Difficulty: EasyABS and Electronic Stability

Match each active vehicle safety system to its primary function during driving.

  • Anti-lock Braking System (ABS)Prevents wheels from locking during emergency braking to retain steering control.
  • Electronic Stability Control (ESC)Corrects sideways skidding and loss of directional control during cornering manoeuvres.
  • Traction Control System (TCS)Prevents driven wheels from spinning when accelerating on slippery surfaces.

Answer

Anti-lock Braking System matches preventing wheel lock under braking to retain steering; Electronic Stability Control matches correcting skids and yaw during cornering; Traction Control System matches preventing wheelspin during acceleration.
Each system addresses a distinct phase of vehicle dynamics: ABS operates under braking to prevent wheel lock-up and maintain steering; ESC acts during cornering or lateral instability to prevent skidding; TCS operates during acceleration to stop driven wheels from spinning.

Step-by-Step Solution

1
Identify the primary role of the Anti-lock Braking System (ABS)
ABS modulates braking pressure to prevent wheels from locking under heavy braking, preserving steering ability.
Locked wheels cannot transfer lateral steering forces.
2
Identify the primary role of Electronic Stability Control (ESC)
ESC constantly monitors vehicle yaw and steering angle to prevent or correct lateral skids (oversteer/understeer).
ESC uses individual wheel braking to keep the car on its intended trajectory.
3
Identify the primary role of the Traction Control System (TCS)
TCS limits engine power and/or brakes spinning wheels when accelerating.
TCS intervenes when driven wheels lose grip due to excessive throttle application.
