What is the difference between electronic parking brake and auto hold in cars?
2 Answers
Here is the difference between electronic parking brake and auto hold in cars: 1. Different braking duration: Auto hold is a temporary braking system, while the electronic parking brake is for long-term braking. Together, they form an intelligent braking control system that integrates temporary braking during driving and long-term braking after parking, both achieved through electronic control. 2. Different usage methods: The electronic parking brake works like the handbrake in a manual transmission car—you need to release it when driving and engage it when parking. Auto hold, on the other hand, automatically engages and releases the handbrake during driving. The electronic parking brake is suitable for use before and after long-term parking, while auto hold is suitable for stop-and-go traffic conditions.
The difference between electronic parking brake and auto hold, I've experienced quite a bit while driving before. The electronic parking brake is like an upgraded version of the handbrake—you press a button after parking, and it locks the wheels, suitable for long-term parking or on slopes to prevent rolling; whereas auto hold automatically applies the brakes when you come to a stop while driving, so you don't have to keep pressing the pedal, and it releases when you press the accelerator, which is especially convenient in traffic jams or at red lights. The electronic parking brake requires manual operation, mainly for parking safety; auto hold activates automatically, aiming for driving comfort and convenience. I've driven on some steep slopes, relying on the electronic parking brake to secure the vehicle, while in city traffic, auto hold frees up the right foot and reduces fatigue. The core difference: one is for securing the vehicle after complete stops, the other is automatic assistance during brief stops.
