Development of Advanced Brake System for Small Motorcycles

Combined Brake System for small motorcycles has been developed. In small motorcycles, some models have a hydraulic disc brake both in the front and rear wheels but many of them have a hydraulic disc front brake and a mechanical drum rear brake. Accordingly, it was necessary to develop a new system to link the hydraulic system with the mechanical system to allow an application of Combined Brake System to these models. In this paper, a CBS having a new configuration is described where a disc brake and a drum brake are linked in a simple lever structure of an input force distributor, and an inhibitor spring at the foot pedal. With this mechanism equipped, the distribution of brake forces is controlled. When a large input force is applied, a large proportion of brake force is applied to the front brake to obtain adequate deceleration. When a mild input force is applied, which is frequently operated, the brake force proportion is large in the rear compared to the front.

New Telematics Approach by “Diversifying Communication and Customer Opportunity”

Customer satisfaction is one of the most important goals for car manufacturers in providing telematics services to their customers. Telematics is not merely a chance for additional revenue, but should be used to supplement value to an OEM's core business. Unfortunately most existing Telematics business models focus on revenue opportunities. However, the customer value of Telematics still resides in a conventional vehicle–related value model. Typical examples of killer applications are related to transportation, such as real time traffic information, vehicle operation information, vehicle diagnostic information and on–board entertainment. A new approach, which is well accepted by customers, is anticipated. The key solution is a combination of several challenges, such as the transformation of customer relationship management (CRM), optimum integration of existing infrastructure, and customer value proposition based on customers' essential expectations.

Improvement of visibility for vulnerable parties in traffic accidents

More than half of fatalities in traffic accidents in Japan are the vulnerable parties in such accidents (pedestrians, motorcycles, bicycles). In most of these accidents, the cause is collision involving automobiles. Therefore, reasoning that early detection of such vulnerable parties would lead to a reduction in accidents, we conducted research on the following three systems: - Honda Night Vision System - For night-time detection of pedestrians using infrared cameras. - Active Headlights - For assuring night-time field of vision by directing illumination in the direction of vehicle travel through lights coupled with steering wheel turn and so on. - Inter-Vehicle Motorcycle-Automobile Communication System (IVCS) - Notifies drivers of each other's presence by providing information through communications systems installed on both vehicles. The results from research on these systems show that their use can be expected to have a positive effect in reducing the occurrence of accidents.
