Operation Manual Adaptive Cruise Control System (Front Radar) 07, 2022 1 1. System Information 1. 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. 2. 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 drivers 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. 1) 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 vehicles speed is from 0 to 30km/h, the proper distance can be expected(or calculated/measured). 2) 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. 3) Overdrive Control The control time be adjustable by OEM/Chassis/Function. 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. 4) 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. 2 2. Specific System Structure 1.

Specific System Structure 4. Instruction of the ACC control using switch 1) ON/OFF Main Switch ON/OFF function In case of the Standby mode, CRUISE Ramp turn ON 2) 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) 81807978 Press long period, the speed decrease at first 1km/h step then 10km/h step. ex) 77767060 3) 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) 7778798081 Press long period, the speed increase at first 1km/h step then 10km/h step. ex) 66677080 4) CANCEL Switch Released from the control condition 5) 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. 4 2.
