A motor vehicle cruise control system includes: an arithmetic unit configured to calculate a physical momentum of a traveling device for achieving a target motion of a motor vehicle that is traveling along a traveling route generated, based on an output from a vehicle exterior information acquisition device; and a device controller configured to generate, and output, an actuation control signal for the traveling device in the motor vehicle, based on an arithmetic result obtained by the arithmetic unit. Driving operation information on an operation performed by a driver is input to both the arithmetic unit and the device controller in parallel. The arithmetic unit is configured to reflect the driving operation information in a process of determining the target motion. The device controller is configured to reflect the driving operation information in the control of the actuation of the traveling device.

A driving support ECU 10 determine that a mistaken acceleration operation condition is satisfied when a time from a first time point to a second time point is equal to or shorter than a predetermined threshold time (T2th), while a shift position is at a reverse position (R) for driving the vehicle backward. The first time point is a time point at which the driver does not operate the brake operation member. The second time point is a time point at which an index value corresponding to an acceleration operation amount satisfies a predetermined index value condition to be satisfied when the driver performs a predetermined sudden operation of the acceleration operation member. The driving support ECU make the driving force when the mistaken acceleration operation condition is satisfied smaller than the driving force when the mistaken acceleration operation condition is not satisfied.

A mild hybrid vehicle and a method of controlling the same are provided. The mild hybrid vehicle includes a sensor that detects shift intention of a driver to provide the shift intention as sensing information, a controller that determines a target rotation speed of an MHSG based on the sensing information and controls the MHSG based on the target rotation speed, and the MHSG that controls the rotation speed of the engine under control of the controller when the shift intention is detected.

Disclosed is a method of controlling a hybrid electric vehicle having a transmission, an engine, and first and second drive motors. The method includes: performing charging through the first drive motor using the power of the engine by engaging an engine clutch disposed between the engine and the first drive motor while a vehicle is stopped with the gear stage shifted to the parking (P) range; turning off the engine and controlling the clutch of the transmission to enter an open state when the gear stage is shifted to the driving (D) range; and commencing movement of the vehicle using the second drive motor alone or using at least one of the first drive motor or the engine together with the second drive motor based on at least one of requested torque, available torque of the second drive motor, or the speed of the first drive motor.

A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system includes: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.

A method of estimating a load on a vehicle (10), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

One way to improve fuel efficiency of a vehicle is to detect the vehicle operational shortcomings related to fuel consumption by determining whether fuel used during operation of the vehicle is normal fuel use or wasted fuel use. Considerations of idling, speeding and inappropriate gear shifts are some ways to measure the amount of fuel wasted due to operator shortcomings. Communicating this information to the operator in real-time so adjustments can be made will improve vehicle fuel efficiency. These techniques are applicable to tracking employment of other driving best practices as well.

An ECU executes processing including a step of counting up a duration Ntime when a Ready-On state is brought, and a shift position is an N position, a step of counting up a duration Not_Ntime when the duration Ntime is equal to or greater than a threshold value A, the duration Ntime is greater than a threshold value C, and the shift position is other than the N position, a step of resetting the duration Ntime and the duration Not_Ntime to initial values in a case where the duration Not_Ntime is greater than a threshold value D, and a step of executing warning processing when the duration Ntime is greater than the threshold value A.

A method and a system for a vehicle comprising: one or more power sources including at least one electrical machine; and a drivetrain for transferring torque between the one or more power sources and at least one drive wheel of the vehicle. The method comprises: controlling, when no positive drive torque (T.sub.drive) is transferred from the drivetrain to the at least one drive wheel, the at least one electrical machine to provide a backlash torque (T.sub.backlash) to the drivetrain, the backlash torque (T.sub.backlash) having a controlled value for turning the drivetrain if there is a backlash present in the drivetrain.

A control method for an electrically driven road vehicle comprising the steps of: providing an electric powertrain system; determining a plurality of first virtual gears for a boost configuration and/or a plurality of second virtual gears for a release configuration; detecting, following actuation of an interface system by the driver, while driving, a first selection for one of the first virtual gears and/or a second selection for one of the second virtual gears; and delivering, in the boost configuration, a drive torque to the at least two wheels as a function of the first selection; or delivering, in the release configuration, an anti-motive torque to the at least two wheels according to the second selection.
