BLIND SPOT MONITORING (BSM) CONTROL MODULE


id092200027400


Purpose

•  Controls the blind spot monitoring (BSM) system.

Function

•  The BSM control module emits microwaves to detect an oncoming vehicle's position and speed information via the reflected microwaves.
Note
•  The detection ability of the blind spot monitoring (BSM) control module has limitations. In the following cases, the detection ability may lower and the system may not operate normally.
―  The rear bumper near the blind spot monitoring (BSM) control module has become deformed.
―  Snow, ice or mud adheres to the blind spot monitoring (BSM) control module on the rear bumper.
―  Under bad weather conditions such as rain, snow and fog.
•  Under the following conditions, the blind spot monitoring (BSM) control module cannot detect target objects or it may be difficult to detect them.
―  Stationary objects on a road or a road side such as small, two-wheeled vehicles, bicycles, pedestrians, animals, and shopping carts.
―  Vehicle shapes which do not reflect radar waves well such as empty trailers with a low vehicle height and sports cars.
•  Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will be blocked causing the system to not operate normally.
•  The BSM system is controlled based on the detected vehicle position and speed information.
•  A self-diagnostic function has been adopted.

Construction

•  The BSM control module and radar have been integrated.
•  Microwaves are emitted from the radar.
•  Two control modules are positioned on the left and right sides of the body inside the rear bumper.

Operation

•  The BSM control module emits microwaves to the vehicle rear to detect the obstruction via the reflected microwaves.

Radar Emitting Area

•  Cross-directional: 1 m {3 ft} toward the front of the vehicle, and 7 m {23 ft} toward the rear of the vehicle from the rear end of the vehicle (total, 8 m {26 ft}).
•  Lateral direction: 0.5—3.8 m {2—12 ft} from the side of the vehicle (total, 3.3 m {11 ft}).

•  When the vehicle is cornering, such as turning into an intersection, the shape of the warning area on the inner side changes.
―  Cross-directional: Length of the vehicle rear changes depending on the steering angle.
―  Lateral direction: Angle of the warning area changes along the vehicle’s turning orbit.
