Ichikoh Industries: Camera Monitor System (CMS)

Ichikoh Industries exhibited a next-generation rear-facing vision system that replaces conventional rearview and door mirrors with cameras and displays. The CMS specifications feature a liquid crystal shutter that switches between monitor mode and mirror mode, as well as an anti-glare function. By replacing the door mirrors with downsized cameras, the vehicle's aerodynamic performance and design performance can be improved. The CMS can provide driver assistance by image analysis that detects the vehicle's surrounding situation to alert the driver if necessary when a vehicle close by is going to change lanes. The CMS automatically changes the angle of view of the images displayed according to the driving conditions.

The prototype of the camera monitor system (CMS) exhibited at this event used a camera only with no mirror design for the right side of the vehicle, but on the left side of the vehicle used the hybrid mirror design that combines a conventional door mirror with camera for those countries that mandate vehicles be equipped with conventional door mirrors. Cameras are equipped with the Sensor Cleaning System displayed by Valeo.

3D Surround Multi View

Images are captured by four high-resolution cameras (approximately 1 million pixels), synthesized in real time as a three-dimensional model, and displayed as a high-quality 360 degree seamless image on the monitor. It also supports driving safety by automatically changing the view when turning right or left and when parking because the system interfaces with the turn signal and reverse gear. Also, good visibility is secured using a 190-degree wide angle camera that switches to the front view of the vehicle at intersections with poor visibility.
