Entire car controller 10 sends torque signal according to car load operating mode with from the demand of chaufeur.Engine controller 20 and electric machine controller 30, respectively according to the torque signal that entire car controller 10 sends, control the driveline torque of driving engine and motor realization expectation.
The moment of torsion processing module 101 of entire car controller 10 receives torque request signal by its torque request processing unit 1010, and processes received torque request signal, to calculate the total torque of power system desired output.This torque request signal can be the acceleration pedal signal that engine controller 20 sends over, exemplarily, this acceleration pedal signal can be transferred to entire car controller 10 by engine controller 20 by CAN, and outside the CAN communication verification of routine, this signal also can increase further checking signal, as Checksum verification, to guarantee the correctness of Signal transmissions.
The total torque of torque request processing unit 1010 required for the information calculating such as acceleration pedal, brake pedal, the speed of a motor vehicle, rotating speed, gear of entire car controller 10.Calculated total torque, based on the efficiency of driving engine and motor, to improve the whole efficiency of power system for target, is distributed to driving engine and motor by the torque distribution unit 1011 of entire car controller 10.Briefly, the total torque of power system desired output, according to hybrid dynamic system pattern, is reasonably distributed into the moment of torsion to the moment of torsion of driving engine and motor, and is transported out by distributed moment of torsion by torque distribution unit 1011.In this example, hybrid dynamic system pattern can comprise closedown (OFF), engine cold-start, traditional vehicle pattern, idling charge system, intelligent charge, motor power-assisted, regenerative braking isotype; Correspondingly, to different hybrid dynamic system patterns, adopt different torque distribution modes, so that the torque demand of chaufeur is distributed to driving engine and motor.According to an example of the present invention, based on the distribution of torque distribution unit 1011 pairs of moments of torsion, the engine torque signal distributing to the moment of torsion of driving engine in order to instruction is flowed to engine controller 20, the Motor torque signal distributing to the moment of torsion of motor in order to instruction is sent into moment of torsion arbitration unit 1012.It should be noted that, this example is only for schematically illustrating specific embodiment of the invention, and the engine torque signal at this point do not limited based on the moment of torsion distributing to driving engine directly must send to engine controller 20 by torque distribution unit 1011.
The moment of torsion arbitration unit 1012 of entire car controller 10 arbitrates Motor torque according to the operating mode such as automatic start-stop, regenerative braking, high-tension battery electric quantity balancing of vehicle, then Motor torque signal is sent to electric machine controller 30, to realize the torque demand to motor.In other words, because motor needs to realize the several functions such as driving, energy feedback, engine start/stop, so the moment of torsion distributing to motor must be arbitrated it by moment of torsion arbitration unit 1012, then generate corresponding Motor torque signal according to arbitration result, send to motor.Exemplarily, moment of torsion arbitration unit 1012 receives to the torque signal of motor from torque distribution unit 1011, and based on the hybrid dynamic system pattern of the vehicle above mentioned, select suitable Motor torque to generate Motor torque signal from multiple Motor torque respectively, then send it to electric machine controller 30.Briefly, the concrete calculating of Motor torque is different according to the difference of mixed dynamic model formula, the mode of such as distributing based on efficiency under intelligent charge pattern carrys out distribute torque, under motor assistant mode, provide positive driving torque to distribute based on motor, under regenerative braking pattern, provide negative driving torque to distribute based on motor.In practical application, partial function block in moment of torsion arbitration unit 1012, such as from multiple engine torque, select suitable moment of torsion to generate engine torque signal according to hybrid dynamic system pattern and send to the function of engine controller, also can be integrated in torque distribution unit.
Entire car controller 10 can be communicated by CAN with between engine controller 20 and electric machine controller 30.The signal of the information such as acceleration pedal, brake pedal, the speed of a motor vehicle, rotating speed, gear can be related at entire car controller 10 and the signal that transmits between engine controller 20 and electric machine controller 30.Otherwise engine controller 20 comprises accelerator pedal position signal, engine speed, the signals such as driving engine indication torque, engine friction torque, maximum engine torque, driving engine minimal torque by CAN to entire car controller 10 transmission; Electric machine controller 30 can send the signals such as motor speed, motor actual torque, motor temperature by CAN to entire car controller 10.In above-mentioned signal, accelerator pedal position signal, engine rotational speed signal and driving engine minimal torque by be used in as mentioned below to driving engine allow moment of torsion calculating in, accelerator pedal position signal, motor speed signal be then used in as mentioned below to motor allow moment of torsion calculating in; And other signal also will be used for the calculating to moment of torsion such as entire car controller moment of torsion processing module 101, engine controller moment of torsion processing unit 201 and electric machine controller moment of torsion processing unit 301 as required.It should be noted that, according to the present invention, based on there is fixing speed ratio relation between the driving engine connected by belt and motor, therefore engine speed and motor speed can be changed mutually, so in examples more of the present invention, substitute motor signal to calculate Motor torque with engine signal.
In entire car controller 10, car load torque safety module 103 is according to the rotating speed of current driving engine or motor, and acceleration pedal position signal, calculates the permission moment of torsion of driving engine and motor under current working respectively, and generates accordingly and allow torque signal.According to the embodiment of the present invention, by the permission moment of torsion of engine health unit 1031 according to driving engine under current engine speed and acceleration pedal position signal calculating current working, and driving engine permission torque signal is generated; By the permission moment of torsion of motor safety unit 1032 according to motor under current motor speed and acceleration pedal position signal calculating current working, and generate motor permission torque signal.This driving engine allows torque signal to send to engine controller 20, and this motor allows torque signal to send to electric machine controller 30.Preferably, the permission moment of torsion of the driving engine calculated and the permission moment of torsion of motor slightly larger than normal moment of torsion, that is all should can not affect normal functional layer moment of torsion.
Below to relate to the signal of accelerator pedal position, the system of Fig. 1 is described.Entire car controller 10 is after receiving acceleration pedal position signal, the driving engine requested torque (based on context allowing moment of torsion also referred to as driving engine) allowed under the position signal of the engine speed current according to vehicle and acceleration pedal calculates current working in car load torque safety module 103, the motor requested torque (based on context allowing moment of torsion also referred to as motor) allowed under calculating current working according to the position signal of motor speed and acceleration pedal, and allowed by the driving engine calculated moment of torsion and motor to allow moment of torsion to be sent to engine controller 20 and electric machine controller 30 respectively further.
Engine controller 20 is received from the engine torque signal that moment of torsion processing module 101 sends and the driving engine permission torque signal sent from driving engine safe unit 1031.Engine torque processing module 201 carries out driving filtering to received engine torque signal, and to avoid the rapid fluctuation of engine torque in the situations such as anxious step on the accelerator and anxious accelerator releasing, thus it is more steady that the moment of torsion of driving engine is exported.In engine torque limiting module 203, the engine torque signal through driving filtering is limited with driving engine permission torque signal, specifically, when the driving engine be less than involved by driving engine permission torque signal of the engine torque involved by engine torque signal allows moment of torsion, engine controller 20 controls driving engine with normal torque signal (that is engine torque signal), it is made to work with corresponding moment of torsion, and when the engine torque involved by engine torque signal is greater than the engine torque involved by driving engine permission torque signal, engine controller 20 driving engine allows torque signal as the torque signal controlling driving engine.According to the present embodiment, engine controller 20 also comprises parts processing module 206, and it receives the torque control signal that engine torque limiting module 203 exports, and according to this signal control associated components, such as, controls the throttle gate of vehicle, ignition angle and fuel charge.In addition, this parts processing module 206 also gathers the moment of torsion of the actual actual output of information calculation engine such as suction quantity, ignition angle.
Engine torque monitoring module 205 is received from the driving engine permission torque signal that engine health unit 1031 sends, and the permission moment of torsion involved by this permission torque signal and the actual moment of torsion produced of driving engine is compared.Described permission moment of torsion is greater than at driving engine actual torque, and when the difference of driving engine actual torque and this permission moment of torsion reaches the first predetermined value, engine controller 20 sends breakdown signal, makes related function module or equipment to carry out fault handling, also can remind operating personal; When the difference of preferred engine actual torque and this moment of torsion reaches the first predetermined value, engine controller 20 sends breakdown signal, and transmission makes engine torque reduce to the control signal of 0 to driving engine.In practical application, this first predetermined value with make actual torque when being greater than this permission moment of torsion also can support vehicles safely, it can be different because of particular case.When engine controller 20 produces torque monitoring fault, engine controller 20 is interrupted with the communication of entire car controller 10, automobile is made to enter limping pattern, that is, entire car controller 10 does not respond acceleration pedal request, driving engine maintains high idle speed and rotates, and hybrid electric motor operates in generator mode.
As described herein, according to the present invention, entire car controller 10 generates torque signal, and the actual torque of engine torque monitoring module 205 pairs of driving engines of engine controller 20 is monitored, not only clear in structure, and when there is communication failure between entire car controller 10 and engine controller 20, still can realize the monitoring to actual torque.
The Motor torque signal that electric machine controller 30 sends from moment of torsion processing module 101 and allow torque signal from the motor that motor safety unit 103 sends.Motor torque processing module 301 carries out driving filtering to received Motor torque signal, more steady to make the moment of torsion of motor export; It should be noted that, when automobile is mild hybrid power system, the impact of motor on driving performance is less, can cancel driving filtering, in this case, the Motor torque signal that moment of torsion processing module 101 sends is sent to the Motor torque limiting module 303 of electric machine controller 30.In Motor torque limiting module 303, the motor received is utilized to allow torque signal to carry out limiting motor torque signal.Specifically, when the Motor torque involved by Motor torque signal is less than the Motor torque involved by motor permission torque signal, electric machine controller 30 controls Motor torque with normal torque signal, and when the Motor torque involved by Motor torque signal is greater than the Motor torque involved by motor permission torque signal, electric machine controller 20 motor allows torque signal as the torque signal controlling motor.To control motor inverter through the Motor torque signal of restriction process.Motor torque monitoring module 305 gathers the signals such as the rotating speed of motor, electric current and bus voltage, calculates the actual output torque of motor.Torque monitoring module 305 compares motor actual torque further and motor allows moment of torsion, and when actual torque is greater than motor permission moment of torsion and actual torque and motor allow the difference of moment of torsion to reach the second predetermined value, produce torque monitoring breakdown signal, make related function module or equipment to carry out fault handling, also can remind operating personal.If electric machine controller 30 produces torque monitoring breakdown signal, then entire car controller 10 reduces to 0 the moment of torsion sent to involved by the torque signal of electric machine controller 30, interrupt the communication with electric machine controller simultaneously, disable motor inverter, and engine controller 20 normally works, that is car load can respond acceleration pedal request.In practical application, this second predetermined value with make actual torque be greater than motor allow moment of torsion time also can support vehicles safely, it can be different because of particular case.Electric machine controller also comprises parts processing module 306, and it receives motor control signal from described Motor torque limiting module 303, to control voltage, the electric current and rotating speed etc. of motor.As described herein, according to the present invention, entire car controller 10 generates torque signal, and the actual torque of Motor torque monitoring module 205 pairs of motors of electric machine controller 30 is monitored, not only clear in structure, and when there is communication failure between entire car controller 10 and electric machine controller 30, still can realize the monitoring to motor actual torque.
According to embodiments of the invention, the torque monitoring system of hybrid vehicle can also comprise correction verification module 40.Correction verification module 40 can be implemented the first module, the second module, and the 3rd module.Memory unit (not shown) etc. in first module independent detection entire car controller, and when memory unit breaks down, entire car controller is restarted; Second module detects the memory unit (not shown) etc. in electric machine controller, and when memory unit breaks down, electric machine controller is restarted; 3rd module then passes through the catechetical verification between entire car controller and electric machine controller, to check the part or parts that relate to calculating in entire car controller and electric machine controller.
In sum, these, when driving engine or motor occur that moment of torsion surprisingly increases, surprisingly can increase and detect and carry out suitable fault handling by torque monitoring system according to the present invention, ensure the torque safety of car load, and then ensure the safety of vehicle and chaufeur.And according to the present invention, entire car controller is cooperatively interacted by its moment of torsion processing module 101 and torque safety module 103, output torque signal.Engine controller and electric machine controller then realize the moment of torsion of driving engine and motor respectively according to received torque signal, and monitor the actual torque of driving engine and motor respectively.As can be seen here, the torque monitoring system of hybrid vehicle of the present invention, separately torque monitoring is carried out to its institute's driving engine that controls and motor by engine controller and electric machine controller, not only clear in structure, and it also avoid in prior art the following problem that may occur: because the actual torque of entire car controller to motor and driving engine is monitored, when causing occurring communication failure between entire car controller and electric machine controller or engine controller, just cannot communicate with electric machine controller or engine controller, thus cannot monitor the driver stage of electric machine controller or engine controller.
In all examples of the present invention, what term " motor " referred to is mixed dynamic motor.Term " mixed dynamic motor " refers to the motor for hybrid vehicle, generally speaking, it provides energy by high-tension battery, and this mixed dynamic motor can provide driving torque, also can be used for generating, to realize the hybrid power functions such as the automatic start-stop function of such as driving engine, intelligent charging function, motor assist function, motor feedback function.In addition, entire car controller, electric machine controller and engine control can realize respectively in the form of hardware, and also can realize in suitable hardware by software mode, such as dsp processor etc., only need it can reach function of the present invention.
Fig. 2 is exemplary power system structural representation of the present invention.This figure simply illustrates the relation between the monitored control system of above-described mixing dynamical vehicle torsional moment and automobile dynamic system.As shown in the figure, motor 4 is connected by belt with driving engine 1, and the power that motor and/or driving engine produce inputs to wheel by change speed gear box 2 and main reduction gear 3.Motor 4 is connected with motor inverter 5, and should both be powered by battery 6.According to the present invention, as shown in Figure 2, motor 4 and motor inverter 5, and be connected respectively by high-tension line (HV:high voltage) between motor inverter 5 with battery 6.Motor inverter 5 is controlled by electric machine controller 30, and battery 6 is controlled by battery management system 11.1, driving engine is controlled by engine controller 20.Change speed gear box 2 is controlled by gearbox control 8.Illustratively, entire car controller 10 is connected by CAN 60 with engine controller 20, gearbox control 8, electric machine controller 30 and battery management system 11.Entire car controller 10 receives vehicle-state by CAN 60 from each controller, and sends torque signal to engine controller 20 and electric machine controller 30.
Driving demand, according to incoming signals such as accelerator pedal position, brake pedal position, gearshift position, is finally converted into the torque request to driving engine 1 and mixed dynamic motor 4 by entire car controller 10.When driving engine 1 idling, BSG motor (Belt-driven StartedGenerator starts power generation integrated motor) generating, maintains car load low pressure coulomb balance; When medium and small throttle request, driving engine 1 provides main driving torque, BSG motor for regulating engine working point, increase system efficiency; When large throttle acceleration request, driving engine 1 and BSG motor all provide driving torque; When unclamping throttle, engine stop fuel feeding, BSG motor reclaims car load kinetic energy and charges to high-tension battery.
As above property exemplified by 1 and 2 by reference to the accompanying drawings explanatorily, by torque monitoring system of the present invention, can be monitored moment of torsion effectively, thus ensure that the safety that moment of torsion exports.
