BLIND SPOT MONITOR SYSTEM SYSTEM DESCRIPTION

CAN COMMUNICATION SYSTEM

1. The blind spot monitor system uses CAN communication to transmit data between the right and left blind spot monitor sensors and each ECU.

2. If there is a problem in the CAN communication, the right and left blind spot monitor sensors output a CAN communication malfunction DTC.

3. Each CAN communication line has a particular length and route. Therefore, emergency repair using bypass wiring, etc. is not possible.

GENERAL

1. The blind spot monitor system has the blind spot monitor function and RCTA function.

   
   

   1. Blind spot monitor function

      
      

      • The blind spot monitor function is a function that assists the driver in making the decision to change lanes. The function uses quasi-millimeter wave radar to detect vehicles that are traveling in an adjacent lane in the area that is not reflected in the outer rear view mirror assembly. The function advises the driver of the existence of a vehicle by illuminating the outer rear view mirror indicator on the outer rear view mirror assembly.

      • If the turn signal switch is operated while the outer rear view mirror indicator on an outer rear view mirror assembly is illuminated, the indicator starts blinking to give additional warning to the driver.

   2. RCTA function (w/ RCTA)

      
      

      • The RCTA function is a function that informs the driver of an approaching vehicle from diagonally behind. The function uses quasi-millimeter wave radar to detect the positions of and relative speed to a vehicle. When the function determines that a vehicle is approaching this vehicle, this function informs the driver of it using the indicators and buzzer.

FUNCTION OF COMPONENTS

OPERATION DESCRIPTION

1. Operation description of the blind spot monitor function

   
   

   1. Operation conditions

      
      

      • The blind spot monitor main switch (combination switch assembly) is on.

      • Vehicle speed is more than approximately 16 km/h (10 mph).

   2. Conditions in which a sensor can detect a vehicle

      The blind spot monitor function indicates detection of a vehicle in the detection area when either condition is met:

      
      

      • When a vehicle is detected in an adjacent lane overtaking this vehicle.

      • When a vehicle is detected entering the detection area because it changed lanes.

   3. 

      *a	Vehicles in the following areas can be detected:
      *b	Within approximately 3.5 m (11.49 ft.) from the side of the vehicle
      *c	Within approximately 3 m (9.85 ft.) behind the rear bumper
      *d	Within approximately 1 m (3.29 ft.) forward of the rear bumper

      Detection area

      Vehicles in the following areas can be detected:

2. Operation description of the RCTA function (w/ RCTA)

   
   

   1. Operation conditions:

      
      

      • The blind spot monitor main switch (combination switch assembly) is on.

      • The shift lever is in R.

      • The vehicle speed is less than approximately 8 km/h (5 mph).

   2. Conditions in which a sensor can detect a vehicle

      The RCTA function indicates detection of a vehicle in the detection area when both conditions are met:

      
      

      • A vehicle is approaching this vehicle from diagonally behind.

      • The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (17 mph).

   3. 

      *a	Vehicles in the following areas can be detected:
      *b	Within approximately 5.5 to 20 m (18.04 to 65.62 ft.) from the side of the vehicle (detection area changes according to vehicle speed)
      *c	Within approximately 6 m (19.69 ft.) behind the rear bumper

      Detection area

      Vehicles in the following areas can be detected:

OPERATION OF OUTER REAR VIEW MIRROR INDICATOR (w/o RCTA)

OPERATION OF OUTER REAR VIEW MIRROR INDICATOR AND REAR CROSS TRAFFIC ALERT BUZZER (BLIND SPOT MONITOR BUZZER) (w/ RCTA)
