DISTANCE RECOGNITION SUPPORT SYSTEM (DRSS)
id921000000400
Purpose of Adoption
• The DRSS emits radio waves from the radar to recognize the distance and speed of a vehicle ahead and displays the distance from the vehicle ahead in steps.
Service point
• Radar is emitted from the radar set in the front of the vehicle to detect vehicles and obstructions ahead and perform control.
• If the radar or vehicle control module (V/C-Module) is replaced, always perform the aiming procedure. Auto aiming adjustment is only in the up/down directions. Left/right direction aiming is required.
• When air bags are replaced, it is necessary to perform the yaw rate 0-point command for the vehicle control module (V/C-Module). (For details, refer to the workshop manual)
Common Inquiry
• In the following cases, determination of a vehicle ahead may be delayed or it may not be possible to correctly display the distance between vehicles.
-
1. Weather conditions
-
― Heavy rain, snow, blizzard, heavy fog
2. Road conditions
-
― Road conditions (slope), curves
3. Detection target
-
― Low vehicles, small vehicles, round vehicles, vehicles with material that reflects radio waves poorly (canvas, hard plastic liftgate, empty trailer), vehicle ahead throws water/snow/sand from tires into the air, vehicles in radar blind spot.
4. Detecting vehicle conditions Load condition, frost on protective cover (Radome), looseness in sensor installation area, scratching/soiling on protective cover (Radome)
5. Other
-
― If a vehicle cuts into driving lane suddenly directly after turning on turn signal
Other
• The system on/off and the DRSS elert indication sensitivity level can be changed by instrument cluster personalization.
• Sensor type:
