  • Patent number: 11731517
    Abstract: An electric vehicle includes first and second traveling motors, first and second rotational position sensors, and a measurement controller. The first rotational position sensor detects a rotation angle of the first traveling motor and has a first wheel-speed range in which a deviation of an original position of the first rotational position sensor is measurable. The second rotational position sensor detects a rotation angle of the second traveling motor and has a second wheel-speed range in which a deviation of an original position of the second rotational position sensor is measurable. The second wheel-speed range differs from the first wheel-speed range. The measurement controller executes, in an execution order, measurements of the deviations of the original positions of the first and second rotational position sensors while the electric vehicle is traveling, and switch the execution order on the basis of acceleration or deceleration data of the electric vehicle.

  • Patent number: 10308251
    Abstract: A transmission park mechanism is hydraulically actuated. Specifically a controller releases the parking pawl by commanding engagement of particular shift elements at an elevated line pressure. The process of transitioning from Park to a Drive or Reverse condition may involve several sequential steps. To reduce the delay between driver selection of Drive or Reverse and completion of the engagement, it is advantageous to raise the line pressure in response to depression of a brake pedal, prior to movement of the shift lever. To limit the adverse fuel economy impact of increased line pressure, the line pressure is lowered again if the driver does not move the shift lever soon after depressing the brake pedal.

  • Patent number: 9067593
    Abstract: A launch control system which maximizes hybrid vehicle acceleration from a standing start. A hybrid vehicle includes wheels, an engine, a motor-generator, a processor, and an actuation device. The processor controls an engine speed and an engine torque independently from a wheel speed and a wheel torque. While the hybrid vehicle is at a standstill, the actuation device is switched to an on state, and the engine speed and engine torque is raised to optimal values. When the actuation device is subsequently switched to an off state, the engine speed and the engine torque is applied to the plurality of wheels to launch the hybrid vehicle. The processor blends or further adjusts the torque applied to the plurality of wheels to maximize the acceleration while optimizing an amount of wheel slip. The processor then learns the launch to improve performance on subsequent launches.

  • Publication number: 20150148191
    Abstract: An engine-driven vehicle includes an energy recovery system (20) for recovering energy under braking of the vehicle. Under predetermined conditions, a controller selectively delivers recovered energy from a storage (24) via device (26) to motor the engine (12) above zero speed (e.g. at or above idle speed), preferably during engine fuel cut. The engine may be motored if the vehicle speed is below a threshold speed with zero torque demand for the vehicle driveline, or when the vehicle has been brought to a stop, for example. The step of delivering recovered energy to motor the engine (12) may be initiated if a door on the vehicle is opened or if a park brake on the vehicle is activated. Auxiliary systems are driven by the engine under influence of energy delivered from the energy recovery system to the engine when the vehicle is at rest. The energy recovery system may include a mechanical flywheel.

  • Patent number: 8123659
    Abstract: A method and a motor vehicle applying that method for preventing an uncontrolled rollback of a motor vehicle is suggested, said method comprising means for influencing the torque transmission by a drive train. In case a rollback action is detected, namely a movement in opposite direction as the predetermined direction of movement, the transmission of torque is influenced such that a torque is transmitted via the drive train acting against the rollback direction and the torque does not exceed a defined maximum value. The control allows a controlled rollback by making the intervention by the system to be perceived little disturbing, but at the same time in particular in case of strong incline of the road does not render the driver non-informed about the actual incline.

  • Publication number: 20110245037
    Abstract: An engine controlling apparatus for a motorcycle for reducing the output power of the engine when necessary includes a second controller for deciding, if a brake operation is detected based on an opening value of an accelerator grip detected by a potentiometer for detecting an opening value of the accelerator grip that the accelerator grip is in an open state, whether it is necessary to reduce the output power of an engine and for carrying out output power reduction control of the engine. If a front wheel brake sensor detects a brake operation for the front wheel and in addition it is decided from the speed value detected by a vehicle speed sensor that the motorcycle is not being decelerated, then the second controller decides that there is the necessity to reduce the output power of the engine and carries out the output power reduction control of the engine.

  • Publication number: 20110230309
    Abstract: A method is provided for automatic shutdown of an internal combustion engine in a motor vehicle, in particular in a vehicle having an automatic transmission, by way of a stop-start unit which automatically shuts down the internal combustion engine when the vehicle is decelerated to a standstill and kept at a standstill by operation of the brake pedal for a predetermined interval of time. Within the predetermined interval of time, the driver is given an opportunity to prevent the automatic shutdown. According to the invention, an automatic shutdown is prevented when the driver of the vehicle depresses the brake pedal fully within the predetermined interval of time and then releases the brake pedal again.

  • Publication number: 20110207579
    Abstract: A control system includes an auto-stop module, an auto-start module, and a starter module. The auto-stop module stops an engine when a brake pedal position is greater than a threshold position and a transmission is in a drive gear. The auto-start module starts the engine when the brake pedal position is less than a minimum position and the engine stop is initiated. When the engine start is initiated and an engine speed is greater than zero, the starter module engages a pinion gear of a starter with a ring gear of an engine by reciprocally actuating the pinion gear N times between a retracted position and an extended position, wherein N is an integer greater than two.

A method of spinning up the exhaust turbine during an interval between the time that the operator moves his/her foot from the brake pedal to the accelerator pedal to initiate a launch. A non-exhaustive list of actions that can be taken to increase exhaust enthalpy provided to the turbine include: opening the throttle, retarding the spark, and closing the wastegate. Additionally, a brake can be applied at one of the vehicle wheels to keep the engine from launching forward during this interval.

  • Patent number: 7949454
    Abstract: In a method for stabilizing a vehicle in extreme driving situations, in particular when understeering while cornering, multiple wheels are decelerated in order to reduce the driving speed. A maximum cornering force of the wheels and thus a minimal curve radius may be achieved if in particular the rear wheels are decelerated and a higher braking torque is applied on the rear wheels than on the front wheels and in the process in particular the outside front wheel remains highly underdecelerated.
