Problems solved by technology
When the drain valve is opened to drain water, if there is high-pressure gas passing through the condenser assembly, a large amount of water vapor will be ejected from the drain valve, and the drainage effect is better. If there is no high-pressure gas passing through, the water in the valve will be drained downward by its own weight, and the drainage effect will be better. Often poor, condensed water remains
Therefore, the condenser drainage strategy in the related art often leads to more condensed water remaining in the condenser, which may affect the life of the condenser and even affect driving safety.

The invention discloses a condenser control device of a braking system, a vehicle braking system and a vehicle, and the condenser control device comprises a condenser drain valve, a condenser control device and a controller, the first switch is set to open the condenser drain valve under the condition that the first switch is switched on; and the drainage control module is used for detecting the unloading pressure of a gas circuit of the braking system and outputting a first conduction control signal for controlling the first switch to be conducted based on the unloading pressure. When unloading is carried out, the drain valve is opened to drain water, meanwhile, high-pressure airflow must flow through when the drain valve of the condenser is opened to fully drain water, high-pressure airflow flows through the condenser as little as possible after the drain valve is closed, condensate water is prevented from being collected again, and less condensate water remains in the condenser.
Description
technical field [0001] The present disclosure relates to the technical field of vehicles, in particular to a brake system condenser control device, a vehicle brake system and a vehicle. Background technique [0002] The vehicle braking system is to make the driving vehicle decelerate or even stop forcibly according to the driver's request, or to make the stopped vehicle stably park under various road conditions, or to keep the downhill vehicle at a relatively stable speed. [0003] At present, more and more vehicles, especially large vehicles or pure electric vehicles, use pneumatic brake systems. Some vehicles use condensers in the brake pipeline, and the high-pressure gas discharged from the air compressor passes through the condenser. When it is condensed and some moisture is retained, the high-pressure gas is supplied to the gas storage tank after passing through the dryer, so that the high-pressure gas provided to the system is cooled and drier. The condensed water tra...
