then the DM 2021 under Don evolutionary exterior and interior, and whether to stop here? Of course the answer is no, according to past performance BYD “technology is king, innovation-oriented”, each out of a major facelift or facelift of new energy vehicles will be to enhance the core technology.
2,2021 section
Don DM electric drive technology functional integration:
2021, paragraph
Don DM and DM Tang architecture on a drive in the power of the same configuration, are from 2.0T engine BSG + + front motor start and stop the drive motor battery + + mid rear drive motors configured. However, paragraph 2021 Tang DM uses more advanced technology DM-p system, the maximum output power of the engine 2.0T 141 kilowatts, and the cylinder head, intake and exhaust turbo system adjusted for PHEV drive technology.
Photo section 2021 Tang DM cabin power state close-up details the various subsystems.
Green Arrow: 2.0T engine, BSG start and stop the motor, the drive motor before and after the high-temperature heat circulation line common pot fluid
yellow arrow: power battery thermal management fluid circulation line pot [123 ]
the red arrow: the IPB integrated braking system of the brake fluid infusion pot (ABS valve element integrated with the master cylinder)
blue arrow: “2 in 1” dual front motor control module (BSG start and stop the motor and motor pre-driver)
Note that, the front “2 in 1” motor control module 2021 in the first application of paragraph DM Tang, the start and stop the motor BSG original independent control module integrated into the pre-driver motor control module. Considering the BYD Qin \ Song \ Tang DM models configuredPre 110 kilowatts and the motor drive control module setting the independent state. It is foreseeable that, in the future, “2 in 1” Front dual motor control module will be three cars BYD DM engine four-wheel drive version of the standard configuration, and strengthen again in the integration. On a
Tang left section 2021 equipped DM “2 in 1” Pre dual motor control module
Tang right picture pre-driving motor control module DM assembly
in practice, the motor control module are two kinds of state of the art includes a DCDC converter functions, and the configuration of a DM Tang BSG start and stop the motor and motor control module, the space occupied is less than 2021, paragraph “2 in 1” Don front dual motor control module DM configuration and simplifies the number of heat pipes to enhance heat dissipation efficiency.
on the left is a Tang BSG start and stop the motor DM above configuration, the servo master cylinder vacuum valve
right picture 2021 after the paragraph Tang DM configuration IPB integrated braking system, the vacuum valve cancel “naked” start and stop the motor in a state BSG
2021, paragraph
Tang DM IPB mounted brake system consistent with DM Han, an ABS brake master cylinder body with integrated electrical and hydraulic integration, the biggest advantage is to improve the efficiency of energy recovery, the braking efficiency of the brake system upgrade again. Because the valve element removed in vacuo set individually, vehicle weight is reduced.
Although the two Tang DM are configured with the same 15,000 rev / min, the liquid-cooling BSG start and stop the motor, but Don paragraph 2021 DM adapted BSG start and stop the motor control module and the front drive motor control module for the integration, perhaps this physical change brings advantages, but also reflects the evolution of the charge-discharge efficiency and control strategies in terms of traffic.
3,2021, paragraph
Tang DM discharge control strategy evolution:
Tang on a DM can be completed in 4.5 seconds 0-100 km / h acceleration test, Tang DM 2021 shall only 4.3 seconds. The new DM-p technology, maximum output power of 141 kilowatts, optimized for PHEV technology2.0T engine contributed. But at the same time enhance the acceleration of the introduction of the new 2021 models DM Tang driving charge and idle charge control strategy, reflecting the strong core technology advantages of BYD reserves have again.
In ECO + HEV mode, the percentage of battery SOC75 state, the driving speed of 35 km / h (red arrow), paragraph 2021 Tang electrically driven state is still in the DM , does not start the engine (blue arrow engine speed is 0).
In ECO + HEV mode, battery status SOC45 percentage (yellow arrow), the driving speed of 49 km / h (green arrow), paragraph 2021 Tang DM is still in an electrically driven state, the engine does not start (red arrow engine speed is 0).
In ECO + HEV mode, battery status SOC44 percentage (yellow arrow), the driving speed of 53 km / h (green arrow), paragraph 2021 Tang DM into the hybrid engine is started and the drive state (red arrow engine speed is 900 rev / min).
In October 2018 – during the production of the DM Tang April 2019, the vehicle speed 30 km / h, ECO + HEV mode and start the engine power output. DM 2020 Tang discontinued enhance the speed of vehicles to 40 km / h, ECO + HEV mode and start the engine power output. Tang DM in paragraph 2021 ECO + HEV mode, again to enhance the speed of vehicles to 50 km / h, engine start and outputs the power.
In congested urban areas, the vehicle start, acceleration, parking conditions, often in the DCT semi-linked state, is easy to wear and increased temperature. Whether been on a Tang DM, or 2021 models Tang DM, through ECO + HEV mode, at low speed state, the engine will not start DCT also at a standstill, not only to reduce engine emissions and fuel consumption, but also helps to maintain the use of DCT life. But paragraph 2021
Tang drive speed of DMRaised to 50 km / h, before starting the engine control strategy, consumes more battery power for when congestion exchange for better feel and maximize Driving DCT life.
Since the vehicle speed is raised to start the engine 50 km / h, it is bound to consume more battery power loading, then charged with the driving control of the idle charge strategy will have the change.
ECO charged or SPORT + HEV mode, the battery SOC value is less than 15 percent (red arrow), whether running or stop, the engine will start to enter the lane or an idle state of charge, until the SOC restored to 25 percentage value. Forced charging state, the engine idle speed is 800 rev / min (yellow arrow), the idle charging power is limited to 2 kilowatts (green arrow).
In Tang P DM-blocking state, deep pressed the accelerator, BSG activation start and stop the motor, the first type into the idling power generation mode in which the charging power of 5 kilowatts .
Remarks: a first type Tang DM generating the idle mode charging power of 4 kW.
In Tang P DM-blocking state, the accelerator pedal tread depth in the end, start and stop the motor activation BSG, the second type into the idling power generation mode, and the charging power of 8 kilowatt.
Remarks: a second type of DM Tang idle mode charge generating power 8 kilowatts.
At present, development and manufacture of their own set of BYD 15,000 rev / min, the liquid-cooling BSG start and stop the motor is applied on the first Qin Pro DM, followed by the Song Pro DM, DM Han and Tang DM on 2021 models.
Pro Song DM dual wheel drive engine, on a DM Tang wheel drive and dual engine Han DM, because the pre-drive motor removed, to retain the generated power driving rear drive motors, BSG motor steady at 12-14 kW, so that the vehicle charge and discharge efficiency is almost in balance.
In 2021 Tang models DMOn, BSG motor start-stop control and the front end of the control terminal of the drive motor 110 kilowatts a “2 in 1” integrated, rear “3 in 1” maximum output power of the driving motor up to 180 kilowatts, the HEV mode and the engine speed access liter to 50 km / h. In order to maintain a balanced driving charge and discharge efficiency, Tang DM paragraph 2021 of BSG start and stop the motor driving the charging power is maintained at 14 kilowatts, Han DM comparable performance.
Note: DM Tang on a driving power of 12 kilowatts power generation
4,2021 section
Don DM driving comfort and smart driving:
in Tang DM + FSD IPB integrated braking system variable damping shock absorber of the support, and the amount of vehicle acceleration when the dynamic braking control becomes stronger, almost made to solve the fundamental move “nod” issue. Tang 2021 models exactly the same front and rear suspension on a Tang DM, aluminum material and the frame-type multi-link rear sub-frame exchange is better to set weight.
intelligent ecological health of the cockpit Tang DM, with super biochemical oxygen bar sterilization mode and intelligent function. Super biochemical model with HEPA CN95, PM2.5 green net air quality optimization system, negative ion generator, comprising particles of 0.3 μm the percentage of the 95 degree filtering capabilities.

Note: DM 2021 under Don DiPilot integrated intelligent driver assistance systems, including line and assist, lane keeping assist new features, reverse side of the car alarm, intelligent remote control mode, etc. security configuration.
I have something to say:
In the visual impact of the new 2021 models Tang DM look and new interior, with the blessing of many strategies to enhance and control the core technology, BYD has consistently adhered to continue projecting the “iterative technique “R & D strategy evolution. The new architecture and drive DM-p “e internet” in the system “3 in 1” combined electric drive assembly, and DM is still a continuation of BYD EV aspect intersect in the art. Optimize the integration of the cooling system and motor control system BSG, BYD thermal efficiency and improve the charging efficiency of specific performance.
of course, be read and judged by lifting the state of many technical Tang DM 2021 models, BYD core technology sales models adapted itself has a strong technological advantage and upgrade space, optimizing the efficiency of subsequent drive models and the lightweight vehicle, will show a stronger technical strength.
