Fig. 1 is the torque monitoring exemplary system structural representation of hybrid vehicle described in the utility model.As shown in the figure, described system 1 comprises entire car controller 10, engine controller 20 and electric machine controller 30.Entire car controller 10 comprises car load moment of torsion processing module 101, moment of torsion security module and torque monitoring module; Wherein, the moment of torsion security module comprises engine health unit 1031 and motor safety unit 1032, and the torque monitoring module comprises engine torque monitoring unit 1051 and Motor torque monitoring unit 1052.Engine controller 20 comprises engine torque processing module 201 and engine torque limiting module 203.Electric machine controller 30 comprises Motor torque limiting module 303, alternatively, can comprise Motor torque processing module 301.Here need to prove that car load moment of torsion processing module 101, engine torque processing module 201, engine parts processing module 206, Motor torque processing module 301 (if any) and the motor component processing module 306 that hereinafter will mention in describing can be generically and collectively referred to as functional layer; The moment of torsion security module also can be described as safe floor; Engine torque limiting module 203 and Motor torque limiting module 303 can be generically and collectively referred to as limiting layer; And the torque monitoring module can be generically and collectively referred to as supervisory layers.
Entire car controller 10 calculates the car load moment of torsion according to the demand of car load operating mode and chaufeur and sends torque signal at driving engine and motor.30 engine torque signal and car load torque signals that send according to entire car controller 10 respectively of engine controller 20 and electric machine controller, control driving engine and motor are realized desired driving system moment of torsion.
The moment of torsion processing module 101 of entire car controller 10 receives the torque request signal by its torque request processing unit 1010, and the torque request signal that is received is handled, to calculate the total torque of power system desired output.This torque request signal for example can be the acceleration pedal signal that engine controller 20 sends over, as example, this acceleration pedal signal can be given entire car controller 10 by the CAN bus transfer by engine controller 20, and outside the CAN of routine communication verification, this signal also can increase further checking signal, as the Checksum verification, to guarantee the correctness of signal transmission.
The torque request processing unit 1010 of entire car controller 10 is according to needed total torques of information calculations such as acceleration pedal, brake pedal, the speed of a motor vehicle, rotating speed, gears.The torque distribution unit 1011 of entire car controller 10 is target based on driving engine and efficiency of motor with the whole efficiency that improves power system, and the total torque that is calculated is distributed to driving engine and motor.Briefly, torque distribution unit 1011 is reasonably distributed to driving engine and motor according to the hybrid dynamic system pattern with the total torque of power system desired output.In this example, the hybrid dynamic system pattern can comprise and closes (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 utility model, distribution based on the 1011 pairs of moments of torsion in torque distribution unit, the engine torque signal that will comprise the moment of torsion of distributing to driving engine flows to engine controller 20, and the Motor torque signal that will comprise the moment of torsion of distributing to motor is sent into moment of torsion arbitration unit 1012.Need to prove that this example only is used for schematically illustrating concrete enforcement of the present utility model, the engine torque signal that does not at this point limit based on the moment of torsion of distributing to driving engine must directly send to engine controller 20 by torque distribution unit 1011.
The moment of torsion arbitration unit 1012 of entire car controller 10 is arbitrated Motor torque according to operating modes such as the automatic start-stop of vehicle, regenerative braking, high-tension battery electric quantity balancings, then the Motor torque signal is sent to electric machine controller 30, to realize the torque demand of motor.In other words, because motor need be realized multiple functions such as driving, energy feedback, engine start/stop, must arbitrate it by moment of torsion arbitration unit 1012 so distribute to the moment of torsion of motor, generate corresponding Motor torque signal according to arbitration result then, send to electric machine controller 30.As example, moment of torsion arbitration unit 1012 is 1011 torque signals that receive to motor from the torque distribution unit, and based on the hybrid dynamic system pattern of the vehicle of above mentioning, select suitable Motor torque to generate the Motor torque signal from a plurality of Motor torques respectively, again this Motor torque signal is sent to electric machine controller 30.Briefly, the concrete calculating of Motor torque is different because of the difference of mixing the dynamic model formula, for example the mode of distributing based on efficient under the intelligent charge pattern is come distribute torque, under the motor assistant mode, provide positive driving torque to distribute, under the regenerative braking pattern, provide negative driving torque to distribute etc. based on motor based on motor.In the practical application, partial function piece in the moment of torsion arbitration unit 1012, such as from a plurality of engine torques, selecting suitable moment of torsion to generate engine torque signal according to the hybrid dynamic system pattern and sending to the function of engine controller, also can be integrated in the torque distribution unit.
