Application of “Anti-slip Readhesion Control with Presumed Adhesion Force” to Commuter Transport Electric Cars

Abstract

Recently trains raise speed and reduce the motor vehicle ratio. It is needed, therefore, to utilize adhesion force more effectively. In running tests of high speed Shinkansen train, it has become clear that slip and readhesion repeat under strict adhesion conditions as far as they rely on the conventional concept of readhesion control. So we have developed a new control method “Anti-slip Readhesion Control with Presumed Adhesion Force” and confirmed in running tests its various effects. Furthermore, we apply it to commuter transport electric cars to research various points such as effects of control improvement, control parameters which are suitable for it, differences between with presuming and without presuming adhesion force, and so on. In running tests, we confirmed that we can utilize adhesion force more effectively by applying the newly developed control method to commuter transport electric cars.
