What is the Function of Vehicle Stability Control System?
1 Answers
Vehicle Stability Control System, also known as Anti-Skid Control System, is an active safety system developed by Toyota that significantly improves vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the system can quickly detect and take corresponding braking measures, such as individually controlling each tire while reducing engine output to maintain vehicle stability. Its functions include the following three aspects: 1. During emergency braking, the ABS function prevents wheel lock-up. When wheels slip, the TCS function controls engine output and wheel braking to prevent wheel spin. 2. When the vehicle is making sharp turns, swerving to avoid suddenly appearing cars or animals, or experiencing understeer causing the vehicle to slide outward or oversteer causing the vehicle to cross the centerline or even spin, the system uses computer control to adjust engine output and apply braking force to individual wheels (with varying intensity) to counteract understeer or oversteer, thereby enhancing dynamic driving stability. 3. System Features: Compared to other active safety systems like ABS, the VSC system has three main characteristics: Real-time Monitoring: The VSC system continuously monitors the driver's inputs (steering, braking, throttle, etc.), road conditions, and vehicle dynamics, sending constant instructions to the engine and braking system. Active Intervention: While safety technologies like ABS primarily intervene based on driver actions, they cannot regulate the engine. The VSC system actively adjusts the engine throttle to modify engine speed and modulates the driving/braking force on each wheel to correct excessive understeer or oversteer.
