A method for operating a powertrain, having at least one drive motor and at least one gearbox, of a motor vehicle which can be driven by the drive motor, via the gearbox, in which heat is transferred from the drive motor to the gearbox in a targeted manner, as a result of which the gearbox is heated in a targeted manner. The heat is transferred from the drive motor to the gearbox in a targeted manner on the basis of predictive data which include at least one future state of the motor vehicle.

A vehicle includes a main body, a transmission having a plurality of gear stages, a data storage, and an electronic controller. The data storage stores vehicle running condition data that includes at least one of a prescribed vehicle running condition, a sensed vehicle running condition, or a transmitted vehicle running condition. The electronic controller determines a gear shift of the gear stages of the transmission based on a future vehicle speed that has been estimated based on the vehicle running condition data.

There is provided a control device for vehicles which can improve quietness and fuel economy, while maintaining high responsiveness to acceleration of a vehicle. Therefore, the control device 100 for vehicles includes a gear ratio control unit 10 that controls a gear ratio of a vehicle V, and a determination unit 20 that determines whether or not there is an acceleration limit of the vehicle V. The gear ratio control unit 10 is configured to limit an increase in gear ratio R.sub.t, when the determination unit 20 determines that there is an acceleration limit.

A motor vehicle includes an electronic processor communicatively coupled to an accelerator pedal, a transmission system, and vehicle sensors. The electronic processor detects a driver of the motor vehicle ceasing to depress the accelerator pedal. Dependent upon signals the electronic processor receives from the vehicle sensors, the processor inhibits the transmission system from changing gears in response to the driver ceasing to depress the accelerator pedal.

In a transmission controller for the open-loop and/or closed-loop control of the operation of an automatic or automated manual transmission of a motor vehicle, a shifting strategy of the transmission control unit controls the operation of the transmission in an open-loop and/or closed-loop manner based on driving status data and/or driver intention data. The shifting strategy of the transmission control unit influences a gear change from a current actual gear into a target gear based on available environmental data. In the event of a required down-shift from a current actual gear into a lower target gear, the transmission control unit is configured to take into account available information relating to a traffic light status, in particular relating to a change of a traffic light status of a relevant traffic light.

A system and method for controlling performance of a vehicle engine by sensing and/or accessing data regarding the driving environment and adjusting at least one of an engine output torque limit and a shifting schedule for the vehicle based on the sensed data.

A system and method for controlling performance of a vehicle engine by sensing and/or accessing data regarding the driving environment and adjusting at least one of an engine output torque limit and a shifting schedule for the vehicle based on the sensed data.

A system for controlling a vehicle includes: the vehicle, at least one forward-looking sensor disposed within the vehicle, and a positioning system disposed within the vehicle. The system also includes a processor disposed within the vehicle and configured to: during deceleration of the vehicle, determine, based on inputs from the at least one forward-looking sensor or the positioning system, whether it is likely that a driver of the vehicle will stop decelerating the vehicle and will instead accelerate the vehicle. If it is likely that the driver will accelerate, the processor is configured to inhibit the downshifting of the vehicle's transmission.
