Abstract: A motor vehicle transmission system blocks the disengagement of the clutch (14) and the shifting of the transmission (12) into neutral for starting the engine (10), if the transmission is already in gear at the time the system is switched on. The blocking is canceled if the main brake (58) is applied and the application of the brake (58) is confirmed by a brake sensor (56), or if the driver moves a shifter element (24) from a non-neutral shift-gate position to the neutral shift-gate position after the system has been turned on.

Abstract: An automated multi-ratio transmission has a gear-engaging mechanism with a first actuator to move a selector member in a first direction to select a gear ratio, and a second actuator to move the selector member in a second direction to engage the selected gear ratio. The vehicle may be started from stand-still in either a forward or reverse start-up gear ratio, both of which are engaged from an end position of the range of movement of the selector member. In the start-up phase of the vehicle, an automated control means drives the first actuator to the appropriate selector position for either the forward or reverse start-up gear and then drives the second actuator to engage the desired start-up gear.

Abstract: A torque-transmitting system for vehicles has a main drive clutch operable by means of a clutch-actuator, a transmission, a shift mechanism for setting the transmission ratio, a selector lever allowing the driver to select between a neutral mode or a drive mode of the transmission, and electronic control means for controlling the clutch actuator and the shift. mechanism. The electronic control means will cause the clutch-actuator to disengage the clutch when the engine is started and to re-engage the clutch if the transmission has been left in neutral mode for a preprogrammed time period while the vehicle is standing still, so as to turn the input shaft of the transmission and thereby warm up the transmission oil.

Abstract: A vehicle transmission system has a main drive clutch (14) with a clutch-actuator (20, 22, 38), a transmission (12) with a gear-engaging mechanism (25), a driver-operable gear-selector lever (24), and an electronic control means (36) to control the clutch-actuator (20, 22, 38) and the gear-engaging mechanism (25). When the vehicle is started up from a standstill condition, the control means disengages the clutch and automatically shifts the transmission into a predetermined start-up gear. According to the invention, the electronic control means (36) is designed to allow the driver to operate the gear-selector lever (24) to select a higher start-up gear than the predetermined start-up gear that is selected automatically by the electronic control means.
