The BCI systems can help alert the driver of approaching vehicles or rear objects when the driver is backing out of a parking space.

The BCI systems can help alert the driver of approaching vehicles or rear objects when the driver is backing out of a parking space.

When the shift position is R (Reverse) and the vehicle speed is less than approximately 5 MPH (8 km/h), the BCI system operates.

The BCI system uses radar sensors 1 installed on both sides near the rear bumper to detect an approaching vehicles and sonar sensors to detect objects in the rear.

The BCI system uses radar sensors 1 installed on both sides near the rear bumper to detect an approaching vehicles and sonar sensors to detect objects in the rear.

The radar sensors 1 detects the approaching vehicle from up to approximately 15 m (49 ft.) away. The sonar sensors 2 and 3 detect a rear obstacle at up to approximately 4.9 feet (1.5 m).

If the radar detects a vehicle approaching from the side or the sonar detects close objects in the rear, the system gives visual and audible warnings, and applies the brake for a moment when the vehicle is moving backwards. After the automatic brake application, the driver must depress the brake pedal to maintain brake pressure. If the drivers foot is on the accelerator pedal, the system pushes the accelerator upward before applying the brake. If you continue to press the accelerator, the system will not engage the brake.
