What does MEM mean?

The MEM button on the steering wheel can directly recall the cruise control memory for convenient selection. The cruise control system is also known as speed control device, speed control system, or autonomous driving system. It is used to maintain a constant vehicle speed. Once set to cruise mode, the engine's fuel supply is controlled by the computer, which continuously adjusts fuel delivery based on road conditions and driving resistance to maintain the preset speed. The specific functions of cruise control are as follows: 1. Cruise control function: The system compares pulse signals from the speed sensor with the preset speed through the cruise control module, then issues precise electronic commands to ensure optimal fuel delivery at the set speed. 2. Electronic fuel-saving function: By intelligently optimizing throttle opening angle and duration, it effectively filters out erratic signals from electronic throttle sensors caused by bumpy roads or poor driving habits. Precise fuel injection calculations ensure complete fuel combustion for maximum efficiency. 3. Throttle acceleration function: Enhances throttle response sensitivity. When the system detects driver acceleration intent, it opens the throttle as quickly as possible, improving throttle responsiveness. The controller calculates throttle signal change rate based on pedal depression depth and duration - faster changes indicate stronger acceleration demand, resulting in quicker throttle response and noticeably enhanced driving dynamics. 4. Speed limit setting function: The controller sets maximum output throttle signals according to predefined speed limits. When throttle output cannot exceed this maximum, speed restriction is achieved. 5. Brake failure warning function: Monitors brake circuit signals and alerts the driver via warnings when brake circuit or fuse malfunctions occur.
