Traction control systems gives the driver more control, helps maintain stability and improves handling in different driving conditions. When the traction control system senses a tire slipping or losing traction, it automatically activates your brakes or slows down engine speed, depending on the vehicle's system. The goal is to get the wheel moving slowly so that spin is minimized until tire traction returns. The system uses sensors to detect differences in wheel speed, then applies the brakes to reduce the amount of power sent to the tires. Traction control systems are extremely helpful when driving in adverse weather conditions, or when driving on gravel roads.
Some systems transfer power to the wheel with good traction control before slippage begins.
The braking system controls each wheel. Reduces power to the slipping wheel or wheels at any speed. Some drivetrain traction control systems perform all four functions simultaneously. Traction controls can generally be turned on and off. Drivers should turn traction controls off if they are stuck in a snowdrift when you would want the tires to spin, for example.
