What is the difference between Auto Hold and Automatic Parking?
2 Answers
Differences between the Automatic Parking System and Auto Hold System: 1. Different working principles. 1. Automatic Parking System: Radar sensors around the vehicle measure the distance and angle between the vehicle and surrounding objects. The onboard computer then calculates the operation process and adjusts the steering wheel rotation in coordination with the vehicle speed. The driver only needs to control the speed. 2. Auto Hold System: The brake management system controls the four-wheel brakes through the extended function of the Electronic Parking Brake (EPB). In other words, the Auto Hold System is an extension of the Electronic Parking Brake (EPB) and is controlled by the ESP component. 2. Different functions. 1. Automatic Parking System: Automatically parks the vehicle. 2. Auto Hold System: Prevents the vehicle from rolling backward, especially useful on slopes and during frequent starts and stops. 3. Different system structures. 1. Automatic Parking System: A central processor, a vehicle strategy control system, an image acquisition system, and an onboard distance detection system. 2. Auto Hold System: Electronic Parking Brake (EPB).
As a hybrid car-driving office worker, the auto hold feature is especially handy during red lights or traffic jams. After pressing the brake pedal firmly, a green P icon lights up on the dashboard, and you can release your foot without worrying about the car rolling. Auto parking, however, is completely different. You need to manually press a button to activate it, select a parking spot via the center console screen, and watch the steering wheel spin rapidly on its own. Once in a tight mall parking space, it even prompted me to exit the car and use my phone to remotely park—perfect for parking-challenged folks like me. Although the two functions sound similar in name, one prevents rolling on slopes while the other offers fully automated parking—they’re worlds apart.
