Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)

The Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function) uses the front radar sensor and the forward sensing camera (FSC) to detect a vehicle ahead, and it performs headway control to maintain a constant distance from a vehicle ahead without the driver having to depress the accelerator or brake pedal. Additionally, the detecting vehicle stops when the vehicle ahead stops, and headway control resumes by operating the RES switch/accelerator pedal after the vehicle ahead moves again. This reduces the strain of operating the vehicle such as during long-distance driving, driving at high speeds, and while in heavy traffic. If the detecting vehicle suddenly approaches the vehicle ahead too closely such as when the vehicle ahead is braking suddenly, the system alerts the driver using a warning sound and warning indication.

(See MAZDA RADAR CRUISE CONTROL WITH STOP & GO FUNCTION (MRCC WITH STOP & GO FUNCTION).)

Cruising & traffic support (CTS)

The cruising & traffic support (CTS) is a system to reduce driving fatigue during long drives on expressways and it consists of the headway control function and the steering assist function. Using the headway control function allows the driver to maintain constant-speed driving at a set vehicle speed and to maintain a constant distance from a vehicle ahead without having to depress the accelerator or brake pedal. If the detecting vehicle stops when the vehicle ahead stops, headway control resumes after the vehicle ahead moves again. If the detecting vehicle approaches the vehicle ahead too closely while in headway control, the driver is alerted using a warning sound and warning indication. Furthermore, when the steering assist function detects vehicle lane lines, it assists in keeping the vehicle in the driving lane. When the steering assist function does not detect vehicle lane lines, it assists in driving along the trajectory of the vehicle ahead.

(See CRUISING & TRAFFIC SUPPORT (CTS) [(E)].)

Distance & speed alert (DSA)

For the distance & speed alert (DSA), the body control module (BCM) calculates the distance between the vehicle ahead and the detecting vehicle based on target information from the front radar sensors and the forward sensing camera (FSC), and it alerts the driver or displays warning indications about approaching the vehicle ahead on the active driving display or multi-information display.

(See DISTANCE & SPEED ALERT (DSA).)

Lane-keep assist system

The lane-keep assist system detects the white lines (yellow lines) of the vehicle lane using the forward sensing camera (FSC) installed to the windshield, and alerts the driver that the vehicle may be deviating from its lane and it provides steering assistance to help the driver stay within the vehicle lane.

(See LANE-KEEP ASSIST SYSTEM [(E)].)

Lane departure warning system (LDWS)

The lane departure warning system (LDWS) recognizes vehicle lane lines on a road using the forward sensing camera (FSC) installed to the windshield, and if the vehicle departs from its lane unbeknownst to the driver, the system alerts the driver of the lane departure using a warning indication and warning sound.

(See LANE DEPARTURE WARNING SYSTEM (LDWS) [(E)].)

Emergency lane keeping [road keep assist]

The system helps in avoiding departure from the road by providing steering assistance if the vehicle may be deviating from the road.

(See EMERGENCY LANE KEEPING [ROAD KEEP ASSIST] [(E)].)

Emergency lane keeping [blind spot assist]

If there is the possibility of a collision with a vehicle in an adjacent lane, the system provides steering assistance to avoid a departure from the driving lane.

(See EMERGENCY LANE KEEPING [BLIND SPOT ASSIST] [(E)].)

Adaptive LED headlights

The adaptive LED headlights improve visibility by changing the headlight illumination range depending on the vehicle driving conditions and the surrounding conditions without switching the headlights between HI/LO.

(See ADAPTIVE LED HEADLIGHTS [(E)].)

High beam control (HBC)

The high beam control (HVC) system performs automatic switching to low beams only when the forward sensing camera (FSC) installed to the windshield recognizes an on-coming vehicle, a vehicle ahead or when traveling through towns and cities to prevent blinding of other vehicles from headlight glare, and to assure visibility of drivers.

(See HIGH BEAM CONTROL (HBC) SYSTEM [(E)].)

Blind spot monitoring (BSM) system

The blind spot monitoring (BSM) system detects vehicles approaching from behind using the rear side radar sensors and alerts the driver of the presence of an approaching vehicle. In addition, if the turn switch is operated when a vehicle is approaching from behind, it warns the driver by operating the warnings.

(See BLIND SPOT MONITORING (BSM) SYSTEM.)

Front cross traffic alert system

The front cross traffic alert system alerts the driver of vehicles approaching in areas with poor visibility such as at intersections when the vehicle accelerates from a standstill.

(See FRONT CROSS TRAFFIC ALERT (FCTA) SYSTEM.)

Rear cross traffic alert system

The rear cross traffic alert system alerts the driver of approaching vehicles when the vehicle is reversing.

(See REAR CROSS TRAFFIC ALERT (RCTA) SYSTEM.)

Driver attention alert system

The driver attention alert system warns the driver using the warning display and sound if it detects the driver's lack of attentiveness.

(See DRIVER ATTENTION ALERT SYSTEM.)

Driver monitoring (DM)

The driver monitoring (DM) warns the driver using the warning display and sound if it detects the driver's lack of attentiveness.

(See DRIVER MONITORING (DM).)

Traffic sign recognition system (TSR)

The traffic sign recognition system (TSR) provides support for safe driving by displaying traffic signs on the active driving display and the instrument cluster or by notifying the driver of excessive speed.

(See TRAFFIC SIGN RECOGNITION SYSTEM (TSR) [(E)].)

With 360° view monitor system

The 360° view monitor system is a safety system supporting the driver in all directions to prevent accidents by reducing the driver's blind spots.

(See 360°VIEW MONITOR SYSTEM.)

Intelligent Speed Assistance (ISA)

The Intelligent Speed Assistance (ISA) is a function which keeps the vehicle speed below the speed limit set from a speed limit sign or an optionally set speed limit. If the vehicle speed exceeds the set speed limit while driving on steep slopes, the system notifies the driver using the display and a warning sound.

(See INTELLIGENT SPEED ASSISTANCE (ISA) [(E)].)

Pre-crash safety technology

• The pre-crash safety technology is designed to assist the driver in averting collisions or reducing their severity in situations where they cannot be avoided.

• The pre-crash safety technology has adopted the following systems.

System

Outline

Reference

Smart brake support (SBS) [forward detection]

• The smart brake support (SBS) system detects vehicles ahead, pedestrians, or bicycles using the front radar sensors and the forward sensing camera (FSC) , and if it determines that there is the possibility of a collision, it alerts the driver using warning indications on the active driving display and the multi-information display, and a warning sound.

• If the possibility of a collision increases, brake control is performed to reduce the damage in the event of a collision.

(See SMART BRAKE SUPPORT (SBS) [FORWARD DETECTION].)

Smart brake support (SBS) [turn-across traffic]

If the possibility of a collision with a vehicle approaching in the opposite direction increases due to the driver not confirming the safety while turning at an intersection, the smart brake support (SBS) [turn-across traffic] performs brake control to reduce the damage in the event of a collision.

(See SMART BRAKE SUPPORT (SBS) [TURN-ACROSS TRAFFIC].)

Smart brake support (SBS) [rearward detection]]

If the possibility of a collision with obstructions at the vehicle rear increases due to the driver not confirming the safety while reversing, the smart brake support (SBS) [rearward detection] performs brake control to reduce the damage in the event of a collision.

(See SMART BRAKE SUPPORT (SBS) [REARWARD DETECTION].)

Smart brake support [rear crossing]

If the possibility of a collision with a vehicle at the vehicle rear increases due to the driver not confirming the safety while reversing, the smart brake support (SBS) [rear crossing] performs brake control to reduce the damage in the event of a collision.

(See SMART BRAKE SUPPORT (SBS) [REAR CROSSING].)
