The motor vehicle brake energy recycle control device is smooth in braking without mechanical noise and rapid in response without locking, realizes precise adjustment of braking force of each wheel according to actual conditions, improves stability of a vehicle body, can generate a large quantity of electric energy to provide auxiliary power, and realizes better mobility of the vehicle.
Description
Technical field:
The utility model relates to a kind of self-propelled vehicle, specifically a kind of self-propelled vehicle braking energy recovery control device.
Background technology:
At present, known motor vehicle brake device is to adopt the mode of friction to consume the vehicle movement energy, thereby reaches the purpose of deceleration.There is energy dissipation in existing deceleration way, problems such as brake facing wearing and tearing.It is overheated that particularly may there be brake plate in high capacity waggon when descending, thereby cause danger.Simultaneously because the intrinsic speed of response of mechanical braking is not suitable for the control of high-speed motion state.
Summary of the invention:
The purpose of this utility model provides a kind of self-propelled vehicle braking energy recovery control device.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of self-propelled vehicle braking energy recovery control device, it comprises by CAN bus and ECU electronic control unit bonded assembly MCU micro-control unit, be installed in the separately exited generator that drives by transmission system on the self-propelled vehicle wheel shaft, separately exited generator is connected with the MCU micro-control unit by the exciting current control module, and the electric energy that separately exited generator produces is sent into super capacitor through rectifying circuit, DC/DC control module and stored.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, braking is level and smooth, no mechanic sound, and reflection is rapidly, no locking, can accurately adjust each wheel braking force according to actual conditions, improve vehicle body stability, and can produce a large amount of electric energy, auxiliary power is provided, makes vehicle movement better.
Description of drawings:
Fig. 1 is a structural representation block diagram of the present utility model.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of self-propelled vehicle braking energy recovery control device, it comprises by CAN bus and ECU electronic control unit bonded assembly MCU micro-control unit, be installed in the separately exited generator that drives by transmission system on the self-propelled vehicle wheel shaft, separately exited generator is connected with the MCU micro-control unit by the exciting current control module, and the electric energy that separately exited generator produces is sent into super capacitor through rectifying circuit, DC/DC control module and stored.
The utility model MCU micro-control unit adopts ARM cortex-m0 treater, and in the present embodiment, this application-specific integrated circuit adopts the LPC1114 IC of NXP manufacturer production.This central controller is by CAN bus and the communication of ECU electronic control unit, accept ECU electronic control unit braking force intensity control,, provide different exciting currents by the inquiry internal database according to different B.P.s, exciting current is big more, and the braking force that can provide is also big more.Simultaneously, according to instruction, and the present speed of a motor vehicle, it is the super capacitor charging that aspect situation control DC/DC control modules such as electric capacity electric weight make it produce suitable charging current.
The utility model is when car retardation, the ECU electronic control unit passes through wheel speed sensors, rain sensor, acceleration pick-up, a large amount of vehicle body state sensor such as electronic gyroscope obtains the exact value of vehicle operating and road surface situation, step on the angle of brake according to chaufeur, calculate the braking force of each wheel by computing, provide exciting current by the MCU micro-control unit to separately exited generator, the electric energy that separately exited generator produces is sent into super capacitor through rectifying circuit, DC/DC control module and is stored.ECU electronic control unit controls separately exited generator generated output, promptly braking force when speed eases down to a certain degree, takes the mode of oppositely energising to allow self-propelled vehicle stop fully.
Because car retardation is based on the control system of electric signal, has the fast characteristics of speed of response with respect to mechanical braking sytem, the braking force of while each wheel of may command, science realizes brakig force distribution and ESP function.
The electric energy that super capacitor stores can according to different system architecture and vehicle conditions, or be the charging of automobile starting storage battery, or quicken for automobile starting is auxiliary according to present driving situation output auxiliary power, or is the automobile power cell charging.
