Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although this public affairs is shown in attached drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs
The scope opened completely is communicated to those skilled in the art.
Hybrid power system is the vehicle drive system for including two kinds of power sources of engine and motor, there is tandem, parallel connection
Three kinds of formula and series parallel type, heretofore described hybrid power system do not include series connection type hybrid power system.
Fig. 1 is the structure diagram of the control system of the embodiment of the present invention.As shown in Figure 1, control system includes vehicle control
It unit 10 processed, control unit of engine 20, motor control unit 30, battery control unit 40, gear box control unit 50 and passes
Sensor 60, the front end that sensor 60 is arranged on vehicle are used to measuring relative distance between vehicle and the front vehicles of vehicle and opposite
Speed, and full-vehicle control unit 10, control unit of engine 20, motor control unit 30, battery control unit 40, gearbox control
Unit 50 and sensor 60 processed are connected in parallel in CAN bus 100.
Wherein, control unit of engine 20, motor control unit 30, battery control unit 40, gear box control unit 50
Input signal include two parts, a portion is provided in the detection signal of the sensor in each related components, another
Part is the control signal that CAN bus 100 is sent to each control unit.The output signal of CAN bus 100 includes two parts,
A middle part is the control signal of related components executing agency, and another part is the correlation zero being sent in CAN bus 100
Part information, CAN bus 100 collect and vehicle other control units are sent to after the information of related components.
Further, sensor 60 is one or more of millimetre-wave radar, laser radar or camera.Sensor 60
For gathering the relative distance of this vehicle and front vehicles and relative velocity, and the form that the information collected is passed through CAN message
CAN bus 100 is sent to, after data processing, judges whether the relative distance of this vehicle and front vehicles and relative velocity are full
Sufficient engine start/stop demand.
Fig. 2 is the flow chart that engine starting is carried out using control method in the present invention.Fig. 3 is using being controlled in the present invention
Method carries out the flow chart of tail-off.As shown in the figure, when engine is closed, if the essential information of vehicle expires
Relative distance between the starting conditions of sufficient engine, vehicle and front vehicles is more than the first safe distance and vehicle and front vehicle
Relative velocity between is more than the first safe speed, then starts engine.If wherein there is any one condition to be unsatisfactory for starting
During the starting conditions of machine, then engine will not be started.Wherein, before this vehicle vehicle and the relative velocity of front vehicles are by being located at vehicle
The sensor acquisition of side obtains, and relative velocity is just, then front vehicles speed is more than this vehicle speed；Relative velocity be it is negative, then before
Square car speed is less than this vehicle speed.
Discounting for the relative distance and relative velocity between vehicle and front vehicles, meet in vehicle essential information and send out
Engine can start to work in the case of engine start condition, but traffic information determines next this vehicle needs to slow down, hair
It needs to stop quickly after engine start.Engine stop-stop-and-go during be operated in poorly efficient area, energy efficiency is low, influences whole
The economic performance of vehicle, and engine startup can cause to impact to vehicle, influence the comfort of vehicle.
When engine is in operating status, if the essential information of vehicle meets the stop condition of engine, vehicle with before
Relative distance between square vehicle is less than the second safe distance and the relative velocity between vehicle and front vehicles is less than the second peace
Full speed degree, then close engine.If wherein have the closedown condition that any one condition is unsatisfactory for engine, hair is not turned off
Motivation.
Discounting for the relative distance and relative velocity between vehicle and front vehicles, meet in vehicle essential information and send out
Engine can shut down in the case of motivation closedown condition, but traffic information determines next this vehicle needs to accelerate, hair
Motivation needs to re-start starting after closing.Engine stop-and-go-rise during be operated in poorly efficient area, energy efficiency is low, influence
Vehicle economic performance, and engine startup can cause to impact to vehicle, influence comfort.
Vehicle essential information includes engine information, motor information, battery information, gearbox information and whole vehicle information, vehicle
Belong to the external information of vehicle with the relative distance and relative velocity of front vehicles.
Wherein, engine information is detected by control unit of engine 20, including engine water temperature and engine speed.

Including clutch state and gear.Whole vehicle information is detected by full-vehicle control unit 10, including speed, throttle, brake and sky
Tune state.Full-vehicle control unit 10 completes the start-stop control function of engine, without additional control unit.
Further, the first safe distance in the present embodiment is 15m, and the first safe speed is 0m/s.Second safety away from
From for 40m, the second safe speed is 0m/s.I.e. when the engine of vehicle, which is in, closes, meet hair in the essential information of vehicle
In the case of the start-stop condition of motivation, if the relative distance of vehicle and front vehicles is more than 15m and relative velocity is more than 0m/s
In the case of, then start engine.When the engine of vehicle is in operation, meet the pass of engine in the essential information of vehicle
In the case of closing condition, if the relative distance of vehicle and front vehicles is less than in the case that 40m and relative velocity be less than 0m/s,
Then close engine.
By using the engine on-off control method and control system of hybrid electric vehicle of the present invention, by
The front of vehicle sets sensor, adds the relative distance between Ben Che and objects ahead vehicle and relative velocity is used as and starts
The basis for estimation of machine start-stop optimizes the start-stop number and operation interval of engine, reduces unnecessary engine start/stop mistake
Journey improves the economic benefit and comfort of vehicle.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
