Electric motor scooters are disclosed. In one embodiment, an electric motor scooter includes an electric drive, an electric battery, an actuation unit, and a control unit. The actuation unit may be brought in to one of a plurality of positions along an actuation distance, and the control unit is configured to selective a drive mode depending on the position of the actuation unit along the actuation distance. The drive modes include a recuperation mode, a coasting mode, an acceleration mode, and a boost mode. When in the recuperation mode, at least a portion of the energy generated in the electric drive may be delivered to the battery.

A coasting neutral control apparatus associated with a speed camera may include a communication terminal configured to acquire speed camera enforcement section information, and a controller configured to perform or interrupt coasting neutral control by determining whether a predetermined execution condition for the coasting neutral control is satisfied using the speed camera enforcement section information.

A system and method for operating a hybrid vehicle having an engine and an eMachine coupled by a clutch using a hybrid controller is presented. The method determines an idle fuel rate of the engine, determines a hybrid efficiency index for the hybrid vehicle, determines an expected energy storage rate increase for an operating condition where the engine is decoupled from a vehicle transmission using said clutch, multiplies the expected energy storage rate increase by the hybrid efficiency index to determine an expected fuel rate reduction of the engine in the operating condition; and decouples the engine from the vehicle transmission using the clutch if the expected fuel rate reduction is greater than the idle fuel rate.

A driving assistance device (10) is mounted in a mobile body (100). An abnormality detection unit (22) detects an abnormality in a sensor mounted in a peripheral body moving on a periphery of the mobile body (100). An assistance determination unit (23) reads a control pattern corresponding to a sensing area of a sensor whose abnormality has been detected by the abnormality detection unit (22), from a pattern storage unit (31). A path generation unit (24) generates path data indicating a moving path of the mobile body (100) to correspond to the control pattern.

While a vehicle is coasting with an engine being automatically stopped and a power transmission path between the engine and wheels being disengaged, when a deceleration request is made and the engine is restarted with the power transmission path being engaged, a deceleration level increases relative to the deceleration level required by a driver or the vehicle, thereby lowering drivability. A vehicle control apparatus includes a deceleration level control unit that controls the deceleration level of the vehicle such that, during travelling of the vehicle continuing to travel with a power transmission mechanism between the engine and the wheels being disengaged, when the deceleration request is made and the engine is started by an engagement of the power transmission mechanism, the deceleration level becomes a target deceleration level calculated from a first target deceleration level generated after the engagement of the power transmission mechanism is complete and a second target deceleration level generated in response to the deceleration request.

A vehicle control apparatus includes an engine, a refrigerant compressor, a lock up clutch, a throttle valve, and first, second, and third deceleration controllers. The second deceleration controller controls the lock up clutch to a slip state and controls the throttle valve openwise on the condition that the refrigerant compressor is in the stopped state on decelerated travel of a vehicle in a second speed region in which a vehicle speed is lower than a first vehicle speed and higher than a second vehicle speed lower than the first vehicle speed. The second deceleration controller controls the lock up clutch to a disengaged state and controls the throttle valve closewise on the condition that the refrigerant compressor is in the operative state on the decelerated travel of the vehicle in the second speed region.

A vehicle control device for controlling a vehicle includes a drive source and an automatic transmission connected to the drive source and including a variator. The vehicle control device includes: a first control unit configured to execute a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state if a during-travel drive source stop condition is satisfied; and a second control unit configured to execute a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state if a during-travel drive source stop release condition is satisfied. The second control unit executes the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control if the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied.

Methods and systems for improving operation of a vehicle driveline that includes an engine and an automatic transmission with a torque converter are presented. In one non-limiting example, the engine may be stopped while a vehicle in which the engine operates is rolling. A transmission coupled to the engine may be shifted as the vehicle rolls so that vehicle response may be improved if a driver requests an increase of engine torque.

Provided are a travel control device, a vehicle, and a travel control method that reduce driver discomfort while making it possible to further improve the fuel economy of the vehicle. This travel control device controls switching of vehicle travel between propulsion travel whereby the vehicle is made to travel while maintaining the vehicle speed at a target speed and coasting travel whereby the vehicle is made to travel by inertia, and is equipped with a travel control unit that, in cases in which the vehicle speed during coasting travel has exceeded the allowable maximum speed of a prescribed range, switches travel of the vehicle from coasting travel to propulsion travel and causes the vehicle to brake, and once the vehicle speed has decreased to a prescribed speed that is above the target speed, releases braking of the vehicle.

A device for optimizing the electrical power generated by an electric machine in the coasting mode of a vehicle includes a module for computing a total regenerative torque or a variable proportional thereto, on the basis of which the electric machine is operated in generator mode. The module is configured to: compare the wheel slip that is present at at least one wheel of the vehicle to a predefined threshold value; reduce the total regenerative torque by a small amount when the ascertained wheel slip is less than the predefined threshold value; and increase the total regenerative torque by a small amount when the ascertained wheel slip is greater than the predefined threshold value. The reduction or increase takes place iteratively with multiple successive iteration steps.
