What does the RVM warning light in new energy vehicles indicate?

In new energy vehicles, RVM stands for Rear Vehicle Monitoring system, which alerts the driver when there is a vehicle in the blind spot during lane changes. Below is relevant information about RVM: 1. Introduction: RVM utilizes sub-millimeter wave radar installed on the rear bumper to detect vehicles in adjacent lanes and measure the distance between them. When a lane change poses a potential danger, the system alerts the driver by flashing indicator lights and sounding an alarm. This system employs 24GHz sub-millimeter wave radar, which has a wide detection range and is less affected by adverse weather conditions or sunlight, ensuring accurate detection of approaching vehicles from the rear even at high speeds. 2. Precautions: RVM is a system designed to enhance safe driving by reducing accident risks and driver workload. However, each function has its limitations, and drivers should not overly rely on it. Always remember to practice safe driving.
I encountered the RVM warning light coming on while driving a new energy vehicle, which usually indicates an issue with the Regenerative Vehicle Module. When this light is on, it means the vehicle's regenerative braking system may be malfunctioning, such as failing to recover energy normally or not working during deceleration. Possible causes include dirty sensors, loose wiring, or aging control units. Last time my car had this light on, it was due to a false alarm caused by moisture on the sensor during rainy weather. In such cases, vehicle performance may be affected, such as slower acceleration and reduced range. For safety, I recommend pulling over immediately, turning off the air conditioning to reduce load, and then checking the user manual for specific instructions. If it's not a minor issue, don't attempt DIY repairs—take it to a 4S shop for professional inspection. For prevention, regular maintenance and cleaning of the sensors can help avoid this, especially for owners who frequently drive on gravel roads.
As an ordinary car owner, seeing the RVM light on can be quite concerning. I believe it indicates a problem with the regenerative system module, possibly caused by a sensor malfunction or poor battery connection. While driving, I noticed that after the light comes on, the vehicle loses its regenerative braking function, leading to longer braking distances, which is particularly dangerous in congested urban areas. You can perform some simple checks yourself: first, see if there are any other warning lights on the dashboard, then gently wiggle the battery plug to check if the connection is secure. Avoid tampering with electronic components randomly, as this might damage the fuses. If the light remains on after restarting, it's best to visit a repair shop as soon as possible. Fault lights in new energy vehicles are quite common, and paying more attention to voltage stability can help reduce occurrences.
