Embodiment Construction

[0018] A powertrain control system for hybrid electric vehicles, as shown in Figure 1 and Figure 2, the dotted line box in Figure 2 is the circuit schematic diagram of the three-phase full-wave rectifier unit and the high-voltage power distribution unit, and the rest is the corresponding circuit connected to it.

[0019] It includes a three-phase full-wave rectification unit 1, a high-voltage power distribution unit 2 and a vehicle central control unit 3, in which:

[0020] The three-phase full-wave rectification unit 1 includes three rectification modules 4, 5, 6, each module contains two diodes in series, and the three-phase AC output terminals of the generator are respectively connected to the AC input terminals of the three rectification modules. The three-phase full-wave rectification unit 1 performs full-wave rectification on the three-phase alternating current output by the generator to become a direct current power supply;

[0021] The high-voltage power distribution ...

Abstract

This invention relates to a power assembly control system used in mixed power electromotor including a three-phase commutation unit, a high voltage power distribution unit and an entire car central control unit, in which, the three-phase full wave commutation unit carries out full wave commutation to the three-phase AC current output by a generator to convert it to DC supply, the high voltage power distribution unit includes a DC output and test circuit, a power storage battery circuit, a motor supply circuit, an oil pump motor supply circuit, a gas pump motor supply circuit, an air conditioning supply circuit and an assistant power supply circuit, which is highly integrated and suitable for distribution in the car limit space.

Description

technical field [0001] The invention belongs to an automobile power control system, in particular to a power assembly control system for a hybrid electric vehicle. Background technique [0002] Today, there is a serious shortage of oil resources, and countries are working hard to develop the electric vehicle industry. As the current battery technology is still in a bottleneck state and has not made major breakthroughs, and the cost of hydrogen fuel cells remains high, the development of pure electric vehicles and fuel cell electric vehicles is still relatively restricted at present. For a period of time, the development prospect of hybrid electric vehicles is good, and it is expected to realize industrialization in the near future. As the name implies, the power source of a hybrid vehicle is provided by a mixture of various forms of energy, including the chemical energy of the power battery, the kinetic energy of the engine, the electrical energy of the generator, and the e...
