There are certain conditions under which Honda Sensing-related features may not engage or operate, including inclement weather (such as snow, ice or heavy rain), and extreme cabin heat (due to operability of the camera).
Collision Mitigation Braking System™ (CMBS™)
All CR-V models with Honda Sensing™ offer the Collision Mitigation Braking System (CMBS), one of the most sophisticated safety technologies available. An automatic emergency braking system, CMBS features a millimeter wave radar unit, located behind the front grille, and monocular camera, located between the rearview mirror and windshield, to scan traffic conditions ahead of the vehicle.
When the system determines a collision is possible with a detected vehicle, the integrated Forward Collision Warning (FCW) system’s visual and audible alerts prompt the driver to take corrective actions. The visual alert appears on the Multi-Information Display (MID). If the situation is not resolved, CMBS can apply different levels of autonomous braking action to help reduce vehicle speed and eventual collision forces, and therefore to help reduce the severity of a collision if the driver doesn’t take corrective action on their own. The radar unit and camera work simultaneously and cooperatively to control the VSA/EBB modulator, which initiates any required braking.
Due to the effectiveness of its monocular camera, CMBS can recognize shapes and differentiate between a vehicle and a pedestrian, warning the driver in each case.
It is important to note that CMBS cannot detect all objects ahead, nor is it intended to replace the driver’s assessment of traffic conditions and control of the vehicle. The driver must intervene in certain situations, and must always be attentive when using the system. Although in many cases CMBS will stop the vehicle, it is not intended to apply enough braking force to prevent all collisions. Based on the conditions, the system also may not perform all visual- and audible-alert stages, and may instead automatically engage the brakes if the system deems it necessary. CMBS may be turned off by pressing the CMBS button on the left side of the dash.
Forward Collision Warning (FCW) – Integrated with CMBS
Forward Collision Warning (FCW) is included in trims with Honda Sensing. Integrated with CMBS, Forward Collision Warning (FCW) uses a monocular camera and a millimeter-wave camera to detect vehicles ahead and to determine whether a collision is likely. This reduces the stress of driving in traffic, while also contributing to an increased level of passive safety.
If the FCW system detects a vehicle in front of the CR-V and then determines that a collision may occur (due to a speed differential between the 2 vehicles), it will trigger visual and audible alerts for the driver. These include a “BRAKE” message on the Multi-Information Display (MID), and a series of beeps to alert the driver to apply the brake pedal. The FCW system will not automatically brake, and the driver remains responsible for safely operating the vehicle and avoiding collisions. If the driver doesn’t respond to the FCW warnings, however, the CMBS is triggered into operation.
Drivers may adjust the distance at which FCW alerts occur between “Long,” “Normal” or “Short.”
Note that the FCW system cannot detect all objects ahead and may not detect a given object; accuracy will vary based on weather, speed and other factors.
Lane Keep Assist System (LKAS)
Lane Keeping Assist System (LKAS) provides a less stressful driving experience by reducing the need for steering correction movements and driving effort on the highway. LKAS uses a camera to read lane markings and uses Electric Power Steering (EPS) to assist the driver in maintaining their position within the lane.
Designed for the U.S. road structure, the system uses a monocular camera mounted on the upper portion of the windshield to identify painted lanes, Botts’ dots and cats eye markers at speeds between 45 mph and 90 mph. When LKAS senses that the driver is drifting from the middle of a detected lane, the system generates corrective steering torque to assist the driver in maintaining lane position.
LKAS may be activated and deactivated using a switch located on the right side of the steering wheel. The system will suspend operation after several seconds if the driver either takes his or her hands off the wheel or does not grip the wheel strongly enough. Operation suspension is accompanied by a visual warning and corresponding vibration/oscillation of the steering wheel, resuming when the driver makes a steering input.
Road Departure Mitigation (RDM)
Integrating Lane Departure Warning (LDW) (see below), Road Departure Mitigation (RDM) is new for the 2017 CR-V. It uses a monocular camera (mounted on the upper portion of the windshield) to identify solid or dashed painted lane lines, Botts’ dots and cats eye markers. RDM uses steering force, via EPS to help the CR-V stay in its lane and, if the vehicle is detected leaving a lane marked by solid lines, braking force, via Vehicle Stability Assist (VSA)/Electric Brake Booster (EBB), to keep the vehicle from departing the lane or roadway altogether.
The monocular camera recognizes lane features and identifies the lane. If the RDM system determines that the CR-V is about to leave a detected lane, it will provide steering assist (primary) and in rare occasions when steering assist is not sufficient to avoid leaving a lane marked by a solid line, braking assist, to help the driver stay on the road. RDM is integrated with the VSA system to provide moderate braking, and with the Electric Power Steering (EPS) system to provide steering input.
Visual and steering wheel vibration warnings alert the driver when the RDM system is taking corrective action, including a lane departure warning on the Driver Information Interface (DII).
RDM also has a customizable initial warning of the steering wheel shake/vibration and can also cancel driving assistance. This can be customized in the vehicle settings. RDM can be turned off completely by using the RDM Off button on the left of the dashboard.
Lane Departure Warning (LDW) – Integrated with RDM
Lane Departure Warning (LDW) is designed to alert the driver if the vehicle is leaving a detected lane without the turn signal being activated. The system functions at speeds from 45 to 90 mph on straight or slightly curved roads, alerting the driver of deviations from a detected lane. The LDW system utilizes the same upper front windshield camera used for Honda Sensing-related features, and provides the visual and vibration alerts prior to the other systems actively engaging.
If the vehicle begins to move out of a detected lane without the turn signal activated, LDW illuminates a Lane Departure message on the Multi-Information Display (MID) and sounds an audible warning, advising the driver to take appropriate action. The system can be activated and deactivated by pressing the LDW button located on the left of the dashboard.
Adaptive Cruise Control (ACC) with Low-Speed Follow (LSF)
Adaptive Cruise Control (ACC) allows the driver to set a desired speed and following interval from a vehicle detected ahead, allowing the use of cruise control on the highway in light traffic conditions. This significantly reduces the driver stress of driving in traffic. The system uses the millimeter wave radar and monocular camera to continually track the distance to the vehicle detected ahead, and then adjusts the CR-V’s speed to maintain the set following interval. A short, medium, long, or extra-long interval can be selected. When required, the CR-V autonomously brakes using the VSA/EBB modulator. Integrated Low-Speed Follow (LSF) extends the automatic following capability to stop-and-go traffic situations (down to 0 mph).
ACC operates in the following ways in the listed circumstances:
- A preceding vehicle is detected in the lane ahead – Decelerates automatically, if required, and then controls the following distance.
- The preceding vehicle slows to a stop – Stops automatically and remains stationary.
- The preceding vehicle accelerates from a stop – Resumes following when the SET or RES switch or accelerator pedal is operated.
- Another vehicle merges in between the CR-V and the preceding vehicle – Automatically switches “targets” to the nearest detected preceding vehicle.
- The preceding vehicle exits the lane – ACC system continues at cruise-control speed previously selected by driver (25 to 90 mph).
A Driver Information Interface (DII) message and audible warning alert the driver when the ACC function is activated.
Auto High-Beam System (AHB)
The auto high-beam (AHB) system, included with EX and above trims, makes optimal use of the vehicle’s headlights. When the headlight switch is set in the Auto position, the system automatically illuminates the high beams until an integrated camera detects oncoming or preceding traffic and automatically switches to low beams.
Blind Spot Information(BSI) System
CR-V EX and above trims feature an advanced blind spot information system, or BSI. This technology uses radar sensors to detect the presence of vehicles to the side and behind the CR-V and is designed to help the driver when changing lanes. If the system determines a vehicle may be in the driver’s blind spot, BSI automatically alerts the driver by activating a warning indicator.
Driver Attention Monitor
Making its Honda debut on the 2017 CR-V EX and above trims, on highway and arterial roads the Driver Attention Monitor continually monitors and assesses driver behavior behind the wheel to help determine if the driver is becoming inattentive – and then if so, warn the driver to take a break. The system uses input from the Electric Power Steering (EPS) to measure both the frequency and severity of the driver’s steering inputs to gauge their level of awareness with four gradients.
When the Driver Attention Monitor is activated, the driver is first alerted by a coffee cup icon and a 4-level bar graph that is displayed on the MID below the speedometer and tachometer. The bar graph indicates full attention with 4 white bar elements are illuminated. As the driver attention drops, fewer and fewer bars are illuminated. When the number of bars drops to two, a message inviting the driver to take a break is illuminated. If the driver continues driving and the graph drops to the lowest level of one bar, a beeper sounds and the steering wheel vibrates, prompting the driver to pay closer attention or take a rest break.
Cross Traffic Monitor
In EX and above trims, the Cross Traffic Monitor works in conjunction with the BSI radar sensors to enhance driver confidence when backing up. The system is especially useful when reversing in congested parking lots with an obstructed view from driver’s seat.
The system utilizes a pair of blind-spot radar units located in the rear bumper corners. When Reverse is selected and an approaching vehicle is detected, arrows indicating the approaching vehicles direction are shown on the 7-inch display’s rear camera image as well as an audible warning.
