Abstract

The invention relates to the field of traffic facilities and particularly discloses an electric assisting pressurization control system for a hybrid electric vehicle engine. The electric assisting pressurization control system for the hybrid electric vehicle engine comprises a power battery pack, a first AC / DC converter, an ECU and an assisting energy storage unit, all of which are connected through a circuit. The ECU is further connected with a second AC / DC converter and a hybrid power motor through a circuit. The hybrid power motor, the second AC / DC converter and the assisting energy storage unit are sequentially connected through a circuit. A heat engine is pneumatically connected with an electric assisting turbocharger. A turbocharging assisting motor in the electric assisting turbocharger is connected with the first AC / DC converter through a circuit. The heat engine and the hybrid power motor are mechanically connected through a mechanical coupler. By the adoption of the electric assisting pressurization control system for the hybrid electric vehicle engine, under the condition that the turbocharger is not provided with a vent valve or a variable nozzle control system, the turbocharger is prevented from being blocked or surging, and the supercharging pressure is accurately controlled under any working condition. The response time can be shortened by about 50%.

Description

(1) Technical field [0001] The invention relates to the field of traffic facilities, in particular to an electric auxiliary supercharging control system for a hybrid vehicle engine. (2) Background technology [0002] Currently, in vehicles, devices of this type that require a power supply with a short response time include in particular: [0003] - a so-called "e-turbo" electrically assisted turbo-compressor, or a so-called "e-charger" supercharger, the device typically A power level of 1 to 2 KW for 1 to 2 seconds is required. These power levels and durations can be higher, but do not exceed 3KW and 3 seconds respectively. The response time of the power supply must usually be less than tens of milliseconds; [0004] - Electrically assisted steering units, which can draw 25 to 100A for 1 to 2ms under transient conditions; [0005] - an electric pump unit, which may require a current of about 100 A for about 200 ms; and [0006] - Solenoid controlled valve, which may req...
