Regeneration power control
A hybrid vehicle using an engine driving a generator to supply power to electric drive motors through a system power bus, and a method for controlling power regeneration in a hybrid vehicle are disclosed. Ground drive controllers associated with the drive motors are configured to determine a slope of a surface on which the vehicle is driving and set a maximum downhill speed of the vehicle based thereon. A generator controller, in response to the drive motors generating power through regenerative braking, regulates power on the bus by directing the generated power to recharge the battery when the battery has capacity, reducing an output of the generator to the bus when the battery is fully charged, and driving a driveshaft to drive the engine with the generator to consume excess power on the bus when the generator output is reduced to zero.
DYNAMICALLY ASSISTING HYBRID VEHICLES
A system includes a computing device with memory configured to store instructions and a processor to execute the instructions for operations that include receiving information representative of an amount of energy stored over a first period of time in an energy storage device of a vehicle that includes a first propulsion system. Operations include receiving information representative of a performance measure of the vehicle for a second period of time, shorter than the first period of time, and, determining an assistance adjustment from an estimated value of stored energy from the information representative of the amount of energy stored over the first period of time. Operations include determining a level of assistance for a second propulsion system included in the vehicle from the received information representative of the performance measure, and, adjusting the level of assistance using the assistance adjustment determined from the estimated value of the stored energy.
