  • Patent number: 10246093
    Abstract: A method for operating a motor vehicle generates a change-operating-mode signal to change operation from a normal mode with an engine engaged and running to a coasting mode with the engine disengaged and/or switched off in response to a freewheeling distance exceeding a threshold. The freewheeling distance may be based on state parameters of the motor vehicle, such as position, speed, acceleration, weight, tire pressure, braking pressure, and air resistance, for example, data related to a second vehicle obtained from forward sensors, for example, and/or ambient parameters such as air temperature, wind speed, and wind direction, for example.

  • Patent number: 10239533
    Abstract: A method for anticipatory or predictive operation of a motor vehicle having a drive control system by which drive-relevant components of the drive-train are adjusted, and a detection system by which a travel route and anticipated driving time to a specified destination as well as the current position of the vehicle are determined. By way of the detection system and based on topographical information, a driving resistance profile of the route is prepared, to parameterize the drive control system such that the route is driven in a specifiable manner. If a need arises during the journey, a nominal arrival time or a travel route is specified or modified and, in accordance with the specified or changed nominal arrival time or route, the drive control system is dynamically re-parameterized so that the vehicle reaches its destination at the time concerned with regard to an efficient mode of operation.

  • Patent number: 10190681
    Abstract: A protection control selection unit is provided. The protection control selection unit selects control that uses one of a completely engaging heat generation amount and a releasing heat generation amount, by which the amount of heat that is generated in a lockup clutch is reduced. The completely engaging heat generation amount is generated in the lockup clutch in a period before the lockup clutch is completely engaged from a state of lockup engagement control. The releasing heat generation amount is generated in the lockup clutch in a period before the lockup clutch is released from the state of the lockup engagement control. Thus, an increase in the temperature of the lockup clutch at the time when the lockup clutch is completely engaged or released from the state of the lockup engagement control is suitably suppressed.
