A method for turning off an internal combustion engine (ICE) where a clutch arrangement has first and second clutches that respectively couple the ICE to first and second input shafts of a transmission. The input shafts are drivingly connected to first and second sets of gears, respectively. The sets of gears are connected to an output shaft of the transmission. The method includes: controlling the ICE in an idling state when the vehicle is in standstill, wherein the clutches are in open positions; engaging the first input shaft with a first pre-selected gear, and engaging the second input shaft with a second pre-selected gear; initiating an engine turning off command; stopping the ICE by at least partly closing the clutches for simultaneously introducing torque transfer to the clutches into a transmission tie-up state for a controlled engine stop, wherein engine inertia of the ICE is captured in the clutches.

A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

A hybrid vehicle includes an engine that drives first wheel, and a motor that drives second wheel. The hybrid vehicle includes (1) a minute speed launch support mode where the hybrid vehicle is driven only by the motor as a drive source, (2) a sudden launch support mode where the hybrid vehicle is driven by the engine and motor as the drive source, and (3) a smooth launch support mode where the hybrid vehicle is driven only by the motor as the drive source in an early stage, is driven by the engine and motor in a middle stage, and is driven only by the engine in a late stage, and if an operation amount of an acceleration instruction unit is not 0 or is substantially not 0, any one of the support modes is executed according to an operation status of the acceleration instruction unit.

A system for comparing driver intent and a gear setting of a vehicle comprises a driver monitoring system including at least one driver monitoring sensor configured to capture attributes of the driver indicative of driver intent regarding an intended direction of travel. The system also comprises an evaluation processor configured to access driver data from the driver monitoring system. The evaluation processor is also configured to generate a mismatch signal in response to determining a mismatch between the driver intent and a gear setting of the vehicle. The evaluation processor may also be configured to control braking and/or acceleration of the vehicle in response to determining a mismatch between the driver intent and a gear setting of the vehicle. The system may also use data regarding an object within a threshold distance from a front or a rear of the vehicle, and/or a requested acceleration above a threshold amount.

Methods and systems for operating a torque converter clutch of an automatic transmission are presented. In one non-limiting example, the torque converter clutch is closed to provide a threshold torque capacity during a vehicle launch. If an engine torque request is less than the threshold torque capacity, the torque converter clutch remains closed.

A method of controlling launch of a vehicle, may include setting step in which a controller sets a basic target engine speed; a transient control step in which the controller controls a clutch torque based on the basic target engine speed; a transient state determining step in which the controller determines, whether a transition period of change of the engine speed elapsed; a first correction amount determination step in which the controller determines a correction amount; a correction applying step in which the controller adds the correction amount to the predetermined target engine speed and then determines a final target engine speed; an error determination step in which the controller determines the engine speed control error; and a feedback determination step in which the controller uses the engine speed control error and determines a feedback control amount for feedback-controlling a clutch actuator.

A method for accelerating a vehicle from rest, including controlling an engine according to a first control strategy; receiving a mode indication selecting a launch control mode for accelerating; controlling the engine according to a second control strategy; in response to greater than zero accelerator position, controlling to increase throttle valve opening and engine control operational conditions to limit engine torque output; while in the second control strategy, receiving an indication to end control by the second control strategy; and in response to indication, controlling according to the first control strategy causing the vehicle to accelerate from rest, the first acceleration rate greater than the second rate corresponding to accelerating from rest after sequentially controlling according to the first and second control strategies; the second acceleration rate corresponding to accelerating from rest by controlling according to the first control strategy without previously controlling according to the second control strategy.

A control system of a four-wheel drive vehicle and a gradient value setting device of the vehicle is provided so as to reliably control a wheel skid despite the vehicle facing an intersecting direction intersecting a maximum tilt line direction. The vehicle includes an engine, front and rear wheels, an electronic control 4WD coupling, and a control unit. The distribution amount of the driving force to the rear wheels is set by the electronic control 4WD coupling. The control unit determines whether or not the vehicle faces the intersecting direction on the inclined road, and if so, sets the driving force distribution amount so that the difference between the driving force distribution amount to the front wheels and to the rear wheels is smaller as compared with on a flat road, and commands the electronic control 4WD coupling to distribute the driving force by the distribution amount.

The disclosure relates to a control system for manoeuvring an automated vehicle, wherein the control system comprises one or more obstacle detection sensors which are configured to detect if an intended travelling path of the automated vehicle is free from obstacles or not during manoeuvring of the automated vehicle, and wherein the control system is further configured to utilize a plurality of predefined obstacle detection modes during manoeuvring of the automated vehicle, wherein the plurality of predefined obstacle detection modes have different levels of obstacle detection accuracy, wherein, the control system is further configured to select a specific obstacle detection mode from the plurality of predefined obstacle detection modes based on a specific driving mission and/or based on a specific area of operation for the automated vehicle so that the specific obstacle detection mode is used during the specific driving mission and/or in the specific area of operation.

Techniques are described for determining weight distribution of a vehicle. A method of performing autonomous driving operation includes determining a vehicle weight distribution that values for each axle of the vehicle that describe weight or pressure applied on a respective axle. The values of the vehicle weight distribution are determined by removing at least one value that is outside a range of pre-determined values from a set of sensor values. The method further includes determining a driving-related operation of the vehicle weight distribution. For example, the driving-related operation may include determining a braking amount for each axle and/or determining a maximum steering angle to operate the vehicle. The method further includes controlling one or more subsystems in the vehicle via an instruction related to the driving-related operation. For example, transmitting the instruction to the one or more subsystems causes the vehicle to perform the driving-related operation.
