking method can not only meet the vehicle design requirements of the low-floor vehicle, but also realize anti-skid control, thereby improving the running safety of the low-floor vehicle. The application also discloses a hydraulic brake device, equipment and computer-readable storage medium for a low-floor vehicle, all of which have the above-mentioned technical effects.
Description
technical field [0001] The present application relates to the technical field of braking of low-floor vehicles, in particular to a hydraulic braking method for low-floor vehicles; it also relates to a hydraulic braking device, equipment and computer-readable storage medium for low-floor vehicles. Background technique [0002] At present, urban light rail vehicles, especially low-floor vehicles, have gradually become an important part of the urban traffic system because of their advantages such as fastness, convenience, and low pollution. Limited by the space of low-floor vehicles, the braking system of low-floor vehicles is mostly hydraulic braking system. Therefore, compared with the air brake system, the relevant components of the hydraulic brake system, such as the electronic brake control unit, the electro-hydraulic control unit, and the brake caliper, all adopt a small-volume design. And in order to adapt to the small space of the low-floor vehicle, the hydraulic brake...
