The invention relates to a turbocharging system, a turbocharging method and a vehicle. The turbocharging system comprises an air intake system, an air brake system, a turbocharger and a controller; the air outlet end of the air intake system is connected with the turbine end of the turbocharger; the air brake system comprises an air compressor, a gas storage portion and a brake actuation portion,and the air intake end of the air compressor is connected with the air outlet end of the air intake system; the air outlet end of the air compressor is connected with the air outlet end of the gas storage portion; one path of the air outlet end of the gas storage portion communicates with the brake actuation portion selectively, and the other path of the air outlet end of the gas storage portion communicates with the turbine end of the turbocharger selectively; and the controller is used for controlling air in the gas storage portion to lead to the turbine end of the turbocharger when the vehicle speed is lower than the preset speed. In this way, when an engine works under the low-speed working condition, high pressure gas stored in the gas storage portion can be led to the turbocharger for supercharging a turbine, so that the turbocharger can still obtain higher speed when the engine speed is lower, and the low speed supercharging performance is improved.
本公开涉及一种涡轮增压系统、涡轮增压方法以及车辆,其中涡轮增压系统包括进气系统、气刹制动系统、涡轮增压器及控制器;进气系统的出气端与涡轮增压器的涡轮端连接;气刹制动系统包括空压机、储气部及制动执行部,空压机的进气端与进气系统的出气端连接,空压机的出气端与储气部的进气端连接;储气部的出气端一路与制动执行部选择性连通,另一路与涡轮增压器的涡轮端选择性连通;控制器用于在车辆的速度低于预设速度时控制储气部中的空气导向涡轮增压器的涡轮端。这样,当发动机处于低速工况时,储气部内储存的高压气体能够导向涡轮增压器,以对涡轮增压,使涡轮增压器在发动机转速较慢时仍能获得较高的转速,改善低速增压性能。
