An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

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.

An engine control device for an electric vehicle having an electrical rotating machine, includes: an engine control unit determining an engine rotational speed and an engine torque such that a particulate number of particulate matter per unit gas quantity that the engine releases into an atmosphere becomes equal to or less than a target value having been set in association with a warm-up state of the engine, the engine rotational speed, and the engine torque, and such that the engine rotational speed when a vehicle speed is less than a threshold value is lower than the engine rotational speed when the vehicle speed is equal to or more than the threshold value, and controlling the engine based on the determined engine rotational speed and the engine torque.

A method for controlling wheel slip of a vehicle. The vehicle comprises at least a first and a second motion support device, MSD, for providing torque to a common wheel of the vehicle. The method comprises receiving a wheel torque request. Based on the received wheel torque request, the method further comprises controlling the first MSD to provide torque to the wheel in a first mode of operation, and controlling the second MSD to provide torque to the wheel in a second mode of operation which is different from the first mode of operation. The controlling of the first MSD and the controlling of the second MSD are, at least temporarily, performed simultaneously.

A vehicle power system includes a battery bus between a traction battery and voltage converter, a high-voltage bus between the voltage converter and an inverter, and a controller. The controller, responsive to a contactor between the traction battery and voltage converter opening, controls an engine to maintain a speed of a generator electrically coupled with the inverter within a predefined range, controls the voltage converter to drive a measured voltage of the battery bus toward a first commanded value based on a first difference between the first commanded value and measured voltage of the battery bus, and controls the generator to drive a measured voltage of the high-voltage bus toward a second commanded value different than the first commanded value based on the first difference and a second difference between the second commanded value and the measured voltage of the high-voltage bus.

An embodiment system for controlling power consumption of a high voltage battery includes a driver's requested torque determiner configured to determine a driver's intention to accelerate a vehicle and to calculate a driver's requested torque, an available power amount calculator configured to calculate an available power amount of a difference between an existing power consumption amount of electronic components configured to use the high voltage battery as a power source and a minimum power consumption amount of the electronic components required by a vehicle system, and a driving controller configured to variably control power applied to the electronic components and power applied to a drive motor of the vehicle upon determining the driver's intention to accelerate the vehicle.

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.
