Patent number: 5908225Abstract: A process for ensuring a neutral vehicle handling during cornering and a simultaneous load change is provided by the operation of a vehicle system having at least one driven axle, an axle differential gear, wheel brakes for the selective deceleration of an individual wheel, a device for recognizing a cornering and a device for recognizing a coasting operation and for generating a signal corresponding to the intensity of the coasting operation. The problem of rear-wheel driven and front-wheel driven vehicles is the vehicle handling during cornering in the coasting operation. As a result, depending on the method of operation, an oversteering or understeering of the vehicle is caused. The process avoids these problems in that, during a cornering, a wheel of the driven axle is decelerated at least as a function of the coasting operation signal such that the moment generated thereby, such as a counter-yawing moment, compensates the yawing moment caused by the cornering during the coasting operation.Type: GrantFiled: February 27, 1997Date of Patent: June 1, 1999Assignee: Bayerische Motoren Werke AktiengesellschaftInventor: Kurt Meier
