MRR-35 Adaptive Cruise Control System

Product Information: Adaptive Cruise Control System (Front Radar)

The Adaptive Cruise Control System (Front Radar) is a system designed to help drivers maintain a safe following distance while driving. The system uses radar technology to detect the distance between the driver’s vehicle and the vehicle in front of it. The system can automatically adjust the speed of the vehicle to maintain a safe following distance, which reduces the risk of accidents caused by sudden braking or unexpected obstacles on the road.

System Operation

The Adaptive Cruise Control System operates in several modes:

• Normal Mode Control: In this mode, the system maintains a set following distance from the lead vehicle. The driver sets the cruising speed, and the system adjusts the speed as needed to maintain the set distance.
• Stop mode Control: In this mode, the system can automatically start or stop the vehicle when the lead vehicle stops or starts. If the lead vehicle stops for more than 5 minutes, the system will release control.
• Overdrive Control: This mode allows the control time to be adjusted by OEM/Chassis/Function.
• Overtaking Support Control: This mode provides support for overtaking other vehicles on the road.

Specific System Structure

The Adaptive Cruise Control System includes:

• ACC: The Adaptive Cruise Control unit is responsible for monitoring road conditions and controlling the speed of the vehicle.
• Switch: The switch allows the driver to turn the Adaptive Cruise Control system on and off.
• Cluster: The cluster displays information about the status of the Adaptive Cruise Control system, including warning lights and vehicle status indicators.

Product Usage Instructions

To use the Adaptive Cruise Control System, follow these instructions:

1. Ensure that the Adaptive Cruise Control System is turned on using the switch.
2. Adjust the cruising speed to the desired value using the controls provided.
3. When the lead vehicle is detected, the system will automatically maintain a safe following distance. The driver can adjust the following distance as needed.
4. If the lead vehicle stops for less than 3 seconds, the system will automatically start the vehicle when the lead vehicle starts moving again. If the lead vehicle stops for more than 5 minutes, the system will release control.
5. The driver can manually resume control of the vehicle by pressing the accelerator pedal or turning on the resume/set switch.

Important Notices

It is important to note that modifications to the Adaptive Cruise Control System not approved by the manufacturer may void FCC authorization to operate the equipment. Additionally, the system must comply with FCC rules and regulations regarding interference and accept any interference received.

System Information

Introduction
The ACC system operates the convenience feature automatically maintaining the distance by measuring the distance and speed of the lead vehicle with the radar in front of the car. Also, if the lead vehicle is stopped along the rear of the lead vehicle stops, and re-start feature provides at the start with Stop & Go function.

System Operation

• operation principle
• Absence of a lead vehicle
• Existing of a lead vehicle
• Stopping a lead vehicle
• Blinding a lead vehicle
• Cluster display state
• Cruise control at the driver’s setting speed
• Driving the lead vehicle traveling speed maintaining a set following distance When auto stop and starting the lead vehicle within 3 seconds, automatically start. Accelerate to the target speed and then cruise control.

Normal Mode Control

• All of the speed/distance control can perform from 0 to 200 km/h speed range.
• The minimum target speed is 30km/h.
• If the lead vehicle’s speed is from 0 to 30km/h, the proper distance can be expected(or calculated/measured).

Stop mode Control

• When the lead vehicle is stopped, and then the vehicle would stop at a certain distance.
• [HDA not operated / HDA during operated] If the stop duration is within 3 sec. / 30 sec., the vehicle automatically start, or not manually the resume/set switch turn on or the accelerator pedal is pressed. If the stopping maintain more than 5 minutes, the ACC control will be released.

Overdrive Control

• Driver’s accelerator pedal is pressed, the system will give acceleration priority to the judgment of the driver than the system decision. Then, the driver releasing the accelerator pedal, the vehicle speed gradually will going target speed.

Overtaking Support Control

• The driver turn on the left blinker, the system internally set as the target distance automatically-step regardless of the display condition. Therefore, a slight acceleration can help to occur soft overtaking.
• The function can be operated 60kph over.

Specific System Structure

ACC

• Monitoring front road condition(sensing function)
• Driver riding/getting off and monitoring car condition(ECU function)
• Calculating and output of the Required acceleration(ECU function)

Switch

• ACSS system On/Off
• Target speed control
• Target distance control
• Operation ON/OFF
• ACC-CC switching operation

Cluster

• System On/Off
• System Alarm
• ACC Operation State (lead vehicle, Break, Overtake, Stop modes) Display
• ACC Driver Setting State (Target Speed/Distance) Display
• ACC Auto-unlock/ Usage Condition Un-satisfaction
• ACC Hazardous situation (lead vehicle breaking, Stop vehicle alert) Display

Instruction of the ACC control using switch

ON/OFF Main Switch

• ON/OFF function
• In case of the Standby mode, “CRUISE” Ramp turn ON

SET/–  Switch

• At the Stand by mode, Press SET Switch and then Control start.
  • The target speed set 30 km/h when the car speed is from 0 to 30 km/h.
  • When the car speed is over 30 km/h, the target speed is the same as current speed.
• If the SET switch is pressed under control, the target speed will be decreased.
  • Press short period, the speed decrease 1km/h step. ex) 81→80→79→78
  • Press long period, the speed decrease at first 1km/h step then 10km/h step. ex) 77→76→70→60

RES/+ Switch

• At Standby mode, Press RES+ switch and then control start.
  • After the OFF mode changed to Standby mode, the ACC usage history have to be existed at least once.
•  If the RES+ switch is pressed under control, the target speed will be increased.
  •  Press short period, the speed increase 1km/h step. ex) 77→78→79→80→81
  • Press long period, the speed increase at first 1km/h step then 10km/h step. ex) 66→67→70→80

CANCEL Switch

• Released from the control condition

Distance setting switch

• Set the target headway distance(Initial value is level.4)
• Press the switch, the target headway distance value changed in the following order.
  • level.4->level.3->level.2->level.1->level.4
  • In case of the car speed is 90km/h
  • At level 1 (1sec.), Headway distance is 25m.
  • At level 2 (1.3sec.), Headway distance is 32.5m
  •  At level 3 (1.6sec.), Headway distance is 40m
  • At level 4 (2.1sec.), Headway distance is 52.5m
•  If press the switch over 2 sec, the ACC mode is switched the CC mode each other.
