Embodiment Construction

[0018] Such as figure 1 and Figure 4 As shown, the vehicle hybrid four-wheel electric drive system of the present invention includes an engine, an engine controller, an integrated controller, a generator, a rectifier, a power battery pack, a charging and discharging device, and four inverters and four A traction motor controller. The integrated controller is internally composed of a voltage stabilization control unit, a battery charge and discharge control unit, electric energy braking control, driving mode switching control and an integrated control unit. The integrated controller is respectively connected to the engine control unit through the CAN bus. Controller, charging and discharging device and each traction motor controller and monitor their status and control the energy supply and demand and power distribution of the entire electric drive system in time, the integrated controller is equipped with a control switch, and the integrated controller is connected to the rem...

Abstract

The invention provides a vehicle hybrid four-wheel electronic drive system, which comprises an integrated controller respectively connected with a motor controller, a charge-discharge device and all the controllers of traction electric machines through a CAN bus and controls in-time energy supply and demand, and power distribution of the whole electric drive system. The invention has the advantages of both a four-wheel drive and the eclectic drive system, thereby solving the problem of insufficient driving range. The integrated controller saves the traditional machinery differential mechanismthrough an electronic differential control algorithm, can realize vehicle steering with optional radiuses without the function of a machinery transfer device, enables the vehicle to move freely through remote control under the condition of driving without a driver, widens the application range of the vehicle, can reach the best dynamic property by adopting the best fuel oil consumption control method, and introduces a power ring besides the double closed loop control structure of velocity and current, so as to ensure that the whole system is stable during working and has ideal pulling figure.

Description

technical field [0001] The invention relates to the technical field of vehicle drive, in particular to a vehicle hybrid four-wheel electric drive system. Background technique [0002] The drive system of the vehicle has developed from the traditional rear drive to the direction of multi-wheel drive, among which the development of four-wheel drive technology is the most typical. The four-wheel drive technology of the vehicle can control and distribute the driving force of the front and rear axles according to the information such as the speed of the front and rear axles. With the continuous progress of research in this field, a variety of practical systems with different structural forms and different control schemes have emerged; if classified according to the working time of four-wheel drive, it can be divided into full-time four-wheel drive and part-time four-wheel drive , If classified according to the front and rear torque distribution methods, the full-time four-wheel ...
