ABS System Description

Anti-lock brake system





Structural view
Weather, road surface, and tire condition will affect vehicle performance. The MGH 10 system has been specifically calibrated for the vehicle to achieve the best possible balance between stopping distance, stability, and vehicle steering control.
4-Wheel anti-lock brake systems are designed to provide the driver with:
- Enhanced steering control by enabling the vehicle to move in a driver controlled direction during braking.
- Enhanced braking stability by making the most of available traction (on most road surfaces).

Wheel slip





How well a vehicle can stop is related to how well the tire contact surface grips the road. At 0 % slip, the tire rotates freely. At 100 % slip, the tire and wheel are locked and the weight of the vehicle pushes the locked tires along the road surface. In this situation, vehicle stability may be lost, and steering control will be lost.
Normally, tires will grip to the road surface on average between 10 % and 20 % slip during hard braking. In this slip range, vehicle stopping distances and steering control will be at their best. Some slip is necessary to stop the wheel and achieve maximum braking performance.
