Applies the brake when the automobile, if the wheel holds the dead slipping, between the wheel and the road surface lateral will attach the strength completely to vanish. If only is the front wheel (wheering wheel) applies the brake to hold the dead slipping but the trailing wheel also to roll, the automobile will lose changes the ability. If only will be the trailing wheel applies the brake to hold the dead slipping but the front wheel also to roll, even if receives not not in a big way lateral does 扰力, the automobile also will produce sideslips (flings tail) the phenomenon. These extremely are all easy to create the serious traffic accident. Therefore, automobile in applying the brake time did not hope the wheel applies the brake to hold the dead slipping, but is hoped the wheel applies the brake to the side edge slippery condition. Knew by the experiment, automobile wheel skidding rate when 15% ~ 20%, between the tire and the road surface has the biggest coefficient of adhesion. Therefore in order to fully displays this kind between the tire and road surface latent is attaching the ability, at present all equipped on of the majority vehicles has guarded against hugs dies the braking system (Antilock Brake System), was called ABS.

Applies the brake when the automobile, if the wheel hugs dies the slipping, lateral adhesion between the wheel of and the road surface completely will vanish. If only is the front wheel (wheering wheel) applies the brake to hug dies the slipping but the trailing wheel also to roll, the automobile will lose changes the ability. If only will be the trailing wheel applies the brake to hug dies the slipping but the front wheel also to roll, even if receives not not in a big way lateral does the disturbing force, the automobile also will produce sideslips (flings tail) the phenomenon. These extremely are all easy to create the serious traffic accident. Therefore, automobile in applying the brake time did not hope the wheel applies the brake to hug dies the slipping, but is hoped the wheel applies the brake to the side edge slippery condition.

Therefore in order to fully displays this kind between the tire and road surface latent of adheres to stick cohere the ability, at present all equipped on the majority vehicles has guarded against hugs dies the braking system (Antilock Brake System), was called ABS.
