DRIVING
●
FORWARD COLLISION MITIGATION (FCM)*
Operating principle
The FCM assesses the risk of pre﹣collision by detecting the relative distance
and speed with the vehicle ahead in the same path according to the signal from
the MMW radar installed on the front of the vehicle and the IFC installed on
the front windshield and the driver's other operations (such as depressing the
brake pedal or accelerator pedal), gives an alarm to remind the driver to take
measures in time in case of a collision risk. When the driver is braking while
the braking force is insu󰀩cient to avoid a collision, the system will automatically
increase the braking force to avoid or alleviate the collision.
The FCM consists of the FCW and the AEB.
Detectable objects
● Vehicles
● Two﹣wheelers
● Pedestrians
FCW
FCW issues an alarm for impending collision to alert the driver by detecting
objects ahead according to the signal from the MMW radar installed on the front
bumper and the IFC installed on the front windshield.
AEB
When a collision is about to occur, the system will issue an alarm to alert the
driver that the vehicle is ready to apply emergency braking according to the
signal from the MMW radar installed on the front bumper and the IFC installed
on the front windshield, and then will assist in braking and activate the active
brake assist function.
Warning:
The FCM can improve the driving safety, but it is still subject to the limitations
of laws of physics, and thus shall never be used for risky driving. The driver
must always be ready to apply the brake to reduce the vehicle speed or avoid
obstacles.
