Hybrid power control system and method for vehicle

Abstract

The invention provides a hybrid power control system and method for a vehicle, and relates to the field of vehicle engines. The hybrid power control system comprises a vehicle control unit, a power distribution system, a power battery and an engine. The engine comprises a plurality of coil groups and a plurality of magnetic pistons. Each coil group is connected with the power battery and is used for receiving the adjustment of the power distribution system to charge the power battery. The multiple magnetic pistons are arranged in the coil sets in a one-to-one correspondence mode, and a movingmagnetic field formed by cutting the magnetic pistons through the closed coil sets generates electricity to charge the power battery. The vehicle controller is configured to control the power batteryand / or the engine to drive the vehicle according to the running speed of the vehicle and the electric quantity of the power battery, and selectively control the power distribution system to distributepower for charging the engine to drive the vehicle and the power battery according to the electric quantity of the power battery. According to the scheme, energy loss caused by energy conversion canbe effectively avoided.

Description

technical field [0001] The invention relates to the field of vehicle engines, in particular to a hybrid control system and method for vehicles. Background technique [0002] With the continuous improvement of national environmental protection requirements, the control of vehicle fuel consumption is becoming more and more stringent. my country has implemented the fourth phase of passenger car fuel consumption standards in 2016. In 2020, it is planned that the average single vehicle fuel consumption of passenger car companies will be reduced to 5L / 100km, the average fuel consumption of passenger cars in new cars will drop to 4.0L / 100km in 2025, a drop of 20% compared to 2020, which will put a lot of pressure on passenger car companies. In order to achieve this goal, domestic automobile companies of all sizes have begun to develop new energy vehicles. New energy vehicles are mainly divided into series hybrid, parallel hybrid, hybrid hybrid and pure electric vehicles. The fuel co...

AI Technical Summary

Problems solved by technology

The series hybrid engine can work at the best power-to-fuel consumption ratio position, reduce frequent fluctuations in engine power, and avoid the engine working under poor fuel-to-power ratio conditions, but the series hybrid needs to convert fuel chemical energy into Electrical energy, electrical energy is converted into mechanical energy, the energy conversion twice, the overall efficiency will be reduced

The working conditions of the parallel hybrid or hybrid hybrid engine cover a wide range, which cannot guarantee that the engine will always work in the best working condition, and the structure is complex and costly
