Technologies that Satisfy both Safety and "Driving Pleasure"

To help promote safe driving with a comfortable field of vision and operation while driving, the CX-5, the Atenza/Mazda6, and the new Axela/Mazda3 are equipped with the functions and features below. These features will be introduced in upcoming new models.


Ideal Driving Position

As for the layout of major driving operation devices, including the pedals and the steering wheel, which are interface between man and vehicle, are located in an ideal driving position for a driver with easy to operate and not be tired. The driving position is designed based on the theory of the "comfortable joint-link angle," the joint angle at which the driver of any physical type can exert strength quickly and properly. One such example is New Mazda2 equipped with a telescopic steering wheel as standard equipment ,which is a rare case in the segment of compact car.


TOPICS

Industry-academia collaboration pursuing the "comfortable joint-link angle," to create vehicles that are comfortable and do not tire the driver during driving

To offer a safe and comfortable driving environment, Mazda focuses on an ergonomics-based approach.
In determining the "comfortable joint-link angle" common to many drivers, Mazda developed a special driving tester simulating an actual vehicle, with which the myoelectric measurement data of many human bodies of different height and build were accumulated to develop the concept of comfortable driving postures and operation devices. The analysis of enormous amounts of data has led based on joint research with Human Motion Analysis of Hiroshima University. This concept is reflected in the CX-5 launched in 2012 and subsequent Mazda models.


Excellent visibility

Visible angle expanded by moving A-pillar backward

Mazda considers it important to secure a good field of vision that enables the driver to quickly recognize his/her surrounding situation and take proper action. The A-pillar was placed about 100 mm backward from its position in the previous model to expand the visible angle from the front seat by 1.8 degrees to both the right and the left. Moreover, to expand the vision through the door mirror so as to improve the visibility of pedestrians and obstacles, door mirrors are installed on the outer door board in a lower position.

New-generation HMI (Human Machine Interface)*1

The strictly human-oriented cockpit design enables the driver to concentrate during driving, thereby minimizing three factors that cause careless driving: inattentive looking, inattentive thinking, operation in an unstable position.

HMI concept "Heads-Up Cockpit"

Heads-Up Cockpit

The Heads-Up Cockpit adopted for the new Axela/Mazda3 and subsequent models is designed to ensure that various information communication functions are used safely and comfortably.
Aiming at helping the driver concentrate on driving safely in a correct posture while dealing with many kinds of information, this HMI concept has achieved minimum eye motion and posture change.

  • Simple cockpit with information sorted and placed in different zones
  • A 7-inch center display installed on the dashboard, enabling the driver to view it without lowering his/her eyes (①)
  • Commander control pursuing operation that does not require a visible check of the driver's hand movements (②)
  • Active driving display to present vehicle speed, navigation route and other information as an image in front of the meter hood (③)
  • A voice-recognition system to control the functions by voice is also available
