Abstract
The invention discloses a high-pressure brake assisting control system of an electric motor coach. The high-pressure brake assisting control system of the electric motor coach comprises a booster, a high-pressure gas storage tank, a pressure sensor, an electric air compressor unit and a master control ECU. The electric air compressor unit integrates a motor driver based on a power battery, a permanent-magnet synchronous motor and a sliding-vane air compressor. When a brake pedal is stepped on, the high-pressure gas storage tank outputs high-pressure gas to the booster, so that brake assistance is formed to assist in braking of the electric motor coach. According to the high-pressure brake assisting control system of the electric motor coach, since the motor driver based on the power battery, the motor and the air compressor are integrated, the appearance size of the whole control system is greatly reduced, the number of power cables and connectors in use is reduced, the safety risk of the electric motor coach is lowered, and the space of the electric motor coach is saved; due to the fact that the permanent-magnet synchronous motor is used for replacing a three-phase asynchronous motor, noise in the electric motor coach is lowered, efficiency is high, energy is saved, and the service life of the whole control system is greatly prolonged.
