| TCS is a device that maximizes accelerating and climbing abilities by preventing wheel slipping when the car accelerates or moves forward from a stopped position. |
 |
 BTCS(Brake TCS) |
| If the wheels begin to spin when accelerating or moving from stopped position,
this brake control system decreases torque and minimizes the slip by activating the brake, thereby improving accelerating
and climbing abilities. The operation principles are the same as those of ABS. For easy understanding, you may wish to think
of ABS as operating when brake pressure is applied and TCS as operating when using the accelerator. With respect to ABS,
however, brake fluid pressure is related to the pressure applied to the brake pedal and is regulated through a separate
structure, the ECU and HCU for ABS are changed for the use in TCS with all other parts remaining the same. |
| FTCS(Brake + Engine TCS) |
| If the wheels begin to spin when accelerating or moving forward from a
stopped position, TCS minimizes slippage by applying brake pressure to decrease wheel torque. In addition, the system
decreases engine torque as well. When the wheels begin to spin, TCS communicates with the engine and the automatic
transmission, decreases engine output, and applies brake pressure to decrease the driving torque. The decrease in
engine output occurs through throttle, ignition time, and fuel supply adjustments, among others. Hyundai Motor Company selects the
most appropriate methods for each model. TCS is also activated during high-speed turns to ensure a maximum level of safety. |

Wheels skid because the driving force of the wheels is too powerful for a particular road surface or grade. |
TCS prevents wheel slippage by properly controlling engine torque and decreasing the turning force of the wheels. |
