What does VSA mean?

1 and VSA (vehicle stability assistance) are vehicle stability control systems, which have advanced control systems in the world to improve vehicle stability and driving safety.

2.VSA system not only has the traditional functions of anti-lock braking (ABS) and traction control (TCS), but also adds the anti-skid control function.

3.ABS anti-lock braking system: to prevent the wheels from locking when braking, especially when braking on wet roads, to avoid the tail flick of the vehicle, to maintain the steering ability of the vehicle and to improve the safety when braking.

4.TCS traction control system: prevent the wheels from idling and slipping when the vehicle starts or accelerates, so as to avoid slow or out-of-control acceleration due to slipping and improve acceleration performance and safety performance. This function is very practical for vehicles to start and accelerate on ice, snow or other slippery roads.

5. Anti-sideslip function: According to data, 60% of traffic accidents that cause death are caused by vehicle sideslip, so sideslip and tail flick are extremely dangerous cold-blooded killer in automobile driving.

Extended data:

The VSC system has three characteristics:

1, real-time monitoring

The VSC system can monitor the driver's control actions (steering, braking and throttle, etc.). ), road information and vehicle movement state, and constantly send instructions to the engine and braking system.

2. Active intervention

Safety technologies such as ABS mainly interfere with the driver's actions, but cannot adjust the engine. VSC system can adjust the engine speed and the driving force and braking force of each wheel by actively adjusting the engine throttle to correct the oversteer and understeer of the car.

Step 3 remind in advance

When the driver operates improperly or the road surface is abnormal, VSC system will remind the driver with warning light.
