Methods and systems are provided for controlling and diagnosing a mechanical vehicle component. In one example, a method may include determining a vehicle speed and a plurality of clutch position settings at a diagnostic controller, and identifying unauthorized conditions based on these determinations. Further, the diagnostic controller may trigger an active fault state of the mechanical vehicle component in order to avoid unauthorized conditions that may lead to unwanted or unanticipated changes in vehicle motion.

An electric delivery truck control system is disclosed. Sensors detect operation parameters associated with the electric delivery truck as the electric delivery truck maneuvers along the roadway. An electric delivery truck control unit detects electric delivery truck control inputs associated with an operation of the electric delivery truck. The electric delivery truck control inputs are generated from an operation of the electric delivery truck. An operation parameter controller automatically adjusts the operation of the electric delivery truck as the electric delivery truck maneuvers along the roadway to maintain the operation of the electric delivery truck within an operation threshold based on the detected driving parameters and the electric delivery truck control inputs. The operation threshold is the operation of the electric delivery truck that is maintained with an overall power storage of the electric delivery truck thereby enabling the electric delivery truck to execute a route by consuming power stored in the overall power storage of the electric delivery truck.

The invention relates to a method for setting a driving speed of a motor vehicle on a route. A control device of the motor vehicle sets the driving speed depending on an operating position limited by two extreme positions of a pedal device of the motor vehicle, which may be operated by a driver, wherein the control device detects the operating position of the pedal device, and depending on the detected operating position, determines in at least one specified driving mode a target driving speed corresponding to the respective operating position, and the control device sets the driving speed corresponding to the respective target driving speed by means of a closed loop control as long as the respective operating position is detected. The setting in this case takes place independently of a current condition of the route. The invention also includes a motor vehicle.

The present invention provides a shift control method implemented in a vehicle equipped with an automatic transmission for controlling an input shaft rotation speed to a target input shaft rotation speed during a shift. The method includes setting of a basic target synchronization rotation speed that is a basic target value of the input shaft rotation speed during the shift, and setting of a corrected target input shaft rotation speed as the target input shaft rotation speed when the shift is a downshift without a requirement for a driving force of the vehicle, The corrected target input shaft rotation speed is obtained by decreasingly correcting the basic target synchronization rotation speed. Further, a decreasing correction amount of the basic target synchronization rotation speed is set so as to become larger as a deceleration of the vehicle becomes larger.

A method and system for controlling an engine clutch of a P2 type parallel hybrid vehicle includes steps of: determining whether or not a learning mode entry condition is satisfied, depending on whether or not a kickdown shift occurs during performance of variable hydraulic control of an engine clutch and based on the degree to which slip of the engine clutch occurs, deriving and storing a learning hydraulic value for suppressing the slip that is to occur when the kickdown shift occurs during the performance of the variable hydraulic control in such a manner that the slip does not occur, when a vehicle state satisfies a predetermined learning mode entry condition, and computing a final hydraulic pressure by adding a hydraulic compensation value to a target hydraulic pressure, when the same kickdown shift situation occurs, and controlling the engine clutch using the computed final hydraulic pressure.

A method of controlling gear shifting in an electric vehicle includes: determining whether or not an electric vehicle travels in an electric vehicle (EV) traveling mode; determining whether or not kick-down gear shifting is required in the EV traveling mode; determining whether or not acceleration linearity control is possible, in a case where the kick-down gear shifting is required; performing correction of a torque of a motor in a case where the acceleration linearity control is possible; and performing gear shifting in a transmission on the basis of the corrected torque of the motor.

A control device for a vehicle includes a drive shaft, an engine coupled to the drive shaft, an electric motor coupled to the drive shaft, and a control unit. The control unit increases a torque of the electric motor when an accelerator pedal opening increases to equal to or more than a predetermined degree of opening during switching of driving sources, and decreases the torque of the electric motor while increasing the torque of the engine after a change of the torque of the engine turns to increase.

A device is provided for controlling longitudinal guidance of a vehicle designed to be driven in an at least partly automated manner. The vehicle includes an actuation element for having a driver control longitudinal guidance, the actuation element being blockable within predefined limit positions in accordance with a variable representing the degree of automation of the vehicle and a first condition. The actuation element can be unblocked in accordance with the variable representing the degree of automation of the traveling vehicle and at least one second condition.
