What is the difference between automatic parking and auto hold?
2 Answers
Automatic hold and automatic parking differ in the following aspects: 1. One is for automatic parking into a space; the other is for an automatic handbrake. The automatic parking system refers to a system that can park the vehicle into a space without manual intervention. The auto hold system (AUTO-HOLD) is a technical application that enables an automatic handbrake function while the car is in motion. 2. The function of the auto hold technology is to prevent the vehicle from rolling backward, which is particularly useful on slopes and during frequent starts and stops. The auto hold system, together with the electronic parking brake (EPB: Electrical-Park-Brake, technical name: electronically controlled mechanical parking brake), can form an intelligent braking control system. This integrates the temporary braking during driving with the long-term parking brake function after stopping, and achieves parking braking through electronic control. 3. The electronic parking brake is a technology that realizes parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both achieving parking braking through the friction generated between the brake disc and the brake pads. However, the control method has changed from the previous mechanical handbrake lever to an electronic button. In terms of functionality, the braking control system extends from the basic parking function to the auto hold function.
When it comes to automatic parking and auto hold, I've driven several cars equipped with these features, and the differences are quite significant. Automatic parking is when the system finds a parking space and parks the car for you, such as parallel parking or perpendicular parking, relying entirely on cameras and sensors to scan the surrounding space—you don't need to touch the steering wheel. Auto hold, on the other hand, is different. It maintains the car's position without rolling when you stop, like at a traffic light, by automatically holding the brakes even when you release the pedal. This is especially useful on slopes. The key difference is that automatic parking actively completes the entire parking operation, while auto hold passively maintains the stopped state. I often use these features when driving in the city—automatic parking saves time and effort, while auto hold prevents rear-end collisions for added safety. However, it's important to ensure the system is properly calibrated and not overly relied upon to avoid errors.
