Abstract
An apparatus for actuating a torque transmitting system and/or a transmission in the power train of a motor vehicle has a control unit which is used to monitor and/or calculate operational parameters and conditions of the motor vehicle. The control unit remains active after the motor vehicle ignition is turned off, and also stores in memory operational parameters and conditions for subsequent use when the motor vehicle is again activated.
Claims46
In an apparatus for automated actuation of at least one of a torque transmitting system and a transmission in the power train of a vehicle with a driving aggregate, with a control unit which communicates with sensors and which is activated in response to turning on of an ignition system of the vehicle, and with an actuator which is activatable by the control unit to actuate the torque transmitting system, the improvement which resides in that, upon deactivation of the ignition system of the vehicle, the control unit remains active for a period of time dependent upon at least one parameter.
In an apparatus for automated actuation of a transmission in the power train of a motor vehicle with a driving aggregate and a torque transmitting system, with a control unit which communicates with sensors and is activated in response to turning on of the ignition system of the vehicle, and with an actuator which is activatable by the control unit to actuate the transmission, the improvement which resides in that upon deactivation of the ignition system of the vehicle, the control system remains active in dependency upon at least one operational parameter.
In an apparatus for automated actuation of at least one of (a) a torque transmitting system and (b) a transmission in the power train of a vehicle with a driving aggregate, a control unit which communicates with sensors and is activated in response to turning on of the ignition system of the vehicle, and with an actuator which is activatable by the control unit to actuate the torque transmitting system, the improvement which resides in that upon deactivation of the ignition system, the control unit remains actuated for a limited interval of time including the duration of at least one of the trailing, running out and follow-up times, the control unit being arranged to become deactivated upon elapse of said at least one time.
A method of automated actuation of a torque transmitting system in the power train of a vehicle with a driving aggregate and a transmission, with a control unit which communicates with sensors and which is activated in response to turning on of the ignition system of the vehicle, with an actuator which is activatable by the control unit to actuate the torque transmitting system, comprising the steps of
- deactivating the ignition system of the vehicle;
- and
- maintaining the control unit active for a period of time which is a function of at least one parameter.
A method of automated actuation of at least one of (a) a torque transmitting system and (b) a transmission in the power train of a vehicle with a driving aggregate, a control unit which communicates with sensors and is activated in response to turning on of the ignition system of the vehicle, and with an actuator which is activatable by the control unit to actuate the torque transmitting system, comprising the steps of maintaining the control unit actuated following deactivation of the ignition system for a limited interval of time;
- and deactivating the control unit upon elapse of the trailing time including follow-up and running-out time.
