What Causes Lane Assistance System Malfunction?
2 Answers
"Parking Assistance System Malfunction" indicates a failure in the vehicle's radar system, rendering the system unusable. The reasons are as follows: The vehicle's parking assistance system is equipped with front and rear radar scanning systems. During parking assistance, the front radar is disabled. This control is achieved through a black wire, which grounds the system when in operation to disable the front radar. However, if this wire becomes disconnected, the system cannot control the front radar, resulting in a parking assistance system malfunction. Relevant information about automotive radar is as follows: 1. Introduction: Automotive radar, as the name suggests, is used for cars or other ground motor vehicles. Therefore, it includes various radars based on different technologies (such as laser, ultrasonic, and microwave), each with different functions. 2. Collision Avoidance Radar: This type of radar measures potential collision hazards on the road ahead based on the vehicle's current direction and speed. It is suitable for situations with low atmospheric visibility and poor judgment (such as short distances between vehicles or high speeds).
I encountered a lane assist system malfunction right after buying my car. Common causes include sensors being covered by dirt, especially the camera under the windshield or the radar on the car body—dust or bird droppings can block the detection of lane markings. On the software side, the system may occasionally freeze, or outdated updates and bugs can cause issues; restarting the vehicle or restoring factory settings can resolve these. Environmental factors like heavy rain or fog can interfere with the camera's view, and strong light may cause the system to misjudge. Power issues, such as unstable battery voltage, can also cause the assist function to automatically turn off. I checked the settings menu to ensure it was enabled—of course, it won’t work if it’s turned off. Regularly cleaning the sensor areas and checking during maintenance can prevent trouble. Safety first—when the system fails, drive manually and pay extra attention to the distance from vehicles ahead and behind.
