SYSTEM DESCRIPTION GENERAL (a) The blind spot monitor system has a blind spot monitor function and RCTA function.
(1) Blind spot monitor function
- The blind spot monitor function is a function that assists the driver when changing lanes.
This function uses quasi-millimeter wave radar to
detect vehicles that are traveling in adjacent lanes in the areas that
are not visible using the outer rear view mirror assemblies (blind
spots) and vehicles that are approaching rapidly from up to 60 m behind
this vehicle in the areas that are not visible using the outer rear view
mirror assemblies (blind spots).
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
- The RCTA function is a function that informs the driver a vehicle is
approaching from the left or the right at the rear of the vehicle. The
function uses quasi-millimeter wave radar to detect the position and
relative speed of other vehicles. When the function determines that a
vehicle is approaching this vehicle, this function informs the driver
using the outer rear view mirror indicators and blind spot monitor
buzzer.
FUNCTION OF COMPONENTS
Component | Function |
Blind Spot Monitor Sensor |
- Consists of a 24 GHz radar module and an integrated processing module.
- Illuminates or blinks the outer rear view mirror indicator on an outer rear view mirror assembly with cover.
- Sounds the RCTA buzzer (blind spot monitor buzzer) when the RCTA function is operating.
- Changes the outer rear view mirror indicator on an outer rear view
mirror assembly with cover from illuminated to blinking when a turn
signal switch operation signal is received from the combination meter
assembly with the blind spot monitor system operating.
- Dims the outer rear view mirror indicator on the outer rear view mirror assembly with cover.
- Displays the RCTA icon on the multi-display when the RCTA function is operating.
| Outer Rear View Mirror Assembly With Cover
- Outer Mirror (Outer Rear View Mirror Indicator)
| Turns on or blinks the indicator based on a signal from the blind spot monitor sensor. |
Steering Pad Switch Assembly | Enables,
disables or cuts off the operation of the blind spot monitor system by
transmitting switch operation signals to the combination meter assembly. |
RCTA Buzzer (Blind Spot Monitor Buzzer) |
Sounds based on a signal from the blind spot monitor sensor. |
Combination Meter Assembly
- Multi-information Display
|
- Transmits a turn signal switch operation signal from the headlight
dimmer switch assembly to the blind spot monitor sensor via CAN
communication.
- Displays an error message on the multi-information display if the blind
spot monitor sensor detects a malfunction while it is operating.
| Main Body ECU (Multiplex Network Body ECU) |
Transmits the destination information and the dimmer signal to the blind spot monitor sensors via CAN communication. |
Skid Control ECU | Transmits a vehicle speed signal to the blind spot monitor sensors via CAN communication. |
ECM | Transmits a shift position signal (R) to the blind spot monitor sensors via CAN communication. |
Steering Sensor | Detects
the angle of the steering wheel and transmits the resulting signals to
the blind spot monitor sensors via CAN communication. |
Airbag Sensor Assembly
- Yaw Rate and Acceleration Sensor
| Transmits the yaw rate signal to the blind spot monitor sensor via CAN communication. |
- Television Camera Assembly*1
- Parking Assist ECU*2
| Receives
the blind spot monitor sensor information via CAN communication and
sends it to the multi-display through the video signal cable. |
Radio and Display Receiver Assembly |
- Receives the video signals from the television camera assembly and displays the RCTA icon on the display panel.*1
- Receives the video signals from the parking assist ECU and displays the RCTA icon on the display panel.*2

OPERATION DESCRIPTION (a) Operation description of the blind spot monitor system
(1) Operation conditions:
- The blind spot monitor system is on.
- The shift lever is in any position other than R.
- 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 system 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) Detection area Vehicles in the following areas can be detected:
*a | Within Approx. 3.5 m (11.48 ft) from Side of Vehicle |
*b | Within Approx. 3 m (9.84 ft) behind Rear Bumper |
*c | Within Approx. 1 m (3.28 ft) forward of Rear Bumper |
|
Detection Area | (b) Operation description of the RCTA function
(1) Operation conditions:
- The RCTA function 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 from the right or left at the rear of the vehicle.
- The vehicle speed is approximately 8 km/h (5 mph) to 28 km/h (18 mph).
(3) Detection area Vehicles in the following areas can be detected:
*a | Within Approx. 5.5 to 20 m (18.05 to 65.62 ft) from Side of Vehicle (detection area changes according to vehicle speed) |
*b | Within Approx. 6 m (19.69 ft) behind Rear Bumper |
|
Detection Area | OPERATION OF OUTER REAR VIEW MIRROR INDICATOR AND RCTA BUZZER (BLIND SPOT MONITOR BUZZER)
(a) Initial check (1)
When the blind spot monitor system is turned on with the engine switch
on (IG), the outer rear view mirror indicators on the outer rear view
mirror assembly with cover illuminate for 3 seconds. (2)
When the RCTA function is turned on with the engine switch on (IG), the
outer rear view mirror indicators on the outer rear view mirror
assembly with cover illuminate for 3 seconds and the RCTA buzzer (blind
spot monitor buzzer) sounds for 1 second. (3) When
the engine switch is turned from off to ON with the blind spot monitor
system on, the outer rear view mirror indicators on the outer rear view
mirror assembly with cover illuminate for 3 seconds. (b) Operation for each function
(1) Operation for blind spot monitor system
- When a sensor detects a vehicle in the blind spot area, the outer rear
view mirror indicator on the outer rear view mirror assembly with cover
illuminates.
- If the turn signal switch is operated while the sensor is detecting a
vehicle in the detection area and the outer rear view mirror indicator
on the outer rear view mirror assembly with cover is illuminated, the
indicator starts blinking as shown in the illustration.
(2) Operation for RCTA function
- When all of the operation conditions for the RCTA function are met, the
outer rear view mirror indicators on the outer rear view mirror assembly
with cover blink for 2.5 seconds and the RCTA buzzer (blind spot
monitor buzzer) sounds for 2.3 seconds as shown in the illustration.
*a | 0.125 Seconds |
*b | 2.5 Seconds |
*c | 0.1 Seconds |
*d | 0.4 Seconds |
*e | 2.3 Seconds |
