Method and system for improving the driving behavior of a vehicle
A method for a Sensitive Electronic Stability Program (SESP) presents a general approach for the correction of maneuvers of turning into a bend at low speed. It integrates existing methods as well as subsequent extensions. SESP supplements the standard active yaw control (AYC) function. This allows the SESP to use variables and mechanisms of AYC, on the one hand. On the other hand, AYC continues operating unimpeded in the background and will intervene as usual when SESP cannot stabilize the vehicle appropriately. When the standard AYC intervenes, SESP control operations are forbidden, or running SESP control operations are stopped. This stop can take place either abruptly or (which is more comfortable) by way of a moderate decrease of the correcting variables.
1. A driving situation detection system for observing and analyzing driving situations of a vehicle, at least including the situations of straight travel and cornering,
wherein the system is capable of observing and analyzing driving situations with almost steady-state courses of the vehicle at a steering angle velocity of lower than, or equal to, 120°/s, wherein the system is designed as a state machine capable of detecting at least one of the states which are members of the group consisting of straight travel with partial braking, cornering with partial braking, and cornering with a change of load; and wherein the system is capable of activating a controller depending on the states which reflect a course deviation,
the detection system being connected to a reference signal model in which a YTC reference variable with an offset is corrected by means of an offset value, wherein the driving situation detection system determines the time at which the offset correction is started and terminated, and the offset value is superposed on the reference variable at the starting point.
