Zorluk: ZorABS and Electronic Stability

Electronic Stability Control (ESC) uses the vehicle's braking system to correct a skid, but it can only apply braking force when the driver is actively pressing the footbrake.

Cevap: Cevap

Cevap

False
The statement is false because Electronic Stability Control (ESC) does not require the driver to press the brake pedal to function. When onboard sensors detect a deviation between the steering wheel angle and the vehicle's actual direction of travel, the ESC system automatically engages the hydraulic brake pump to apply braking force to individual wheels and may cut engine power to restore vehicle stability.

Adım Adım Çözüm

1
Identify the primary function and operating mechanism of Electronic Stability Control (ESC).
ESC continuously monitors vehicle trajectory using steering angle, wheel speed, and yaw rate sensors to detect loss of lateral traction (understeer or oversteer).
Understanding sensor inputs establishes how the system detects directional instability.
2
Analyze how ESC delivers corrective intervention during dynamic instability.
The system utilizes an internal hydraulic pump to independently apply precise braking force to specific individual wheels and reduce engine power.
To counteract rotational spin or ploughing off course, corrective yaw moments must be generated immediately without relying on driver pedal action.
3
Evaluate the truth value of the stem statement.
The claim that ESC can only apply braking force when the driver presses the footbrake is false.
ESC is an autonomous active safety system designed to intervene during cornering, sudden swerves, or acceleration regardless of driver foot position.
