IT House May 14 news, yesterday evening, BYD announced that in order to improve the driving performance of electric vehicles while laying a solid foundation for safety, BYDExclusively developed the intelligent torque control system iTAC(Intelligence Torque Adaption Control). IT Home was informed that,iTAC technology will be carried on the new e-platform 3.0 models.

BYD said that in terms of response speed,The recognition accuracy of iTAC is improved by more than 300 times, and the change trend of wheel speed can be predicted more than 50ms in advance. When the grip of the wheel end is abnormal but there is no slippage, the system has already recognized the abnormal grip and adjusted it in advance to restore the stability of the vehicle.
▲ The vehicle response speed under iTAC is significantly improved
In terms of control strategy, iTAC, on the basis of pre-judgment, aims at the characteristics of fast motor response and more accurate speed adjustment.Provides a variety of ways to transfer torque, appropriately reduce torque and output negative torque.
▲ iTAC uses torque transfer for vehicle control
In order to verify the safety and maneuverability of iTAC for driving on low-adhesion roads,BYD conducts all-round performance tests in extremely cold environment.
▲ 0-60km snow straight line acceleration
▲ Ice-asphalt docking pavement starts
▲ Snow angle step test
▲ Snow ring test
BYD pointed out that according to the above test results,iTAC can effectively improve the extreme performance of the vehicle when driving on low-adhesion roadsso that ordinary consumers who are not professional racing drivers can also enjoy the fun of driving the vehicle.
