Driving assistance apparatus
When a driver is not in pedal erroneous operation inducing situation and a rate of change in an operation amount of an accelerator pedal is equal to or greater than a first erroneous operation determination threshold value, a driving assistance apparatus determines that operation of the accelerator pedal is erroneous operation. When the driver is in the pedal erroneous operation inducing situation and the rate of change in the operation amount of the accelerator pedal is equal to or greater than a second erroneous operation determination threshold value, the riving assistance apparatus determines that the operation of the accelerator pedal is the erroneous operation, and the second erroneous operation determination threshold value is smaller than the first erroneous operation determination threshold value.

CONTROLLABLE ELECTRIC VEHICLE AND A CONTROL SYSTEM THEREFOR
A modular electric vehicle comprising a single module(s) with an electric driving system and a vehicle control unit, the modular vehicle is configured to be selectively articulated to a master vehicle and to be controlled from a selectable control source via the vehicle control unit either in a first, articulated mode, or in a second, autonomous mode. The control source may be selected to be in communication with a first gateway installed at the master vehicle or a second gateway installable at the modular vehicle. The modular electric vehicle may comprise a pair of single modules coupled to one another in tandem and in data and control communication with one another. The modules may each be configured to serve a master or a slave vehicle, so that any of the modules may serve a master vehicle, whenever required for the autonomous mode.

VEHICLE ENERGY MANAGEMENT SYSTEM AND RELATED METHODS
A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a truck, a tractor unit, a trailer, a tractor-trailer configuration, at a tandem, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

cle is selected and activated by the driver model from a number of vehicle statuses (301, 303, 305, 307, 309) by comparing a current status of the vehicle with at least one selection condition specified for a particular vehicle status, the number of vehicle statuses (301, 303, 305, 307, 309) comprising at least a first vehicle status (301, 303, 305, 307, 309) and a second vehicle status (301, 303, 305, 307, 309). Furthermore, the driver model, on activation of a particular vehicle status (301, 303, 305, 307, 309), enables at least one control command assigned to the vehicle status (301, 303, 305, 307, 309) for modifying a setting of the vehicle, wherein a plurality of changes are made by the driver model between a currently activated vehicle status (301, 303, 305, 307, 309) and at least one further vehicle status (301, 303, 305, 307, 309) and, for at least one change of the plurality of changes, a coasting status (303), in which the vehicle is coasting, is activated before any activation of the further vehicle status (301, 303, 305, 307, 309) by the driver model.
MOBILITY SERVICE MANAGEMENT SYSTEM
A mobility service management system manages a mobility service utilizing a mobility service vehicle that runs via a stop position. A stop position reservation database indicates a reservation status of each stop position. A reservation request includes a target stop position and a target stop time specified by a user. The mobility service management system determines, based on the stop position reservation database, whether the target stop position is available in a target stop period including the target stop time. When the target stop position is available in the target stop period, the mobility service management system reserves the target stop position in the target stop period for a first mobility service vehicle assigned to the user. The first mobility service vehicle runs in accordance with a first operation pattern that arrives and stops at the target stop position within the reserved target stop period.
