Blind Spot Information System/Cross Traffic Monitor System Description - Overview (2016 2017 2018 2019 2020)
The Blind Spot Information (BSI) radar unit emits radar waves from the left and right BSI radar and detects other vehicles in the blind spot. BSI and Cross Traffic Monitor (CTM) system functions both use the BSI radar unit. BSI lights and the BSI alert indicator warn the driver when a vehicle enters the driver's side or the passenger's side blind spot alert zone. If the driver turns on the turn signal while the BSI alert is on, the BSI alert flashes and an audible alarm sounds to warn the driver.
The CTM system displays the rear camera image on the audio-navigation display when the vehicle is in reverse. When an approaching vehicle enters the blind spot alert zone, the CTM warns the driver with a warning indicator and an audible alarm.
If the BSI radar unit malfunctions, the BSI and CTM systems stop operating. The vehicle alerts the driver that there is a problem by turning on a warning indicator on the gauge control module.
Radar Zone Definition
The BSI radar and BSI radar unit are integrated into one component which are installed on the left and right sides of the rear frame and covered by the bumper. The mounting positions are symmetrical on the left and the right.
BSI System
The radar wave emission range and the vehicle detection range of the BSI radar unit are shown. They are symmetrical. The alert zone makes up only a part of the radar detection range.
CTM System
When the BSI radar has a clear view of the environment around it, the CTM will warn of any approaching hazards.
The CTM system evaluates the approaching target's speed, current location, time to potential collision and location in CTM system's alert zone to decide if the system should warn or not warn the driver.
| Parameter | Warn |
|---|---|
| Your vehicle speed | More 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 | Less than 8.3 m (27.2 ft) |
The system defines the time to collision, measured in seconds, that it takes for the target vehicle traveling at its current speed to reach the line L when the target vehicle is approaching perpendicular (between line A and B) to the client's 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.
