Speed control system and method for a motor vehicle
First Claim
Patent Images
1. Speed control system for a motor vehicle, comprising:
- a unit for calculating a drive torque or brake torque as a function of a pre-definable target speed, the target speed being pre-defined by a single actuation of an operable control element;
wherein a sustained actuation (db) of the control element (BE) pre-defines a target acceleration (as), instead of a target speed (vs), the unit calculating the drive torque (Ma) or brake torque (Mb) from the target acceleration,wherein the calculation of the drive torque (Ma) or the brake torque (Mb) takes into consideration load resistances (L) of the vehicle (F), andwherein the target acceleration is pre-defined as a function of a driving style of the driver.

Abstract
A speed control system is provided for a motor vehicle, including units for calculating a drive torque or a brake torque as a function of a pre-definable target speed, the target speed being pre-defined by the single actuation of an operable control element. A sustained actuation of the control element is used to pre-define a target acceleration, instead of a target speed. The drive torque or brake torque are calculated from the target acceleration.
