Automobile Technology

Head-on Collision Avoidance Assistance System

  • When an approaching vehicle is hidden from view, for example around a blind curve, the system communicates with the oncoming vehicle to ascertain important information such as its position, speed, and steering wheel angle. If the driver begins to change lanes into the path of an oncoming vehicle, the accelerator pedal vibrates and torque is applied to the steering wheel (pulling in the opposite direction from the driver), sending a tactile warning that prompts the driver to return to his or her own lane.

Cornering Speed Control System

  • As a vehicle approaches a curve, this system uses information from the vehicle's navigation system to assess the curvature of the road, and calculates the vehicle's appropriate speed. If the vehicle is traveling above that speed, the system applies the brakes to slow the car to the appropriate speed.
  • When a vehicle encounters unexpected changes in road conditions, such as a lane closing or road work not reflected in the navigation system data, the system uses information acquired from vehicles ahead traveling in the same direction and oncoming vehicles to determine the appropriate speed for the current road conditions.

Adaptive Cruise Control System

  • If a vehicle one or two vehicles ahead of the car slows down in a place such as a blind curve, where the vehicle can not be detected by radar, the Inter-Vehicle Communication System acquires deceleration data and calculates the appropriate speed for the car. If the car is traveling above the appropriate speed, the system issues an audio warning, and reduces the speed of the car.
  • If the vehicle directly ahead of the car is detectable by radar, the system uses the radar information to calculate the appropriate speed for the car (as with the existing Intelligent Highway Cruise Control system).
  • Using inter-vehicle communication technology in parallel with radar allows the system to acquire and report a broader range of information about the vehicle ahead.

Advanced Adaptive Frontal-Lighting System

  • Cars traveling at night exchange positional information via the Inter-Vehicle Communication System. As the vehicles approach a point close enough that one of the drivers could be blinded, the system automatically switches the headlights to low beam.
  • Even when visibility is limited, the system automatically switches the headlights to low beam just before vehicles pass each other to avoid blinding the driver of the oncoming vehicle.

Pedestrian Detection, Vision-Based Pedestrian Detection System

  • This system uses the Inter-Vehicle Communication System in combination with image analysis technology to detect pedestrians hidden from view who previously would suddenly appear on the road. The system issues the driver a warning and displays the pedestrian's location.
  • The system communicates with a pedestrian's portable transmitter to detect his or her presence in cases where he or she may be blocked from the driver's view, alerts the driver by sounding a warning, and then displays the pedestrian's location on the navigation system screen.
  • The system recognizes pedestrians by analyzing images captured by on-board cameras. If the pedestrian is located on the road, the system visually alerts the driver by placing a frame around the figure of the pedestrian displayed on the screen. Based on the vehicle's speed and distance to the pedestrian, the system determines if there is a risk of collision and, if so, issues a warning to the driver.
  • This system uses the Inter-Vehicle Communication System in combination with image analysis technology to achieve early detection of pedestrians.

Forward Obstacle Avoidance Assistance System

  • This system provides compensatory steering and braking assist when a driver is slow to take evasive action when unexpectedly confronted with another vehicle or object appearing in the vehicle's path.
  • The radar system determines if another vehicle is in a driver's path. If the driver takes evasive action such as steering sharply away from the other vehicle, this system assists with steering and brake assists to support the driver.
    1. At the start of evasive action: the system provides steering assist to help the driver avoid the obstacle.
    2. During evasive action: the system reduces steering input to help prevent the driver from turning too sharply.
    3. After evasive action: the system provides steering assist if the driver is slow to return the vehicle to its original course, helping prevent the vehicle from spinning out of control.
  • This system assists drivers in taking evasive action, and then helps stabilize the vehicle.

Intersection Collision Mitigation Brake System

  • This system uses on-board cameras, and radar to detect when a vehicle suddenly appears from the side, for example at an intersection. If the system determines that a collision may occur, it provides an audio warning and physically alerts the driver by intermittently applying light braking, and gently tightening the seatbelt.
  • If the system determines that a collision is unavoidable, it prepares to mitigate damage and injuries which may result from impact by applying strong braking and firmly tightening the seatbelts to enhance the proper restraint of passengers.
  • Honda has commercialized a system designed to mitigate vehicle damage and injuries in rear end collisions, the Collision Mitigation Brake System, which was first available on the 2003 model Inspire in Japan. This experimental Intersection Collision Mitigation Brake System goes further, adding response to potential lateral collisions.

Advanced Mayday System

  • Should an accident occur, this system automatically notifies the Honda Operation Center and transmits an array of data about the accident, including the location, vehicle type, the deployment status of the airbags, and 15 seconds of video taken inside and outside the vehicle just before and after the moment of impact.
  • Using two-way video and voice transmission, operators at the Operation Center can communicate with the occupants of the vehicle and assess their condition in real time.
  • On-board body sensors enable the Operation Center to measure the driver's heart rate, respiration rate, and other vital signs.
  • If an accident occurs out of range of mobile telephone signals, the Inter-Vehicle Communication System may be able to contact the Operation Center by relaying data through other vehicles.

Intersection Collision Mitigation Brake System

  • The 5.8 GHz communications equipment featured on motorcycles and automobiles enables two-way, wireless transmission of data, such as vehicle type, position, direction, and speed.
  • Portable communications devices which can be carried by pedestrians can wirelessly transmit the pedestrian's position.
  • The system supports communications up to a maximum of 120 vehicles within a distance of up to approximately 200 meters.
