Abstract

A control method for improving the braking energy recovery of the car with mixed power features that when the car is braked for deceleration, the engine is separated from power drive system by clutch and the electric generation load of electric generator is increase by recovering the braking energy.

Description

Improve the control method that the hybrid vehicle braking energy reclaims
Technical field:
The present invention relates to the control method of hybrid power automobile power system, particularly relate to a kind of control method that the hybrid vehicle braking energy reclaims that improves.
Background technology:
Along with becoming increasingly conspicuous of global environment and energy problem, the new automobile of exploitation anti-emission carburetor, low oil consumption becomes the top priority of current automobile industry development.The mixed power electric car technology has been avoided the deficiency of pure electric automobile on battery technology and energy Infrastructure, is a good solution of current problem, has become the focus of current international automobile research and development.
Utilizing electric power generation to reclaim braking energy is one of energy-conservation main path of hybrid vehicle.At present, in the parallel hybrid electric power system, when car brakeing was slowed down, driving engine and power drive system were linked together, the launched machine in-to-in of brake snub energy mechanical friction consumes, and can store the electric energy that utilizes again and can not be recovered as by motor.As shown in Figure 2, braking energy reclaims few, has therefore reduced the fuel efficiency of car load.
Summary of the invention:
The object of the present invention is to provide a kind of control method that the hybrid vehicle braking energy reclaims that improves, when car brakeing is slowed down, the utilization power-transfer clutch disconnects driving engine and power drive system, improve the electric power generation brake load simultaneously, the braking force that causes after throwing off with the compensation driving engine reduces, thereby has improved the percent recovery of braking energy.
Technical scheme of the present invention is achieved in that and improves the control method that the hybrid vehicle braking energy reclaims, be to be carrier with the entire car controller, by comprising entire car controller, motor and controller thereof, battery and administrative unit thereof, power-transfer clutch and controller thereof, acceleration pedal jaw opening sensor, brake pedal position sensor, the control system of compositions such as car speed sensor realizes; It is characterized in that when car brakeing is slowed down the utilization power-transfer clutch disconnects driving engine and power drive system, improves the electric power generation brake load simultaneously; When the information that entire car controller provides according to the acceleration pedal jaw opening sensor judges that acceleration pedal is in closed condition, instruction clutch controller combustion cutoff connects with power drive system, instructs electric machine controller to realize that electric power generation reclaims braking energy simultaneously; In whole braking procedure, entire car controller is constantly handled the hybrid power system work state information and is comprised the speed of a motor vehicle, vehicle acceleration, rate of braking requirement, battery electric quantity state etc., calculate in real time and send the motor braking torque demand to electric machine controller and instruct, institute's output power is stored in the electrokinetic cell, steadily stops until vehicle.
Good effect of the present invention is to have improved the percent recovery of braking energy under the prerequisite that guarantees identical deceleration and stopping performance, has also promptly improved the fuel efficiency of car load.
Description of drawings:
Fig. 1 is a parallel hybrid electric power system structural representation
Fig. 2 is the torque control method scheme drawing of present parallel hybrid electric power system during braking.
Fig. 3 is the torque control method scheme drawing of parallel hybrid electric power system during braking that the present invention proposes.
