다이믈러-클라이슬러 Mercedes Car Group 스마트 세계에서 가장 안전한 경차 초고강성 차체 But before the tridion safety cell and the crash management system have a chance to prove what they’re made of, the active damage prevention features take effect and prevent anything untoward from happening. esp®: Electronic Stability Programme. The 2nd generation comes with the Electronic Stability Programme esp® as standard, the likes of which are commonly encountered in large saloon cars. The esp® sensors immediately sound the alarm when your car is in danger of swerving and recognise dangerous situations in good time. esp® immediately throttles the engine torque and specifically brakes individual wheels, in order to stabilise the car. abs: Anti-lock Braking System. With EBD. The Anti-lock Braking System abs prevents the wheels from locking during emergency braking. This ensures that the vehicle remains steerable, regardless of how heavily the brakes are applied, and that the car does not swerve, even on varying road surfaces. The Electronic Brake-force Distribution EBD between the front and the rear axle optimises the abs enabling you to steer safety whilst slamming on the brakes. CBC: Cornering Brake Control. There is a varying load on the wheels when cornering. If you brake in a bend, CBC ensures optimal distribution of the brake force over the wheels. And your smart fortwo coupé stays on track. Electronic Brake Assist. If you step on the brake fast, but not hard enough, Hydraulic Brake Assist will assist you with automatic emergency braking. It automatically initiates controlled emergency braking and generates the high braking pressure necessary for abs control. Brake Assist can save you those vital few metres in a tricky situation. ASC (Acceleration Skid Control) If the drive wheels are at risk of spinning on slippery terrain, ASC prevents loss of tractoin by braking the wheel with the most tractoin slip. This is equivalent to the function of a differential lock. ETC (Engine Torque Control) prevents instability when changing down on slippery roads by slight, automatic acceleration or disengaging the clutch. HSA (Automatic Hill Start Assist). With HSA, you’ll never have to apply the handbrake again when pulling away on a slope. After lifting your foot from the brake pedal, the wheels remain braked for 0.7 seconds. This gives you enough time to unhurriedly move your foot to the accelerator, without the car rolling backwards.
