BYD was enlarged again.
A few days ago, BYD and Bosch jointly developed DTCs officially released, and will be taken into the Han EV four-wheel drive model.
What is DTCS
DTCS is the abbreviation of the Distributed TCS, that is, a distributed traction control system, which is specifically for new energy The driving force control system created by the car is used to ensure the best adhesion in various complex roads such as ice, snow, thereby achieving the tires basically not slippery.
The increase in DTCS function does not require additional hardware input, so the official decision will be upgraded by free OTA soon, EV four-wheel drive version of the user opens this feature. According to relevant engineers, DTCs can be applied to models in different driving forms such as pre-drive, back drive, four-drive, so that follow-up will gradually become the Han EV two-drive version and other models open this function. 
Thanks to the no additional hardware just mentioned, the characteristics of OTA open, DTCS “After loading”, BYD will continue to optimize it, thus continuous improvement of its functional performance.
What is the advantage of DTCs
For ease of understanding, we will first simply review the TCS.
TCS is the abbreviation of TRACTION Control System, ie the traction control system, which helps the vehicle to obtain optimum traction as much as possible under various conditions. 
The conventional TCS system is developed under the power architecture of the fuel vehicle, so early electric vehicles can only extend this technology, but There are certain limitations: compared to internal combustion engines, the driving unit of electric vehicles has a high torque response and high peak high, and therefore the electric vehicle is easier to break through the road attachment limit, and then the wheel slip causes the body instability. .
in order toEliminating this phenomenon, DTCs come to life, compared to traditional TCS, DTCS’s largest advantage is 10 times more response speed.
How does the DTCS increase the response speed 10 times?
By comparing the working path of DTCS and TCS in the figure, DTCs can be integrated into the motor controller after the DTCs can be seen. The step of the traditional TCS in the traditional TCS (Entry Motor Controller) is omitted, thereby shortening the working path and ultimately falling the entire torque response to 10 milliseconds from 100 milliseconds, and the speed is 10 times.
What is the advantage of the car with DTCS compared to the car that is not equipped?
We used the Han EV four-wheel drive version equipped with DTCs as an example, and the other variables were the same, only the different conditions of the traction control system, in the Bosch East China Sea The test site conducts a slippery pavement and the open pavement (i.e., a side wheel in a low adhesive road side wheel at a low adhesion road).
He mentioned above, DTCs have a shorter response time, which means that the system can make faster regulation when tire slippage. Maximize the sliding amount of the wheel.
In the instant, DTCS can be more quickly controlled by the slippery road, and DTCs can control the slippery slip when the tire is started, helping the vehicle to obtain as much adhesion as possible, and the reaction is equipped with DTCS. The vehicle accelerates faster. 
When driving on the open pave, suddenly stepping on the accelerator pedal, DTCs is more delicate to the vehicle, and the vehicle will only produce slight swing. The vehicle equipped with traditional TCS is facing similar situations, although there is no vehicle out of control, but the process of the entire control will be rough, and the swing of the body will be more obvious.
According to the official provided data, the Han EV four-wheel drive version of DTCs is accommodated in the snow surface 0-60 km / hour, the whole force is reduced by about 0.8 seconds, the ice surface is 0-50 km / hour, and the speed is reduced by about 2 seconds, and the highest controllable fiber of the ice and snow is increased by about 5-10 km / hour.
State Review
The growing electric vehicle seems to have different drive systems and fuel cars, and the rest seem to be completely moved. Come,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, A vivid example, since the choice of electric vehicles, it is necessary to do the electric car. In order to adapt the motor output characteristics, the DTCs created is just a beginning. In the future, there will be more technologies for electric vehicles, which is born for electric vehicles. These electric vehicles will be more perfect.
