Problems solved by technology

[0003] However, in the relevant technologies known to the inventor, some hybrid electric vehicles have few driving modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is fed (when the battery power is insufficient). Insufficient vehicle power and passing capacity
Moreover, in order to realize the parking power generation condition, it is necessary to additionally increase the transmission mechanism, which has low integration and low power generation efficiency

Abstract

The invention discloses a power drive system of a vehicle and the vehicle with the same. The power drive system of the vehicle comprises a power source, a first electric generator unit, a system poweroutput part and a mode conversion device, wherein the mode conversion device comprises a conversion device input part and a conversion device output part, the conversion device input part is selectively in dynamic coupling with the power source, the conversion device input part is in dynamic coupling with the first electric generator unit, the conversion device output part is fixed to a shell ofthe system power output part, the conversion device input part is selectively connected with the conversion device output part, and when the conversion device input part and the conversion device output part are disconnected, the power source is suitable for directly driving the first electric generator unit to generate power. The power drive system has many working modes, and particularly under aparking power generation mode, the functions of the vehicle are greatly enriched; meanwhile, the power source is suitable for directly driving the electric generator unit to generate power, and the drive efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of transmission, and in particular relates to a power transmission system of a vehicle and a vehicle with the power transmission system. Background technique [0002] With the continuous consumption of energy, the development and utilization of new energy vehicles has gradually become a trend. As one of the new energy vehicles, a hybrid vehicle is driven by an engine and / or an electric motor, and has multiple modes, which can improve transmission efficiency and fuel economy. [0003] However, in the related technologies known to the inventor, some hybrid electric vehicles have few drive modes and low drive transmission efficiency, which cannot meet the requirements of the vehicle to adapt to various road conditions, especially after the hybrid electric vehicle is powered (when the battery power is insufficient). The power and passing capacity of the whole vehicle are insufficient. Moreover, in order to rea...
