Purpose<\/p>\n

\u2022 The Smart Brake Support [Rear] (SBS-R) system is designed to apply the brakes automatically to reduce the damage from a possible collision if the driver fails to confirm the safety at the rear while reversing resulting in an increased possibility of a collision with vehicles or obstructions at the rear of the vehicle.<\/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] (SBS-R) system 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] (SBS-R) system 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] (SBS-R) system is designed only to assist the driver. The driver’s driving operation always takes priority even while the Smart Brake Support [Rear] (SBS-R) system is operating. For this reason, if the driver operates the brakes to avoid danger, the Smart Brake Support [Rear] (SBS-R) system operation is canceled.<\/div>\n
\u2022 In the following cases, turn off the Smart Brake Support [Rear] (SBS-R) system using the center display or i-ACTIVSENSE switch to prevent a mistaken operation of the Smart Brake Support [Rear] (SBS-R) system.<\/div>\n
\n
\n
\u2015 The vehicle is on a chassis roller.<\/div>\n
\u2015 The vehicle is being towed or when towing another vehicle.<\/div>\n
\u2015 When driving on rough roads such as in areas of dense grass or off-road.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n<\/dd>\n<\/dl>\n



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

Structural View<\/p>\n

\u2022 The Smart Brake Support [Rear] (SBS-R) uses rear side ultrasonic sensors and rear mount camera located in the center of the rear bumper.<\/div>\n
\u2022 The rear side ultrasonic sensors and rear mount camera installed on the rear bumper detect vehicles and obstructions at the rear of the vehicle.<\/div>\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 a possible collision with a vehicle or obstruction at the rear has increased, it send a brake prefill request signal to the DSC HU\/CM based on the object information from the parking assist unit (ultrasonic) and 360\u00b0 view monitor control module\/parking assist unit (optical). Then, if the driver does not perform an avoidance maneuver and there is the possibility of a collision, 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 control<\/div>\n
\n
\n
\u2022 If the body control module (BCM) detects the vehicle may be in danger of a collision with an obstruction or 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] (SBS-R)) 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

\u2022 If the parking assist unit (ultrasonic) and the 360\u00b0 view monitor control module\/parking assist unit (optical) detects that the vehicle is approaching a vehicle or an obstruction while reversing, the object information (1) is sent to the body control module (BCM).<\/div>\n
\u2022 If the body control module (BCM) receives the object information (1), it sends the brake prefill request signal (2) to the DSC HU\/CM.<\/div>\n
\u2022 When the DSC HU\/CM receives the brake prefill request sigal, 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, and the body control module (BCM) determines that a collision may occur, the body control module (BCM) sends a brake control request signal (1) to the DSC HU\/CM.<\/div>\n
\u2022 When the DSC HU\/CM receives the brake contro request signal, it energizes the linear control solenoid valve to switch the hydraulic pressure circuit and increases the brake fluid pressure. As a result, the brake control is activated (2).<\/div>\n
\u2022 While the brake control is operating, the DSC HU\/CM sends a brake light signal (2) 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 (3).<\/div>\n
\u2022 The electrical supply unit (ESU) outputs the brake light condition signal (3) to the DSC HU\/CM 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.<\/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\n\n\n
