Embodiment 1

[0045] figure 2 It is a structural schematic diagram of the trailer in the embodiment of the present invention, as figure 2 As shown, the present invention provides a trailer, including: a trailer chassis 1; also includes at least one drive axle 2, which is arranged on the bottom of the trailer chassis 1; also includes a motor 4 corresponding to the drive axle 2, each motor 4 Transmission connection with the drive axle 2 through the transmission shaft 5; also includes at least one battery 6, which is arranged on the bottom of the trailer chassis 1, and is electrically connected with the motor 4, and is used to supply power to the motor 4 and store the electric energy generated by the motor 4; also includes The electric control system 7 is arranged at the bottom of the trailer chassis 1 and is connected with the motor 4 signal, and is used to control the motor 4 to start and generate electricity.

[0046] When using the trailer, when braking, the electric control system 7 is...

Embodiment 2

[0050] continue to see figure 2 , the present invention also provides a tractor, including: a main vehicle, which includes a main control system, which is used to obtain the opening degree signal and the opening degree change rate signal of the accelerator.

[0051]Trailer, it comprises, trailer chassis 1, and it is connected with main vehicle through saddle; Also comprises at least one driving axle 2, and it is arranged on the bottom of trailer chassis 1; The motor 4 is connected to the drive axle 2 through the transmission shaft 5; it also includes a battery 6, which is arranged at the bottom of the trailer chassis 1, and is electrically connected to the motor 4, and is used to supply power to the motor 4 and store the electric energy generated by the motor 4; it also includes The electric control system 7 is located at the bottom of the trailer chassis 1 and is connected to the motor 4 and the main control system for receiving control signals from the main control system a...

Embodiment 3

[0057] The present invention also provides a control method for a tractor, comprising the following steps:

[0058] S1: Obtain the opening degree signals and the opening degree change rate signals of the accelerator pedal and the brake pedal respectively.

[0059] S2: According to the opening degree signals of the accelerator pedal and the brake pedal and the opening degree change rate signal, it is judged whether to enter the hybrid power mode or the braking mode. If entering the hybrid power mode, perform step S3, and if the braking mode, perform step S4.

Abstract

The present invention relates to the technical field of new energy vehicles, and specifically discloses a trailer, a tractor and a control method thereof. The method includes the following steps: S1: Acquiring the opening degree signal and the opening degree change rate signal of the accelerator pedal and the brake pedal respectively; S2 : According to the opening degree signals of the accelerator pedal and the brake pedal and the opening degree change rate signal, it is judged whether to enter the hybrid power mode or the braking mode. If entering the hybrid power mode, perform step S3, and if the braking mode, perform step S4; S3: According to the throttle opening signal and the opening change rate signal, combined with the SOC state of charge of the battery, the allowable discharge power and the state of the motor, the power assist power of the motor is adjusted through the electric control system; S4: according to the brake pedal opening signal and The opening change rate signal, combined with the SOC state of charge of the battery, adjusts the braking power of the motor through the electric control system. It can solve the problems of the growth of the power transmission chain of the whole vehicle and the increase of the moment of inertia of the engine.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a trailer, a tractor and a control method thereof. Background technique [0002] A hybrid vehicle, also known as a hybrid vehicle (Hybrid Power Automobile in English), refers to a vehicle equipped with more than two power sources: batteries, fuel cells, solar cells, and diesel locomotive generator sets. Currently, hybrid vehicles generally refer to diesel locomotives. Generator, plus battery for the car. The energy-saving and low-emission characteristics of hybrid electric vehicles have become one of the important ways to alleviate the current energy crisis and environmental pollution, and have made great progress in recent years. [0003] Different from traditional vehicles, hybrid vehicles are a complex electromechanical coupling system, as shown in Figure 1. On the basis of traditional vehicles, a drive motor 22 and a control system, a power battery and a control ...
