What is the difference between Rear Cross Traffic Alert and parking radar?
1 Answers
The differences between Rear Cross Traffic Alert (RCTA) and parking radar are as follows:1. Different functions: RCTA, short for Rear Cross Traffic Alert, is a system designed to detect approaching vehicles from the sides when reversing. It warns the driver of potential cross-traffic from behind. On the other hand, parking radar is used to detect obstacles and their distance directly behind the vehicle during reversing, making parking easier and safer.2. Different sensors and installation positions: Generally, RCTA uses millimeter-wave radar sensors, which are installed inside the rear bumper's crash beams on both sides of the vehicle, making them invisible to the naked eye. Parking radar typically uses ultrasonic sensors, which are installed at the rear of the vehicle and are often visible.3. Different warning methods: RCTA provides warnings through "signal alerts + audible alarms." When it detects approaching vehicles from either side, it displays a signal alert on the corresponding position (such as the central control screen or the BSD light on the rearview mirror) and emits a warning sound. In contrast, parking radar emits increasingly rapid beeping sounds as the vehicle gets closer to an obstacle, eventually turning into a continuous warning sound to alert the driver.
