The correction module is connected to the transmission, to the device for acquiring information about the surroundings, and to the device for acquiring driver data and/or vehicle data. In addition, a method for determining a gear ratio change in an automatic transmission of a motor vehicle using the devices of the system is provided.
摘要:
The invention relates to a method for detecting a driving situation ahead of a motor vehicle. In a first step, a first function (f—1) is evaluated, which calculates a variable path length ahead (I_vor) as a function of a current vehicle speed (v) and a current degree of sportiness (gsp). In a second step, a second function (f—2) is evaluated, which calculates the road course data (str_vor) at least as a function of the variable path length ahead (I_vor) and environment data (u). In a third step, a third function (f—3) is evaluated, which calculates a possible driving situation ahead (sit_cand) at least as a function of the road course data (str_vor), the vehicle speed (v) and the degree of sportiness (gsp). Finally, in a fourth step, a fourth function (f—4) is evaluated, by means of which a driving situation ahead (sit_vor) is detected at least as a function of the possible driving situation ahead (sit_cand). The detected driving situation ahead (sit_vor) can be used, for example, to influence electronic and/or mechanical vehicle systems, such as electronically controlled vehicle transmissions.
摘要:
A control system for controlling a vehicle with a hybrid drive comprising an internal combustion engine and an electric motor and a plurality of functional components each divided into strategy, control and actuator sub-components. The functional components include engine, transmission and hybrid functional components. The strategy sub-component of the hybrid functional component comprises an operating status prescription module which determines a recommended value for the operating status of the hybrid drive and transmits the recommended value to the control sub-component. The possible recommended value that can be determined by the operating status prescription module is a preselected hybrid driving condition, and if the operating status prescription module of the strategy sub-component transmits the preselected hybrid driving condition, as the recommended value, to the control sub-component, then the strategy sub-component prescribes a change from electric to hybrid driving, while the control sub-component determines when change occurs.

摘要:
A method for predictive determination of gear ratio changes in an electronically controlled transmission. Environment data (12), driver/vehicle data (11) and information about a first proposed gear (10) are fed to a correcting module (13) which comprises at least one driving situation module (14) and a determining module (15). The determining module (15) evaluates, in a first step (2), whether at least one shifting situation for a procedure exists. If at least one shifting situation exists, evaluating, in a second step (6), whether also the conditions for carrying out the respective procedure for one of the detected shifting situations exist. If a shifting situation has occurred and the conditions for performing a procedure exist, the first proposed gear (10) is adapted in a third step and an adapted second proposed gear (17) is determined, the information of which is forwarded to the transmission (18).
