ADAS

Description

When an ADAS or DMS warning is triggered, HOWEN DMS+ADAS SYS directly uploads the pictures or videos of the risky moments to the cloud via the system’s 4G network. Lowering the traffic accidents rate, the company is able to deeply analyze the driver’s driving behavior based on the warning data collected, improving the fleet’s operation efficiency, lowering insurance company’s claim rate, and taking away some of the concerns of the government departments.
Applicable Industries: truck, dump truck, bus, school bus, taxi, e-hailing service, etc.

Functions
1. Forward Collision Warning (FCW)
The system checks the distance between the vehicle in front real-time, and it calculates the potential collision time based on two vehicles relative speeds. The alarm will be triggered when the potential collision time is less than the threshold value.
Alarm sound
Four continuous treble-tone sounds.
Alarm threshold
Turn-on threshold: By default, the function is on when the vehicle speed is
over 30km/h.
Alarm precision
Allowing a 5% miss rate can help achieve an accuracy rate for warnings of
higher than 98%.
Invalidation
When the backlight is too strong, the system will be ineffective temporarily.
During heavy rain and foggy days, the system will be ineffective due to low
scenario
visibility.
2. Headway Monitoring Warning (HMW)
Based on your vehicle’s speed, the system checks the distance with the vehicle in front real-time, and it estimates the collision time if the front vehicle brakes suddenly. The alarm will be triggered when the collision time is less than the threshold value.
Alarm sound
An alto-tone sound every 0.5 second.
Alarm threshold
Turn-on threshold: The function is on when the vehicle speed is over 30km/h.
Detection

Allowing a 1% miss rate can help achieve an accuracy rate for warnings of
precision
higher than 99%.
Invalidation
When the backlight is too strong, the system will be ineffective temporarily.
During heavy rain and foggy days, the system will be ineffective due to low
scenario
visibility.
3. Lane Departure Warning (LDW)
The real-time system detects the lanes to the right and left. The alarm will be triggered when the system detects an unconscious lane deviation based on right and left turn signals.

4 Alarm sound
A series of continuous short sounds.
Alarm threshold
Turn-on threshold: By default, the function is on when the vehicle speed is
over 50km/h.
Alarm precision
Allowing a 5% miss rate can help achieve an accuracy rate for warnings of
higher than 99%.
Invalidation
When the backlight is too strong, the system will be ineffective temporarily.
During heavy rain and fog days, the system will be ineffective due to low
scenario
visibility.
4. Closed-eyes detection
The alarm will be triggered when the system detects the driver has closed his eyes over the threshold time length.
Alarm sound
Voice warning, “Eyes closing too long.”
Alarm threshold
Turn-on threshold: By default, the function is on when the vehicle speed is
over 10km/h.
Invalidation
The system fails to detect highly-reflective sunglasses; normal sunglasses are
scenario
fine.
5. Yawning detection
The alarm will be triggered when the system detects the driver has yawned over the threshold time length.
Alarm sound
Voice warning, “Yawning.”
Alarm threshold
Turn-on threshold: By default, the function is on when the vehicle speed is
over 10km/h.
Alarm precision
Allowing a 5% miss rate can help achieve an accuracy rate for warnings of
higher than 98%.
6. Smoking detection
The alarm will be triggered when the system detects the driver is smoking.
Alarm sound
Voice warning, “No smoking.”
Alarm threshold

Turn-on threshold: The function is on when the vehicle speed is over 10km/h.
Alarm precision

Allowing a 10% miss rate can help achieve an accuracy rate for warnings of
higher than 90%.
7. Calling detection
The alarm will be triggered when the system detects the driver holds a cell phone next to his/her ear while driving.
Alarm sound
Voice warning, “No phone call.”
Alarm threshold

Turn-on threshold: The function is on when the vehicle speed is over 10km/h.
Alarm precision

Allowing a 5% miss rate can help achieve an accuracy rate for warnings of
higher than 98%.
8. Water drinking detection
The alarm will be triggered when the system detects the driver is drinking water. The system can detect various containers such as cups, disposable cups, thermal cups, mineral water bottles, and more.
Howen Technologies Co., Ltd.
5. Alarm sound
Voice warning, “Water drinking.”
Alarm threshold

Turn-on threshold: The function is on when the vehicle speed is over 10km/h.
Alarm precision

Allowing a 10% miss rate can help achieve an accuracy rate for warnings of
higher than 95%.
