The speed control device is equipped with: an actual speed acquisition unit; an actual position acquisition unit; an acceleration/deceleration control unit; and a travel resistance calculation unit. When in a situation in which an target speed increases from a first target speed to a second target speed, the target speed in the second road section is set such that an actual speed increases with a first-order lag from the first target speed to the second target speed over a period between the start position and end position of the second road section, and the target speed in the second road section is set such that the amount of change in the speed, which increases with the first-order lag, with respect to the travel time of the vehicle is decreased as the travel resistance calculated by the travel resistance calculation unit increases.

A hybrid vehicle includes two drive sources and two clutches, and is switchable between a neutral mode and a parallel mode during vehicle traveling. The two drive sources are both disconnected from drive wheels in the neutral mode, and are both connected to the drive wheels in the parallel mode. A control method for the hybrid vehicle includes implementing at least one of a first switching control and a second switching control. The first switching control includes, upon switching from the neutral mode to the parallel mode, implementing two synchronization controls on rotational speeds before and after the two clutches, concurrently during at least a partial period. The second switching control includes, upon switching from the parallel mode to the neutral mode, implementing two controls to cause transmitted torques of the two clutches to respectively approach zero, concurrently during at least a partial period.

Systems and methods are disclosed for determining, and displaying, the regulatory compliance status of a motorized vehicle, a driver of a motorized vehicle, or a non-vehicle machine. An authorized agent, such as a law enforcement officer, can perform a remotely-initiated safe stop of a motorized vehicle to prevent a high-speed chase. A system management center can receive, store, and transmit regulatory compliance records indicating the regulatory compliance status of drivers, motorized vehicles, and non-vehicle machines. A motorized vehicle can detect, and report, a driver tail-gating the motorized vehicle. The regulatory compliance history of drivers, motorized vehicles, and non-vehicle machines can be queried by authorized users.

Dynamic throttle pedal filtering of a vehicle is provided. An automated throttle filtering system may be included in the vehicle that may operate to filter throttle pedal input based on detection of a rough driving surface. The rough driving surface detection may be based on an evaluation of wheel speed signals or an indication of traction loss. The throttle pedal input may be filtered corresponding to rough driving surface magnitude values determined based on the wheel speed signals. For example, filtered torque demand values may be determined based on the rough driving surface magnitude values and included in a torque demand request communicated to the vehicle's powertrain system. The resulting torque output may modulate an undesirable oscillating torque demand that may be generated in relation to operation of the vehicle on a rough driving surface.

A power control ECU controls electric power and engine power of a hybrid vehicle. The power control ECU includes a request driving force calculating portion that calculates a request driving force calculated in accordance with an accelerator operation amount, a travel driving force calculating portion that calculates a travel driving force as a value that belatedly follows the request driving force, and a dashpot control processing portion. The dashpot control processing portion sets a value of the request driving force as a value of a final request driving force used to calculate request engine power when a difference of the request driving force with respect to the travel driving force is less than a predetermined positive value, and sets a value that belatedly follows the request driving force when the difference is greater than or equal to the predetermined positive value.

A method and system for blending between different torque maps of a vehicle in a smooth and progressive manner. Blending is delayed if the vehicle driver cannot detect that blending is taking place, for example, when the difference between a source map and target map is below a predetermined threshold.

An electric vehicle includes a vehicle controller. The vehicle controller is capable of switching a traveling mode of the electric vehicle between a first traveling mode and a second traveling mode that applies driving-force maps for enhancing a rough-road capability from a rough-road capability in the first traveling mode. The vehicle controller is capable of switching the traveling mode to the second traveling mode in forward traveling and in backward traveling and is configured to apply, to the backward traveling in the second traveling mode, a first driving-force map of the driving-force maps, the first driving-force map having gentler characteristics than a second driving-force map of the driving-force map applied to the forward traveling in the second traveling mode.

A driving system for a vehicle includes an engine including a fuel injection valve, an electric motor, a hydraulic clutch which connects/disconnects the engine to/from the motor, a hydraulic pressure sensor which detects hydraulic pressure of the clutch, and a controller which selectively executes one of a motor travel mode where the motor is activated and the engine is stopped, and an engine travel mode where at least the engine is activated. In a startup of the engine accompanying a change from the motor travel mode to the engine travel mode, the controller causes the clutch to transition from a disconnected state to a connected state, determines the connected state of the clutch based on hydraulic pressure detected by the hydraulic pressure sensor, and when the clutch is confirmed to be in a predetermined connection initial state, the controller causes the fuel injection valve to inject fuel.

An active vibration reduction control apparatus for a hybrid electric vehicle includes: a reference signal generator generating a reference signal and a first phase based on a first rotational angle of a first motor; a vibration extractor extracting a vibration signal from a second motor; a coefficient determiner determining a filter coefficient which minimizes a phase difference between the reference signal and the vibration signal; a phase determiner detecting a second phase which corresponds to the phase difference using a first speed signal of the first motor and the filter coefficient; a phase deviation amount detector detecting a third phase for compensating for a phase delay; and a synchronization signal generator generating an antiphase signal of a shape of an actual vibration in order to determine a compensating force of the first motor.

A vehicle includes an engine. The vehicle includes a controller configured to start a timer having a duration defined by a charge limit of a traction battery and during which the engine braking is maintained and reduce a predetermined rate of change speed limit of the engine is reduced. The starting of the timer is responsive to application of an accelerator pedal during engine braking. The controller is further configured to increase the predetermined rate of change speed limit such that engine braking is predicted based on the limit of the battery, responsive to application of an accelerator pedal during engine braking.
