Detailed description of the invention
Fig. 1 is the structural schematic diagram on pure electric vehicle learner-driven vehicle provided in an embodiment of the present invention；
Fig. 2 is the flow chart of pure electric vehicle learner-driven vehicle provided in an embodiment of the present invention control method.
Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
Fig. 1 is that the structural schematic diagram on pure electric vehicle learner-driven vehicle provided in an embodiment of the present invention is only illustrated in for ease of description
The relevant part of the present invention.
Pure electric vehicle learner-driven vehicle includes:
Vehicle control system (VCU), battery management system (BMS), power battery, motor control module (MCU), motor,
Five grades of manual transmissions, clutch, pedestrian's system for prompting (PPD) and the gas pedal of vehicle, brake pedal, clutch are stepped on
Plate, gearshift etc., acquisition power battery state, motor control module (MCU) acquire battery management system (BMS) in real time in real time
Motor status, motor output shaft are connected by clutch with five speed transmission, and vehicle control system (VCU) acquires electricity by CAN
A main the zero of the electronic control unit such as pond management system (BMS), motor control module (MCU), anti-blocking brake system (ABS) feedback
The state of component, while passing through the state of the components such as rigid line acquisition gas pedal, clutch pedal, gearshift, brake pedal.
In order to judge the state of clutch, clutch pedal is equipped with top switch, closes the switch when pedal is not operated,
It switchs and disconnects when stepping on, signal gives vehicle control system (VCU) by hard-wire transfer；In order to judge gear state, manual five grades
Speed changer gives vehicle control system (VCU) by hard-wire transfer, reverses gear when being linked into equipped with reverse gear switch and neutral position switch, signal
When, it reversing gear and closes the switch, vehicle is in reversing gear (R grades) at this time for VCU judgement, and when handle of gear rests on neutral gear, neutral position switch is closed,
Vehicle is in neutral gear (N grades) at this time for VCU judgement, if be linked into 1-5 grades, reverse gear switch and neutral position switch all disconnects, at this point, VCU
Judge that vehicle is in forward gear (D grades), without in 1-5 each gear installation switches.
Fig. 2 is the control method flow chart of electronic practice provided in an embodiment of the present invention, the electric instruction car control method
It is specific as follows:
The idling of electric instruction car simulation fuel vehicle is controlled, starts and stops working.
In embodiments of the present invention, idle speed control is specific as follows:
When input ignition signal, and when gear be in neutral position state, controls electric car and enter idling mode；
Under the idling mode under neutral position state, start motor, motor is controlled by PI control algolithm and is turned with setting idling
Speed operating；Under the idling mode under the state of reversing gear, start motor, motor is controlled with DES IDLE RPM by PI control algolithm
Operating；Through experiment test it is found that DES IDLE RPM is 800rpm when neutral gear and forward gear, when reversing gear due to one grade of transmission ratio with
Back gear ratio differs greatly, and in order to guarantee that front and back idling speed is consistent, idling is set as 480rpm；
In embodiments of the present invention, starting control method is specific as follows:
Under READY state, if gas pedal is operated, i.e., the stroke of gas pedal is more than 5%, then exits idling mould
Formula, into driving mode；
Under driving mode, the revolving speed of the torque request control motor based on gas pedal.
Under READY state, if gas pedal is not operated, still in idling mode, motor keeps DES IDLE RPM
(800rpm) operating.
Condition into READY state is:
Under the idling mode under neutral position state, motor speed reaches the first setting speed；
Through measuring, the first setting speed is that 600rpm is best.
Under the idling mode under neutral position state, if the first setting speed is not achieved in motor speed, motor stopping is controlled
Rotation；
In embodiments of the present invention, control method of stopping working is specific as follows:
When the idling mode under driving mode or READY state, let slip the clutch simultaneously hangs shelves, in loose clutch
During motor speed can be declined, if the gear hung is forward gear, when motor speed is brought down below the first rotary speed threshold value,
READY state is then exited, motor stalls are controlled, if the gear hung is to reverse gear, when motor speed is brought down below the second revolving speed
Threshold value then exits READY state, controls motor stalls, and need to make the return trip empty gear again, keyed ignition starting；Through measuring,
One rotary speed threshold value is 250rpm, and the second rotary speed threshold value is that 80rpm is best.
In embodiments of the present invention, the sound that pedestrian's reminding module (PPD) of vehicle exports is changed to the clear height recorded
The fuel vehicle engine sound of fidelity, PPD by CAN network and each controller communication, the enable signal of real-time reception VCU and
The motor speed signal that MCU is issued, VCU starts to control PPD broadcasting engine sound after vehicle igniting, and PPD control gives great volume
It is small directly proportional to motor speed, make the function of electric instruction car as far as possible close to fuel oil learner-driven vehicle in this way.
It the starting of electric instruction car control method provided by the invention control electric instruction car simulation fuel vehicle, idling and puts out
Fire, and in order to improve the validity of simulation, it is controlled using forward-reverse double idle, and in the base of electric vehicle pedestrian's prompting function
The function of simulation fuel engines sound is upgraded on plinth.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
