Honda City Brake Active System (CTBA)
What is CTBA?
This is a system developed by Honda to detect and prevent a pending forward collision. This
system,
1. Detects a pending forward collision and warns the driver by an alarm and by a message on
the information display
2. If the driver does not respond to the warning and the possibility of collision increases, it
automatically applies brake and a loud buzzer sound is produced.
** Note that, this system activated only within 5~30 km/h **
Alarm + Message
Brake Applied Automatically
Possible Collision
Possibility Increases
How does it detect a possible collision?
This is done by a Laser Transmitter / Sensor Unit installed in the top center of the windshield. It
continuously sends laser beam to the front and detects its reflections from the objects in front. By
this method, it calculates the distance between the objects.
Does my car has this system?
If your car has the sensor, it means you are lucky to have this system. Also there is an indicator
(CTBA) on the dash board that lights ON briefly and goes OFF when you start the car.
