VCU in new energy vehicles is the core electronic control unit that implements vehicle control decisions. It is generally only equipped in new energy vehicles, while traditional fuel vehicles do not require this device. New energy vehicles are those that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices). Extended information: 1. The working principle of VCU in new energy vehicles: The VCU collects signals from the accelerator pedal, gear, brake pedal, etc., to determine the driver's intentions. By monitoring vehicle status information (such as speed, temperature, etc.), the VCU processes and judges the data, then sends control commands for the vehicle's operating status to the power system and the power battery system, while also controlling the working mode of the onboard auxiliary power system. The VCU has functions for diagnosing, protecting against, and storing faults in the entire vehicle system. 2. The structural composition of VCU: It includes a housing, hardware circuits, underlying software, and application layer software. The hardware circuits, underlying software, and application layer software are the key core technologies of the VCU.

Why is the Volkswagen Bora's wiper making loud noise?

Volkswagen Bora's wiper making loud noise is due to aging wiper blades. Maintain cleanliness: When there are streak marks on the glass surface, the wiper blade may be dirty. You can sprinkle alcohol on a towel and wipe the surface of the wiper blade. Cleaning once a month can improve the performance of the wiper. Check the rubber: If the wiper makes abnormal noises during operation, it may be due to aging or cracks in the rubber blade. If the wear is not severe, you can use sandpaper to smooth out rough spots on the surface. Avoid sunlight: Park the car in a shaded area where it is not exposed to sunlight, such as a garage. Summer is a season that is particularly harsh on cars. Wiper blades are rubber products, and sunlight will only accelerate the aging process. Refill fluid: Adding plain water directly to the windshield washer fluid reservoir is not conducive to the maintenance of the windshield and wiper blades in the long run. To ensure the longevity of the components, always use proper windshield washer fluid. Refill the washer fluid in time to be prepared for unexpected needs.

What do the plus and minus signs on the Envision's gear shift mean?

The plus and minus signs on the Envision's gear shift represent upshift and downshift respectively. Manual mode: The plus and minus signs on the Envision's gear shift indicate the manual mode of the automatic transmission. When the gear is in D (Drive) automatic mode, you can switch the gear lever from D to the plus/minus side during normal driving to activate manual mode. Pushing the lever toward the plus sign will accelerate the vehicle, and repeatedly pushing it upward will continuously increase the speed. Pushing it toward the minus sign will decelerate the vehicle. Model introduction: The Buick Envision is a compact SUV launched by SAIC-GM Buick.

Why Can't a Single Car Door Open?

Reasons why a single car door cannot open: Child lock is activated, lock cable malfunction, hinge lock pin deformation, door limiter failure. Child lock activated: When closing the door, always check if the child lock is deactivated. If the door won't open, use a flathead screwdriver to turn the child lock to the off position. Lock cable malfunction: When this occurs, the door cannot be opened from inside the car because the malfunctioning cable directly affects the lock mechanism. Hinge lock pin deformation: If the door is subjected to external force, it may cause deformation of the door hinge and lock pin, which is another reason why the door won't open. Door limiter failure: When this issue arises, opening the door becomes very difficult or impossible. The solution is to replace the door limiter with a new one to ensure smooth operation.

What does it mean when the starting city has no offline data?

When the starting city has no offline data, it means the navigation data needs to be updated. The navigation system does not have the offline map package for this city. First, check if it's a network issue, then verify if there's any signal interference, and finally, see if the starting city has the relevant data. Internal structure of a car navigation system: It integrates a GPS antenna and receiver, automatically calculates and displays positioning results without requiring an internet connection. However, if the positioning data needs to be transmitted to remote devices, a GPRS module is usually integrated to facilitate data transmission over the public network. Functions of a car navigation system: The car navigation system features GPS global satellite positioning, automatic voice navigation, optimal route search, and more. It allows drivers to know their exact location at any time while driving and helps them take the shortest route, ensuring a smooth journey.
