  • Patent number: 11377087
    Abstract: Since a supercharging pressure from a supercharger decreases when an actual rotation speed difference is equal to or less than a margin rotation speed difference, a response delay of an engine torque due to a response delay of the supercharging pressure in a high rotation curbing control unit can be appropriately curbed. A shortage of the engine torque with respect to a required engine torque due to a decrease in the supercharging pressure by a supercharging pressure decreasing unit is compensated for using an torque of a second rotary machine. Accordingly, it is possible to curb a decrease in power performance due to a decrease in the supercharging pressure and to prevent an engine rotation speed from falling into a high-rotation state in which the engine rotation speed exceeds a maximum rotation speed.

A controller is configured to execute a first determination to determine that a required power is less than a reference power, and a second determination to determine that a condition to start an engine is satisfied. If the answers of the first determination and the second determination are YES, a target power of the engine is set to a predetermined power which is greater than the required power, and which can be generated by consuming smaller amount of fuel. Then, the generator is driven by the engine being operated to achieve the predetermined power, and an electric power generated by the generator to be accumulated in a battery is set to a value calculated based on a difference between the target power and the required power.

  • Patent number: 11351979
    Abstract: Through-the-road (TTR) hybrid designs using control strategies such as an equivalent consumption minimization strategy (ECMS) or an adaptive ECMS are implemented at the supplemental torque delivering electrically-powered drive axle (or axles) in a manner that follows operational parameters or computationally estimates states of the primary drivetrain and/or fuel-fed engine, but does not itself participate in control of the fuel-fed engine or primary drivetrain. BSFC type data particular to the paired-with fuel-fed engine allows an ECMS implementation (or other similar control strategy) to adapt to efficiency curves for the particular fuel-fed engine and to improve overall efficiencies of the TTR hybrid configuration.

  • Patent number: 11351872
    Abstract: The disclosed principles provide for acceleration systems and related methods for use with power assisted vehicles, such as E-Bikes. Disclosed systems and methods provide for a quick ramp up feature that accelerates the vehicle at a predetermined acceleration rate, but then smoothly integrates into the target cruising speed of the current speed mode by incrementally reducing the rate of acceleration as the vehicle approaches the target cruising speed, thereby reducing or eliminating any jolt or jerky feeling felt during the transition from acceleration to target cruising speed.
