Hill hold control
If the brake pedal is applied to hold the
vehicle on a hill, this function will continue to
apply the brakes for 2 seconds after the
pedal is released to assist a smooth start.
Brake-steer
Brake steer offers the benefits of a torque
vectoring differential, but is integrated into
the braking system reducing weight and
providing excellent speed of response.
Torque vectoring gives the differential the
ability to change the amount of power that
is sent to each of the rear wheels to provide
optimum stability and traction.
If the system detects that the vehicle is
starting to understeer through a corner, the
inside rear brake is gently applied. This helps
to increase the yaw rate of the vehicle,
making the vehicle feel more resistant to
understeer. The lateral ‘g’ force is also
increased giving better handling
characteristics.
If the driver uses too much throttle exiting a
corner, the inside rear wheel increases
speed, which without brake steer could
cause the vehicle to become unstable. In this
situation, brake steer will again gently apply
the brake on the inside rear wheel, thereby
restoring traction and stability.
Electronic brake pre-fill
If the accelerator pedal is suddenly released,
the electronic brake pre-fill function
immediately brings the brake pads into
contact with the discs, ensuring rapid
braking.
