What does vehicle control mean?

Vehicle control refers to the automotive control system, which provides car owners with a simple method to control engine start/stop, lights, windows, and locks, offering the first-time use 'ready' function. In simple terms, vehicle control has two main functions: receiving signals from various sensors and calculating corresponding data; based on the calculated data, it controls the fuel injection, ignition, idle air intake, etc., of the car engine to ensure normal operation and minimize engine emissions. Transmitting commands, the trigger signals for speed regulation come from the commands of the vehicle controller. On one hand, the body controller reflects the driver's intent, and on the other hand, it evaluates the reasonableness of the response to the driver based on safety and the operational status of the vehicle's electrical system, ultimately executing or partially executing the command. The driver's intent is expressed through the accelerator and brake pedals and transmitted to the vehicle controller. Adjusting the operational status of equipment, the specific commands given by the body controller to the motor controller include the following related to the powertrain: acceleration, deceleration, braking, and parking. The motor controller responds by altering parameters such as power current, voltage, and frequency to ensure the motor's operational status meets the controller's requirements.
I have always been passionate about studying automotive technology. For me, the term 'car control' primarily refers to how a driver precisely manages the vehicle's direction, speed, and stability. The steering wheel is the core, with different designs affecting steering feedback—for example, electric power steering makes city driving easier, while mechanical steering offers a more raw feel. Throttle control dictates acceleration response, and electronic throttle bodies optimize linear acceleration. Braking ensures safe deceleration, with ABS preventing wheel lockup on slippery surfaces. The suspension system is also crucial: stiff suspensions enhance cornering control, while soft suspensions sacrifice precision for comfort. I’ve modified shock absorbers, and after reinforcement, high-speed cornering became more stable. Stability control systems like ESC automatically correct skids, boosting confidence in rainy conditions. Good car control not only ensures safety but also enhances driving pleasure. Regular checks of steering fluid and brake pads are recommended to maintain reliability.
