  • Patent number: 9827999
    Abstract: This application discusses various ways to adjust the performance of a variable input control in accordance with previous use data. In some embodiments, the previous use data can be associated with particular users of the variable input control. In this way, a response provided by the user input control can be adjusted to accommodate particular patterns of use on a user by user basis. In some embodiments, the variable input control can take the form of an accelerator pedal of a vehicle. Performance of the accelerator pedal can be adjusted by changing an amount of engine power provided for a particular accelerator pedal position. The adjustment can arrange commonly utilized power settings in the middle of the accelerator pedal range of motion to make manipulation of the accelerator pedal more comfortable and convenient for each user of the accelerator pedal.

  • Patent number: 9777649
    Abstract: In an alcohol concentration estimation apparatus for an engine, a first crank angular speed (?1) within a first predetermined interval overlapping with the compression top dead center is calculated, and a first variation amount (??1) is calculated by subtracting ?1 from an average engine speed. A second crank angular speed (?2) within a second predetermined interval overlapping with the combustion bottom dead center is calculated, and a second variation amount (??2) is calculated by subtracting ?1 from ?2. In a relationship between air fuel ratio A/F and an indicated mean effective pressure (IMEP)/charging efficiency (?c) of the engine when the engine is operated with a predetermined fuel injection map indicating a relationship between A/F and IMEP/?c for each desired alcohol concentration, IMEP/?c is substituted by ??2/??1 ratio to estimate an alcohol concentration in fuel. The alcohol concentration estimation apparatus eliminates requirement of sensors for detecting an intake air mass.

  • Patent number: 9014942
    Abstract: An idling stop device installed in a vehicle includes a microcomputer, a detector, a storage, and a controller. The microcomputer automatically stops an engine of the vehicle when a prescribed stopping condition is satisfied, and automatically activates a starter motor of the engine when a prescribed activating condition is satisfied. The detector detects whether a drive voltage of the microcomputer, which is obtained by dropping a voltage of a battery of the vehicle is less than a threshold value. The storage stores, irrespective of a state of the microcomputer, information indicating that the detector has detected that the drive voltage is less than the threshold value. The controller drops an increasing speed of a current for driving the starter motor when the microcomputer activates the stator motor under the condition that the information is stored in the storage.

    Abstract: A motor vehicle has a drive device, a control device for starting and turning off the drive device and a detection device for monitoring the presence of a person in the motor vehicle. The control device is designed to turn off the drive device if the detection device signals that the person leaves or has left the motor vehicle. The control device is also set up to restart the drive device, after it has been previously detected that the person has gotten out of the motor vehicle, if the detection device signals the presence of a person again.

  • Patent number: 9008942
    Abstract: A method of managing an engine failure on a rotary wing aircraft (1) having a hybrid power plant (5) with at least two fuel-burning engines (13, 13?), at least one electric machine (12), and a main gearbox (11). Said aircraft (1) also has electrical energy storage means (14) and a main rotor (2) mechanically connected to said hybrid power plant (5). In said method, during each flight, the operation of said engines (13, 13?) is monitored in order to detect a failure of any one of them, and then once a failure of one of said engines (13, 13?) has been detected, said electric machine (12) is controlled, if necessary, to deliver auxiliary power We in order to avoid a deficit appearing in the total power WT of said hybrid power plant (5), thereby enabling the pilot of said aircraft (1) to fly said aircraft (1) safely without degrading said hybrid power plant (5).

  • Patent number: 9008941
    Abstract: The present invention relates to an anti-jerk control apparatus and method for an Hybrid Electric Vehicle (HEV). The anti-jerk control apparatus includes a model speed calculation unit for calculating a model speed of the motor in a state in which a vibration of a drive shaft is not considered. A vibration occurrence determination unit detects a speed vibration component while calculating a reference speed difference and an average speed difference from differences between the model speed and an actual speed of the motor, thus determining whether a vibration occurs on the drive shaft. A torque correction value calculation unit calculates a motor torque correction value for anti-jerk required to damp the vibration of the drive shaft, and controls torque of the motor if the vibration occurrence determination unit determines that the vibration occurs on the drive shaft.

  • Patent number: 9008939
    Abstract: A vehicle control system and method combining control allocation and phase compensation for forming a phase compensated actuator command signal based on a control demand signal. A feedback unit includes a matrix multiplication unit for forming an estimated behavior signal, from a control efficiency matrix and the actuator command signal. The estimated behavior signal is fed to a second summation unit for forming a difference signal. The difference signal is processed by a filter unit for forming a feedback signal which is connected to a first summation unit for forming a modified control demand signal, such that the modified control demand signal is adjusted to always represent a control demand realizable by the vehicle. The modified control demand signal is further connected to the second summation unit and to a control allocator which output is then connected to the matrix multiplier to form a feedback loop.
