Honda SENSING functions that support driving from various perspectives.

Collision Mitigation Braking (CMBS)

The Collision Mitigation Braking System or CMBS is part of the Honda Sensing technology that helps keep all drivers safe. This system, in particular, reduces the likelihood of a frontal impact. A forward-facing camera and a radar transmitter make it possible to determine the distance and closing speed of detected objects that lie directly in front of your vehicle.

How CMBS works in Honda Vezel ?

When the vehicle speed of the your vehicle reaches 5 km/h or more, the radar sensor and camera start detecting vehicles and pedestrians in front. CMBS may operates when there is a risk of collision with vehicles and pedestrians whose speed difference from your vehicle is approximately 5 km/h or more. It operates when the system determines that, and automatically stops or decelerates to avoid collisions and reduce collision damage.

For oncoming vehicles and pedestrians, it operates when the vehicle is traveling at a speed of approximately 80 km/h or less and there is a risk of collision.

In addition, if the CMBS is activated for an oncoming vehicle while driving at approximately 30 km/h to 80 km/h, a warning due to steering vibration will also be activated. After the CMBS is activated and it is determined that the oncoming vehicle has stopped or there is no risk of collision, the automatic brake will be released.

The CMBS informs the driver that there is a risk of collision by the following methods. In addition to the warning display and warning buzzer on the multi-information display, the accelerator pedal will be warned by intermittent reaction force and steering vibration.

CMBS Alarm distance can be selected from 3 level: Far, Normal, and Near.

CMBS Alert Stages in Honda Vezel

There are 3 stages in the operation of the CMBS, depending on the possibility of a collision. However, depending on the situation, it may operate from the middle stage.

Limitations of CMBS

1) CMBS is not a system that can avoid collisions in all situations. Radar and camera can be difficult to detect depending on the weather, speed and road conditions.

2) Need to keep sufficient distance between vehicles.
3) When the EPS (Electronic power steering) warning light on, the warning due to steering vibration does not work.
4) CMBS disable automatically under following conditions.

When driving on mountain roads or rough roads for a long time
When driving with the parking brake applied
When the weather is bad, such as rain fog or snow.
When the temperature of the camera is high
When the front grill or windshield is covered with dust, mud, fallen leaves, damp, snow, etc.
When the CMBS ready to operate when a tire abnormality is detected, CMBS will automatically return.

Note:- Please turn off CMBS when using chassis dynamometer or free roller during vehicle maintenance and inspection.

5) In the following cases, the radar sensor or camera may not be able to detect the vehicle or road surface conditions, and CMBS may not operate.

> Cases where the radar sensor or camera cannot detect correctly depending on the condition of vehicle.

- When the front grill is dirty

- When the front of the camera is covered with cloudy windshield, raindrops, stickers, ets.

- When the car is tilted with heavy luggage in the cargo space or rear seat.

- When not using the right tires

- When strong light is reflected on vehicles, pedestrians and road surfaces

- When there is a splash of water or a roll of snow from a vehicle in front

> Cases where radar sensor and camera cannot detect correctly due to road conditions.

- For carps, rolling roads, slopes, etc.

- When there is a puddle or a water film on the road surface

- On rutted roads such as snowy roads and dirt roads.

- When there is something that strongly reflects radio waves around vehicles or pedestrians, such as when driving on a narrow iron bridge.

Note:- Do not modify the suspension. The system may not work properly. Use tires of the same specified size, same type, same brand, and no wear running on all four wheels. Using tires of different sizes, types, brands and wear levels may cause the system to malfunction.

> Cases where the radar sensor and cameras cannot detect correctly due to the conditions of vehicle in front, oncoming vehicles, and pedestrians.

- When the distance to the vehicle or pedestrian in front is extremely short

- When the vehicle suddenly cuts in front of your vehicle

- When an oncoming vehicle or pedestrian jumps out in front of your vehicle

- When some pedestrians (head,limbs,etc.) are hidden by luggage, etc.

- When a pedestrian is in the background and the camera cannot detect the pedestrian

- When a pedestrian is leaning forward or crouching, raising his hand or running

- When the height of the pedestrian is about 1m or less, or about 2m or more

- When pedestrians are in a group

- When the vehicle in front is unlit in the dark

> Other cases that cannot be operated

- Suddenly when the driver operates the brake or steering wheel in an attempt to avoid a collision

- Approaching a vehicle in front, an oncoming vehicle, or a pedestrian while suddenly accelerating or operating the steering wheel.

- When there are no vehicles in front, oncoming vehicles, or pedestrians in front of your vehicle.

- When the speed difference with the vehicle or pedestrian in front is large.

- When the vehicle in front suddenly slows down.

- For bicycles, motorcycles, wheelchairs, vehicles with special shapes, etc.

- When a vehicle jumps out in front of your vehicle at a intersection, etc.

- When the camera cannot detect correctly as a pedestrian.

How CMBS can be On and Off Manually

By pressing the CMBS switch, it is possible to Off or On the CMBS feature. Beep sound hear when the status changed and CMBS warning light turns on and message "CMBS OFF" is displayed on the multi-information display. Even if you switched off the CMBS, turning off the power mode and switching on will again automatically switch on the CMBS.

False Start Suppression (False start prevention)

The false start suppression function operates when the vehicle is stopped or traveling at a speed of about 10 km/h or less, even though there is an obstacle such as a vehicle in a short distance in front of the vehicle, and accelerator pedal is depressed. In such situations, False Start Prevention function will Suppresses the output of power systems such as engines and motors and prevents sudden starts, and notifies to the driver through visual and audible warnings and vibrations to the acceleration pedal.

How False Start Prevention Function works?

The Millimeter-wave radar detects vehicle directly in front or other objects in close range while the vehicle is stopped or while driving at a very low speed(Less than 10 km/h). If the driver presses down the acceleration pedal too suddenly while there is an object in front, the system prevents sudden acceleration and the buzzer (beep) sounds, the warning on the multi-information display flashes, and at the same time, the accelerator pedal is forced to return to its original state (Intermittent reaction force).

In addition, it does not work when the steep slope or shift position is in "P","R", or "N". The False Start Suppression Function uses the same sensors as CMBS. When CMBS is turned off, the false start suppression function does not work.

Conditions for cancelling the operation automatically

When the accelerator pedal is released
When the accelerator pedal is depressed for about 4 seconds
When you step on the brake pedal
When you operate the steering wheel and try to avoid a collision
When the CMBS is turned off

Operation Limitations

If you are trapped inside the the railroad crossing, the barrier may be detected as an obstacle. In that case, do not panic and keep pressing the accelerator pedal, or turn off CMBS and push the barrier away.

If false start suppression function is activated and you cannot get over the step on the road, turn off CMBS.

Pedestrian Collision Mitigation Steering System (Pedestrian accident reduction steering)

Pedestrian accident reduction steering supports avoidance by steering operation when the system predicts lane departure to the pedestrian side and collision with pedestrians while driving at about 10 km/h to about 40 km/h. I will. It is not a substitute for the driver's steering operation. If the system determines that the driver is accelerating, braking, or steering suddenly, it will not operate if the blinkers are activated.

Pedestrian Collision Mitigation Steering System Operating Conditions

Vehicle should deviate from the lane towards the pedestrian while the pedestrian is walking on the road.
Solid white line (Yellow line) should be continuous.
The vehicle speed should be about 10~40 km/h.
Vehicle should be driving on a straight road.

Pedestrian Collision Mitigation Steering System does not Operate in the following conditions

When the wiper is operating continuously.
When the turn signal (winker) is in operation.

How Pedestrian Collision Mitigation Steering System works

The Pedestrian Collision Mitigation Steering System detects pedestrians and boundary lines on side strips to help avoid collisions.

When the system forecasts a collision with a pedestrian as a result of the vehicle straying from the lane toward the side strip, it provides audio and visual warnings to alert the driver. It also turns the steering wheel in the other direction to assist the driver's collision avoidance effort.

The millimeter-wave radar and monocular camera detect pedestrians and road lanes, helping to protect pedestrians from accidents.

How to ON & OFF Pedestrian Collision Mitigation Steering System ?

The pedestrian accident reduction steering is activated when the Road Departure Mitigation (RDM) function is ON. Press the RDM button to switch between ON & OFF. When it is ON, the indicator of the RDM button lights up and a message is displayed on the multi-information display.

Also, you can customize the settings of the off-road deviation suppression function using the multi-information display. If "No steering assist alarm only" is selected in the customize function, pedestrian accident reduction steering does not perform steering control.

Road Departure Mitigation (RDM) system (Off-Road Deviation Suppression Function)

The monocular camera detects the lane boundaries, and if the vehicle is likely to stray from a detected lane, the system will give a visual warning on the display and vibrations on the steering wheel. In addition, the system will apply corrective steering input to bring the vehicle back in the lane. When the system forecasts that the vehicle is straying too far off, the system will apply braking force to prevent the vehicle from driving off the road.

How RDM Works?

The RDM function is activated when the vehicle is traveling at a speed of approximately 60km/h to approximately 100km/h and the system predicts an out-of-road. It is not a substitute for the driver's steering operation. If the system determines that the driver is accelerating, braking, or steering suddenly, it will not operate if the blinkers are activated.

Adaptive Cruise Control (ACC)

ACC operates at about 30km/h or more. Use this when driving on highways or motorways where there are few sharp curves or repeated acceleration / deceleration.

Click here to see how to use ACC

Lane Keep Assist System (LKAS)

LKAS operates at about 65km/h or more. It is not a substitute for the driver's steering operation. If the system determines that the driver has let go of the steering wheel or that the driver is intentionally steering to cross the lane, it will not operate if the turn signal is activated. Use this when driving on highways or motorways where there are few sharp curves or repeated acceleration / deceleration.

Lead Car Departure Notification System (Preceding Vehicle Start Notification Function)

The millimeter-wave radar detects when the car in front starts from standstill traffic, and notifies the driver with audio and visual alerts if the accelerator pedal is not depressed.

The preceding vehicle start notification function operates when the distance from the preceding vehicle is within about 10m and the own vehicle continues to stop even if the preceding vehicle starts.
