Management of emergency braking



When emergency braking block DSC HU / CM increases the brake fluid pressure by increasing the pressure in the master cylinder, so a large braking force is achieved with less brake pedal is depressed.
System DSC HU / CM uses a built-in sensor of the brake pressure to control the rate of pressure change in the master cylinder, brake assist is activated when the rate of change of pressure exceeds a predetermined value, so the system determines the condition of emergency braking.
System DSC HU / CM calculates the cylinder pressure of the brake mechanism that increases the fluid pressure in the master cylinder to a predetermined value. By changing the pressure in the master cylinder pressure can be increased in the brake cylinder.
In addition to the normal brake fluid pressure, since all the electromagnetic valves are included, a motor drives a pump which increases the pressure in the brake system.
Brake Assist runs at speeds of 17 km / h or higher, and does not turn at speeds of less than 5 km / h.
