Systems and control methods can provide for determining a TrnAin torque request from desired vehicle acceleration in a vehicle that utilizes a WTC architecture to allow for smooth transition between different transmission states, such as torque converter bypass clutch states and shifts between transmission gear ratios. The methods provide consistent and smooth vehicle acceleration profile during transmission state transitions. The methods also provide the ability to track the desired vehicle acceleration consistently from virtual driver demand sources, such as adaptive cruise control, autonomous vehicle, or remote parking, without allocating any additional resource to account for transmission state transitions. The proposed methods are applicable to any TC-based automatic transmission drivetrain, such as conventional powertrain, MHT, P4 HEV, or even BEV powertrains where the motor is located on the impeller side of a torque converter.

A method for operating a single-track or multi-track vehicle including a driver-assistance system. In the method, a speed of the vehicle and a distance of the vehicle from a vehicle in front are controlled. The speed is controlled within a system-related speed range of the driver-assistance system using a position of an operating element of the vehicle and is controlled up to an optional target speed that is selectable within the speed range. Before an upper limit of the speed range is exceeded, a warning signal is provided to a driver of the vehicle. The distance is controlled within the speed range in a speed-dependent distance buffer region depending on the position.

Embodiments of the present invention provide a vehicle having different operating modes, and for each such mode a different characteristic of output torque and accelerator pedal position. The rise of output torque in response to a propulsion request is more or less delayed according to the instant operating mode. The invention provides for blending of the response to a propulsion request so that the delay is progressively varied between a source and target operating mode.

Disclosed is a driving assistance apparatus which includes an object information obtaining section for obtaining a piece of information regarding an object present ahead of a vehicle, an operation amount obtaining section for obtaining an accelerator pedal operation amount, and a control section. The control section predicts whether or not the vehicle will collide with the object on the basis of the obtained object information and executes collision avoidance assistance control for decelerating the vehicle at a predetermined demanded deceleration rate in the case where the control section predicts that the vehicle will collide with the object and an execution condition becomes satisfied as a result of the obtained accelerator pedal operation amount having become equal to or greater than a predetermined operation amount. The control section sets the demanded deceleration rate on the basis of the distance and the relative speed obtained when the execution condition becomes satisfied.

This vehicle control device is provided with: a control unit for executing one-pedal control, that is, the control for accelerating a vehicle when a single pedal is depressed from a predetermined reference point of a pedal stroke, and for decelerating the vehicle when the pedal is released from the reference point; and a determination unit for determining whether or not a rate of change in a pedal operation amount when the pedal is released is equal to or greater than a first threshold value. The control unit performs control for increasing a braking force when the rate of change is equal to or greater than the first threshold value.

A vehicle speed limiting apparatus includes an opening detection unit to detect an opening of an accelerator pedal of the vehicle; an estimation unit to estimate whether the vehicle starts a lane change; and an ECU to implement an upper-limit setting unit to set an upper-limit speed of the vehicle, a vehicle speed control unit to control the traveling speed so as not to exceed the upper-limit speed even when the opening of the accelerator pedal becomes great enough to make the traveling speed exceed the upper-limit speed, and a permissible speed setting unit to set a permissible speed higher than the upper-limit speed. When the estimation unit estimates that the vehicle starts the lane change, the vehicle speed control unit permits the traveling speed to exceed the upper-limit speed, and controls the traveling speed so as not to exceed the permissible speed.

A driving supporting apparatus comprises an acceleration operation element operated by a driver; and a control unit capable of performing an acceleration limiting control to control the vehicle in such a manner that an acceleration of the vehicle does not exceed a predetermined limiting acceleration. The control unit sets a distance threshold to a value varying depending on a kind of a front target object that is present in front of the vehicle, and performs the acceleration limiting control when a distance condition and an erroneous operation condition are satisfied. The distance condition is a condition that is to be satisfied when a distance between the vehicle and the front target object is equal to or shorter than the distance threshold. The erroneous operation condition is a condition that is to be satisfied when the driver is erroneously operating the acceleration operation element.

A system and method for controlling a vehicle powertrain including an engine and a motor operable to propel the vehicle includes reducing a torque of the motor at a first torque reduction rate from a torque level above a minimum motor torque in response to a deceleration request. A torque of the engine is reduced at a second torque reduction rate less than the first torque reduction rate in response to the deceleration request.

A collision avoidance device includes a collision avoidance executor, a determiner, and a collision avoidance controller, for example. The collision avoidance executor can execute a collision avoidance function for a vehicle to avoid collision with an object to be avoided. The determiner determines, based on an operation of an accelerator pedal by a driver, whether the driver has an intention of acceleration. The collision avoidance controller inhibits execution of the collision avoidance function when the driver is determined to have the intention of acceleration. The determiner further determines, based on the operation of the accelerator pedal, whether the driver has an intention of cancelation of the collision avoidance function. The collision avoidance controller ends the execution of the collision avoidance function when the driver is determined to have the intention of cancelation during the execution of the collision avoidance function.

Systems and methods for improving operation of a driveline disconnect clutch for a hybrid vehicle shifting are presented. In one example, pressure of a working fluid supplied to the driveline disconnect clutch is adjusted in response to a rate of change in accelerator pedal position. Further, pressure of the working fluid may be decreased responsive to selected operating conditions.
