SMART BRAKE SUPPORT (SBS)
id921000000200
Purpose of Adoption
• If a collision is predicted, collision damage is mediated. Operates at speeds of 15 km/h to 145 km/h.
• (Europe only) Operates at 15 km/h to 200 km/h, warning functions for a moving vehicle only.
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 SBS control unit 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 SBS control unit.
• Collision damage is mediated by the following steps.
• Step 1: If a collision is predicted, the driver is notified by a warning sound. At the same time, the brake assist force is increased. (Strong braking occurs by the driver only lightly depressing the brakes)
• Step 2: If it is determined that a collision is unavoidable, a signal is output to the DSC and the brakes are applied to mediate the collision. (However, if SCBS is equipped, the SCBS takes priority with the speed at 30 km/h or less. In this case, a collision is avoided)
Common Inquiry
• Under the following conditions, system non-operation may occur or it may not be possible to obtain sufficient effect.
-
1. Weather conditions
Heavy rain, snow, blizzard, heavy fog
2. Road conditions
Road grade (slope) curves, narrow roads, poor roads
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, other than 4-wheel vehicles (2-wheel vehicles, pedestrians, standing trees, pylons) on-coming vehicles, vehicles in radar blind spot.
4. Detecting vehicle conditions
Load condition, frost on protective cover (Radome), tire puncture, or low tire pressure, looseness in sensor installation area, scratching/soiling on protective cover (Radome)
5. Other
Vehicle suddenly cuts into driving lane, distance between vehicles is extremely short, battery voltage decrease
• Under the following conditions, the system could operate by mistake.
-
1. Road conditions
Road grade (slope), curves, tunnels, iron bridges, gates, entrance to underground parking area, poor roads, object projects from road surface (manhole, cat-eye, rail tracks), grass foliage
2. Detection target
Other than 4-wheeled vehicles (2-wheeled vehicles, pedestrians, standing trees, pylons), on-coming vehicles
3. Detecting vehicle conditions
Load condition, looseness in sensor installation area
4. Other
Low battery voltage, vehicle ahead is rapidly approached
Other
• Radar is emitted from the radar set in the front of the vehicle and vehicles and obstructions ahead are detected, however, the radar reflected from the target may be weak and go undetected, or the target may not be in the radar emitting area, and thus the system may determine that there is no vehicle or obstruction ahead.
• The system on/off and the SBS warning/brake operation sensitivity level can be changed by instrument cluster personalization.
• (Europe only) Operation sensitivity cannot be changed.
• Sensor type: Radar sensor
