Temporary compensation of undesired deceleration due to braking interventions by ESP functions

摘要

A method for compensating for the change in longitudinal dynamics variables in a motor vehicle brought about by a braking intervention of an electronic stability program (ESP) includes: identifying the change in longitudinal dynamics variables; defining a filter to filter the identified value of the change in longitudinal dynamics variables; filtering the identified value of the change using the defined filter, in order to obtain a filtered value; identifying the difference between the identified raw value and the filtered value of the change in longitudinal dynamics variables; modifying the engine torque that is requested by the driver and is acting on the drive wheels of the motor vehicle, by an amount equal to the identified difference value, in order to obtain a compensating engine torque.

1. A method for temporarily compensating for a longitudinal deceleration in a motor vehicle brought about by a braking intervention of an electronic stability program, comprising:
identifying a raw value of change in at least one longitudinal dynamics variable brought about by the braking intervention; defining a filter to filter the identified raw value of change in the at least one longitudinal dynamics variable; filtering the identified raw value of change in the at least one longitudinal dynamics variable using the defined filter, in order to obtain a filtered value of the change in the at least one longitudinal dynamics variable; identifying a difference value between the identified raw value and the filtered value of the change in the at least one longitudinal dynamics variable; and modifying, as a function of the identified difference value, an engine torque which is requested by a driver of the motor vehicle and acting on drive wheels of the motor vehicle, in order to obtain a compensating engine torque.
