What is the difference between automatic parking and auto hold?
2 Answers
The differences between automatic parking and auto hold are as follows: 1. Different working principles: The automatic parking system measures the distance and angle between the vehicle and surrounding objects through radar probes installed around the vehicle. Then, the onboard computer calculates the operation process and adjusts the steering wheel rotation in coordination with the vehicle speed. The driver only needs to control the speed. On the other hand, the auto hold system controls the braking of all four wheels through an extended function of the electronic parking brake in the brake management system. In other words, the auto hold system is an extended function of the electronic parking brake, controlled by the ESP component. 2. Different functions: The automatic parking system automatically parks the vehicle into a space, while the auto hold system prevents the vehicle from rolling backward, which is particularly useful on slopes and during frequent starts and stops.
As an experienced driver, I've found that automatic parking and auto hold are quite different. Automatic parking helps the car park itself into a space, such as in parking lots or parallel parking on the roadside. It uses cameras and radar to scan the position and automatically controls the steering wheel and brakes to operate, saving the driver from manual adjustments. However, it can sometimes make minor mistakes in complex environments. On the other hand, auto hold is a function activated when stopping to wait, such as at traffic lights or in traffic jams. After pressing the button, you don't need to keep your foot on the brake; the car automatically holds to prevent rolling back, which is especially useful when starting on a slope. The difference lies in one focusing on the parking action, while the other targets short-term stationary states. One requires an activation process, while the other is often a default setting. In daily driving, automatic parking is suitable for beginners to reduce stress, but auto hold benefits everyone, especially in reducing driving fatigue. I believe understanding these can help better utilize technology and avoid unexpected risks from over-reliance.
