20190291593 · 2019-09-26 ·

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 trailer, a tractor-trailer configuration, 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.

20190275899 · 2019-09-12 · ·

A fuel cell system mounted on a vehicle comprises a fuel cell; a secondary battery; a drive motor configured to serve as a motor to generate a driving force and as a generator to generate regenerative power; an auxiliary machine configured to consume the regenerative power; an accelerator pedal sensor; a shift position sensor; a vehicle speed sensor; and a controller. The controller determines that the vehicle is in a first state when the vehicle has a negative vehicle speed, a move forward request is given to the vehicle and an accelerator pedal is depressed or when the vehicle has a positive vehicle speed, the move backward request is given to the vehicle and the accelerator pedal is depressed. When a predetermined first condition including a condition that the vehicle is in the first state is satisfied, the controller performs an auxiliary machine consumption process that causes the auxiliary machine to consume the regenerative power that includes a required power for the drive motor calculated by using a depression amount of the accelerator pedal.

GPS assist in regenerative braking

A regenerative braking system and method are disclosed. According to certain embodiments, the regenerative braking system is engaged and adjusted when the navigation system recognizes that the vehicle is descending down a long grade. This can be pre-stored information, or information derived from prior experience or from the shared experiences of other drivers. The regenerative braking system does not engage to the full stop of the vehicle, but instead can release at approximately three mph and allows friction braking to handle the rest of the stop. The navigation system in this embodiment recognizes that a stop sign or other full-stop situation is present.

CONTROL SYSTEM FOR ELECTRIC VEHICLES

When an electric vehicle is traveling downhill, experiencing regenerative braking, or otherwise forcing the vehicle motor to turn faster than the commanded motor torque, the vehicle motor produces electrical energy that can be used to recharge a vehicle battery. However, if the vehicle battery is already nearly or fully charged, the excess electrical energy produced may damage the battery. Control systems described herein may reduce and/or dispose of the excess energy by manipulating the motor flux (i.e., direct) current and quadrature current independently.

Navigation-enhanced battery state of charge maintenance

Systems and methods provide control the amount of battery SOC of a hybrid vehicle prior to reaching a downgrade section of roadway in order to offset the amount of energy that the hybrid vehicle will recuperate when traveling the downgrade. Navigation systems and methods are used to identify upcoming road conditions, such as downgrades. In this way, the battery SOC of the hybrid vehicle can maintain the capacity to allow a motor of the hybrid vehicle to assist in decelerating the hybrid vehicle during the downgrade if need be. Additionally, a situation where the battery is fully charged before reaching the end of the downgrade is avoided, which if not, could result in overcharging the battery, or having to switch to an engine-only mode of travel, where a driver must supplement engine braking with friction braking.
