Embodiment 1

[0018] According to an embodiment of the present invention, an embodiment of a control system for a hybrid electric vehicle is provided.

[0019] figure 1 is a schematic diagram of a hybrid electric vehicle control system according to an embodiment of the present invention, such as figure 1 As shown, the system includes:

[0020] The battery manager 11 is used to detect the power remaining value of the power battery 13 .

[0021] Specifically, in the prior art, the traditional starter motor is powered by a storage battery with low power. In this application, a power battery with relatively high power is used for power supply.

[0022] In an optional solution, the battery manager can detect the power remaining value of the power battery in real time, and send the detected power remaining value to the hybrid controller.

[0023] The hybrid power controller 15 is connected with the battery manager 11, and is used to determine the operation mode according to the power remaining...

Embodiment 2

[0080]According to an embodiment of the present invention, an embodiment of a control method for a hybrid vehicle control system is provided. It should be noted that the steps shown in the flow charts of the drawings can be executed in a computer system such as a set of computer-executable instructions , and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0081] image 3 It is a flowchart of a control method of a hybrid electric vehicle control system according to an embodiment of the present invention, such as image 3 shown, combined with figure 2 As can be seen, the method includes the following steps:

[0082] In step S302, the hybrid power controller receives the power remaining value of the power battery detected by the battery manager.

[0083] Specifically, in the prior art, the traditional starter motor is powered by a storage battery with...

Embodiment 3

[0202] According to an embodiment of the present invention, a hybrid electric vehicle is provided, including any one of the hybrid electric vehicle control systems in Embodiment 1 above.

[0203] It should be noted here that the hybrid electric vehicle provided in this application includes various preferred and optional embodiments of the control system of the hybrid electric vehicle provided in Embodiment 1 above, but is not limited to the embodiment provided in Embodiment 1.

[0204] The serial numbers of the above embodiments of the present invention are for description only, and do not represent the advantages and disadvantages of the embodiments.

Abstract

The invention discloses a hybrid electric vehicle, a control system and a control method thereof. The control system of the hybrid electric vehicle comprises a battery manager for detecting an electric quantity remainder value of a power battery, a hybrid power controller connected with the battery manager and used for determining an operation mode according to the electric quantity remainder value of the power battery detected by the battery manager, a generator controller connected with the power battery and the hybrid power controller and used for receiving torque information for power generation sent by the hybrid power controller after the hybrid power controller controls the control system of the hybrid electric vehicle to enter an emergent power generation mode, and a generator connected with the generator controller and used for charging the power battery according to the torque information for power generation, wherein the operation mode comprises a pure electric mode, a hybrid power mode and the emergent power generation mode. The control system of the hybrid electric vehicle solves the technical problem of incapability of normal work of a hybrid power system under the condition of overlow battery electric quantity in the prior art.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a hybrid vehicle, a control system and a control method thereof. Background technique [0002] Hybrid electric vehicles include two main power sources of engine and motor. Compared with traditional engine vehicles, the energy utilization efficiency is higher and the emission performance is better. It has become a new type of vehicle and has broad application prospects. [0003] However, the current hybrid system mostly adopts the traditional starter motor solution, including the engine system and the motor drive system. The two systems can work in coordination at the same time, or they can work independently to drive the car, but they cannot meet the power generation problem in emergency situations; or adopt a series method , the engine drives the generator to generate electricity, the generated electric energy is transmitted to the battery through the control unit, and then the ba...
