EXAMPLE

OPERATION DESCRIPTION

• The TSR system is controlled by the front camera unit.
• The front camera unit turns on the TSR system when the turned ON by combination meter.
• The front camera unit detects the road sign.
• The front camera unit transmits the meter display signal to the combination meter, when detecting the road

sign.

• The front camera unit receives the speed limit information data from the NAVI control unit. (With navigation

system)

• The front camera unit detects speed limit signs, recognizes speed limit signs by combining the detected

speed limit signs with speed limit information data received from the NAVI control unit, and transmits a meter
display signal to the combination meter. (With navigation system)

• The front camera unit adjusts the detection range of road signs according to a steering angle sensor signal

received from the steering angle sensor.

Operation Condition

• TSR: ON
NOTE:
• TSR system ON/OFF can be set on the combination meter
• The TSR system may not function properly, depending on the situation. Refer to

SYSTEM DIAGRAM

AROUND VIEW MONITOR CONTROL UNIT INPUT/OUTPUT SIGNAL ITEM

Input Signal Item

Output Signal Item

FUNCTION DESCRIPTION

• Operates when the vehicle speed is 60 km/h or higher.
• Detects the steering status and judges the attentiveness of the driver. The driver's attentiveness is shown on

the vehicle information display in eight stages (level indicator).

• When it is judged from the degree of minor swerving in the steering operation that the vehicle is drifting, the

driver is prompted to exert caution by the drift warning, which displays on the combination meter, and by a
buzzer sound.

• When the engine is stopped, the system is reset.
• When the level indicator on the drift warning display becomes 1, the system warns the driver with a buzzer

sound.

OPERATION DESCRIPTION

• The DAA (Driver Attention Alert) is controlled by the around view monitor control unit.
• ON/OFF of the DAA is performed by using the combination meter.
• The steering angle sensor detects the degree of swerving in the steering operation.
• When the around view monitor control unit judges that the steering operation is drifting (when the level indi-

cator in the drift warning display becomes 1), the following control is performed and the driver is warned.

- Transmits the buzzer output signal to the combination meter and sounds the buzzer.
