What is an Electronic Stability Program (ESP) System?
- A system that prevents the possibility of a braking system malfunction.
- A system that prevents the possibility of a steering system malfunction.
- Correct answer: A system that prevents loss of control while skidding and keeps the vehicle on course.
- A system that prevents the vehicle’s wheels from locking during an emergency braking, thus maintaining the vehicle’s steering.
Why this is the answer
The correct answer in the official bank: A system that prevents loss of control while skidding and keeps the vehicle on course.
ESP uses sensors to detect when the vehicle starts to skid or drift away from the direction the driver is steering. It automatically brakes individual wheels and may reduce engine power, preventing loss of control and keeping the vehicle on course. Preventing wheel lock during emergency braking is the job of ABS, and neither system prevents brake or steering malfunctions.
