What does it mean when a vehicle is under control?

Vehicle is under control and cannot be used freely. Cold engine warm-up: Proper warm-up helps form an "oil film" between engine components to reduce wear. Timely gear shifting: When driving manual transmission vehicles during the break-in period, shift gears promptly and appropriately. Avoid incorrect behaviors like high gear with low RPM or low gear with high RPM, and don't use a single gear for extended periods. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual. After reaching certain mileage or time intervals, promptly conduct inspections and maintenance, including oil and filter changes, along with a comprehensive chassis system check. Avoid emergency braking: Emergency braking not only impacts the breaking-in brake system but also increases shock loads on the vehicle's chassis and engine.
As an ordinary person who drives frequently, I believe that vehicle control means the car is completely within the driver's command, with no unexpected skidding or loss of control. This usually happens during normal driving, such as when turning, braking, or accelerating—the driver feels everything is smooth and steady, with direct and reliable vehicle response. This relies on the coordinated work of various vehicle systems, like the Electronic Stability Control (ESC), which intervenes when wheels begin to lock or skid, adjusting braking force to help stabilize the car. I pay special attention to this in my daily driving, especially in rain, snow, or on highways, as maintaining vehicle control can prevent many dangerous situations. If I encounter road bumps or signs of skidding, I immediately reduce speed and check tire pressure and maintenance records. Overall, it's not just a technical term—it's closely tied to the safety of family trips.
From the perspective of an automotive test engineer, vehicle control involves the precise operation of the vehicle's dynamic systems. This means that while driving, the chassis, steering, and braking components work in harmony without the risk of losing traction or directional control. This is commonly observed during closed-circuit testing, such as simulating emergency lane changes or slippery road conditions. We monitor sensor data like wheel speed and steering angle to determine if the vehicle remains under control. Relevant technologies include ABS (Anti-lock Braking System) and traction control systems, which quickly adjust to prevent skidding. Neglecting maintenance, such as tire wear or aging brake fluid, can lead to loss of control. Therefore, I recommend that car owners regularly perform wheel alignment and system self-checks. When driving, maintaining a reasonable speed makes it easy to keep the vehicle under control.
