Abstract
The open a kind of Start system for vehicle engine of the present invention, including motor, for the controller controlling described motor and the powertrain control module being connected with described controller, wherein, described motor is connected with the water pump of electromotor and engine-cooling system, and described controller is configured to control described selection of Motor and starts electromotor or drive water pump.The starting system of the present invention, starts motor and is used as the driving motor of water pump after engine start is completed, eliminate a motor, thus can save space and reduce cost.
Description
Technical field
The present invention relates to a kind of Start system for vehicle engine.
Background technology
Along with the deterioration of earth environment, environmental problem have become as people must faced by vital conjuncture, joint
Can reduce discharging and become the unalterable quota of most industries.For complying with the development trend of energy-saving and emission-reduction, automobile vendor exists
Devoting Major Efforts To Developing and popularization start shutdown system, in parking, described starting shutdown system treats that row state is (as red
Stop when stopping before lamp or run into traffic jam) under, temporary close electromotor, thus fuel-efficient and reduce tail
Gas discharges, and when being converted into enforcement state, resets electromotor.
Existing vehicle motor starts shutdown system, the function singleness of each motor, rises as started motor
No longer working after having moved electromotor, motor utilization rate is low, and cost is high.
It is desirable to provide a kind of novel Start system for vehicle engine.
Summary of the invention
The embodiment of the present invention provides a kind of vehicle motor to start shutdown system, including motor, for controlling
The controller of described motor, wherein, the water pump phase of described motor and electromotor and engine-cooling system
Even, described controller controls described selection of Motor and starts electromotor or driving water pump.
Preferably, described motor is DC brushless motor.
Preferably, described motor is internal rotor permanent magnet motor.
Preferably, described controller and a rechargeable battery are connected.
Preferably, described motor is connected with electromotor by a reduction gear box.
Preferably, it is provided with clutch between described motor and water pump and between motor and reduction gear box.
Preferably, described vehicle motor starts the power that shutdown system also includes being connected with described controller
Assembly control module.
The vehicle motor of the present invention starts shutdown system, starts motor and is used as after engine start is completed
The driving motor of water pump, eliminates a motor, thus can save space and reduce cost.
In order to be able to be further understood that inventive feature and technology contents, refer to below in connection with this
Bright detailed description and accompanying drawing, but institute's accompanying drawing only provides reference and explanation use, is not used for the present invention
It is any limitation as.
Accompanying drawing explanation
Fig. 1 show the rough schematic view of the vehicle motor starting shutdown system of one embodiment of the invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by the detailed description of the invention of the present invention is described in detail, will make the present invention's
Technical scheme and other beneficial effects are apparent.
Fig. 1 show the rough schematic view of the Start system for vehicle engine of one embodiment of the invention.
Referring to Fig. 1, described vehicle motor starts shutdown system and includes motor, for controlling described motor
Controller and powertrain control module (the Power Train Control that is connected with controller
Module), wherein, described motor is connected with the water pump of electromotor and engine-cooling system, described control
Device processed is configured to control described selection of Motor and starts electromotor or drive water pump.
Wherein, described motor is DC brushless motor, DC brushless motor have starting current little, use
The advantages such as life-span length, no-spark are disturbed, noise is little.
It is to be appreciated that described motor can also is that internal rotor permanent magnet motor or brush motor.
Wherein, described controller and a rechargeable battery are connected.
Wherein, described motor is connected to electromotor by a reduction gear box.
Wherein, it is respectively provided with clutch between described motor and water pump and between motor and reduction gear box.
When electromotor starts, the clutch between described motor and water pump disconnects described motor and water pump,
Described controller controls described motor and starts electromotor by reduction gear box.After electromotor has started,
Clutch between described motor and reduction gear box disconnects motor and reduction gear box, described controller control
Make described motor and drive pump working.
The starting system of the present invention, starts motor and is used as the driving electricity of water pump after engine start is completed
Machine, eliminates a motor, thus can save space and reduce cost.
It is to be appreciated that the Start system for vehicle engine of the present invention can be used as vehicle motor starts parking
System.Described powertrain control module is connected with some sensors, described sensor and brake pedal or
Accelerator pedal (not shown) is connected, for detecting brake pedal or the state of accelerator pedal total to power
Control module is become to send corresponding signal.
Below the work process of the starting-parking of electromotor is described in detail.
When vehicle from running state conversion to parking when row state (such as running into red light), brake pedal quilt
Stepping on, now sensor sends stop sign to powertrain control module, by Powertrain control mould
Block electromotor is closed, and electromotor is temporarily closed therebetween, drives the motor of water pump can temporarily cease work
Make, it is also possible to do not quit work.When vehicle switches to enforcement state from parking until row state, braking is stepped on
Plate is released/and accelerator pedal is operated, and now sensor sends to powertrain control module and starts signal,
The powertrain control module corresponding signal of transmission is to controller, and this controller controls described electric motor starting and sends out
Motivation.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of invention and principle, should be included in this
Within the protection domain of invention.
