Blind Spot Monitoring With Rear Cross Path Detection: Notes

DESCRIPTION

The Blind Spot Monitoring (BSM) with Rear Cross Path (RCP) Detection system can consist of the following components:

The BSM system, if enabled in the radio, monitors the rear blind zones on both sides of the vehicle using radar detection. If a vehicle is sensed in one of the blind spot zones, the driver will be notified by a blind spot indicator lamp that illuminates an icon on the outside rear view mirror on the side of the vehicles where the vehicle is detected.

The RCP detection monitors for vehicles perpendicular to the rear of the vehicle when the host vehicle is shifted into R  everse. The system provides feedback to the driver by using audible chimes and visual icons. The visual and audible alerts correspond to the side of the approaching vehicle.

The BSM system:

• Monitors the vehicle's blind spots.
• Notifies the driver when another vehicle is present.
• Uses radar sensors located in the sides of the tail lamps.
• Illuminates icons in the outside review mirror glass.
• Chimes when the driver selects a turn signal on the side that has a vehicle in the zone.
• Notifies driver of vehicles in the blind spot areas when changing lanes, passing vehicles, or if being passed.
• RCP detection notifies the driver via a chime if a vehicle is crossing the host vehicle's path when the host vehicle is in reverse.
• The driver can turn the system OFF, ON or ON with Chime. (Note: In RCP mode the chime can not be disabled it is always active)

OPERATION 

When the vehicle speed exceeds 10 km/h (6 mph) and the Left Blind Spot Sensor (LBSS) or the Right Blind Spot Sensor (RBSS) detects an object within 24 km/h (15 mph) of the vehicle speed passing through the monitored zone from the rear of the vehicle, the LBSS sensors will request a blind spot indicator request to the DDM. The DDM or PDM controls the indicator lamp through a Pulse Width Modulated (PWM) circuit to the mirror on the side of the vehicle that the object is detected. If the driver attempts to enter the zone where the object has been detected and with the turn signal activated, the sensor will send out two additional requests over the Controller Area Network - Interior High Speed (CAN-IHS) bus to the BCM. The BCM then sends these messages to:

• The Radio, if the vehicle is NOT equipped with an Amplifier (AMP), to mute audio speakers.
• Or, If equipped. to the AMP to request a auditory chime.

There are three operating modes for the BSM system:

• OFF: All visual and audible alerts related to objects of interest in the blind sport zone are suppressed.
• ON with blind spot indicator only
• ON with blind spot indicator and chimes

Rear Cross Path (RCP) detection system:

• Uses the LED icons on the outside mirrors to warn of vehicles approaching. The alert corresponds to the side that the vehicle is approaching from.
• Is activated when the vehicle is in R  everse gear and the blind spot system is enabled to ON or ON with Chime selected in the Radio options menu.

The RCP detection system monitors the rear detection zones for vehicles that are moving toward the sides of the vehicle with a minimum speed of 13 km/h (8 mph).
