1. Name
Hybrid
2. Introduction
The hybrid vehicle has an electric motor as an auxiliary power of the engine driving the vehicle.
high fuel economy of hybrid vehicles, and excellent driving performance, hybrid car engines to use fuel, but also in starting, acceleration, due to the auxiliary electric motor, it is possible to reduce fuel consumption, simply put, it is compared with the same size cars, lower fuel costs.
Moreover, the electric motor assists the engine can produce a powerful force at the moment of launch, so the owner can enjoy a more robust start to accelerate. At the same time, fuel economy can achieve a higher level of
kind of hybrid cars present, there are three kinds. One is the main power of the engine, an electric motor as an auxiliary power “in parallel.” In this way the main engine running, characterized by using a strong power of the restart of the electric motor has, the larger consumption of automobile starting, acceleration, engine fuel, the electric motor assist drive mode to reduce fuel consumption of the engine. In this way the structure is relatively simple, only need to add an electric motor and battery in the car. Alternatively, the electric motor driven drive alone at low speed, when the engine speed increases and the electric motor drive cooperating “series, in parallel.” Starting and low speed travel is driven only by the electric motor, when the speed increases, the engine and the electric motor together efficiently share power, this approach requires a power sharing apparatus and generators, and therefore a complicated structure. Another electric motor is driven only with the electric vehicle “in series”, only the engine as a power source, the electric motor car drive travel alone, only the electric motor drive system, but also need to install because the engine fuel, it is also a hybrid a motor vehicle.

The hybrid system is divided into threeCategories: serial, parallel, and hybrid. Corresponding to the engine in series form only act as a generator, it is only required for the travel operation of the power supply of the vehicle, the current hardly used. Two parallel hybrid coordination system either simultaneously, the work may be individually driven cars. This system is suitable for a variety of different driving conditions, especially for complex road. And includes a simple structure and low cost. Honda is currently the main use.
Hybrid hybrid system is characterized by a set of each of the mechanical transmission mechanism and the motor drive system of the engine system, or two bodies joined together by a gear train or a planetary wheel structure, thereby regulating the engine integrated the relationship between the rotational speed and the motor. Compared with the parallel hybrid system, hybrid type power system can be more flexibly adjusted according to operating conditions and the motor power output of the engine. This way linking system complexity, high cost, the key is the use of Toyota.
