What is the difference between an electric trunk and a sensor-activated trunk?
3 Answers
The differences between a sensor-activated trunk and an electric trunk are as follows: 1. An electric trunk refers to a trunk that can be opened and closed electronically. There is a door-closing button inside the trunk door, and by pressing this button, the trunk door can close automatically without manual intervention. 2. A sensor-activated trunk refers to a trunk equipped with sensors inside the vehicle, allowing the trunk to be opened or closed via sensing. Simply waving your foot under the sensor can open the trunk. 3. A trunk with sensors is very convenient. When your hands are occupied, you can easily open the trunk by moving your foot within the sensor's range.
I've been driving cars with these features, so I can tell the most direct differences. The electric trunk requires you to press the key or button with your fingers to open and close it, just like operating a traditional remote. The sensor-activated trunk is more advanced—just stand behind the car and give a gentle kick, and the sensor detects it and opens automatically without touching anything. Once at the supermarket, I was carrying a big box, and with just a lift of my foot, the trunk popped open, saving me the hassle of digging out the key. However, the sensor type also has drawbacks: in heavy rain or when covered in dust, the sensor occasionally fails. The electric one, though not as cool, can still be operated manually if needed. In terms of installation cost, the sensor-activated type is much more expensive, with an additional cost of over a thousand yuan compared to the electric one. Overall, the convenience of the sensor-activated trunk is significantly improved, making it more suitable for young people who often carry heavy items.
Many car owners have asked about this difference during repairs, so let me briefly explain. An electric trunk is motor-driven, allowing you to control its opening and closing via a switch or remote button. In contrast, a sensor-activated trunk relies on radar or camera sensors to detect movements, such as a foot-kick signal, to automatically trigger opening. Technically, sensor-activated systems have more complex circuitry and are prone to malfunctions due to dirt or aging wiring, making repairs more expensive. Electric trunks, however, have simpler structures and can often be fixed by replacing the motor or wiring. From a safety perspective, sensor-activated trunks may accidentally trigger in hazardous situations, like in crowded parking spots with obstacles. It's recommended to regularly clean the sensors during maintenance to reduce risks. For daily use, sensor-activated trunks save time and effort, but their practicality depends on personal preference.
