Outline<\/p>\n

\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) system is designed to apply the brakes automatically to reduce the damage from a possible collision with vehicles crossing from rear side of the vehicle when the vehicle is reversing to get out of the parking lot.<\/div>\n
\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 Tires for all four wheels must always be of the specified type and size. If tires other than the specified type and size are used, the Smart Brake Support [Rear Crossing] (SBS-RC) may not operate normally.<\/div>\n
\u2022 Do not mix tire types or use tires with significantly different wear patterns on the same vehicle. Use of inappropriate tires could result in the DSC and Smart Brake Support [Rear Crossing] (SBS-RC) not operating normally.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) is designed only to assist the driver. Even if the Smart Brake Support [Rear Crossing] (SBS-RC) is operating, the driver’s operation is given priority. Therefore, if the driver operates the brake to avoid a possible collision, the Smart Brake Support [Rear Crossing] (SBS-RC) is canceled.<\/div>\n
\u2022 To prevent a mistaken operation of the Smart Brake Support [Rear Crossing] (SBS-RC) system when performing a vehicle inspection on a chassis dynamometer, turn off the Smart Brake Support [Rear Crossing] (SBS-RC) system using the i-ACTIVSENSE switch .<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n



\n<\/a><\/p>\n

CONSTRUCTION<\/p>\n

\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) uses rear side radar sensor and rear mount camera located in the rear bumper.<\/div>\n
\u2022 The rear side radar sensors and the rear mount camera installed on the rear bumper detect vehicles crossing from rear side of the vehicle.<\/p>\n\n\n\n

Functions<\/p>\n


<\/p>\n

<\/a><\/p>\n

Brake control<\/p>\n

\n
\n
\u2022 When the body control module (BCM) determines that there is the possibility of a collision with a vehicle or obstruction at the rear, it send a brake prefill request signal to the DSC HU\/CM based on the object information from the parking assist unit (rear side ultrasonic sensors) and 360\u00b0 view monitor control module\/parking assist unit (optical). Then, if the driver does not perform an avoidance maneuver and the possibility of a collision has increased, the body control module (BCM) send a brake control request signal to the DSC HU\/CM to perform the brake control.<\/div>\n
\n
\n
\u2015 Brake prefill<\/div>\n
\n
\n
\u2022 If the body control module (BCM) determines that there is the possibility of a collision with a vehicle crossing from rear side of the vehicle while reversing, the DSC HU\/CM performs brake prefill, pressurizes the brake fluid to eliminate the play between the brake pads and disc plates. As a result, immediate braking force is available when the driver notices a condition at the rear of the vehicle and depresses the brake pedel.<\/div>\n<\/dd>\n<\/dl>\n
\u2015 Brake control<\/div>\n
\n
\n
\u2022 If the body control module (BCM) detects the vehicle may be in danger of a collision with a vehicle while reversing, the DSC HU\/CM automatically operates the brake control on all four wheels and, at the same time, a warning sound (Smart Brake Support [Rear Crossing] (SBS-RC)) is activated and the warning screens are indicated on the multi-information display and the active driving display to warn the driver.<\/div>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n<\/dd>\n<\/dl>\n
\n
\n
Warning<\/div>\n<\/dd>\n
\n
\n
\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) operates automatically when certain conditions are met, however it is not a system which guarantees collision prevention under all conditions.<\/div>\n
\u2022 The brake control has limitations. Always verify the safety of the surrounding area and depress the brake pedal while keeping a safe distance from vehicles or obstructions at the rear of the vehicle.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n

SMART BRAKE SUPPORT [REAR CROSSING] (SBS-RC) DISPLAY FUNCTION<\/p>\n

\n
\n
\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) system notifies the driver of the system conditions using the Smart Brake Support (SBS) OFF indicator light, multi-information display and the active driving display .<\/div>\n<\/dd>\n<\/dl>\n

Note<\/div>\n<\/dd>\n
\n
\n
\u2022 The Smart Brake Support [Rear Crossing] (SBS-RC) system will operate even if the DSC OFF indicator light is turned on after the DSC operation is inhibited by operating the DSC OFF switch. If the Smart Brake Support [Rear Crossing] (SBS-RC) system operates while the DSC is inhibited, the DSC becomes operational and the DSC OFF indicator light turns off.<\/div>\n
\u2022 The rear side radar sensors or rear mount camera may not detect normally if ice, snow or dirt is adhering to them. Due to this the Smart Brake Support [Rear Crossing] (SBS-RC) may not operate normally.<\/div>\n
\u2022 The rear side radar sensors or rear mount camera may not detect normally depending on the road surface or vehicle conditions. Due to this the Smart Brake Support [Rear Crossing] (SBS-RC) may not operate normally.<\/div>\n
\u2022 Depending on the obstruction, the rear side radar sensors or rear mount camera may not detect it. Due to this, the Smart Brake Support [Rear Crossing] (SBS-RC) may not operate normally.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n

\u2022 If the rear side radar sensors and 360\u00b0 view monitor control module\/parking assist unit (optical) detects a vehicle or an obstruction, it sends an object information (1) to the body control module (BCM).<\/div>\n
\u2022 If the body control module (BCM) receives an object information (1) and determines that there is the possibility of a collision with a vehicle crossing from rear side of the vehicle while reversing, it sends a brake prefill request signal (2) to the DSC HU\/CM. At the same time, the body control module (BCM) outputs a warning sound signal (2) to the Notification and Warning Speaker (Rear) and the Notification and Warning Speaker (Rear) sounds a warning.<\/div>\n
\u2022 When the DSC HU\/CM receives the brake prefill request signal (2), it activates the pump motor (3). At this time, all of the solenoid valves are off and the brake fluid pressure generated by the pump motor is conducted (4) to the caliper pistons on each wheel.<\/div>\n
\u2022 By conducting the brake fluid pressure generated by the pump motor to the caliper pistons, the clearance between the brake pads and disc plates is maintained in a narrowed condition.<\/div>\n
\u2022 As a result, if the driver becomes aware of a vehicle or obstruction at the rear and depresses the brake pedal or the driver does not perform an avoidance maneuver and the brake control is operated, braking force is generated immediately and the braking distance is reduced.<\/div>\n<\/dd>\n<\/dl>\n\n\n\n

\u2022 After the brake prefill operates, if the driver does not perform an avoidance maneuver, the body control module (BCM) determines that a collision may occur based on an object information (1) and the body control module (BCM) outputs a brake control request signal (2) to the DSC HU\/CM. At the same time, the body control module (BCM) outputs a warning sound signal (2) to the Notification and Warning Speaker (Rear) and the the Notification and Warning Speaker (Rear) sounds a warning.<\/div>\n
\u2022 When the DSC HU\/CM receives the brake control request signal (2), it energizes the linear control solenoid valves to switch the hydraulic pressure circuit and increase the brake fluid pressure. As a result, the brake control is activated (3).<\/div>\n
\u2022 While the brake control is operating, a brake light signal (3) from the DSC HU\/CM is output to the electrical supply unit (ESU) at the same time. When the electrical supply unit (ESU) receives the brake light signal, it turns the brake lights on (4).<\/div>\n
\u2022 An answer signal (5) is output to the DSC HU\/CM from the electrical supply unit (ESU) at the same time the brake lights are illuminated.<\/div>\n
\u2022 While the brake control is operating, a message is displayed in the multi-information display and active driving display *1<\/sup>.<\/div>\n
\u2022 The brake control is maintained in this condition for approx. 2 sec<\/span> after the vehicle is stopped. Thereafter, the driver needs to depress the brake pedal to maintain the vehicle in a stopped condition.<\/div>\n<\/dd>\n<\/dl>\n
