My friend Tuan, who lives in Hang Bong street, recently bought a new Dongfeng truck for his business. He was thrilled with his shiny new vehicle. However, he soon started complaining about the difficulties of reversing such a large truck with its many blind spots. He had a few near misses, which left him quite shaken. I advised him to install a car reverse sensor system. A few days later, a grateful Tuan thanked me profusely, saying that since getting this “silent guardian,” reversing had become much easier and safer.

So, what makes car reverse sensors so effective? Let’s explore this with Hanoi Trucks!

Car Reverse Sensors: The “Magic Eye” for Safe Reversing

What are Car Reverse Sensors?

Car reverse sensors are intelligent electronic systems that use ultrasonic waves to detect and alert the driver to the distance between the rear of the vehicle and obstacles when reversing or parking.

Structure and Working Principle

A typical car reverse sensor system consists of:

Sensor probes (usually 2 to 8) installed on the rear bumper.
A central control unit.
A display screen or warning buzzer.

When the vehicle is in reverse, the sensors emit ultrasonic waves. If an obstacle is encountered, the waves bounce back to the sensor. Based on the time it takes for the ultrasonic waves to return, the control unit calculates the distance to the obstacle and issues a warning via an audible beep or a visual display, allowing the driver to react accordingly.

Benefits

Assists in safe reversing, especially in low-light conditions and tight spaces with limited visibility.
Minimizes the risk of collisions and scratches when reversing or parking.
Provides peace of mind and confidence for the driver.

Types of Reverse Sensors

There are various types of reverse sensors available on the market, with the most common being:

2-sensor systems.
4-sensor systems.
6-sensor systems.
8-sensor systems.

The more sensors a system has, the wider and more accurate its obstacle detection capability.

Sensor Type	Estimated Price (VNĐ)
2-Sensor System	From 500,000
4-Sensor System	From 800,000

Frequently Asked Questions about Car Reverse Sensors

Can reverse sensors be installed on all types of cars?

Most car models today, from sedans to trucks and pickups, can be equipped with reverse sensors.

Which type of reverse sensor is best?

The best type of sensor depends on your individual needs and budget. If you frequently reverse or park in tight, crowded areas, a system with more sensors is recommended for enhanced obstacle detection.

Where can I find reliable reverse sensor installation services in Hanoi?

You can visit reputable auto garages in Hanoi, such as those in Nguyen Van Cu or Long Bien streets, or inquire about installation services at authorized truck dealerships like Hanoi Trucks.

Do reverse sensors affect the feng shui of a car?

Some people believe that adding equipment to a car should adhere to feng shui principles to bring good luck and fortune to the owner. However, reverse sensors are safety devices and do not have any spiritual implications.
