Cross Traffic Monitor System Description
The BSI radar unit emits radar waves from the left and right BSI radar and detects other vehicles in the blind spot. Cross traffic monitor system function uses the BSI radar unit.
The cross traffic monitor system alerting arrows are displayed on the rearview camera image of the audio-navigation display (or center display unit) when the vehicle is in reverse. When an approaching vehicle enters the cross traffic monitor system alert zone, the cross traffic monitor system warns the driver with a warning indicator and an audible alarm.
If the BSI radar unit malfunctions, the cross traffic monitor system stops operating. The vehicle alerts the driver that there is a problem by turning on the BSI indicator on the gauge control module, and the cross traffic monitor system indicator is shown in rearview camera image of the center display unit, when shift the transmission to R position/mode.
Radar Zone Definition
The BSI radars are installed on the left and right sides of the rear side outer panel and covered by the bumper. The mounting positions are symmetrical on the left and the right.
When the BSI radar has a clear view of the environment around it, the cross traffic monitor system will warn of detected approaching vehicles.
The cross traffic monitor system evaluates the approaching target's speed, time to potential collision and location in the cross traffic monitor system's alert zone to decide if the system should warn or not warn the driver.
Detection Conditions
| Parameter | Warn |
|---|---|
| Your vehicle speed | Less than 3 mph (5 km/h) |
| Time to collision | 1.2 to 3.2 seconds |
| Target closing speed | More than 6 mph (10 km/h), 16 mph (25 km/h) or less |
| Detection range | More than 3.3 m (10.8 ft) (example: Target vehicle speed 6 mph (10 km/h) and time to collision is estimated as 1.2 seconds) |
The system defines the time to collision, measured in seconds, that it takes for the target vehicle traveling at its current speed to reach line L when the target vehicle is approaching perpendicular (between line A and B) to the your vehicle. If the target vehicle is approaching from a wider angle (between line B and C), the time to collision is measured by how long it takes the target vehicle traveling at its current speed to reach point B.
Detection range
Cross Traffic Monitor System
When driving in reverse, the BSI radar unit monitors vehicles approaching from behind your vehicle. When detecting a vehicle approaching from behind, the unit sends the information to the center display unit via B-CAN line. When receiving the information, the center display unit gives the warning to the driver by displaying "<<" (a warning arrow) on the center display unit rearview camera image. An audible alarm is generated by the gauge control module. The warning indicates left, right or both. The cross traffic monitor system gives a warning depending on the position, speed of the target vehicle in the detection range and the time remaining to the collision.
| Restriction Factors | Warning Conditions |
|---|---|
| Your Vehicle Speed | Less than 3 mph (5 km/h) |
| Remaining Time to Collision | More than 1.2 seconds to less than 3.2 seconds |
| Target Vehicle Speed | More than 6 mph (10 km/h) and less than 16 mph (25 km/h) |
| Distance to Target Vehicle | Less than 8.3 m (27.2 ft) or based on time to collision (up to 25 m (82 ft)) |
