Basic structure due to hybrid vehicle knows by those skilled in the art and knows, therefore this is no longer going to repeat them.
The control method of distributing according to the hybrid electric vehicle power of the embodiment of the present invention is described below with reference to Fig. 1 and Fig. 2.
As depicted in figs. 1 and 2, specifically, the control method of distributing according to the hybrid electric vehicle power of the embodiment of the present invention comprises the following steps:
First, battery charge state (SOC) and demand torque (Trqst) parameter (representing with curve 1 and curve 2 respectively in Fig. 2) of hybrid vehicle is detected.Wherein car load general controller according to acceleration pedal information, can adopt the mode of tabling look-up to carry out moment of torsion and resolves mensuration demand torque parameter value.
Then, the car load general controller (HCU) of hybrid vehicle is passed through in electric-only mode (EV), the power distribution mode switching hybrid vehicle between hybrid mode (HEV) and pure engine mode according to the battery charge state measured and demand torque parameter.
Hybrid mode comprises motor transitional to engine mode and motor assist pattern, and in motor assist pattern, the driving engine of hybrid vehicle is as main power and the motor of hybrid vehicle gets involved Power output as auxiliary power source.Rotor inertia due to motor is far smaller than the rotor inertia of driving engine, and therefore motor is got involved Power output frequently and also can not be caused impact to vehicle.
Thus, the control method that hybrid electric vehicle power according to the present invention distributes is by motor assist pattern, control driving engine as main power and motor as auxiliary power source, therefore, it is possible to effectively weaken due to auxiliary power source frequently get involved Power output and to vehicle produce impact, optimize the driver comfort of hybrid vehicle, adopt driving engine as main power and motor can keep the dynamic property of vehicle can reach again the object of energy-saving and emission-reduction as the mode of auxiliary power source simultaneously.In addition, the control method of hybrid electric vehicle power distribution of the present invention is simply effective.
In fig. 2, horizontal axis plots time axle, and be divided into six stages to represent six different dynamic allocation models of hybrid vehicle respectively.The size of longitudinal axis representation parameter numerical value.The parameter of hybrid vehicle adopts different curves to represent respectively: curve 1 represents battery state of charge, and curve 2 represents demand torque, and curve 3 represents motor output torque (T
m), curve 4 represents engine output torque (T
e), curve 5 represents brake pedal, and curve 6 represents acceleration pedal.
As shown in Figure 1, according to some embodiments of the present invention, detect the battery charge state of hybrid vehicle and demand torque parameter value, and respectively with predetermined battery SOC (SOC
set) and the max. output torque (T of motor
mmax) compare, when battery charge state is greater than predetermined battery SOC and demand torque is less than the max. output torque value of motor, power-control method of the present invention controls hybrid vehicle and is switched to electric-only mode.Predetermined battery SOC is one and is greater than battery charge state minimum value (SOC
min) preset value, and can to make the appropriate adjustments with the design parameter of hybrid vehicle as required.
As shown in Figure 2, corresponding with above-mentioned electric-only mode, at t
0before moment, battery charge state is higher, and demand torque is not very large, output torque (the torque responsive speed of motor is very fast) the rapid response to customer's need moment of torsion of motor, and therefore control method of the present invention controls hybrid vehicle and adopts electric-only mode outputting power.In the electric-only mode of embodiments of the invention, Motor torque almost overlaps with demand torque.In electric-only mode, engine torque (T
e) do not participate in Power output, therefore go to zero always, namely overlap with time shaft.
As shown in Figure 1, detect battery charge state and the demand torque parameter value of hybrid vehicle, and battery charge state is compared with predetermined battery SOC and battery charge state minimum value, the max. output torque of demand torque and motor is compared, be less than predetermined battery SOC when battery charge state and be greater than battery charge state minimum value, or when when battery charge state is greater than predetermined battery SOC, demand torque is greater than the max. output torque of motor, power-control method of the present invention controls hybrid vehicle and is switched to motor transitional to engine mode.At motor transitional in engine mode, the output torque of driving engine rises until the output torque of driving engine equals demand torque, and the output torque of motor declines until be zero simultaneously, and namely driving engine is taken over motor and carried out Power output.Wherein when battery state of charge reaches battery charge state minimum value, battery is forced to stop electric discharge to protect battery.
Preferably, at motor transitional in engine mode, motor output torque predetermined hold-time Duan Houzai starts to decline, and during to ensure that the output torque of driving engine is in low value, the Power output of hybrid vehicle can not interrupt.
As shown in Figure 2, corresponding to engine mode with motor transitional, at t
0to t
1in time period, the output torque predetermined amount of time of motor remains unchanged (as shown in FIG., at t
0certain hour section inner curve 3 afterwards remains unchanged, then declines suddenly), to guarantee that the synthesis output torque of driving engine and motor reaches demand torque.By this control policy, the Power output moment of torsion of vehicle does not interrupt, and keeps the acceleration sensation of vehicle.Subsequently, the output torque of motor starts to decline, and the output torque of driving engine rises, at t
1moment completes by the switching of electric-only mode to hybrid mode.After this process completes, the propulsion source of vehicle changes driving engine into by motor, and hybrid vehicle is driven as power by driving engine.
As shown in Figure 1, after motor transitional completes to engine mode, when demand torque is less than or equal to the max. output torque of motor (output torque of driving engine can satisfy the demands moment of torsion separately), controls automobile and be switched to pure engine mode.
As shown in Figure 2, corresponding with pure engine mode, at t
1to t
2in time period, demand torque remains unchanged, and driving engine is as only propulsion source, and motor does not provide Power output (curve 3 goes to zero and overlaps with time shaft).Now start output machine moment of torsion to equal demand torque, engine operation is at high-efficiency point.
As shown in Figure 1, detect the battery charge state of hybrid vehicle and demand torque parameter value, and respectively with the max. output torque (T of battery charge state minimum value and driving engine
emax) compare, when demand torque is greater than the max. output torque of driving engine and battery charge state is greater than battery charge state minimum value, power-control method of the present invention controls hybrid vehicle and is switched to motor assist pattern, and the max. output torque that demand torque equals driving engine adds the output torque of electrical generator.
As shown in Figure 2, corresponding with motor assist pattern, at t
2to t
3in time period, demand torque continues to increase and exceedes the max. output torque of driving engine.From t
2in the moment, motor gets involved Power output as auxiliary power source.Because the rotor inertia of electric machine rotation inertia opposite engine is much smaller, so the intervention of motor can weaken greatly to the impact of vehicle, transition can be very smooth-going.
As shown in Figure 1, when battery state of charge equals battery charge state minimum value, power-control method control hybrid vehicle of the present invention is switched to protection battery mode and no longer discharges to make battery.
As shown in Figure 2, corresponding with protection battery mode, at t
3to t
4in time period, battery charge state has reached battery charge state minimum value, and power-control method of the present invention does not allow battery pack to discharge again, so motor does not provide moment of torsion (at t
3to t
4time period inner curve 3 overlaps with time shaft substantially).From t
3moment rises, and motor starts to depart from, and because the rotor inertia of electric machine rotation inertia opposite engine is much smaller, can greatly weaken so motor departs from the impact of vehicle, transition also can be very smooth-going.Now, even if engine torque arrives maxim, but still can not reach demand torque, the battery pack of hybrid vehicle is also no longer discharged and is in wait charge condition.
As shown in Figure 1, when the brake pedal stepping on hybrid vehicle makes car retardation even stop, the energy now produced by the recyclable braking of the parts such as bearing shell is with to batteries charging.
As shown in Figure 2, brake corresponding with hybrid vehicle, at t
4to t
5in time period, brake pedal is stepped on (curve 5 rises and keeps level), vehicle carries out Brake energy recovery, now, curve 1 and curve 4 go to zero, now curve 3 is negative value (being positioned at below time shaft), and namely represent motor reversal, curve 1 rises (namely to batteries charging).
In addition, curve 2 is omnidistance to be changed with curve 6 is substantially corresponding, and namely demand torque changes with the change of acceleration pedal.
