First Claim
Patent Images
1. A motor vehicle comprising a power train including a prime mover, an automatically actuatable transmission and a torque transmitting system;
- at least one control unit switchable between an operative condition where the at least one control unit is in an on state and an inoperative condition where the at least one control unit is in an off state;
actuating means between said at least one control unit and said transmission to actuate said transmission in the operative condition of said at least one control unit;
a starting device for said prime mover, said device having activated and idle conditions and being operative to change a prevailing condition of said at least one control unit in response to a change between said activated and idle conditions; and
means for monitoring activities of an operator of the vehicle and for transmitting to said at least one control unit signals effecting a change from the inoperative to the operative condition of said at least one control unit in response to detection of actuation of a brake by the operator.

Abstract
An electronic control unit for an automated transmission and/or an automated clutch in the power train of a motor vehicle is connected with one or more sensors denoting one or more activities by the operator of the vehicle. The control unit can become operative in response to a signal denoting the actuation of a brake and/or in response to a signal denoting that the ignition system of the vehicle has been operated to start the engine.

21. A motor vehicle comprising a power train including a prime mover, an automatically actuatable transmission, a starting device activatable to start the prime mover and an automatically actuatable torque transmitting system;
- at least one control unit switchable between an operative condition where the at least one control unit is in an on state and an inoperative condition where the at least one control unit is in an off state;
first actuating means operating between said at least one control unit and said transmission to actuate said transmission in the operative condition of said at least one control unit;
second actuating means operating between said at least one control unit and said torque transmitting system to actuate said system in the operative condition of said at least one control unit; and
means for monitoring activities of an operator of the vehicle including a first sensor arranged to transmit to said at least one control unit first signals effecting a change from the inoperative to the operative condition of said at least one control unit in response to detection of at least one first activity of the operator including an actuation of a brake, and a second sensor arranged to transmit to said at least one control unit second signals effecting said change from the inoperative to the operative condition of said at least one control unit in response to detection of at least one second activity other than actuation of said brake. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
- at least one control unit switchable between an operative condition where the at least one control unit is in an on state and an inoperative condition where the at least one control unit is in an off state;

38. A method of actuating at least one of an automatically actuatable torque transmitting system and an automatically actuatable transmission system in a power train of a motor vehicle by way of at least one control unit which is switchable between an operative condition where the at least one control unit is in an on state and an inoperative condition where the at least one control unit is in an off state, which is connected with at least one of the systems by at least one actuating means, and which receives signals from sensors arranged to monitor various activities of an operator of the vehicle, comprising the steps of switching the at least one control unit from the inoperative to the operative condition in response to a sensor signal denoting a starting by the operator of a prime mover of the vehicle;
- and switching the at least one control unit from the inoperative to the operative condition in response to a sensor signal denoting an activity of the operator other than starting of the prime mover.
